Role of veterinarians in modern food hygiene  

PubMed Central

Veterinary services and veterinary education and training must keep pace with the constantly changing patterns of agriculture and food processing. Changes in methods of animal production are associated with many problems of food processing and food quality. Veterinary supervision of the animal feed industry and of meat and distribution is essential. Quality testing of meat, milk, and eggs requires the introduction of suitable routine sampling systems, laboratory procedures, and complex evaluation procedures. Food hygiene problems have changed in recent years not only as a result of new methods of animal production, but also because of changes in food processing technology and in the presentation of food to the consumer, increased environmental pollution, increased international trade, and increased tourist travel. Food hygienists must adopt an active and progressive policy and change the scope of food control from a purely negative measure into a positive force working towards improved food quality and the avoidance of losses during production. A modern food hygiene programme should cover all stages of production, processing, and distribution of food and also other ingredients, additives and the water used for production and processing. Veterinarians should also be involved in the registration and licensing of enterprises and this should take into account the premises, the procedures to be used, new techniques in animal husbandry, machines and equipment, etc. In order to facilitate the microbiological analysis of foodstuffs, new mechanized or automated laboratory methods are required, and consideration must be given to adequate sampling techniques.

[Hygienic assessment of food products in Krasnoyrsk region].  


This article presents data on the prevalence of different types of sanitary violations, caused by failure to comply with sanitary regulations, on 573 enterprises that produce bakery products, confectionery, dairy, meat and fish products, drinks in the Krasnoyarsk Territory. It is shown that the greatest number of sanitary offenses are committed at manufactures of milk, fish and meat products. Finished goods at 21-37% of these enterprises do not meet the requirements of hygiene standards. The proportion of deposits of factors (such as type of food product, a form of ownership of the enterprise, the type of locality, where manufacture is) in the frequency of sanitary violations has been determined.

Raising food hygiene standards--could customer power and the new laws hold the key?  


In September 1995 new general food hygiene regulations came into force. The new law, quite rightly, requires proprietors of food businesses to focus their thoughts and actions on risks to food safety. Proprietors are required to identify and assess risks and ensure that adequate management procedures are put into place to ensure food safety. This is a welcome move as contributing factors in most cases of food poisoning involve poor food hygiene practices. At the same time there has been a large increase in the amount of advice and guidance to local authority enforcement officers, particularly to assess risks to food safety when considering what action to take in any situation - the lower the risk the less appropriate it is to take legal action. However, there are many conditions found in food premises which present little or no risk to health, such as routine cleanliness in non-high risk areas, but lower standards on these might be viewed by the public as inappropriate for food businesses. With an increasing amount of choice available to customers, proprietors and managers of food businesses need to be more aware than ever of the complex pattern of consumer demands including that of supplying a clean and safe product in its broadest sense. The notion of consumer sovereignty is not a new concept. Combined with the new laws could it hold the key to genuine improved standards in food hygiene? This article reviews the subject and draws attention to a research programme being undertaken at the University of Brighton to identify, compare and contrast factors which the public perceive as important in terms of food hygiene in public eating places with those considered important by professionals with an interest in the subject. The results could bring benefits to the catering industry and customers. PMID:8987337

Towards integrated hygiene and food safety management systems: the Hygieneomic approach.  


Integrated hygiene and food safety management systems in food production can give rise to exceptional improvements in food safety performance, but require high level commitment and full functional involvement. A new approach, named hygieneomics, has been developed to assist management in their introduction of hygiene and food safety systems. For an effective introduction, the management systems must be designed to fit with the current generational state of an organisation. There are, broadly speaking, four generational states of an organisation in their approach to food safety. They comprise: (i) rules setting; (ii) ensuring compliance; (iii) individual commitment; (iv) interdependent action. In order to set up an effective integrated hygiene and food safety management system a number of key managerial requirements are necessary. The most important ones are: (a) management systems must integrate the activities of key functions from research and development through to supply chain and all functions need to be involved; (b) there is a critical role for the senior executive, in communicating policy and standards; (c) responsibilities must be clearly defined, and it should be clear that food safety is a line management responsibility not to be delegated to technical or quality personnel; (d) a thorough and effective multi-level audit approach is necessary; (e) key activities in the system are HACCP and risk management, but it is stressed that these are ongoing management activities, not once-off paper generating exercises; and (f) executive management board level review is necessary of audit results, measurements, status and business benefits.

Sanitary Conditions of Food Vending Sites and Food Handling Practices of Street Food Vendors in Benin City, Nigeria: Implication for Food Hygiene and Safety  

PubMed Central

Objective. To determine the sanitary conditions of vending sites as well as food handling practices of street food vendors in Benin City, Nigeria. Methodology. A descriptive cross-sectional study was done using an observational checklist and researcher-administered questionnaire. 286 randomly selected vending units were surveyed, and their operators interviewed on their food handling practices. Results. A higher proportion, 259 (90.5%), of the observed vending sites appeared clean. The following sanitary facilities were observed in and around the respective food premises of the respondents: waste bin, 124 (43.4%), refuse dumpsite, 41 (14.3%), wash hand basin, 201 (71.2%), hand towel, 210 (73.4%), and soap, 220 (76.9%). There were also the presence of flies 118, (41.3%), and the presence of rats/cockroaches, 7 (2.4%). Respondents with tertiary education, 5 (38.5%), vended foods in environment with good hygiene status compared to those with secondary, 45 (31.7%), and primary education, 33 (27.3%). There was no statistically significant association between educational status and the hygiene status of food premise (P = 0.362). Conclusion. This study showed that street food vending sites in Benin City were sanitary and that food vendors had good food handling practices. PMID:25258630

Effect of a Manager Training and Certification Program on Food Safety and Hygiene in Food Service Operations  

PubMed Central

Food safety is an important public health issue in the U.S. Eating at restaurants and other food service facilities increasingly has been associated with food borne disease outbreaks. Food safety training and certification of food mangers has been used as a method for reducing food safety violations at food service facilities. However, the literature is inconclusive about the effectiveness of such training programs for improving food safety and protecting consumer health. The purpose of this study was to examine the effect of food manger training on reducing food safety violations. We examined food inspection reports from the Toledo/Lucas County Health Department (Ohio) from March 2005 through February 2006 and compared food hygiene violations between food service facilities with certified and without certified food managers. We also examined the impact on food safety of a food service facility being part of a larger group of facilities. Restaurants with trained and certified food managers had significantly fewer critical food safety violations but more non-critical violations than restaurants without certified personnel. Institutional food service facilities had significantly fewer violations than restaurants, and the number of violations did not differ as a function of certification. Similarly, restaurants with many outlets had significantly fewer violations than restaurants with fewer outlets, and training was not associated with lower numbers of violations from restaurants with many outlets. The value of having certified personnel was only observed in independent restaurants and those with few branches. This information may be useful in indicating where food safety problems are most likely to occur. Furthermore, we recommend that those characteristics of institutional and chain restaurants that result in fewer violations should be identified in future research, and efforts made to apply this knowledge at the level of individual restaurants.

Association of food-hygiene practices and diarrhea prevalence among Indonesian young children from low socioeconomic urban areas  

PubMed Central

Background Information on the part that poor food-hygiene practices play a role in the development of diarrhea in low socioeconomic urban communities is lacking. This study was therefore aimed at assessing the contribution of food-hygiene practice to the prevalence of diarrhea among Indonesian children. Methods A cross-sectional study was conducted among 274 randomly selected children aged 12–59 months in selected low socioeconomic urban areas of East Jakarta. The prevalence of diarrhea was assessed from 7-day records on frequency and consistency of the child’s defecation pattern. Food-hygiene practices including mother’s and child’s hand washing, food preparation, cleanliness of utensils, water source and safe drinking water, habits of buying cooked food, child’s bottle feeding hygiene, and housing and environmental condition were collected through home visit interviews and observations by fieldworkers. Thirty-six practices were scored and classified into poor (median and below) and better (above median) food-hygiene practices. Nutritional status of children, defined anthropometrically, was measured through height and weight. Results Among the individual food-hygiene practices, children living in a house with less dirty sewage had a significantly lower diarrhea prevalence compared to those who did not [adjusted odds ratio (OR) 0.16, 95% confidence interval (CI)?=?0.03-0.73].

Handwashing before Food Preparation and Child Feeding: A Missed Opportunity for Hygiene Promotion  

PubMed Central

Enteric diseases are often caused by poor hygiene and can contribute to stunting. From 50 randomly selected villages in Bangladesh, we collected quantitative and qualitative data on handwashing linked to child feeding to integrate handwashing promotion into a young child complementary feeding program. Most participants stated that the community knew the importance of handwashing with soap before food preparation and feeding a child, but had not developed the habit. We observed no handwashing with soap at these key times; sometimes hands were rinsed with water only. Most participants cited the unavailability of soap and water near the cooking place as a barrier to handwashing before food preparation. Most caregivers ranked nurturing messages as the best motivator to encourage handwashing with soap. An integrated intervention should include having soap and water available near the food preparation area and should use nurturing themes to encourage habitual handwashing with soap. PMID:24080638

[Food Security in Europe: comparison between the "Hygiene Package" and the British Retail Consortium (BRC) & International Food Standard (IFS) protocols].  


The birth of Hygiene Package and of the Reg. CE no 2073/2005 in the food production field signalled a change in Italy. This process started in Italy in 1997 with the legislative decree no 155 on Self-control but in reality, it was implemented in the UK in 1990 with the promulgation of the Food Safety Act. This legal act was influenced by some basic rules corresponding to the application of HACCP standards. Since 1990 the British chains of distribution (Retailers) have involved all aspects of the food line in this type of responsibility. Due to this growing awareness for a need for greater regulation, a protocol, edited by British Retail Consortium was created in 1998. This protocol acted as a "stamp" of approval for food products and it is now known as the BRC Global Food Standard. In July 2008, this protocol became effective in its fifth version. After the birth of BRC, also French and German Retailers have established a standard practically equivalent and perhaps more pertinent to safety food, that is International Food Standard (IFS). The new approach is specific to the food field and strictly applies criteria which will ensure "safety, quality and legality" of food products, similarly to ISO 22000:2005 (mainly based on BRC & IFS past experiences). New standards aim to create a sort of green list with fully "proper and fit" Suppliers only, because of comprehensible exigencies of Retailers. It is expected, as we have shown, that Auditor authorities who are responsible for ensuring that inspections are now carried out like the Hygiene Package, will find these new standards useful. The advantages of streamlining this system is that it will allow enterprises to diligently enforce food safety practices without fear of upset or legal consequence, to improve the quality (HACCP) of management & traceability system; to restrict wastes, reprocessing and withdrawal of products. However some discordances about the interpretation of certain sub-field norms (e.g., water management) are evident and should be carefully discussed once more. PMID:19798915

Hygienic food handling behaviors: attempting to bridge the intention-behavior gap using aspects from temporal self-regulation theory.  


An estimated 25% of the populations of both the United States and Australia suffer from foodborne illness every year, generally as a result of incorrect food handling practices. The aim of the current study was to determine through the application of the theory of planned behavior what motivates these behaviors and to supplement the model with two aspects of temporal self-regulation theory--behavioral prepotency and executive function--in an attempt to bridge the "intention-behavior gap." A prospective 1-week design was utilized to investigate the prediction of food hygiene using the theory of planned behavior with the additional variables of behavioral prepotency and executive function. One hundred forty-nine undergraduate psychology students completed two neurocognitive executive function tasks and a self-report questionnaire assessing theory of planned behavior variables, behavioral prepotency, and intentions to perform hygienic food handling behaviors. A week later, behavior was assessed via a follow-up self-report questionnaire. It was found that subjective norm and perceived behavioral control predicted intentions and intentions predicted behavior. However, behavioral prepotency was found to be the strongest predictor of behavior, over and above intentions, suggesting that food hygiene behavior is habitual. Neither executive function measure of self-regulation predicted any additional variance. These results provide support for the utility of the theory of planned behavior in this health domain, but the augmentation of the theory with two aspects of temporal self-regulation theory was only partially successful.

[Evaluation of the presence of hygienic and sanitary indicator microorganisms in food served in public schools in Porto Alegre, Brazil].  


The objective of this study was to evaluate the presence of hygienic and sanitary indicator microorganisms in samples of food served in public schools in Porto Alegre. All the food served in the meal of the session visited was analyzed for Escherichia coli, coagulase-positive Staphylococcus, Salmonella sp. and Shigella sp. Of the total of 196 food products analyzed in 120 schools, 4 contained and Escherichia coli score above the permitted level, and 2 contained coagulase-positive Staphylococcus. Neither Shigella nor Salmonella genus were detected. In the majority of schools studied, it was found that food was of an adequate hygienic-sanitary standard. However, only municipal schools had the supervision of a technician responsible for school food. In the state schools, 60% had never been visited by a nutritionist and in these schools several procedures failed to comply with legal requirements. In most of the schools studied, the food served to students was within adequate standards, though the problems detected revealed the need for the implementation of Best Practices in the school environment.

Microbiological quality of open ready-to-eat salad vegetables: effectiveness of food hygiene training of management.  


During September and October 2001, a microbiological study of open, ready-to-eat, prepared salad vegetables from catering or retail premises was undertaken to determine their microbiological quality. The study focused on those salad vegetables that were unwrapped and handled either by staff or customers in the premises where the sample was taken. Examination of salad vegetables from food service areas and customer self-service bars revealed that most (97%; 2,862 of 2,950) were of satisfactory or acceptable microbiological quality, 3% (87) were of unsatisfactory microbiological quality because of Escherichia coli levels in the range of 10(2) to 10(5) colony-forming units per gram. One (<1%) sample was of unacceptable microbiological quality because of the presence of Listeria monocytogenes at 840 colony-forming units per gram. The pathogens E. coli O157, Campylobacter spp., and salmonellas were not detected in any of the samples examined. The display area for most food service and preparation areas (95%) and self-service salad bars (98%) that were visited was judged to be visibly clean by the sampling officer. Most self-service bars (87%) were regularly supervised or inspected by staff during opening hours, and designated serving utensils were used in most salad bars (92%) but in only a minority of food service areas (35%). A hazard analysis system was in place in most (80%) premises, and in 61%, it was documented. Most (90%) managers had received food hygiene training. A direct relationship was shown between increased confidence in the food business management and the presence of food safety procedures and the training of management in food hygiene. PMID:14503709

An outbreak of Norwalk-like viral gastroenteritis in a frequently penalized food service operation: a case for mandatory training of food handlers in safety and hygiene.  


In 1999, in Toledo, Ohio, an outbreak of gastroenteritis occurred among people who had attended a Christmas dinner banquet and had eaten food prepared by a local caterer. Overall, 93 of the 137 attendees (67.9 percent) reported illness. Eight sought medical care, and one was hospitalized. Case-control studies revealed that the illness was associated with eating tossed salad (odds ratio [OR] = 2.5, 95 percent confidence interval [CI] = 1.02-6.26). Eleven of 12 stool specimens that were taken from ill people tested positive for a Norwalk-like virus (NLV) but were negative for E. coli O157:H7, Salmonella, and Shigella. The primary source of the outbreak was not determined, but an infected food handler may have played a role in the transmission of the virus. The catering facility had been cited frequently for food safety and hygiene violations. None of the personnel or food handlers at this facility had been appropriately trained in safe food-handling practices, nor had the personnel at another local caterer that had prepared food items suspected of causing a multistate outbreak of NLVs. In Toledo, food service operations with trained personnel/food handlers received better inspection reports than food service operations without trained personnel and were less likely to contribute to foodborne outbreaks. Training of personnel and food handlers may be important for preventing outbreaks. PMID:11764683

[Jean-Jacques Rosseau the vitalist. The moralization of medical hygiene between diet and ethical food].  


The historiographical prejudice that sees in Jean-Jacques Rousseau an implacable opponent of scientific knowledge has long prevented an objective evaluation of the important influence that medical thought exerted over his philosophy. The aim of this paper is to show not only Rousseau's familiarity with the most important expressions of eighteenth-century medical literature, but also his willingness to incorporate some medical suggestions in his philosophical and literary production. In the first part of this article, I try to show how Rousseau's sensibility theory presupposes precise medical ideals, related to Montpellier School of vitalism. In the second part, I stress how Rousseau's philosophy of alimentation (which has clear anthropological and political implications) can be regarded as a genuine application of an ambition typical of vitalism: to use medical hygiene, also and above all, for moral purpose.

Synthesis of nonionic-anionic colloidal systems based on alkaline and ammonium ?-nonylphenol polyethyleneoxy (n?=?3-20) propionates/dodecylbenzenesulfonates with prospects for food hygiene  

PubMed Central

Background The main objective of this work was to obtain a binary system of surface-active components (nonionic soap – alkaline and/or ammonium dodecylbenzenesulfonate) with potential competences in food hygiene, by accessing a scheme of classical reactions (cyanoethylation, total acid hydrolysis and stoichiometric neutralization with inorganic alkaline and/or organic ammonium bases) adapted to heterogeneously polyethoxylated nonylphenols (n?=?3-20). In the processing system mentioned, dodecylbenzenesulfonic acid, initially the acid catalyst for the exhaustive hydrolysis of ?-nonylphenolpolyethyleneoxy (n?=?3-20) propionitriles, becomes together with the nonionic soap formed the second surface-active component of the binary system. Results In the reaction scheme adopted the influence of the main operating (duration, temperature, molar ratio of reagents) and structural parameters (degree of oligomerization of the polyoxyethylene chain) on the processing yields for the synthetic steps was followed. The favorable role of the polyoxyethylene chain size is remarked, through its specific conformation and its alkaline cations sequestration competences on the yields of cyanoethylation, but also the beneficial influence of phase-transfer catalysts in the total acid hydrolysis step. The chemical stability of dodecylbenzenesulfonic acid (DBSH) at the temperature and strongly acidic pH of the reaction environment is confirmed. The controlled change of the amount of DBSH in the final binary system will later confer it potential colloidal competences in food hygiene receipts. Conclusions The preliminary synthetic tests performed confirmed the prospect of obtaining a broad range of useful colloidal competences in various food hygiene scenarios. PMID:22958389



Outbreaks where food workers have been implicated in the spread of foodborne disease. Part 11. Use of antiseptics and sanitizers in community settings and issues of hand hygiene compliance in health care and food industries.  


Hand washing with soap is a practice that has long been recognized as a major barrier to the spread of disease in food production, preparation, and service and in health care settings, including hospitals, child care centers, and elder care facilities. Many of these settings present multiple opportunities for spread of pathogens within at-risk populations, and extra vigilance must be applied. Unfortunately, hand hygiene is not always carried out effectively, and both enteric and respiratory diseases are easily spread in these environments. Where water is limited or frequent hand hygiene is required on a daily basis, such as for many patients in hospitals and astronauts in space travel, instant sanitizers or sanitary wipes are thought to be an effective way of preventing contamination and spread of organisms among coworkers and others. Most concerns regarding compliance are associated with the health care field, but the food industry also must be considered. Specific reasons for not washing hands at appropriate times are laziness, time pressure, inadequate facilities and supplies, lack of accountability, and lack of involvement by companies, managers, and workers in supporting proper hand washing. To facilitate improvements in hand hygiene, measurement of compliant and noncompliant actions is necessary before implementing any procedural changes. Training alone is not sufficient for long-lasting improvement. Multiactivity strategies also must include modification of the organization culture to encourage safe hygienic practices, motivation of employees willing to use peer pressure on noncompliant coworkers, a reward and/or penalty system, and an operational design that facilitates regular hand hygiene.

Development of microbiological field methodology for water and food-chain hygiene analysis of Campylobacter spp. and Yersinia spp. in Burkina Faso, West Africa.  


Field-adaptable research methods for identifying Campylobacter sp., Yersinia sp. and other pathogenic and indicator bacteria were designed in Finland and tested in Burkina Faso. Several bacterial groups were also validated from artificially contaminated samples. Campylobacter strains were cultivated using an innovative gas generation system: The 'Portable Microbe Enrichment Unit' (PMEU) which provides microaerobic gas flow into the enrichment broth. This enhanced cultivation system produced rapid growth of several isolates of campylobacteria from water and chicken samples. The latter were obtained from local marketplace samples. No yersinias were found in the field studies, whereas they were readily recovered from the spiked samples, as well as Salmonella sp. and Escherichia coli strains. The PMEU method turned out to be reliable for monitoring of water and food hygiene in remote locations. PMID:25156815

A training course on food hygiene for butchers: measuring its effectiveness through microbiological analysis and the use of an inspection checklist.  


The effectiveness of food hygiene training for a group of retail butchers was evaluated with the aim of verifying whether the butchers modified their behavior in the light of knowledge gained and whether their acquired knowledge or behavior change was sustained over a period of time. Microbiological analysis (enumeration of mesophilic and coliform bacteria and Escherichia coli) of a raw semiprocessed product (stuffed rolled beef) was conducted, and an inspection checklist was issued before the training course (T0). Initial results were later compared with results obtained 1 month (T1) and 6 months (T6) after the training. The checklist comprised 89 items classified into five categories: A, approved suppliers and product reception; B, storage conditions and temperature control; C, flow process, food handling procedures, and conditions of the window display unit; D, facility design and proper cleaning and sanitizing of equipment, utensils, and work surfaces; and E, pest control system, water supply control, and garbage disposal. The inspection results were recorded as "yes" or "no" for each item. Compliance with food safety procedures was recorded as the percentage of "yes" answers. The bacterial counts were significantly higher at T0. At T6, there was no significant increase in bacterial counts. There was a significant improvement in food safety practices at T1 and T6 compared with T0 for all categories. When comparing T0 and T1, the largest increases in the compliance scores were seen within categories C and D. No significant decrease in scores for compliance with food safety practices was observed at T6. Supervision and refresher activities may be necessary to maintain behavioral changes for a longer period of time. PMID:16300085

[Hygiene practices for patients with HIV/AIDS].  


The objective of this study was to analyze the scientific production on health interventions related to hygiene for adults with HIV/AIDS. An integrative literature review was performed using six databases in June 2013. The descriptors AIDS and Hygiene were used, in Portuguese, English or Spanish. A total of 682 articles were found and 16 were selected. Personal hygiene practices were identified, such as hand washing, showers, tooth brushing and quitting smoking. Food hygiene practices involved washing food and kitchen utensils, using treated water, conserving and cooking food. Environmental hygiene took into account raising domestic animals, control of disease vectors, household cleanliness, waste disposal and basic sanitation. In conclusion, these specific hygiene interventions can be applied to the general population and, especially, to people with HIV/AIDS, due to immunosuppression. PMID:25508776

[Parmentier hygiene and public health].  


The legend about Parmentier is quite reductive when it limits his activity to the promotion of potato. This military pharmacist intended mainly to make science serve human being, whatever could be his various activities. Actor of the foundation of food chemistry, reorganizer of military pharmacy, he has always been highly concerned with hygiene and public health. He then studied the quality of water, particularly in the case of river Seine, or the purity of air, especially in hospitals. The affair of Dunkerque exhumations or that of cesspools, or the utilisation of human excrements in agriculture were parts of the occurrences for which he had the opportunity to find a scientific approach allowing to solve the difficult questions that were asked to him, for the best benefit of public health. The exhaustive study he published in "Bulletin de pharmacie" for the conservation of meat shows that he did not ignore anything about freezing of food in order to preserve it. It is necessary not to forget the important role he played, as soon as he were informed of Jenner's discovery, for the diffusion of vaccination in France. It is simply astounding to observe how modern were the questions he solved and how intense was his spirit of dedication to the public good, when exerting his functions in "Comité de Salubrité de la Seine" or "Conseil de Santé des Armées", as well as outside these prestigious institutions.

Improving oral hygiene for patients.  


Systematic reviews and patient safety initiatives recommend that oral hygiene should be part of routine patient care. However, evidence suggests it is often neglected in hospitals and care homes. Research recommends encouraging beliefs that support oral hygiene, and teaching nurses appropriate skills, as necessary prerequisites to implementing best practice in hospital wards. This article describes a pilot study of an educational workshop on oral hygiene. Results from the pilot study suggest that this workshop is a feasible intervention for a service-wide trial. The literature suggests that other interventions are required to complement this approach if nurses are to make oral hygiene a priority in daily patient care. PMID:25563127

Regulations on Meat Hygiene in the USA  

NASA Astrophysics Data System (ADS)

Regulations on meat hygiene in the United States of America (US) stem from the Federal Meat Inspection Act (FMIA, 21 USC §§ 601 et. seq.), promulgated in 1906, that gives the US Secretary of Agriculture (the Secretary) the power to oversee the conversion of livestock into meat products. The FMIA is reviewed herein to provide a background for discussion on how the US Department of Agriculture (USDA) and its departments, particularly the Food Safety and Inspection Service (FSIS), control and regulate the meat industry. This chapter discusses regulations that pertain to meat, herein meant to mean beef, veal, and pork, and does not specifically address poultry, although the regulations for poultry slaughter and processing are in many ways similar to those for meat and meat food products.

Industrial Hygiene Issues  

NASA Technical Reports Server (NTRS)

This breakout session is a traditional conference instrument used by the NASA industrial hygiene personnel as a method to convene personnel across the Agency with common interests. This particular session focused on two key topics, training systems and automation of industrial hygiene data. During the FY 98 NASA Occupational Health Benchmarking study, the training system under development by the U.S. Environmental Protection Agency (EPA) was deemed to represent a "best business practice." The EPA has invested extensively in the development of computer based training covering a broad range of safety, health and environmental topics. Currently, five compact disks have been developed covering the topics listed: Safety, Health and Environmental Management Training for Field Inspection Activities; EPA Basic Radiation Training Safety Course; The OSHA 600 Collateral Duty Safety and Health Course; and Key program topics in environmental compliance, health and safety. Mr. Chris Johnson presented an overview of the EPA compact disk-based training system and answered questions on its deployment and use across the EPA. This training system has also recently been broadly distributed across other Federal Agencies. The EPA training system is considered "public domain" and, as such, is available to NASA at no cost in its current form. Copies of the five CD set of training programs were distributed to each NASA Center represented in the breakout session. Mr. Brisbin requested that each NASA Center review the training materials and determine whether there is interest in using the materials as it is or requesting that EPA tailor the training modules to suit NASA's training program needs. The Safety, Health and Medical Services organization at Ames Research Center has completed automation of several key program areas. Mr. Patrick Hogan, Safety Program Manager for Ames Research Center, presented a demonstration of the automated systems, which are described by the following: (1) Safety, Health and Environmental Training. This system includes an assessment of training needs for every NASA Center organization, course descriptions, schedules and automated course scheduling, and presentation of training program metrics; (2) Safety and Health Inspection Information. This system documents the findings from each facility inspection, tracks abatement status on those findings and presents metrics on each department for senior management review; (3) Safety Performance Evaluation Profile. The survey system used by NASA to evaluate employee and supervisory perceptions of safety programs is automated in this system; and (4) Documentation Tracking System. Electronic archive and retrieval of all correspondence and technical reports generated by the Safety, Health and Medical Services Office are provided by this system.

[Hygiene practices in a street market in the city of Salvador, Bahia State].  


The main objective of this research is to understand the meaning of the practices concerning food hygiene in a street market in Salvador, the capital of Bahia State in Brazil. The ethnographic study presents two main categories for symbolic production related to hygiene practices: cleanliness as order and dirtiness as disorder. These cultural codes make correspondence with the studies of Mary Douglas and Nobert Elias. The codes present particularities to decode everyday life, in which concept and hygiene practices are aspects normalized, in daily activity, for persons who share the space of street market: vendors, consumers, street cleaners and official inspectors. The techno-scientific knowledge and sanitary legislation are strange to the symbolic system of street market vendors. The laws are ineffective and their influence is of little importance in the creation of hygiene practices. Official inspectors' attitudes are coercive and punitive and do not take into account any cultural values when enforcing new hygiene practices. PMID:20640322

[Preoperational study for the improvement of hygiene conditions in long-term care facilities].  


Hygiene is becoming more and more important in long-term care facilities. Long-term care facilities are subject to monitoring by the Public Health Service (PHS) and other authorities. For the PHS in Bavaria the Bavarian Health and Food Safety Authority (Landesamt für Gesundheit und Lebensmittelsicherheit, LGL) published a hygiene monitoring concept and there exists an inspection guide developed by a specialist department for nursing homes and institutions for the handicapped (Fachstelle für Pflege und Behinderteneinrichtungen, FQA). Because inspections are performed in multiprofessional teams, it makes sense to use a coordinated inspection catalog. The aim was to integrate hygienic requirements specified in the Bavarian guidelines for hygiene by the LGL into the inspection guide published by the FQA to obtain a quality assured surveillance. The involved parties were questioned about the inspection guide and their hygiene management and then the hygiene criteria of the LGL were implemented into the inspection guide. Questions dealing with hygiene requirements concerning intensive care, management of multidrug resistant bacteria and interviews with the person responsible for infection control in the facility itself were developed for the first time and were integrated into the inspection guide. The revised inspection guide was tested for its applicability. With the revised inspection guide there now exists a tool which allows not only comprehensive inspections of the facilities including hygiene issues but also a good cooperation of the various parties involved. There are many actions which have to be conveyed into the future, especially programs to train staff to apply the inspection guide and to enhance the ability of all participants to act in cooperation. The guide will also allow the facilities to cooperate more easily and more closely, as the guide takes the respective problems and challenges of the different facilities into consideration. Additionally the development of legal guidelines regarding hygiene can support general healthcare of residents. PMID:25367175

Personal and Household Hygiene, Environmental Contamination, and Health in Undergraduate Residence Halls in New York City, 2011  

PubMed Central

Background While several studies have documented the importance of hand washing in the university setting, the added role of environmental hygiene remains poorly understood. The purpose of this study was to characterize the personal and environmental hygiene habits of college students, define the determinants of hygiene in this population, and assess the relationship between reported hygiene behaviors, environmental contamination, and health status. Methods 501 undergraduate students completed a previously validated survey assessing baseline demographics, hygiene habits, determinants of hygiene, and health status. Sixty survey respondents had microbiological samples taken from eight standardized surfaces in their dormitory environment. Bacterial contamination was assessed using standard quantitative bacterial culture techniques. Additional culturing for coagulase-positive Staphylococcus and coliforms was performed using selective agar. Results While the vast majority of study participants (n?=?461, 92%) believed that hand washing was important for infection prevention, there was a large amount of variation in reported personal hygiene practices. More women than men reported consistent hand washing before preparing food (p?=?.002) and after using the toilet (p?=?.001). Environmental hygiene showed similar variability although 73.3% (n?=?367) of subjects reported dormitory cleaning at least once per month. Contamination of certain surfaces was common, with at least one third of all bookshelves, desks, refrigerator handles, toilet handles, and bathroom door handles positive for >10 CFU of bacteria per 4 cm2 area. Coagulase-positive Staphylococcus was detected in three participants' rooms (5%) and coliforms were present in six students' rooms (10%). Surface contamination with any bacteria did not vary by frequency of cleaning or frequency of illness (p>.05). Conclusions Our results suggest that surface contamination, while prevalent, is unrelated to reported hygiene or health in the university setting. Further research into environmental reservoirs of infectious diseases may delineate whether surface decontamination is an effective target of hygiene interventions in this population. PMID:24312303

ISS Hygiene Activities - Issues and Resolutions  

NASA Technical Reports Server (NTRS)

Hygiene is something that is usually taken for granted by those of us on the Earth. The ability to perform hygiene satisfactorily during long duration space flight is crucial for the crew's ability to function. Besides preserving the basic health of the crew, crew members have expressed that the ability to clean up on-orbit is vital for mental health. Providing this functionality involves more than supplying hygiene items such as soap and toothpaste. On the International Space Station (ISS), the details on where and how to perform hygiene were left to the crew discretion for the first seventeen increments. Without clear guidance, the methods implemented on-orbit have resulted in some unintended consequences to the ISS environment. This paper will outline the issues encountered regarding hygiene activities on-board the ISS, and the lessons that have been learned in addressing those issues. Additionally, the paper will address the resolutions that have been put into place to protect the ISS environment while providing the crew sufficient means to perform hygiene.

Back to basics: hand hygiene and isolation  

PubMed Central

Purpose of review Hand hygiene and isolation are basic, but very effective, means of preventing the spread of pathogens in healthcare. Although the principle may be straightforward, this review highlights some of the controversies regarding the implementation and efficacy of these interventions. Recent findings Hand hygiene compliance is an accepted measure of quality and safety in many countries. The evidence for the efficacy of hand hygiene in directly reducing rates of hospital-acquired infections has strengthened in recent years, particularly in terms of reduced rates of staphylococcal sepsis. Defining the key components of effective implementation strategies and the ideal method(s) of assessing hand hygiene compliance are dependent on a range of factors associated with the healthcare system. Although patient isolation continues to be an important strategy, particularly in outbreaks, it also has some limitations and can be associated with negative effects. Recent detailed molecular epidemiology studies of key healthcare-acquired pathogens have questioned the true efficacy of isolation, alone as an effective method for the routine prevention of disease transmission. Summary Hand hygiene and isolation are key components of basic infection control. Recent insights into the benefits, limitations and even adverse effects of these interventions are important for their optimal implementation. PMID:24945613

Hand Hygiene in Emergency Medical Services.  


Abstract Background. Hospital-acquired infections (HAIs) affect millions of patients annually (World Health Organization. Guidelines on Hand Hygiene in Healthcare. Geneva: WHO Press; 2009). Hand hygiene compliance of clinical staff has been identified by numerous studies as a major contributing factor to HAIs around the world. Infection control and hand hygiene in the prehospital environment can also contribute to patient harm and spread of infections. Emergency medical services (EMS) practitioners are not monitored as closely as hospital personnel in terms of hand hygiene training and compliance. Their ever-changing work environment is less favorable to traditional hospital-based aseptic techniques and education. Methods. This study aimed to determine the current state of hand hygiene practices among EMS providers and to provide recommendations for improving practices in the emergency health services environment. This study was a prospective, observational prevalence study and survey, conducted over a 2-month period. We selected participants from visits to three selected hospital emergency departments in the mid-Atlantic region. There were two data components to the study: a participant survey and hand swabs for pathogenic cultures. Results. This study recruited a total sample of 62 participants. Overall, the study revealed that a significant number of EMS providers (77%) have a heavy bacterial load on their hands after patient care. All levels of providers had a similar distribution of bacterial load. Survey results revealed that few providers perform hand hygiene before (34%) or in between patients (24%), as recommended by the Centers for Disease Control and Prevention guidelines. Conclusion. This study demonstrates that EMS providers are potential vectors of microorganisms if proper hand hygiene is not performed properly. Since EMS providers treat a variety of patients and operate in a variety of environments, providers may be exposed to potentially pathogenic organisms, serving as vectors for the exposure of their patients to these same organisms. Proper application of accepted standards for hand hygiene can help reduce the presence of microbes on provider hands and subsequent transmission to patients and the environment. PMID:25415186

New technologies to monitor healthcare worker hand hygiene.  


Compliance with hand hygiene is a good quality indicator for hospital patient safety programmes. Hand hygiene is a major infection control prevention intervention, but in many medical centres compliance rates are only c. 50%. Given the enormous number of hand hygiene opportunities in hospitals, direct observation to monitor compliance is very inefficient. However, technologies are emerging to obviate the need for direct observation. These new technologies for monitoring hand hygiene compliance are discussed in this article. PMID:24245809

Hand hygiene among health care workers.  


Healthcare-associated infections are an important cause of morbidity and mortality among hospitalized patients worldwide. Transmission of health care associated pathogens generally occurs via the contaminated hands of health care workers. Hand hygiene has long been considered one of the most important infection control measures to prevent health care-associated infections. For generations, hand washing with soap and water has been considered a measure of personal hygiene. As early as 1822, a French pharmacist demonstrated that solutions containing chlorides of lime or soda could eradicate the foul odor associated with human corpses and that such solutions could be used as disinfectants and antiseptics. This paper provides a comprehensive review of data regarding hand washing and hand antisepsis in healthcare settings. In addition, it provides specific recommendations to uphold improved hand-hygiene practices and reduce transmission of pathogenic microorganisms to patients and personnel in healthcare settings. This article also makes recommendations and suggests the significance of hand health hygiene in infection control. PMID:20427920

Public farms: hygiene and zoonotic agents.  


In three successive years, we visited petting farms (n=132), care farms (n=91), and farmyard campsites (n=84), respectively, and completed a standard questionnaire with the objective of determining the hygienic status of these farms and describing hygiene measures implemented to reduce the risk of transmission of zoonotic agents from the animals to humans. For at least 85% of the farms, the overall impression of hygiene was recorded as good. However, more attention must be paid to: informing visitors on hygiene and handwashing, provision of handwashing facilities, and a footwear cleaning facility. Examination of samples of freshly voided faeces resulted in the detection of Shiga toxin-producing Escherichia coli O157 and/or Salmonella spp. and/or Campylobacter spp. at almost two-thirds (64.9%) of the petting farms, and around half of the care farms (56.0%) and farmyard campsites (45.2%). These data reinforce the need for control measures for both public and private farms to reduce human exposure to livestock faeces and thus the risk of transmission of zoonotic diseases. Public awareness of the risk associated with handling animals or faecal material should be increased. PMID:17313696

[National Institute of Hygiene during the World War 1939-1944].  


The article presents history of the National Institute of Hygiene (PZH) in the period from September 1939 until the fall of Warsaw Uprising (1944). German occupation left unaltered activities, structure and Polish personnel of the Institute, enforcing commissoner board by professor Ernst Nauck, and subsequently--professor Robert Kudicke from Frankfurt. German production of vaccine against typhus exanthematous for German army was managed by German physician--Herman Wohlrab. National Institute of Hygiene was to be a place modelled on Institute for Tropical Diseases in Hamburg. Polish personnel was subject to military regime, however Feliks Przesmycki, PhD started underground production of vaccine against typhus exanthematous for Polish citizens, which was distributed to prisons (Pawiak Prison) and ghetto. Hospital personnel in Warsaw was also vaccinated. Underground studies programme, including editing handbooks, was set up for the students of closed Microbiology Faculty of Warsaw University, and other wartime conspiracy actions were taken. Personnel of National Institute of Hygiene (PZH) protected research equipment and supplies from war plundering, and supported Polish civilians by e.g. reporting about harmfulness of low-quality and polluted food for the Polish, which Germans supplied market with. During Warsaw Uprising Personnel helped the injured and protected the premises of National Institute of Hygiene (PZH) from burning down; mobile army surgical hospital and pharmacy for the participans of Warsaw Uprising functioned within PZH.

Improving adherence to hand hygiene practice: a multidisciplinary approach.  

PubMed Central

Hand hygiene prevents cross-infection in hospitals, but health-care workers' adherence to guidelines is poor. Easy, timely access to both hand hygiene and skin protection is necessary for satisfactory hand hygiene behavior. Alcohol- based hand rubs may be better than traditional handwashing as they require less time, act faster, are less irritating, and contribute to sustained improvement in compliance associated with decreased infection rates. This article reviews barriers to appropriate hand hygiene and risk factors for noncompliance and proposes strategies for promoting hand hygiene. PMID:11294714

Hand hygiene posters: selling the message.  


This literature review was undertaken to determine the established theory and research that might be utilized to inform the construction of persuasive messages on hand hygiene posters. It discusses the principles of message framing and the use of fear appeals. Current theory suggests that the most effective messages for health promotion behaviours should be framed in terms of gains rather than losses for the individual. However, as clinical hand hygiene is largely for the benefit of others (i.e. patients), messages should also invoke a sense of personal responsibility and appeal to altruistic behaviour. The use of repeated minimal fear appeals have their place. Posters that simply convey training messages are not effective persuaders. PMID:15702513

American Social Hygiene Posters, 1910 - 1970  

NSDL National Science Digital Library

This fascinating collection of social hygiene posters (designed to inculcate certain social practices regarding hygiene, friendship, prostitution, and mental health) is culled from the fine holdings of the Social Welfare History Archives at the University of Minnesota Libraries. Interestingly enough, the Archives were established in 1964 by the historian Clarke Chambers, who in his own work on voluntary associations discovered that most manuscript repositories had collected very few social welfare records. Visitors will appreciate the online search engine which features options such as a time period search, a keyword search, and the opportunity to search by the subject or theme of each poster. Each record contains an image of the original poster, information about the poster's provenance, its creation date, and the organization responsible for creating the poster. For those interested in the social history of the United States during this period, this small collection will be quite appealing.

[Infrasound: body's effects and hygienic regulation].  


The paper analyzes and sums up technically originated infrasound (IS) hygienic problems. Trends for an increase in its role as an unfavourable factor of the industrial, transport, and residential environments are established. Comprehensive physiological, hygienic, and experimental studies revealed the pathogenetic features of IS. Involvement of the limbicoreticular complex, hypothalamus, and other subcortical structures into responses to higher factor levels on human beings stipulates a sharply prominent pathological discomfort as a manifestation of the infrasonic diencephalic hypothalamic syndrome with sensorisomatic and autonomic visceral symptoms. A conceptual pathogenetic model of IS exposure has been worked out. Main subjective and objective signs of and criteria for IS exposure have been defined, its ranking by human risk areas is given with the influencing factor parameters borne in mind. The biometry of biological effects on exposure to IS at 4 and Hz and at 130 dB and their changes in the vestibular and acoustic analyzers, as well as in the neurohumoral regulation system and other homeostatic parameters has revealed the priority of the whole body's responses.

[Postural hygiene and ergonomic advices for low back pain: rethinking our practice].  


In recent years, scientific understanding of low back pain has increased considerably, sometimes shoving concepts thought to be unshakable. If we consider postural hygiene,whose techniques were conceptualized in the 70's and are still widely used, not only some axioms were not confirmed but some evidences suggest that it may sometimes have deleterious effects. After reviewing these elements it appears that there is no simple formula applicable to all patients with low back pain. Instead we offer food for thought so that every therapist can adapt his practice on an individual basis. PMID:22455153

Teaching minority children hygiene: investigating hygiene education in kindergartens and homes of ethnic minority children in northern Vietnam.  


Objectives. Ethnic minority children in Vietnam experience high levels of hygiene- and sanitation-related diseases. Improving hygiene for minority children is therefore vital for improving child health. The study objective was to investigate how kindergarten and home environments influence the learning of hygiene of pre-school ethnic minority children in rural Vietnam. Design. Eight months of ethnographic field studies were conducted among four ethnic minority groups living in highland and lowland communities in northern Vietnam. Data included participant observation in four kindergartens and 20 homes of pre-school children, together with 67 semi-structured interviews with caregivers and five kindergarten staff. Thematic analysis was applied and concepts of social learning provided inputs to the analysis. Findings. This study showed that poor living conditions with lack of basic sanitation infrastructures were important barriers for the implementation of safe home child hygiene. Furthermore, the everyday life of highland villages, with parents working away from the households resulted in little daily adult supervision of safe child hygiene practices. While kindergartens were identified as potentially important institutions for improving child hygiene education, essential and well-functioning hygiene infrastructures were lacking. Also, hygiene teaching relied on theoretical and non-practice-based learning styles, which did not facilitate hygiene behaviour change in small children. Minority children were further disadvantaged as teaching was only provided in non-minority language. Conclusions. Kindergartens can be important institutions for the promotion of safe hygiene practices among children, but they must invest in the maintenance of hygiene and sanitation infrastructures and adopt a strong practice-based teaching approach in daily work and in teacher's education. To support highland minority children in particular, teaching styles must take local living conditions and caregiver structures into account and teach in local languages. Creating stronger links between home and institutional learning environments can be vital to support disadvantaged highland families in improving child health. PMID:24875851

Outcomes of dental hygiene baccalaureate degree education in Canada.  


There is little published literature about the outcomes of dental hygiene baccalaureate degree education, particularly in Canada. Since there are various dental hygiene entry-to-practice educational models in Canada, exploring baccalaureate dental hygiene education is becoming an increasingly important subject. The purpose of this study was to explore the personal outcomes and dental hygiene practice outcomes of dental hygiene degree-completion education in Canada from the perspectives of diploma dental hygienists who have continued their education to the bachelor's degree level. This study employed a qualitative phenomenological design, using a maximum variation purposeful sampling strategy. Data generation occurred with sixteen dental hygienists across Canada through individual semistructured interviews. Interviews were audiorecorded, transcribed verbatim, and coded for data analysis, involving pattern recognition and thematic development. Themes that emerged included changes in self-perception, values, and knowledge base. Changes in self-perception were reflected in a reported increase in self-confidence and perceived credibility. Changes in values included a greater appreciation for lifelong learning. Advancements in knowledge strengthened the development of specific abilities that ultimately influenced participants' dental hygiene practice. These abilities included an increased ability to think critically, to make evidence-based decisions, and to provide more comprehensive care. Participants also commented on having more career opportunities available to them outside of the private clinical practice setting. These results reveal important insights into the impact of earning a dental hygiene baccalaureate degree on oneself and one's dental hygiene practice. PMID:21368255

[Personal hygiene and cleanliness in an international comparison].  


The investigation was intended to analyse the attitude towards hygiene and cleanliness in the Federal Republic of Germany, France, and Spain. On the basis of a theoretical explanatory model and empirically gained qualitative raw data a standardized questionnaire was prepared; in a number of questions comparability with a study carried out in the Federal Republic of Germany in 1968 was ensured. In all countries the population was subjected to representative random tests (Federal Republic of Germany n = 1016; France n = 517; Spain n = 514). The paper presents a review of the hypothesis that quality and intensity of the cleanliness increases with (1) the extent of personal sensitivity to hygiene in the private, professional and public sphere, (2) with increasing physical sensibility, (3) the increase in our knowledge of hygiene and health, (4) with the increase in the personal behavioral standards for measures concerned with prevention, hygiene of the body, household, underwear and environment, (5) with the increasing weight given to hygiene and toilet during the process of development, and (6) with the extent of regular control of education in cleanliness based on established rules of behavior. The spheres of behavior investigated and mentioned below confirmed the validity of the hypothesis for (1) household hygiene (spring-cleaning, window cleaning, cleaning of the home: dusting, vacuum-cleaning, cleaning of the floor), (2) hygiene of the body (frequency of taking a shower, bathing, toothbrushing, intimate hygiene), (3) hygiene of the laundry (frequency of changing underclothes such as panties/underpants, brassieres, nightgowns/pyjamas, stockings/socks, linen, pillows, dish and kitchen towels). The following general findings were established: (1) In the Federal Republic of Germany the attitude towards hygiene and cleanliness has improved over the last 20 years. (2) The level of hygiene and cleanliness in France and Spain is significantly higher than in the FRG. (3) The use of regular and also strict parental controls of the child's attitude towards cleanliness, as well as the continuity and systematic pursuance of this hygiene-orientated education is far more spread in France and in Spain than in the Federal Republic of Germany. (4) Within the population of a country differences are attributable to the quality of the parental educational efforts, to the importance of sex-specific cleanliness and toilet standards, to the knowledge of or the prejudices against the interrelationship between hygiene, cleanliness and health, the degree of private, public and professional hygiene sensibility, and physical sensibility.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:2500808

Street foods in Accra, Ghana: how safe are they?  

PubMed Central

OBJECTIVE: To investigate the microbial quality of foods sold on streets of Accra and factors predisposing to their contamination. METHODS: Structured questionnaires were used to collect data from 117 street vendors on their vital statistics, personal hygiene, food hygiene and knowledge of foodborne illness. Standard methods were used for the enumeration, isolation, and identification of bacteria. FINDINGS: Most vendors were educated and exhibited good hygiene behaviour. Diarrhoea was defined as the passage of > or =3 stools per day) by 110 vendors (94.0%), but none associated diarrhoea with bloody stools; only 21 (17.9%) associated diarrhoea with germs. The surroundings of the vending sites were clean, but four sites (3.4%) were classified as very dirty. The cooking of food well in advance of consumption, exposure of food to flies, and working with food at ground level and by hand were likely risk factors for contamination. Examinations were made of 511 menu items, classified as breakfast/snack foods, main dishes, soups and sauces, and cold dishes. Mesophilic bacteria were detected in 356 foods (69.7%): 28 contained Bacillus cereus (5.5%), 163 contained Staphylococcus aureus (31.9%) and 172 contained Enterobacteriaceae (33.7%). The microbial quality of most of the foods was within the acceptable limits but samples of salads, macaroni, fufu, omo tuo and red pepper had unacceptable levels of contamination. Shigella sonnei and enteroaggregative Escherichia coli were isolated from macaroni, rice, and tomato stew, and Salmonella arizonae from light soup. CONCLUSION: Street foods can be sources of enteropathogens. Vendors should therefore receive education in food hygiene. Special attention should be given to the causes of diarrhoea, the transmission of diarrhoeal pathogens, the handling of equipment and cooked food, hand-washing practices and environmental hygiene.

[Food poisoning--importance of international perspective].  


It is important to obtain the information on food security in the countries other than Japan since more than 60 % of the food consumed come from these countries. Food security is now considered as a global issue. A global trend persuading us to provide safe food to humans is based on the concept of human security development associated with a sense of human mission to sustain one's life. Another global tendency pushing us to secure safety and hygiene of food is driven by the economic pressure coming from the rules in international trade established by Codex Committee under FAO/WHO. In contrast to these trends under globalization requesting safe and hygienic food, food habits based on tradition or religion are maintained locally in various parts of the world. These local habits include eating raw or improperly cooked foods, which may become a risk of being exposed to food poisoning pathogens. This issue may be adequately solved by a risk assessment approach based on the concept of appropriate level of protection (ALOP). Like or not, people in some local areas live in the unhygienic environment where they are unintentionally and frequently exposed to enteric pathogens or immunologically cross-reacting microorganisms through which they may acquire specific immunity to the pathogens and escape from infection by the pathogens. There are therefore many areas in the world where people understand the necessity to provide safe food at the international level (globalization) but actually consume food in varying hygienic conditions from area to area due in part to traditional food habits or living environments (localization); we call this situation as glocalization (global+local).

Autism, Asthma, Inflammation, and the Hygiene Hypothesis  

PubMed Central

Inflammation and the genes, molecules, and biological pathways that lead to inflammatory processes influence many important and disparate biological processes and disease states that are quite often not generally considered classical inflammatory or autoimmune disorders. These include development, reproduction, aging, tumor development and tumor rejection, cardiovascular pathologies, metabolic disorders, as well as neurological and psychiatric disorders. This paper compares parallel aspects of autism and inflammatory disorders with an emphasis on asthma. These comparisons include epidemiological, morphometric, molecular, and genetic aspects of both disease types, contributing to a hypothesis of autism in the context of the immune based hygiene hypothesis. This hypothesis is meant to address the apparent rise in the prevalence of autism in the population. PMID:17412520

Educational technology for millennial dental hygiene students: a survey of U.S. dental hygiene programs.  


A growing body of literature suggests that today's learners have changed and education must change as well since Millennial generation students expect technology to be used in their coursework. This study sought to determine what educational technology is being used in U.S. dental hygiene programs, what student and faculty perceptions are of the effectiveness of technology, and what barriers exist to implementing educational technology. A stratified random sample of 120 entry-level dental hygiene programs nationwide were invited to participate in a survey. Fourteen programs participated, yielding a pool of 415 potential individual participants; out of those, eighty-four student and thirty-eight faculty respondents were included in the analysis, a total of 122. Results were analyzed using descriptive statistics and a Mann-Whitney U test (p<0.05). Faculty and student respondents agreed on the effectiveness of educational technology in all areas except clickers and wikis. The faculty members tended to rate the effectiveness of educational technology higher than did the students. The greatest perceived barrier to implementing technology was technical difficulties. This study suggests that support services should be available to faculty and students to ensure successful implementation of technology. Dental hygiene educators have adopted many types of educational technology, but more data are needed to determine best practices. PMID:24882769

[The evolution and characteristics of social hygiene in modern Japan].  


The purpose of this paper is the clarification of the theory of social hygiene and its conception in modern society. The theory of social hygiene in modern society was mainly formed by the influence of social democracy and the social reform movement. Social hygiene in modern Japan was presented by Germany in the middle Meiji era and prevailed in the Taisho era. Yoshie Fukuhara, Gito Terouka and Teido Kunisaki developed the mainstream of the theory about social hygiene in modern Japan. The principle of social hygiene in Japan was that the target group of social hygienic activities (such as laborers, poor people, consumers of medical service and so on) should establish the idea of self-government and autonomy of their lives. Social supports to the target group were recognized as combining with the idea of self-government and autonomy of lives. Some of those activities influenced by the principle were performed. Particularly, the work of Tetsuo Hoshino was unique in showing the relation between health and human culture. The work has shown that human health is reflected in human cultural activities. Social hygiene was important to the foundation of introduction and evolution of the thoughts of public health, health culture and medical insurance in modern Japan. PMID:11639780

[Food hygiene aspects in the production of food fish in fishing].  


The development of the aerob-mesophilic bacteria on epidermis and peritoneum of 68 barbels was determined at 0, 4 and 8 hours after slaughtering. Therefore, one group of 34 animals was stored at 15.3 degrees C, an other equal one at 21.6 degrees C. A change in germ counts per cm2 could be seen in none of the groups during the first 4 hours. However, unrefrigerated carcasses showed an increase of bacteria up to 5-fold between the 4th and 8th hour, whereas in the refrigerated group no change occurred during that time, too. Rinsing the fish after slaughtering resulted in a decrease of the initial bacterial counts by up to 65.4% and so in significantly lower germ loads at the end of the storage time. These results were confirmed by contaminating 24 rainbow trout with Salmonella Infantis artificially. The frequency of detection did not change in refrigerated fish over 8 hours, while nearly doubling in unrefrigerated ones. Moreover, it could be shown that a Salmonella-concentration of only 30 CFU per 100 ml water was sufficient for contaminating fish in detectable grades. The study leads to the conclusion that the storage of instantly slaughtered fish in a common thermobox with freezing elements is suited for preserving its microbiological status for at least 8 hours. The caging of living fish after capture, which must be regarded critically under the aspect of treating animals in a humane way, seems therefore unnecessary. PMID:9157842

The germless theory of allergic disease: revisiting the hygiene hypothesis  

Microsoft Academic Search

Rising rates of allergic disease accompany the healthier benefits of a contemporary westernized lifestyle, such as low infant mortality. It is likely that these twinned phenomena are causally related. The hygiene hypothesis states that allergy and increased longevity are both consequences of reducing infectious stressors during early childhood. Mechanistic explanations for the hygiene hypothesis have typically invoked the T-helper-type 1\\/2

[Trends in the joint work of the National Center for Hygiene and the epidemiological hygiene inspectorates in the field of communal hygiene].  


Based on cardinal problems of medical prevention, the author formulates priority lines of action for the country's health structures in the field of community health, emphasizing areas for interaction between the National Center of Hygiene and Hygiene-and-Epidemiology Inspectorates across the country. According to the author, priority problems necessitating collaborative efforts between the National Center of Hygiene and HEIs throughout the country should be focused on the following areas: updating sanitary legislation; environmental monitoring, including community and territorial planning; health risk assessment; development of an efficient health-information system concerning environment and health; manpower training; and ecologic education of the public. Collaboration also needs to cover joint implementation of projects at international collaboration level along the lines of the World Health Organization, the PHARE programs, etc. The priorities referred to also reflect the conception of medical prevention functions in the area of community health.

The impact of home-prepared diets and home oral hygiene on oral health in cats and dogs.  


Many factors influence the oral health status of cats and dogs. The present study aimed to elucidate the influence of feeding home-prepared (HP) food v. commercial pet food on oral health parameters in these animals and to investigate the effect of home oral hygiene on oral health. The study surveyed 17,184 dogs and 6371 cats visiting over 700 Polish veterinary surgeries in 2006-7 during a Pet Smile activity organised by the Polish Small Animal Veterinary Association. All animals underwent conscious examinations to assess dental deposits, size of mandibular lymph nodes and gingival health. An oral health index (OHI) ranging from 0 to 8 was calculated for each animal by combining examination scores, where 0 indicates good oral health and 8 indicates poorest oral health. Information was collected on age, diet and home oral hygiene regimens. There was a significant effect of diet on the OHI (P < 0.001) whereby feeding the HP diet increased the probability of an oral health problem in both cats and dogs. There was a significant beneficial effect of feeding only commercial pet food compared with the HP diet when at least part of the diet was composed of dry pet food. Daily tooth brushing or the offering of daily dental treats were both effective in significantly reducing the OHI in both cats and dogs compared with those receiving sporadic or no home oral hygiene. Feeding only a dry diet was beneficial for oral health in cats and dogs. Tooth brushing and the offering of dental treats were very effective in maintaining oral health, provided they were practised daily. PMID:22005407

'My five moments for hand hygiene': a user-centred design approach to understand, train, monitor and report hand hygiene.  


Hand hygiene is a core element of patient safety for the prevention of healthcare-associated infections and the spread of antimicrobial resistance. Its promotion represents a challenge that requires a multi-modal strategy using a clear, robust and simple conceptual framework. The World Health Organization First Global Patient Safety Challenge 'Clean Care is Safer Care' has expanded educational and promotional tools developed initially for the Swiss national hand hygiene campaign for worldwide use. Development methodology involved a user-centred design approach incorporating strategies of human factors engineering, cognitive behaviour science and elements of social marketing, followed by an iterative prototype test phase within the target population. This research resulted in a concept called 'My five moments for hand hygiene'. It describes the fundamental reference points for healthcare workers (HCWs) in a time-space framework and designates the moments when hand hygiene is required to effectively interrupt microbial transmission during the care sequence. The concept applies to a wide range of patient care activities and healthcare settings. It proposes a unified vision for trainers, observers and HCWs that should facilitate education, minimize inter-individual variation and resource use, and increase adherence. 'My five moments for hand hygiene' bridges the gap between scientific evidence and daily health practice and provides a solid basis to understand, teach, monitor and report hand hygiene practices.

Hand hygiene monitoring technology: protocol for a systematic review  

PubMed Central

Background Healthcare worker hand hygiene is thought to be one of the most important strategies to prevent healthcare-associated infections, but compliance is generally poor. Hand hygiene improvement interventions must include audits of compliance (almost always with feedback), which are most often done by direct observation - a method that is expensive, subjective, and prone to bias. New technologies, including electronic and video hand hygiene monitoring systems, have the potential to provide continuous and objective monitoring of hand hygiene, regular feedback, and for some systems, real-time reminders. We propose a systematic review of the evidence supporting the effectiveness of these systems. The primary objective is to determine whether hand hygiene monitoring systems yield sustainable improvements in hand hygiene compliance when compared to usual care. Methods/Design MEDLINE, EMBASE, CINAHL, and other relevant databases will be searched for randomized control studies and quasi-experimental studies evaluating a video or electronic hand hygiene monitoring system. A standard data collection form will be used to abstract relevant information from included studies. Bias will be assessed using the Cochrane Effective Practice and Organization of Care Group Risk of Bias Assessment Tool. Studies will be reviewed independently by two reviewers, with disputes resolved by a third reviewer. The primary outcome is directly observed hand hygiene compliance. Secondary outcomes include healthcare-associated infection incidence and improvements in hand hygiene compliance as measured by alternative metrics. Results will be qualitatively summarized with comparisons made between study quality, the measured outcome, and study-specific factors that may be expected to affect outcome (for example, study duration, frequency of feedback, use of real-time reminders). Meta-analysis will be performed if there is more than one study of similar systems with comparable outcome definitions. Discussion Electronic and video monitoring systems have the potential to improve hand hygiene compliance and prevent healthcare-associated infection, but are expensive, difficult to install and maintain, and may not be accepted by all healthcare workers. This review will assess the current evidence of effectiveness of these systems before their widespread adoption. Study registration PROSPERO registration number: CRD42013004519 PMID:24219817



Oral hygiene, dietary pattern and smoking habits of Bedouin (nomadic Arabs) population in Saudi Arabia.  


The estimated population of the Bedouins are up to two million in the Kingdom of Saudi Arabia, but relatively little information is available about them. The aim of the study was to assess the oral hygiene dietary pattern and smoking habits of Saudi Bedouins population around Medina, Qaseen and Khamis Moshayte areas. Five hundred and twenty five Bedouins (296 male, 229 female) with the age range 2-90 years were interviewed and examined clinically over a period of four months (July to October 1998). It was found that 25% of the subjects were miswak users, 30% used miswak and tooth brush, while 26% never cleaned their teeth. Almost 50% of the subjects were regular in their oral hygiene habits. Seventy percent were rice eaters while meat and dates were second and third preference. Tea was the most common drink with 2-3 teaspoons of sugar per cup. Only ten percent were cigarette smokers and less than 5% used shisha (traditional smoking pipe). It is concluded from the study that within the surveyed Bedouin population one fourth of them never cleaned their teeth while almost the same number used miswak (Chewing stick) to clean their teeth. Rice was the most common food item, while tea with refined sugar was the most common drink. Only 15% were smoker. Further research is needed with a larger and a more representative sample of Bedouins from the Kingdom of Saudi Arabia. PMID:14705374

A survey of degree completion programs in dental hygiene education.  


The purpose of this descriptive study was to identify specific information related to U.S. dental hygiene baccalaureate degree completion programs. Learning experiences, assessment methods, and baccalaureate institutional partnerships were assessed. Of the sixty dental hygiene programs that offer a degree completion program, the forty-two that met the inclusion criteria (including having operated for at least three years) were invited to participate in a thirty-eight item online survey. A 62 percent (n=26) response rate was obtained. Learning experiences in responding programs included core dental hygiene courses, general education courses, and elective dental hygiene courses. Emphasis areas offered by various programs were in the specialty areas of education, public or community health, and research. Respondents reported that their graduates were employed in multiple settings (65 percent; n=17), with 19 percent (n=5) reporting employment in the combined grouping of private practice, education, and public health. Institutional partnerships included articulation agreements (88 percent; n=21), community college baccalaureate (8 percent; n=2), and university extension (4 percent; n=1) models. The findings of this study provide a baseline for assessing the educational composition and design of U.S. dental hygiene degree completion programs. However, results of this study showed inconsistencies among learning experiences that might raise concerns when considering students' level of preparation for graduate education and future leadership roles in the profession.

Clinical review: airway hygiene in the intensive care unit.  


Maintenance of airway secretion clearance, or airway hygiene, is important for the preservation of airway patency and the prevention of respiratory tract infection. Impaired airway clearance often prompts admission to the intensive care unit (ICU) and can be a cause and/or contributor to acute respiratory failure. Physical methods to augment airway clearance are often used in the ICU but few are substantiated by clinical data. This review focuses on the impact of oral hygiene, tracheal suctioning, bronchoscopy, mucus-controlling agents, and kinetic therapy on the incidence of hospital-acquired respiratory infections, length of stay in the hospital and the ICU, and mortality in critically ill patients. Available data are distilled into recommendations for the maintenance of airway hygiene in ICU patients. PMID:18423061

Mental hygiene of the special schools teachers in Kerman, Iran.  


The goal of this research is to identify and study the mental hygiene and its related factors (individual, family, organizational) in the Kerman special schools teachers. 266 teachers of the special schools of the cities of the province Kerman were chosen as the research sample. The necessary data were obtained by "questionnaire" which its validity and reliability were determined. The statistical analysis of the research findings (by Spearman coefficient test) Man-Whithey and Kruskal wallis tests showed that there was a positive and meaningful relationship between "Level of education", "service of record" "the number of the members of teacher's family", "income", "dwelling-place", "economic power", "acceptance of the teacher's job in their family", "leadership style", "suitable educational possibilities", "suitable educational space", "job satisfaction" with the mental hygiene of the teachers. The results of the research also showed that the Kerman special schools teachers enjoyed a "relatively desirable" mental hygiene. PMID:15844850

Prioritization of the National Dental Hygiene Research Agenda.  


The profession of dental hygiene has made considerable progress over the past 30 years toward developing a unique body of knowledge for guiding education, practice, and research. The 1993-1994 American Dental Hygienists' Association Council on Research published the first national dental hygiene research agenda in 1994. The 1994 research agenda focused dental hygienists' research efforts; however, publication of two national reports--the Surgeon General's Report on Oral Health, and Healthy People 2010--have made it necessary to revisit the research agenda. After considering input from participants in the Fourth National Dental Hygiene Research Conference and evaluating the Surgeon General's Report, the 2000-2001 Council on Research has established recommendations for the prioritization of the 1993-1994 research agenda. This report outlines for readers the rationale for the proposed recommendations. PMID:12078580

The effect of automated monitoring and real-time prompting on nurses' hand hygiene performance.  


Adequate hand hygiene compliance by healthcare staff is considered an effective method to reduce hospital-acquired infections. The electronic system developed at Toronto Rehabilitation Institute automatically detects hand hygiene opportunities and records hand hygiene actions. It includes an optional visual hand hygiene status indication, generates real-time hand hygiene prompting signals, and enables automated monitoring of individual and aggregated hand hygiene performance. The system was installed on a complex continuous care unit at the entrance to 17 patient rooms and a utility room. A total of 93 alcohol gel and soap dispensers were instrumented and 14 nurses were provided with the personal wearable electronic monitors. The study included three phases with the system operating in three different modes: (1) an inactive mode during the first phase when hand hygiene opportunities and hand hygiene actions were recorded but prompting and visual indication functions were disabled, (2) only hand hygiene status indicators were enabled during the second phase, and (3) both hand hygiene status and real-time hand hygiene prompting signals were enabled during the third phase. Data collection was performed automatically during all of the three phases. The system indicated significantly higher hand hygiene activity rates and compliance during the third phase, with both hand hygiene indication and real-time prompting functions enabled. To increase the efficacy of the technology, its use was supplemented with individual performance reviews of the automatically collected data. PMID:23924823

Hand hygiene monitoring technology: a systematic review of efficacy.  


Electronic and video monitoring systems (EMS/VMS) may improve hand hygiene by providing feedback, real-time reminders or via the Hawthorne effect. The aim of this systematic review was to assess the efficacy of EMS/VMS in improving hand hygiene or reducing the incidence of healthcare-associated infection (HCAI). Experimental and quasi-experimental studies were included if they measured any hand hygiene outcome and/or HCAI incidence. Of the studies included, seven used system-defined compliance (SDC) (N = 6) or hand hygiene event rate (N = 1) as their outcome. SDC differed for all systems. Most (N = 6) were single ward studies. Two uncontrolled pretest?post-test studies evaluating EMS that provided voice prompts showed increases in SDC, but risk of bias was high. Two uncontrolled time-series analyses of VMS that provided aggregate feedback demonstrated large, sustained improvement in SDC and were at moderate risk of bias. One non-randomized controlled trial of EMS with aggregate feedback found no difference in hand hygiene frequency but was at high risk of bias. Two studies evaluated EMS providing individual feedback and real-time reminders. A pretest?post-test study at high risk of bias showed an increase in SDC. An RCT at low risk of bias showed 6.8% higher SDC in the intervention arm partially due to a fall in SDC in the control arm. In conclusion, the overall study quality was poor. The study at lowest risk of bias showed only a small increase in SDC. VMS studies at moderate risk of bias showed rapid and sustained increases in SDC. Data were insufficient to recommend EMS/VMS. Future studies should prioritize testing of VMS using stronger study designs including control arms and validated, system-independent measures of hand hygiene. PMID:25480021

Assessment of tobacco dependence curricula in Italian dental hygiene schools.  


The aim of this study was to assess the level of tobacco dependence education offered by Italian dental hygiene programs. A fifty-question survey was mailed to the thirty-one active public and private dental hygiene programs in Italy during the 2008-09 academic year. The survey assessed faculty confidence in teaching tobacco treatment, which courses contained tobacco dependence content, the number of minutes spent on specific content areas, and the level of clinical competence that dental hygiene graduates should be able to demonstrate. Surveys were returned by sixteen programs for a response rate of 52 percent. Respondents indicated tobacco dependence education was included in clinic or clinic seminar (56 percent), periodontics (44 percent), oral pathology (31 percent), and prevention (19 percent). All programs reported including the effects of tobacco on general and oral diseases in courses. However, more in-depth topics received less curriculum time; these included tobacco treatment strategies (63 percent) and discussion of cessation medications (31 percent). Interestingly, 62 percent of the respondents indicated they expected dental hygiene graduates to demonstrate a tobacco treatment competency level of a moderate intervention or higher (counseling, discussion of medications, follow-up) rather than a brief intervention in which patients are advised to quit then referred to a quitline. The results of this study indicated that Italian dental hygiene students are not currently receiving adequate instruction in tobacco treatment techniques nor are they being adequately assessed. This unique overview of Italian dental hygiene tobacco dependence education provides a basis for further discussion towards a national competency-based curriculum. PMID:23929577

Oral hygiene and compliance as risk factors in periodontitis.  


Periodontitis is an inflammatory disease caused by microbial infection in the subgingival region. Risk factors associated with the development and progression of this disease are numerous, multifactorial, complex, and often not well defined across individuals and population groups. The focus of this paper is to provide an overview of existing information relevant to oral hygiene and compliance as risk factors in periodontitis and to present a 26-month prospective clinical study dealing with the same. The review of literature from epidemiological, clinical, and public health perspectives indicated that oral hygiene can be considered as risk indicator, risk factor, and/or risk predictor. The extent of oral hygiene contribution to the overall risk of individuals and population varies greatly across studies. Such variations may be attributed to population, personal and disease characteristics, research methodology used, and analytical strategies employed. The purpose of the study reported was to determine the role of self-reported daily oral hygiene practices and clinical plaque scores as risk factors in a middle-aged health-conscious population with early periodontitis. The group consisted of 174 subjects selected on the basis of putative bacterial risk markers and clinical indices. Medical, dental, behavioral, and clinical periodontal measurements including plaque, calculus, gingival inflammation, probing depth, bleeding on probing, and relative attachment level were obtained by one of two calibrated examiners at baseline, 14, 20, and 26 months. Data analyses revealed that some trends were seen relevant to self-reported oral hygiene and plaque scores favoring oral hygiene as a possible risk factor in periodontitis. Such trends, however, were neither clear nor consistent across various clinical parameters and observation intervals.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8046570

Enhanced hygiene measures and norovirus transmission during an outbreak.  


Control of norovirus outbreaks relies on enhanced hygiene measures, such as handwashing, surface cleaning, using disposable paper towels, and using separate toilets for sick and well persons. However, little is known about their effectiveness in limiting further spread of norovirus infections. We analyzed norovirus outbreaks in 7 camps at an international scouting jamboree in the Netherlands during 2004. Implementation of hygiene measures coincided with an 84.8% (95% predictive interval 81.2%-86.6%) reduction in reproduction number. This reduction was unexpectedly large but still below the reduction needed to contain a norovirus outbreak. Even more stringent control measures are required to break the chain of transmission of norovirus. PMID:19116045

An analysis of public health policy and legal issues relevant to mobile food vending.  


Mobile food vending is a component of the food environment that has received little attention in the public health literature beyond concerns about food sanitation and hygiene issues. However, several features of mobile food vending make it an intriguing venue for food access. We present key components of mobile vending regulation and provide examples from 12 US cities to illustrate the variation that can exist surrounding these regulations. Using these regulatory features as a framework, we highlight existing examples of "healthy vending policies" to describe how mobile food vending can be used to increase access to nutritious food for vulnerable populations.

Eggs and salmonella food-poisoning: an evaluation  

Microsoft Academic Search

Summary. Evidence on the extent of the part played by infected hens' eggs in causing salmonella food-poisoning is inconclusive. The role of freshly cooked shell eggs is currently much exaggerated. Prevention should be sought through improved catering practices and kitchen hygiene, and attempts to eradicate salmonellas from laying flocks are likely to be ineffective.

A group of Midwestern university students needs to improve their oral hygiene and sugar/pop consumption habits.  


Poor oral hygiene and sugar/pop consumption practices are detrimental to one's overall health. College women were hypothesized to have better oral hygiene habits and to consume less sugar/pop than men and that the students' habits would be different from those the students had before college. These habits of students at a Midwestern university were evaluated by sex. The volunteers included 105 men and 91 women. Three quarters of the students reported brushing their teeth at least the recommended twice daily, with women brushing their teeth more often. About a third of the students flossed at least the recommended once daily. Not quite a third of the students reported brushing and flossing their teeth more often than they did before college. More than a third reported using mouth rinses 4 or more times weekly, with 13% reporting using a fluoride-containing mouth rinse. More than 60% reported using fluoride-containing toothpaste. Slightly more than a third reported drinking fluoridated water in their younger years. A larger percentage of women than men reported that diet pop was their pop of choice. More than two thirds of the students that drank pop indicated that regular pop was their favorite. Most of the students reported consuming sugary foods more than once daily, but they indicated that most of these sugars were not sticky. Few differences were observed in oral hygiene and sugar/pop consumption habits of these college students by sex. Nutritionists and other health professionals should work cooperatively in helping individuals improve their oral hygiene and sugar/pop consumption habits. PMID:20116657

Hygiene inspections on passenger ships in Europe - an overview  

PubMed Central

Background Hygiene inspections on passenger ships are important for the prevention of communicable diseases. The European Union (EU) countries conduct hygiene inspections on passenger ships in order to ensure that appropriate measures have been taken to eliminate potential sources of contamination which could lead to the spread of communicable diseases. This study was implemented within the framework of the EU SHIPSAN project and it investigates the legislation applied and practices of hygiene inspections of passenger ships in the EU Member States (MS) and European Free Trade Association countries. Methods Two questionnaires were composed and disseminated to 28 countries. A total of 92 questionnaires were completed by competent authorities responsible for hygiene inspections (n = 48) and the creation of legislation (n = 44); response rates were 96%, and 75.9%, respectively. Results Out of the 48 responding authorities responsible for hygiene inspections, a routine programme was used by 19 (39.6%) of these to conduct inspections of ships on national voyages and by 26 (54.2%) for ships on international voyages. Standardised inspection forms are used by 59.1% of the authorities. A scoring inspection system is applied by five (11.6%) of the 43 responding authorities. Environmental sampling is conducted by 84.1% of the authorities (37 out of 44). The inspection results are collected and analysed by 54.5% (24 out of 44) of the authorities, while 9 authorities (20.5%) declared that they publish the results. Inspections are conducted during outbreak investigations by 75% and 70.8% of the authorities, on ships on national and international voyages, respectively. A total of 31 (64.6%) and 39 (81.3%) authorities conducted inspections during complaint investigations on ships on international and on national voyages, respectively. Port-to-port communication between the national port authorities was reported by 35.4% (17 out of 48) of the responding authorities and 20.8% (10 out of 48) of the port authorities of other countries. Conclusion This study revealed a diversity of approaches and practices in the conduct of inspections, differences in the qualifications/knowledge/experience of inspectors, the legislation applied during inspections, and the lack of communication and training among many EU countries. An integrated European inspection programme involving competent expert inspectors in each EU Member States and special training for ship hygiene delivered to crew members and inspectors would help to minimize the risk of communicable diseases. Common inspection tools at a European level for hygiene inspection practices and port-to-port communication are needed. PMID:20219097



Application of the human needs conceptual model of dental hygiene to the role of the clinician : part II.  


In summary, the theories of Maslow and of Yura and Walsh have been highlighted as background for understanding the human needs conceptual model of dental hygiene. In addition, 11 human needs have been identified and defined as being especially related to dental hygiene care, and a sample evaluation tool for their clinical assessment and a dental hygiene care plan have been presented. The four concepts of client, environment, health/oral health, and dental hygiene actions explained in terms of human need theory, and the 11 human needs related to dental hygiene care constitute the human needs conceptual model of dental hygiene. Within the framework of the human needs conceptual model of dental hygiene, the dental hygiene process is a systematic approach to dental hygiene care that involves assessment of the 11 human needs related to dental hygiene care; analysis of deficits in these needs; determination of the dental hygiene care plan based on identified deficits; implementation of dental hygiene interventions stated in the care plan; and evaluation of the effectiveness of dental hygiene interventions in achieving specific goals, including subsequent reassessment and revision of the dental hygiene care plan. This human needs conceptual model for dental hygiene provides a guide for comprehensive and humanistic client care. This model allows the dental hygienist to view each client (whether an individual or a group) holistically to prevent oral disease and to promote health and wellness. Dental hygiene theorists are encouraged to expand this model or to develop additional conceptual models based on dental hygiene's paradigm. PMID:17233167

Baseline evaluation of hand hygiene compliance in three major hospitals, Isfahan, Iran.  


Hand hygiene is the mainstay of nosocomial infection prevention. This study was a baseline survey to assess hand hygiene compliance of healthcare workers by direct observation in three major hospitals of Isfahan, Iran. The use of different hand hygiene products was also evaluated. In 3078 potential opportunities hand hygiene products were available on 2653 occasions (86.2%). Overall compliance was 6.4% (teaching hospital: 7.4%; public hospital: 6.2%; private hospital: 1.4%). Nurses (8.4%) had the highest rates of compliance. Poor hand hygiene compliance in Isfahan hospitals necessitates urgent interventions to improve both hospital infrastructure and staff knowledge. PMID:23910401

Hygiene behaviour and hospitalized severe childhood diarrhoea: a case-control study.  

PubMed Central

The relationship between personal and domestic hygiene behaviour and hospitalized childhood diarrhoea was examined in a case-control study of 356 cases and 357 controls from low-income families in metropolitan Manila. Indices of hygiene behaviour were defined for overall cleanliness, kitchen hygiene, and living conditions. Only the indices for overall cleanliness and kitchen hygiene were significantly associated with diarrhoea. An increasing excess risk of hospitalization with severe diarrhoea was noted as the ratings for standards of hygiene became lower, and this excess risk persisted even after controlling for confounding variables. The implications of our findings for the control of diarrhoeal disease are discussed. PMID:8324851

Impact of rural water projects on hygienic behaviour in Swaziland  

NASA Astrophysics Data System (ADS)

In Swaziland, access to safe water supply and sanitation has improved significantly and was expected to result in improved health and, in particular, reduced infant mortality rates. On the contrary, mortality rates in the under 5 years age group are high and have doubled from 60 in 1996, to 120 deaths per 1000 in 2006. The main objective of the study was to assess whether the water projects permit, and are accompanied by, changes in hygienic behaviour to prevent transmission of diseases. The study area was Phonjwane, located in the dry Lowveld of Swaziland, where water projects play a significant role in meeting domestic water demands. Hygienic behaviour and sanitation facilities were analysed and compared before and after project. The results of the study show that domestic water supply projects have significantly reduced distances travelled and time taken to collect water, and that increased quantities of water are collected and used. While the majority of respondents (95.6%) used the domestic water project source, the quantities allowed per household (125 l which translates to an average of 20.8 l per person) were insufficient and therefore were supplemented with harvested rainwater (57.8%), water from a polluted river (17.8%), and water from a dam (2.2%). Increased water quantities have permitted more baths and washing of clothes and hands, but significant proportions of the population still skip hygienic practices such as keeping water for washing hands inside or near toilet facilities (40%) and washing hands (20%). The study concludes that the water supply project has permitted and improved hygienic practices but not sufficiently. The health benefits of safe domestic water supplies are hampered by insufficient quantities of water availed through the projects, possible contamination of the water in the house, poor hygienic behaviours and lack of appropriate sanitation measures by some households. There is a need to provide sufficient quantities of safe water to meet all domestic demands. Domestic water supply must be accompanied by appropriate sanitation and hygienic education.

Probiotics and food allergy.  


The exact prevalence of food allergy in the general population is unknown, but almost 12% of pediatric population refers a suspicion of food allergy. IgE mediated reactions to food are actually the best-characterized types of allergy, and they might be particularly harmful especially in children. According to the "hygiene hypothesis" low or no exposure to exogenous antigens in early life may increase the risk of allergic diseases by both delaying the development of the immune tolerance and limiting the Th2/Th1 switch. The critical role of intestinal microbiota in the development of immune tolerance improved recently the interest on probiotics, prebiotics, antioxidants, polyunsaturated fatty acid, folate and vitamins, which seem to have positive effects on the immune functions.Probiotics consist in bacteria or yeast, able to re-colonize and restore microflora symbiosis in intestinal tract. One of the most important characteristics of probiotics is their safety for human health. Thanks to their ability to adhere to intestinal epithelial cells and to modulate and stabilize the composition of gut microflora, probiotics bacteria may play an important role in the regulation of intestinal and systemic immunity. They actually seem capable of restoring the intestinal microbic equilibrium and modulating the activation of immune cells.Several studies have been recently conducted on the role of probiotics in preventing and/or treating allergic disorders, but the results are often quite contradictory, probably because of the heterogeneity of strains, the duration of therapy and the doses administered to patients. Therefore, new studies are needed in order to clarify the functions and the utility of probiotics in food allergies and ion other types of allergic disorders. PMID:23895430

The importance and provision of oral hygiene in surgical patients.  


The provision of mouth care on the general surgical ward and intensive care setting has recently gained momentum as an important aspect of patient care. Oropharyngeal morbidity can cause pain and disordered swallowing leading to reluctance in commencing or maintaining an adequate dietary intake. On the intensive care unit, aside from patient discomfort and general well-being, oral hygiene is integral to the prevention of ventilator-associated pneumonia. Chlorhexidine (0.2%) is widely used to decrease oral bacterial loading, dental bacterial plaque and gingivitis. Pineapple juice has gained favour as a salivary stimulant in those with a dry mouth or coated tongue. Tooth brushing is the ideal method of promoting oral hygiene. Brushing is feasible in the vast majority, although access is problematic in ventilated patients. Surgical patients undergoing palliative treatment are particularly prone to oral morbidity that may require specific but simple remedies. Neglect of basic aspects of patient care, typified by poor oral hygiene, can be detrimental to surgical outcome. PMID:18947816

Measuring hygiene and health perfomance of buildings: a multidimensional approach.  


This paper proposes an innovative and transparent methodology to support the "ASL Milano" (Local Health Agency) in the hygiene and health evaluation of construction projects, in order to highlight their positive and negative performance beyond the requirements imposed by the current laws and regulations regarding buildings' hygiene performance, which are too old and therefore unsuitable to ascertain the real quality of indoor environments. The compliance with laws or regulations, mostly out of date, and the assessment of performance involving only a part of the current emerging needs and problems, in fact, should be considered as a necessary, although not a sufficient step, to ensure high quality indoors. Consequently, it is necessary to identify and test an assessment tool which could provide an effective and flexible support for the development of hygiene and health statements regarding projects at building scale (new construction, conversion of the existing, rehabilitation, extension, change of use, etc). The assessment tool suggested by this paper is tailored for the metropolitan area of the city of Milan, but its evaluation framework could be developed and applied to other contexts. PMID:23471453

Review series on helminths, immune modulation and the hygiene hypothesis: The broader implications of the hygiene hypothesis  

PubMed Central

Man has moved rapidly from the hunter–gatherer environment to the living conditions of the rich industrialized countries. The hygiene hypothesis suggests that the resulting changed and reduced pattern of exposure to microorganisms has led to disordered regulation of the immune system, and hence to increases in certain inflammatory disorders. The concept began with the allergic disorders, but there are now good reasons for extending it to autoimmunity, inflammatory bowel disease, neuroinflammatory disorders, atherosclerosis, depression associated with raised inflammatory cytokines, and some cancers. This review discusses these possibilities in the context of Darwinian medicine, which uses knowledge of evolution to cast light on human diseases. The Darwinian approach enables one to correctly identify some of the organisms that are important for the ‘Hygiene’ or ‘Old Friends’ hypothesis, and to point to the potential exploitation of these organisms or their components in novel types of prophylaxis with applications in several branches of medicine.

Impact of a Hygiene Curriculum and the Installation of Simple Handwashing and Drinking Water Stations in Rural Kenyan Primary Schools on Student Health and Hygiene Practices  

PubMed Central

School-based hygiene and water treatment programs increase student knowledge, improve hygiene, and decrease absenteeism, however health impact studies of these programs are lacking. We collected baseline information from students in 42 schools in Kenya. We then instituted a curriculum on safe water and hand hygiene and installed water stations in half (“intervention schools”). One year later, we implemented the intervention in remaining schools. Through biweekly student household visits and two annual surveys, we compared the effect of the intervention on hygiene practices and reported student illness. We saw improvement in proper handwashing techniques after the school program was introduced. We observed a decrease in the median percentage of students with acute respiratory illness among those exposed to the program; no decrease in acute diarrhea was seen. Students in this school program exhibited sustained improvement in hygiene knowledge and a decreased risk of respiratory infections after the intervention. PMID:22869631

Effect of Hand Hygiene on Infectious Disease Risk in the Community Setting: A Meta-Analysis  

PubMed Central

To quantify the effect of hand-hygiene interventions on rates of gastrointestinal and respiratory illnesses and to identify interventions that provide the greatest efficacy, we searched 4 electronic databases for hand-hygiene trials published from January 1960 through May 2007 and conducted meta-analyses to generate pooled rate ratios across interventions (N=30 studies). Improvements in hand hygiene resulted in reductions in gastrointestinal illness of 31% (95% confidence intervals [CI]=19%, 42%) and reductions in respiratory illness of 21% (95% CI=5%, 34%). The most beneficial intervention was hand-hygiene education with use of nonantibacterial soap. Use of antibacterial soap showed little added benefit compared with use of nonantibacterial soap. Hand hygiene is clearly effective against gastrointestinal and, to a lesser extent, respiratory infections. Studies examining hygiene practices during respiratory illness and interventions targeting aerosol transmission are needed. PMID:18556606

The role of self-regulation in predicting sleep hygiene in university students.  


University students have poor sleep hygiene, leading to poorer health. Facets of self-regulation such as planning, behavioural inhibition, cognitive flexibility and working memory were explored in relation to three sleep hygiene behaviours: Avoiding stress or anxiety before bed, avoiding going to bed hungry or thirsty, and making the bedroom restful. One hundred and thirty-seven participants took part in an Internet-based survey over two time points separated by a period of two weeks. Only cognitive flexibility and behavioural inhibition correlated with sleep hygiene. Cognitive flexibility significantly predicted an aspect of sleep hygiene after controlling for past behaviour. However, when past behaviour was controlled for, behavioural inhibition no longer predicted sleep hygiene. Thus, cognitive flexibility may play a role in explaining sleep hygiene; however, behavioural inhibition does not appear as important as previously assumed. Further research could build on this study to determine whether cognitive flexibility can be experimentally improved. PMID:22788412

Video observation of hand hygiene practices during routine companion animal appointments and the effect of a poster intervention on hand hygiene compliance  

PubMed Central

Background Hand hygiene is considered one of the most important infection control measures in human healthcare settings, but there is little information available regarding hand hygiene frequency and technique used in veterinary clinics. The objectives of this study were to describe hand hygiene practices associated with routine appointments in companion animal clinics in Ontario, and the effectiveness of a poster campaign to improve hand hygiene compliance. Results Observation of hand hygiene practices was performed in 51 clinics for approximately 3 weeks each using 2 small wireless surveillance cameras: one in an exam room, and one in the most likely location for hand hygiene to be performed outside the exam room following an appointment. Data from 38 clinics were included in the final analysis, including 449 individuals, 1139 appointments before and after the poster intervention, and 10894 hand hygiene opportunities. Overall hand hygiene compliance was 14% (1473/10894), while before and after patient contact compliance was 3% (123/4377) and 26% (1145/4377), respectively. Soap and water was used for 87% (1182/1353) of observed hand hygiene attempts with a mean contact time of 4 s (median 2 s, range 1-49 s), while alcohol-based hand rub (ABHR) was used for 7% (98/1353) of attempts with a mean contact time of 8 s (median 7 s, range 1-30 s). The presence of the posters had no significant effect on compliance, although some staff reported that they felt the posters did increase their personal awareness of the need to perform hand hygiene, and the posters had some effect on product contact times. Conclusions Overall hand hygiene compliance in veterinary clinics in this study was low, and contact time with hand hygiene products was frequently below current recommendations. Use of ABHR was low despite its advantages over hand washing and availability in the majority of clinics. The poster campaign had a limited effect on its own, but could still be used as a component of a multimodal hand hygiene campaign. Improving the infection control culture in veterinary medicine would facilitate future campaigns and studies in this area, as well as overall patient and staff safety. PMID:24885304



Food masquerade.  


Radishes cut to look like roses, watermelons carved into fruit baskets, apples made into swans, cakes frosted to look like dolls—when did this game of food masquerade start and how? This essay speculates about food's on-going history of disguise, of pretending to be what it's not. From the Renaissance courtier's delight in confections disguised as beasts, birds, and other fancies to our present day fascination with Japanese bento lunch boxes, food masquerade would seem to be a fanciful part of the history of food.Food masquerade injects some levity into our growing seriousness about food, our suspicion that most supermarket food is riddled with toxins and bad karma. It proposes that eating food should be fun. Food masquerade also gets to the very heart of artistic visual representation: the magical transformation of paint, clay or wood into an image of something else. It is a synecdoche for art itself.

Systemic mistakes in hand hygiene practice in Ukraine: detection, consequences and ways of elimination  

PubMed Central

Aim: Every year, millions of people around the world suffer from different infectious diseases, considerable part of which are hospital-acquired infections. WHO considers hand hygiene as a priority measure aimed to reduce the level of infection. We evaluated various aspects related to the situational behavior and prioritization regarding hand hygiene measures among the healthcare workers of Ukraine. Method: Identification of system mistakes in hand hygiene was carried out first of all by direct and indirect observation of the activities of medical and pharmaceutical personnel in their everyday practice as well as during their participation in trainings on routine hand hygiene. Questionnaires also were used to estimate the level of hand hygiene compliance of participants of the study. During this period 112 training courses, 315 master-classes and presentations on proper hand hygiene were realized. The target audience included health care workers of medical centers, clinics, maternity hospitals, health care organizations and staff of pharmacies and pharmaceutical manufacturing enterprises in all regions of Ukraine. 638 respondents took part in anonymous survey on hand hygiene practice. Results: The most common mistakes were to regard hand washing and hand disinfection equally, to wash hands before doing a hand disinfection, to neglect the five moments for hand hygiene and to ignore hand hygiene before and after wearing protective gloves. Practitioners, medical attendants, pharmacy and pharmaceutical industry workers highlighted the need for practical and understandable instructions of various hand hygiene procedures, including the clarification of the possible technical mistakes. This became a ground for us to create individual master classes on hand hygiene for each cluster of healthcare workers. Conclusions: Changing hand hygiene behavior and attitude is possible by beginning to observe clinical practice and by involving healthcare workers in teaching and training.

Hygienic behavior of the honey bee (Apis mellifera) is independent of sucrose responsiveness and foraging ontogeny.  


Hygienic behavior in honey bees is a behavioral mechanism of disease resistance. Bees bred for hygienic behavior exhibit an increased olfactory sensitivity to odors of diseased brood, which is most likely differentially enhanced in the hygienic line by the modulatory effects of octopamine (OA), a noradrenaline-like neuromodulator. Here, we addressed whether the hygienic behavioral state is linked to other behavioral activities known to be modulated by OA. We specifically asked if, during learning trials, bees from hygienic colonies discriminate better between odors of diseased and healthy brood because of differences in sucrose (reward) response thresholds. This determination had to be tested because sucrose response thresholds are susceptible to OA modulation and may have influenced the honey bee's association of the conditioned stimulus (odor) with the unconditioned stimulus (i.e., the sucrose reward). Because the onset of first foraging is also modulated by OA, we also examined whether bees from hygienic colonies differentially forage at an earlier age compared to bees from non-hygienic colonies. Our study revealed that 1-day- and 15- to 20-day-old bees from the hygienic line do not have lower sucrose response thresholds compared to bees from the non-hygienic lines. In addition, hygienic bees did not forage at an earlier age or forage preferentially for pollen as compared to non-hygienic bees. These results support the idea that OA does not function in honey bees simply to enhance the detection of all chemical cues non-selectively or control related behaviors regardless of their environmental milieu. Our results indicate that the behavioral profile of the hygienic bee is sculpted by multiple factors including genetic, neural, social and environmental systems. PMID:16225878

The relationship between hand hygiene and health care-associated infection: it’s complicated  

PubMed Central

The reasoning that improved hand hygiene compliance contributes to the prevention of health care-associated infections is widely accepted. It is also accepted that high hand hygiene alone cannot impact formidable risk factors, such as older age, immunosuppression, admission to the intensive care unit, longer length of stay, and indwelling devices. When hand hygiene interventions are concurrently undertaken with other routine or special preventive strategies, there is a potential for these concurrent strategies to confound the effect of the hand hygiene program. The result may be an overestimation of the hand hygiene intervention unless the design of the intervention or analysis controls the effect of the potential confounders. Other epidemiologic principles that may also impact the result of a hand hygiene program include failure to consider measurement error of the content of the hand hygiene program and the measurement error of compliance. Some epidemiological errors in hand hygiene programs aimed at reducing health care-associated infections are inherent and not easily controlled. Nevertheless, the inadvertent omission by authors to report these common epidemiological errors, including concurrent infection prevention strategies, suggests to readers that the effect of hand hygiene is greater than the sum of all infection prevention strategies. Worse still, this omission does not assist evidence-based practice.

Behaviour change for better health: nutrition, hygiene and sustainability.  


As the global population grows there is a clear challenge to address the needs of consumers, without depleting natural resources and whilst helping to improve nutrition and hygiene to reduce the growth of noncommunicable diseases. For fast-moving consumer goods companies, like Unilever, this challenge provides a clear opportunity to reshape its business to a model that decouples growth from a negative impact on natural resources and health. However, this change in the business model also requires a change in consumer behaviour. In acknowledgement of this challenge Unilever organised a symposium entitled 'Behaviour Change for Better Health: Nutrition, Hygiene and Sustainability'. The intention was to discuss how consumers can be motivated to live a more healthy and sustainable lifestlye in today's environment. This article summarises the main conclusions of the presentations given at the symposium. Three main topics were discussed. In the first session, key experts discussed how demographic changes - particularly in developing and emerging countries - imply the need for consumer behaviour change. The second session focused on the use of behaviour change theory to design, implement and evaluate interventions, and the potential role of (new or reformulated) products as agents of change. In the final session, key issues were discussed regarding the use of collaborations to increase the impact and reach, and to decrease the costs, of interventions. The symposium highlighted a number of key scientific challenges for Unilever and other parties that have set nutrition, hygiene and sustainability as key priorities. The key challenges include: adapting behaviour change approaches to cultures in developing and emerging economies; designing evidence-based behaviour change interventions, in which products can play a key role as agents of change; and scaling up behaviour change activities in cost-effective ways, which requires a new mindset involving public-private partnerships.

Hand hygiene is crucial to combat Clostridium difficile.  


Patients with Clostridium difficile infection (CDI) can contaminate the environment with spores that are able to survive for months. A previous room occupant with CDI is a significant risk factor for developing the infection. Room cleaning with commonly used disinfectants will not kill spores. Sodium hypochlorite and hydrogen peroxide are effective but correct concentration and contact time are important. Hand hygiene is a crucial element in preventing infection. In the UK, there is a clear recommendation for handwashing, rather than alcohol-based hand rub, when caring for patients with CDI. PMID:25258234



[Food allergy or food intolerance?].  


Adverse food reactions can be classified into two main categories depending on wether an immune mechanism is involved or not. The first category includes immune mediated reactions like IgE mediated food allergy, eosinophilic oesophagitis, food protein-induced enterocolitis syndrome and celiac disease. The second category implies non-immune mediated adverse food reactions, also called food intolerances. Intoxications, pharmacologic reactions, metabolic reactions, physiologic, psychologic or reactions with an unknown mechanism belong to this category. We present a classification of adverse food reactions based on the pathophysiologic mechanism that can be useful for both diagnostic approach and management. PMID:24834642

[Reliability of a questionnaire to assess food safety knowledge, perceptions, and practices among outpatients with human immunodeficiency virus].  


HIV-positive patients are at increased risk of acquiring infections, particularly those related to water and food. The risk could be reduced by educational interventions in the clinical setting related to food safety for the prevention of food-borne diseases. The current study aimed to analyze food safety knowledge, perceptions, and practices among HIV-positive outpatients. A questionnaire was organized with five behavioral areas (cross contamination; personal hygiene; household hygiene; temperature control; and control of unsafe foods). The test-retest procedure demonstrated the questionnaire's reliability. Kappa values varied among the questions: high for 84.6% (33); moderate for 12.8% (5); and low for 2.5% (1). Based on the results, the instrument showed good reliability for most of the questions and can be used for surveys on food safety in HIV-positive outpatients. PMID:17435894

[Hygienic characteristics of food hydrolysates made from small ocean fish and krill].  


A study was made of the biological value of acid and enzymatic hydrolysates from capelin, luminous anchovy and krill. Hydrolysates were obtained with the use of protosubtilin G-10-X or hydrochloric acid. The products were found to contain 39 to 64% of "crude" protein, with about 40% of total nitrogen belonging to non-protein one, 0.47-2.07% of lipids, 29.7-54.3% of mineral substances including 26.6-52.4% of sodium chloride. All the hydrolysates were limited in tryptophan, the deficiency being more demonstrable in acid hydrolysates. Enzymatic hydrolysate from luminous anchovy was rich in sulfur-containing amino acids (score 112%), whereas the remaining products were marked by their deficiency (score 53-90%). The products were rich in lysine, leucine, isoleucine, and aromatic amino acids. The anabolic efficacy was discovered to be the highest for enzymatic hydrolysate from luminous anchovy, exceeding the analogous characteristics for casein. The biological value of hydrolysate from capelin and krill was lower than that of casein. This was supported by the amino acid analysis data. The assimilability of all hydrolysates was established as fairly high. Hydrolysates are employed for manufacturing broth bricks and pastes. PMID:4082514

Hygiene status of rural communities in the Eastern Cape of South Africa.  


A descriptive study was conducted to determine hygiene status of rural communities in the Eastern Cape, South Africa, using a purposive sample of 145 villagers: 71 male and 74 female. Participants were divided into 14 groups (by community) and group interviews were conducted with them. Communities neither had enough water (92.9%) nor treated drinking water (71.4%); sizeable numbers did not store drinking water safely; threw waste water away (92.9%) and solid waste in the rubbish pit (78.6%); where there are no toilets, they relieved themselves in the veld; children <12 years generally did not use toilets (71.4%). Communities washed hands after changing baby's nappy (78.6%), before handling food (57.1%), before eating (50.0%), after a visit to the toilet (92.9%), after touching animals (57.1%) and when they wake up (92.9%); and did not take a full body wash daily (71.4%). The results have implications for policy-makers, programme planners, academics and practitioners in the field. PMID:16854674

The impact of hygiene and localised treatment on the quality of drinking water in Masaka, Rwanda.  


The worldwide prevalence of waterborne diseases has been attributed to the lack of safe water, inadequate sanitation and hygiene. This study evaluated socio-demographic factors, microbiological quality of water at source and point of use (POU) at households, water handling and sanitation practices in a rural Rwandan community. Thirty five water samples from the source, Nyabarongo River, and water at point of use (POU) treated with the Slow Sand Filter (SSF) and Sûr'Eau methods, were analysed for total coliform and faecal coliform counts. Turbidity was measured in household samples. A structured questionnaire regarding water collection, storage, usage and waterborne disease awareness was administered to 324 women. Despite the significant reduction in coliforms and faecal coliforms from the Nyabarongo River following treatment using either SSF or Sûr'Eau, the water at point of use was found to be unsafe for human consumption. The frequency of diarrheal diseases were significantly higher among people who did not wash hands before food preparation (P = 0.002) and after using a toilet (P = 0.007) than among those who did. There was a statistically significant association between education levels and water treatment practices at the households (P < 0.05). Participants had limited knowledge regarding water storage practices for prevention of household water contamination. A combination of treatment methods with appropriate water handling should be considered. In addition, education is a fundamental precursor to advocating water treatment at POU. PMID:24345241

CFD Model of Water Droplet Transport for ISS Hygiene Activity  

NASA Technical Reports Server (NTRS)

The goal of the study is to assess the impacts of free water propagation in the Waste and Hygiene Compartment (WHC). Free water can be generated inside the WHC in small quantities due to crew hygiene activity. To mitigate potential impact of free water in Node 3 cabin the WHC doorway is enclosed by a waterproof bump-out, Kabin, with openings at the top and bottom. At the overhead side of the rack, there is a screen that prevents large drops of water from exiting. However, as the avionics fan in the WHC causes airflow toward the deck side of the rack, small quantities of free water may exit at the bottom of the Kabin. A Computational Fluid Dynamics (CFD) analysis of Node 3 cabin airflow made possible to identify the paths of water transport. The Node 3 airflow was computed for several ventilation scenarios. To simulate the droplet transport the Lagrangian discrete phase approach was used. Various initial droplet distributions were considered in the study. The droplet diameter was varied in the range of 2-20 mm. The results of the computations showed that most of the drops fall to the rack surface not far from the WHC curtain. The probability of the droplet transport to the adjacent rack surface with electronic equipment was predicted.

International Space Station USOS Waste and Hygiene Compartment Development  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) currently provides human waste collection and hygiene facilities in the Russian Segment Service Module (SM) which supports a three person crew. Additional hardware is planned for the United States Operational Segment (USOS) to support expansion of the crew to six person capability. The additional hardware will be integrated in an ISS standard equipment rack structure that was planned to be installed in the Node 3 element; however, the ISS Program Office recently directed implementation of the rack, or Waste and Hygiene Compartment (WHC), into the U.S. Laboratory element to provide early operational capability. In this configuration, preserved urine from the WHC waste collection system can be processed by the Urine Processor Assembly (UPA) in either the U.S. Lab or Node 3 to recover water for crew consumption or oxygen production. The human waste collection hardware is derived from the Service Module system and is provided by RSC-Energia. This paper describes the concepts, design, and integration of the WHC waste collection hardware into the USOS including integration with U.S. Lab and Node 3 systems.

Status of the International Space Station Waste and Hygiene Compartment  

NASA Technical Reports Server (NTRS)

The Waste and Hygiene Compartment (WHC) serves as the primary system for removal and containment of metabolic waste and hygiene activities on board the United States segment of the International Space Station (ISS). The WHC was launched on ULF 2 and is currently in the U.S. Laboratory and is integrated into the Water Recovery System (WRS) where pretreated urine is processed by the Urine Processor Assembly (UPA). The waste collection part of the WHC system is derived from the Service Module system and was provided by RSC-Energia along with additional hardware to allow for urine delivery to the UPA. The System has been integrated in an ISS standard equipment rack structure for use on the U.S. segment of the ISS. The system has experienced several events of interest during the deployment, checkout, and operation of the system during its first year of use and these will be covered in this paper. Design and on-orbit performance will also be discussed.

Hygiene and the world distribution of Alzheimer’s disease  

PubMed Central

Background and objectives: Alzheimer’s disease (AD) shares certain etiological features with autoimmunity. Prevalence of autoimmunity varies between populations in accordance with variation in environmental microbial diversity. Exposure to microorganisms may improve individuals’ immunoregulation in ways that protect against autoimmunity, and we suggest that this may also be the case for AD. Here, we investigate whether differences in microbial diversity can explain patterns of age-adjusted AD rates between countries. Methodology: We use regression models to test whether pathogen prevalence, as a proxy for microbial diversity, across 192 countries can explain a significant amount of the variation in age-standardized AD disability-adjusted life-year (DALY) rates. We also review and assess the relationship between pathogen prevalence and AD rates in different world populations. Results: Based on our analyses, it appears that hygiene is positively associated with AD risk. Countries with greater degree of sanitation and lower degree of pathogen prevalence have higher age-adjusted AD DALY rates. Countries with greater degree of urbanization and wealth exhibit higher age-adjusted AD DALY rates. Conclusions and implications: Variation in hygiene may partly explain global patterns in AD rates. Microorganism exposure may be inversely related to AD risk. These results may help predict AD burden in developing countries where microbial diversity is rapidly diminishing. Epidemiological forecasting is important for preparing for future healthcare needs and research prioritization. PMID:24481197

Food allergies and food intolerances.  


Adverse reactions to foods, aside from those considered toxic, are caused by a particular individual intolerance towards commonly tolerated foods. Intolerance derived from an immunological mechanism is referred to as Food Allergy, the non-immunological form is called Food Intolerance. IgE-mediated food allergy is the most common and dangerous type of adverse food reaction. It is initiated by an impairment of normal Oral Tolerance to food in predisposed individuals (atopic). Food allergy produces respiratory, gastrointestinal, cutaneous and cardiovascular symptoms but often generalized, life-threatening symptoms manifest at a rapid rate-anaphylactic shock. Diagnosis is made using medical history and cutaneous and serological tests but to obtain final confirmation a Double Blind Controlled Food Challenge must be performed. Food intolerances are principally caused by enzymatic defects in the digestive system, as is the case with lactose intolerance, but may also result from pharmacological effects of vasoactive amines present in foods (e.g. Histamine). Prevention and treatment are based on the avoidance of the culprit food. PMID:16782524

Quantitative microbial risk assessment of antibacterial hand hygiene products on risk of shigellosis.  


There are conflicting reports on whether antibacterial hand hygiene products are more effective than nonantibacterial products in reducing bacteria on hands and preventing disease. This research used new laboratory data, together with simulation techniques, to compare the ability of nonantibacterial and antibacterial products to reduce shigellosis risk. One hundred sixtythree subjects were used to compare five different hand treatments: two nonantibacterial products and three antibacterial products, i.e., 0.46% triclosan, 4% chlorhexidine gluconate, or 62% ethyl alcohol. Hands were inoculated with 5.5 to 6 log CFU Shigella; the simulated food handlers then washed their hands with one of the five products before handling melon balls. Each simulation scenario represented an event in which 100 people would be exposed to Shigella from melon balls that had been handled by food workers with Shigella on their hands. Analysis of experimental data showed that the two nonantibacterial treatments produced about a 2-log reduction on hands. The three antibacterial treatments showed log reductions greater than 3 but less than 4 on hands. All three antibacterial treatments resulted in statistically significantly lower concentration on the melon balls relative to the nonantibacterial treatments. A simulation that assumed 1 million Shigella bacteria on the hands and the use of a nonantibacterial treatment predicted that 50 to 60 cases of shigellosis would result (of 100 exposed). Each of the antibacterial treatments was predicted to result in an appreciable number of simulations for which the number of illness cases would be 0, with the most common number of illness cases being 5 (of 100 exposed). These effects maintained statistical significance from 10(6) Shigella per hand down to as low as 100 Shigella per hand, with some evidence to support lower levels. This quantitative microbial risk assessment shows that antibacterial hand treatments can significantly reduce Shigella risk. PMID:24680068

Hygienic and health characteristics of donkey milk during a follow-up study.  


For its characteristics, donkey milk has been proposed as an alternative to goat or artificial milk to feed allergic infants. Therefore, it is important to increase our knowledge on health and immunological characteristics of donkey milk. Ten donkeys, bred as companion animals, were enrolled in this study and sampled once a month, for eight months. Milk (10 ml) was collected from each half udder for somatic cell count (SCC), bacteriological analysis and total bacteria count (TBC). The major pathogens were tested for antimicrobial susceptibility, and Staphylococcus aureus isolates were further genotyped by nanoarray analysis. Whey lysozyme and NAGase (NAG) activities were also assessed. Overall, 101 half-udder milk samples were taken. They showed very low values of TBC (<250 cfu/ml) and SCC (<50 000 cells/ml) and a minor prevalence of pathogens: Staph. aureus was isolated only from 5 milk samples (3 animals), Streptococcus equi from 2 samples and Str. equisimilis from a single sample. All the isolates were sensitive to all antibiotic classes used in veterinary medicine. None of the Staph. aureus isolates were shown to harbour genes coding for any enterotoxin, toxic-shock syndrome toxin or antibiotic resistance. Lysozyme levels were always very high (4000-5000 U/ml), while NAG values were mostly low (<50 U/ml), out of the last part of lactation. The results of this study confirmed the low prevalence of intramammary infections in donkey and the absence of food-borne pathogens, suggesting that donkey milk could be a safe food, if the mammary gland is healthy and the animals are milked in proper hygienic conditions.

Nutritional status of iodine in pregnant women in Catalonia (Spain): study on hygiene-dietetic habits and iodine in urine  

PubMed Central

Background It is a priority to achieve an adequate nutritional status of iodine during pregnancy since iodine deficiency in this population may have repercussions on the mother during both gestation and post partum as well as on the foetus, the neonate and the child at different ages. According to the WHO, iodine deficiency is the most frequent cause of mental retardation and irrreversible cerebral lesions around the world. However, few studies have been published on the nutritional status of iodine in the pregnant population within the Primary Care setting, a health care level which plays an essential role in the education and control of pregnant women. Therefore, the aim of the present study is: 1.- To know the hygiene-dietetic habits related to the intake of foods rich in iodine and smoking during pregnancy. 2.- To determine the prevalence of iodine deficiency and the factors associated with its appearance during pregnancy. Methods/design We will perform a cluster randomised, controlled, multicentre trial. Randomisation unit: Primary Care Team. Study population: 898 pregnant women over the age of 17 years attending consultation to a midwife during the first trimester of pregnancy in the participating primary care centres. Outcome measures: consumption of iodine-rich foods and iodine deficiency. Points of assessment: each trimester of the gestation. Intervention: group education during the first trimester of gestation on healthy hygiene-dietetic habits and the importance of an adequate iodine nutritional status. Statistical analysis: descriptive analysis of all variables will be performed as well as multilevel logistic regression. All analyses will be done carried out on an intention to treat basis and will be fitted for potential confounding factors and variables of clinical importance. Discussion Evidence of generalised iodine deficiency during pregnancy could lead to the promotion of interventions of prevention such as how to improve and intensify health care educational programmes for pregnant women. Trial Registration NCT01301768 PMID:21385426

Hygiene hypothesis in inflammatory bowel disease: A critical review of the literature  

PubMed Central

The hygiene hypothesis is thought to be a significant contributor to the growing incidence of inflammatory bowel disease (IBD) around the world, although the evidence for specific factors that underlie the hygiene hypothesis in IBD is unclear. We aimed to systematically review the literature to determine which hygiene-related factors are associated with the development of IBD. Publications identified from a broad based MEDLINE and Current Contents search between 1966 and 2007 on key terms relevant to the 'hygiene hypothesis' and IBD including H pylori exposure, helminths, cold chain hypothesis, measles infection and vaccination, antibiotic use, breastfeeding, family size, sibship, urban upbringing, day care attendance and domestic hygiene were reviewed. The literature suggests that the hygiene hypothesis and its association with decreased microbial exposure in childhood probably plays an important role in the development of IBD, although the strength of the supporting data for each of the factors varies considerably. The most promising factors that may potentially be associated with development of IBD include H pylori exposure, helminths, breastfeeding and sibship. However, the vast majority of studies in this area are plagued by serious methodological shortcomings, particularly the reliance on retrospective recall of information making it difficult to truly ascertain the importance of a 'hygiene hypothesis' in IBD. The 'hygiene hypothesis' in IBD is an important area of research that may give clues to the aetiology of this disease. Directions for future research are recommended. PMID:18186549

Determinants of personal and household hygiene among college students in New York City, 2011  

PubMed Central

Background Although several studies have characterized the hygiene habits of college students, few have assessed the determinants underlying such behaviors. Objectives Our study sought to describe students' knowledge, practices, and beliefs about hygiene and determine whether there is an association between reported behaviors and frequency of illness. Methods A sample of 299 undergraduate students completed a questionnaire assessing demographics, personal and household hygiene behaviors, beliefs and knowledge about hygiene, and general health status. Results Variation in reported hygiene habits was noted across several demographic factors. Women reported “always” washing their hands after using the toilet (87.1%) more than men (65.3%, P = .001). Similarly, freshmen reported such behavior (80.4%) more than sophomores (71.9%), juniors (67.7%), or seniors (50%, P = .011). Whereas 96.6% of participants thought that handwashing was either “very important” or “somewhat important” for preventing disease, smaller proportions thought it could prevent upper respiratory infections (85.1%) or gastroenteritis (48.3%), specifically. There was no significant relationship between reported behaviors and self-reported health status. Conclusion The hygiene habits of college students may be motivated by perceptions of socially acceptable behavior rather than scientific knowledge. Interventions targeting the social norms of incoming and continuing students may be effective in improving hygiene determinants and ultimately hygiene practices. PMID:22464037

Purpose To investigate caregiver beliefs and behaviors as key issues in the initiation of home oral hygiene routines. Oral hygiene helps reduce the prevalence of early childhood caries, which is disproportionately high among Mexican-American children. Methods Interviews were conducted with a convenience sample of 48 Mexican-American mothers of young children in a low income, urban neighborhood. Interviews were digitally recorded, translated, transcribed, coded and analyzed using standard qualitative procedures. Results The average age of tooth brushing initiation was 1.8±0.8 years; only a small proportion of parents (13%) initiated oral hygiene in accord with American Dental Association (ADA) recommendations. Mothers initiated 2 forms of oral hygiene: infant oral hygiene and regular tooth brushing. For the 48% of children who participated in infant oral hygiene, mothers were prompted by pediatrician and social service (WIC) professionals. For regular tooth brushing initiation, a set of maternal beliefs exist about when this oral hygiene practice becomes necessary for children. Beliefs are mainly based on a child’s dental maturity, interest, capacity and age/size. Conclusions Most (87%) of the urban Mexican-American mothers in the study do not initiate oral hygiene practices in compliance with ADA recommendations. These findings have implications for educational messages. PMID:19947134

Estimating the Burden of Disease from Water, Sanitation, and Hygiene at a Global Level  

Microsoft Academic Search

We estimated the disease burden from water, sanitation, and hygiene at the global level taking into account various disease outcomes, principally diarrheal diseases. The disability-adjusted life year (DALY) combines the burden from death and disability in a single index and permits the comparison of the burden from water, sanitation, and hygiene with the burden from other risk factors or diseases.

The effect of leadership on hand hygiene: assessing hand hygiene adherence prior to patient contact in 2 infectious disease units in Tuscany.  


We assessed hand hygiene adherence in 2 infectious disease units. In one unit, adherence declined slightly from year 1 (84.2%) to year 4 (71.0%) after a multimodal intervention but remained much higher than before intervention. Adherence dropped in the second unit after a loss of leadership (from 50.7% to 5.7%). Strong leadership presence may improve hand hygiene adherence. PMID:24521600

Reactivity in rapidly collected hygiene and toilet spot check measurements: a cautionary note for longitudinal studies.  


Discreet collection of spot check observations to measure household hygiene conditions is a common measurement technique in epidemiologic studies of hygiene in low-income countries. The objective of this study was to determine whether the collection of spot check observations in longitudinal studies could itself induce reactivity (i.e., change participant behavior). We analyzed data from a 12-month prospective cohort study in rural Tamil Nadu, India that was conducted in the absence of any hygiene or toilet promotion activities. Our data included hygiene and toilet spot checks from 10,427 household visits. We found substantial evidence of participant reactivity to spot check observations of hygiene practices that were easy to modify on short notice. For example, soap observed at the household's primary handwashing location increased from 49% at enrollment to 81% by the fourth visit and remained at or above 77% for the remainder of the study.

Comments on "Implications of Hormesis for Industrial Hygiene".  


Although demonstrated evidence for hormesis of an agent could be important in setting occupational exposure limits (OELs) for industrial hygiene, several practical problems may limit the utility of toxicologic testing for hormesis. This commentary responds to the lead article of this section, in which Jayjock and Lewis propose using the results of tests for hormesis to guide the establishment of OELs. The principal difficulties may include: a different mechanism or even a different effect leading to the conclusion of hormesis; distinction between a threshold for a health effect and a crossover point in the dose response relationship; estimation of threshold or crossover point from limited test data and estimation of slope at this point; sensitivity of tests for hormesis; and cost of testing. Nevertheless, the proposals of Jayjock and Lewis have considerable merit, and exploratory testing could be useful. PMID:15497238

[Hygiene, diet and medicine in Arabic agricultural calendars].  


The author studied nine arab agricultural calendars placed at intervals between the "Kitab al Azmina" or the "book of seasons" by Jean Mésué (9th c.) and a tunisian calendar of the 19th c. of andalusian origin (?). There is a clear relationship between these different calendars, all of them issued from an archetype lost to-day, which would have been a mixture of basic principles and traditions of different origins. One could no longer identify to-day with certainty but one could discern its preislamic tradition (the calendar system of the "anwa") babylonian tradition (the predictions extracted from astronomic, meteorologic or geologic events) and a greek tradition (the influence of the humoral theory). In matter of dietetic, these calendars real authentic almanachs do nothing but reproduce the hippocratic prescriptions. In matter of hygiene, they specify seasons for physical exercices, both as well as the perfumes to make use of. ... PMID:11625221

[Intervention to improve hand hygiene compliance in Catalonia, Spain].  


Hand hygiene (HM) is the single most important measure and effective in reducing the risk of Healthcare acquired infections (IRAS). Although HM is an effective, simple and cheap measure, it is usual to find results of low compliance among health professionals. The main objective of this strategy has been to give new force to the promotion of HM in hospitals and educate professionals about the importance of this single action. The strategy was planned as a multicenter intervention study to promote HM in health centers of Catalonia in 2009-2010. The intervention is based on 4 main areas: a survey of barriers and facilitators, distribution of graphic material, training at different levels and measure of quality indicators. With this strategy a total of 57% of the number of acute beds in the concerted public and private network of hospitals were reached. The survey revealed that training was perceived as the main facilitator of the HM action. 15,376 professionals registered to the on-line training. The overall compliance with HM indications (based on "five moments for HM") was 56.45% in the acute areas. The campaigns and programs to promote HM carried out in the last four years in Catalonia has helped to achieve an increasing number of hospitals associated to the strategy of the Alliance for Patient Safety in Catalonia. The on-line curse acceptance was very high and seems a powerful tool to improve hand hygiene knowledge and compliance among health professionals. The compliance of HM seems to increase in the hospitals of Catalonia evaluated. PMID:25128358

Effects of feminine hygiene products on the vaginal mucosal biome  

PubMed Central

Background Over-the-counter (OTC) feminine hygiene products come with little warning about possible side effects. This study evaluates in-vitro their effects on Lactobacillus crispatus, which is dominant in the normal vaginal microbiota and helps maintain a healthy mucosal barrier essential for normal reproductive function and prevention of sexually transmitted infections and gynecologic cancer. Methods A feminine moisturizer (Vagisil), personal lubricant, and douche were purchased OTC. A topical spermicide (nonoxynol-9) known to alter the vaginal immune barrier was used as a control. L. crispatus was incubated with each product for 2 and 24h and then seeded on agar for colony forming units (CFU). Human vaginal epithelial cells were exposed to products in the presence or absence of L. crispatus for 24h, followed by epithelium-associated CFU enumeration. Interleukin-8 was immunoassayed and ANOVA was used for statistical evaluation. Results Nonoxynol-9 and Vagisil suppressed Lactobacillus growth at 2h and killed all bacteria at 24h. The lubricant decreased bacterial growth insignificantly at 2h but killed all at 24h. The douche did not have a significant effect. At full strength, all products suppressed epithelial viability and all, except the douche, suppressed epithelial-associated CFU. When applied at non-toxic dose in the absence of bacteria, the douche and moisturizer induced an increase of IL-8, suggesting a potential to initiate inflammatory reaction. In the presence of L. crispatus, the proinflammatory effects of the douche and moisturizer were countered, and IL-8 production was inhibited in the presence of the other products. Conclusion Some OTC vaginal products may be harmful to L. crispatus and alter the vaginal immune environment. Illustrated through these results, L. crispatus is essential in the preservation of the function of vaginal epithelial cells in the presence of some feminine hygiene products. More research should be invested toward these products before they are placed on the market. PMID:24009546

Enteroviruses, hygiene and type 1 diabetes: toward a preventive vaccine.  


Enteroviruses and humans have long co-existed. Although recognized in ancient times, poliomyelitis and type 1 diabetes (T1D) were exceptionally rare and not epidemic, due in large part to poor sanitation and personal hygiene which resulted in repeated exposure to fecal-oral transmitted viruses and other infectious agents and viruses and the generation of a broad protective immunity. As a function of a growing acceptance of the benefits of hygienic practices and microbiologically clean(er) water supplies, the likelihood of exposure to diverse infectious agents and viruses declined. The effort to vaccinate against poliomyelitis demonstrated that enteroviral diseases are preventable by vaccination and led to understanding how to successfully attenuate enteroviruses. Type 1 diabetes onset has been convincingly linked to infection by numerous enteroviruses including the group B coxsackieviruses (CVB), while studies of CVB infections in NOD mice have demonstrated not only a clear link between disease onset but an ability to reduce the incidence of T1D as well: CVB infections can suppress naturally occurring autoimmune T1D. We propose here that if we can harness and develop the capacity to use attenuated enteroviral strains to induce regulatory T cell populations in the host through vaccination, then a vaccine could be considered that should function to protect against both autoimmune as well as virus-triggered T1D. Such a vaccine would not only specifically protect from certain enterovirus types but more importantly, also reset the organism's regulatory rheostat making the further development of pathogenic autoimmunity less likely.

Overview of the Development of the Temporary Sleep Station Hygiene Liner Aboard the International Space Station  

NASA Technical Reports Server (NTRS)

Since the beginning of manned operations aboard the International Space Station (ISS), the crew had performed hygiene activities within the aisle way (the habitable volume, not including the sleep areas) of the ISS. The Crew used wet towels, re-hydrated body soap, and "no-rinse" shampoo to cleanse themselves amongst the stowage and systems hardware, referred to as "racks", even without a designated area to dry the wet items. Performing hygiene in this manner became an accepted method; no isolated location was available to the Crew. After several years of hygiene operations, some of the fabric-covered racks began to grow biological material (generically described as mold) and soon became a Crew health concern. Hygiene has one of the strongest impacts on Crew morale, and mandating changes to the Crew routine would have been met with strong resistance. The answer to the conundrum was to develop a liner to be placed within the Temporary Sleep Station (TeSS), one of the Crew s sleeping racks. This liner provided the Crew a means to perform hygiene activities within a private, enclosed area that also significantly decreased the potential to grow mold. This paper will describe the development of the TeSS Hygiene Liner, its impacts on the ISS and Crew, as well as its contribution to hygiene activities used in space today.

Food porn.  


Since the term first appeared, food porn has typically referred to watching others cook on television or gazing at unattainable dishes in glossy magazines without actually cooking oneself. This forum seeks to revisit this notion of food porn that is mostly taken for granted in both popular and scholarly literature. It offers a brief perspective of the appearance and use of the term food porn to examine how it came to be a term used mostly by commentators rather than by people actively engaged in the world of cooking. Practitioners (chefs and a food television producer) and academics address whether or not food porn exists, what shape it might take, what purpose it might serve, and/or what usefulness it might have, showing that these contentious issues are more complex than the ease with which the term is used might let on.

Bacterial contamination of the hands of food handlers as indicator of hand washing efficacy in some convenient food industries in South Africa  

PubMed Central

Background and Objectives: Hands of ready-to-eat food service employees have been shown to be vectors in the spread of foodborne disease, mainly because of poor personal hygiene and accounting for approximately 97% of food borne illnesses in food service establishments and homes. Our objective was to evaluate the efficacy of hand washing practices and sanitation before commencing work among food handlers in the convenient food industry in Gauteng, South Africa. Methods: A total of 230 samples were collected, involving 100% of the food handlers, in 8 selected convenient food outlets with their main focus on preparing ready-to-eat foods. The workers’ cleaned and disinfected dominant hands were sampled for Total Plate Count (TPC), Staphylococcus aureus and Escherichia coli. Bacteria were isolated and counted using standard methods. Results: The highest bacterial count from the hand samples was 7.4 x 103 and the lowest showed no detectable growth. Although hands with a count of 0 were found in all of the plants, the results indicated that all the plants exceeded the legal limit for food surfaces or hands of < 100 when the average bacterial counts on hands were compared. Sixty percent of the TPC analysed exceeded the legal limit and only 18% of the food handlers had no bacteria detectable on their hands. One sample tested positive for E. coli and S. aureus could not be detected on the hands of any of the food handlers. Conclusion: The study revealed that hand hygiene is unsatisfactory and may have serious implications for public health due to contamination of food from food handlers’ hands. This therefore underlined the importance of further training to improve food handlers’ knowledge of good hand washing practices. PMID:25097511

Action Products commercialized this technique, concentrating on snack food including the first freeze-dried ice cream. The foods are cooked, quickly frozen and then slowly heated in a vacuum chamber to remove the ice crystals formed by the freezing process. The final product retains 98 percent of its nutrition and weighs only 20 percent of its original weight. Action snacks are sold at museums, NASA facilities and are exported to a number of foreign countries. Sales run to several million dollars annually.



Incidence of bacteria of public health interest carried by cockroaches in different food-related environments.  


The aim of this study was to determine the incidence of bacteria of public health interest transmitted by cockroaches in different food-related environments. From April to November, cockroaches were trapped in 11 buildings in different urban areas of Western Andalusia (Spain): three hotels, four grocery stores, a catering establishment, a food-industry plant, a health center, and a care home. The presence of a number of bacterial species, including Salmonella, in these food-related environments was confirmed; these species included microorganisms listed in European Union regulations, such as Salmonella spp., Enterobacter sakazakii (Cronobacter spp.), and Escherichia coli. A wide variety of species were isolated, some belonging to different genera that have a significant impact on public health and hygiene, such as Enterobacter and Klebsiella. To ensure adequate elimination of these microorganisms in food-related environments, the control of vectors such as Blattella germanica, Periplaneta americana, and Blatta orientalis, together with a thorough review of hygiene strategies, appears to be fundamental. It is clearly essential to compare the results of hygiene regulations implemented in food-related environments. PMID:23270179

MediHandTrace ®: a tool for measuring and understanding hand hygiene adherence.  


The proper implementation of hand hygiene at key moments during patient care is the most important means of preventing healthcare-associated infection. Although there are many programmes aimed at enhancing hand hygiene, the compliance of healthcare workers (HCWs) remains incredibly low. One limiting factor is the lack of standardized measures and reports of hand hygiene opportunities. Direct observational audits have reported the weaknesses in this field. We report here a radiofrequency identification-based real-time automated continuous recording system (MediHandTrace(®)) that permits the tracking of hand hygiene opportunities and the disinfection compliance of HCWs that we evaluated against video recordings as being accurate (99.02%), sensitive (95.65%) and specific (100%). The system can also provide information that is useful to understand HCW non-compliance and will allow the evaluation of future intervention studies. PMID:24261513

Hand hygiene instruction decreases illness-related absenteeism in elementary schools: a prospective cohort study  

PubMed Central

Background Illness-related absences have been shown to lead to negative educational and economic outcomes. Both hand washing and hand sanitizer interventions have been shown to be effective in reducing illness-related absences. However, while the importance of hand hygiene in schools is clear, the role of instruction in use is less obvious. The purpose of this study was to compare absenteeism rates among elementary students given access to hand hygiene facilities versus students given both access and short repetitive instruction in use, particularly during influenza season when illness-related absences are at a peak. Methods A hand hygiene intervention was implemented from October to May during the 2009/2010 academic year, including peak flu season, in two Chicago Public Elementary Schools among students grades pre-kindergarten to eighth grade (ages 4–14). Classrooms were systematically assigned to an intervention or control group by grade (cluster design). Hand hygiene facilities (sanitizer and soap) were made available to all students. Students in the intervention group also received short repetitive instruction in hand hygiene every 2 months. Only absences as a result of respiratory or gastrointestinal illness were used to establish illness-related absenteeism rates. Percent absent days were calculated and bivariate analyses were performed to compare percent absent days among students given access to hand hygiene facilities versus students given both access and instruction. Prior to the intervention, teachers’ perceptions of students’ hand hygiene were also evaluated. Teacher perceptions were analysed to describe attitudes and beliefs. Results Data were collected and analysed for 773 students reporting 1,886 absences during the study period (1.73% of total school days). Both the percent total absent days and percent illness-related absent days were significantly lower in the group receiving short instruction during flu season (P?=?0.002, P?hygiene is not performed properly among students and reported time constraints as a barrier to frequent hand washing. Conclusions Adding hand hygiene instruction to existing hand hygiene practices improved attendance at public elementary schools during the flu season. Standardized and brief repetitive instruction in hand hygiene holds potential to significantly reduce absenteeism. PMID:22587432



Prevalence of the main food-borne pathogens in retail food under the national food surveillance system in Japan.  


The National Food Surveillance System in Japan was formed in 1998 to monitor the contamination of retail foods with bacterial pathogens. Approximately 2000-3000 samples were tested annually, and the data from food categories that had more than 400 samples collected during 1998-2008 were analysed. With regard to meat, the frequency of positive samples for Salmonella in chicken for raw consumption and ground chicken was 12.7% and 33.5%, respectively. Moreover, Shiga toxin-producing Escherichia coli (STEC) O157 was found in ground meat, organ meat and processed meat, although at a low frequency (0.1%). The prevalence of Campylobacter jejuni/coli was 13.3% and 20.9% in chicken for raw consumption and ground chicken, respectively. In vegetables and fruit, Salmonella was detected in cucumber, lettuce, sprout and tomato samples at a frequency of around 0.1-0.2%. With regard to seafood, Salmonella was found in 0.5% of oysters for raw consumption. Seafood was not contaminated with STEC O157 or Shigella. Serotype Infantis was the most frequently detected serotype of Salmonella in seafood, followed by the serotypes Typhimurium, Schwarzengrund and Manhattan. In ground chicken, 72.2% of the strains were identified as the serotype Infantis. E. coli, as an indicator of food hygiene, was detected in all food categories. The results show the prevalence of the above-mentioned pathogens in the retail food supplied in Japan; further, they indicate that consumption of raw food carries the risk of contracting food-borne infections.

See one, do one, teach one: Hand hygiene attitudes among medical students, interns, and faculty.  


An anonymous, online survey of medical students, interns, and faculty at a university hospital was conducted in 2013 to examine self-reported adherence to hand hygiene opportunities. Variation in self-reported adherence ranged from frequencies of 60%-100%. Such variation suggests the need to direct education toward hand hygiene opportunities with lower reported rates of adherence, especially toward those opportunities that are difficult to monitor.

Hand Hygiene in Peritoneal Dialysis Patients: A Comparison of Two Techniques  

PubMed Central

? Introduction and Objectives: Hand hygiene is essential for preventing peritoneal dialysis (PD)-related infections. The present study compared the effectiveness of two hygiene techniques in reducing the number of colony-forming units (CFUs) on the hands of patients undergoing PD. ? Methods: In this controlled clinical trial, 22 participants enrolled in the same PD program underwent a two-hand evaluation for microbiologic flora. Participants participated in two treatments: a) simple hand hygiene plus antiseptic hand hygiene, in which the patients washed their hands with water and glycerin soap for 1 minute and then rubbed and dried their hands with 70% ethyl alcohol gel; and b) antiseptic hand hygiene, in which the patients rubbed their hands with 70% ethyl alcohol gel until fully dry. To sample distal finger surfaces, we asked the participants to touch sheep blood agar plates directly. ? Results: The CFU count for both hands was significantly higher in the regular hygiene group than in the gel-only group [69.0 (16.0 - 101.0) CFU vs 9.0 (2.2 - 55.5) CFU, p < 0.010]. Growth of coagulase-negative Staphylococcus colonies was significantly higher in right-hand cultures from the regular hygiene group than in those from the gel-only group [69.5 (26.25 - 101.0) CFU vs 9.5 (1.0 - 41.7) CFU; p < 0.050]. ? Conclusions: Among patients undergoing PD, using 70% ethyl alcohol gel to cleanse the hands may be more effective than following the regular hygiene recommendations in reducing bacterial populations.

Effectiveness of a training programme to improve hand hygiene compliance in primary healthcare  

PubMed Central

Background Hand hygiene is the most effective measure for preventing infections related to healthcare, and its impact on the reduction of these infections is estimated at 50%. Non-compliance has been highlighted in several studies in hospitals, although none have been carried out in primary healthcare. Main objective To evaluated the effect of a "Hand Hygiene for the reduction of healthcare-associated infections" training program for primary healthcare workers, measured by variation from correct hand hygiene compliance, according to regulatory and specific criteria, 6 months after the baseline, in the intervention group (group receiving a training program) and in the control group (a usual clinical practice). Secondary objectives -To describe knowledges, attitudes and behaviors as regards hand hygiene among the professionals, and their possible association with "professional burnout", stratifying the results by type of group (intervention and usual clinical practice). -To estimate the logistic regression model that best explains hand hygiene compliance. Methods/Design Experimental study of parallel groups, with a control group, and random assignment by Health Center. Area of study.- Health centers in north-eastern Madrid (Spain). Sample studied.- Healthcare workers (physicians, odontostomatologists, pediatricians, nurses, dental hygienists, midwife and nursing auxiliaries). Intervention.- A hand hygiene training program, including a theoretical-practical workshop, provision of alcohol-based solutions and a reminder strategy in the workplace. Other variables: sociodemographic and professional knowledges, attitudes, and behaviors with regard to hand hygiene. Statistical Analysis: descriptive and inferential, using multivariate methods (covariance analysis and logistic regression). Discussion This study will provide valuable information on the prevalence of hand hygiene non-compliance, and improve healthcare. PMID:20015368



Nursing the tropics: nurses as agents of imperial hygiene  

PubMed Central

Background Mrs Francis Piggott proposed the Colonial Nursing Association in 1895 as a means of supplying Britain's colonies and dominions with trained professional nurses, who would support the health of white colonists abroad. Over 8400 nurses were placed between 1896 and the Association's end in 1966. Despite the burgeoning of scholarship on gender and empire over the last few decades, there is still more research to be done examining nurses as professional, working women, who present a fascinating variation on the figure of the woman traveler. Methods This essay focuses on 1896–1927, exploring how nurses were prepared for their labor abroad and how these skills were challenged and adapted within a foreign environment. We contextualize this discussion with examples from literary tales of exploration and adventure and discourses of empire. Results/conclusions Though the sources of disease against which nurses fought changed during this period, we assert that the underlying role of the nurse continued the same: she was meant to use the tools of personal as well as public ‘hygiene’ to create both physical and cultural boundaries around her white patients and herself, setting colonists apart from their colonial setting.

[Environmental hygiene and comprehensive processing of copper sulphate ore].  


The modern comprehensive processing of copper-sulphate ores is based on using the fire, chemical and combined fire-and-hydrometallurgy processes. The existing schemes of comprehensive ore processing do not provide for a total utilization of the metallurgical cycles wastes due to the inherent technological and design shortcomings; besides, they are a source of environmental pollution. Contamination of the atmospheric air with discharge elements has unfavorable effects on the health condition of population; it worsens the natural body resistance and contributes (through the induction of chromosome aberrations) to a higher general morbidity and mortality due to malignant neoplasms. Health-improve measures are supported by modern achievements in the sphere of copper-sulphate ore processing technologies--they ensure the hygienic and ecological rational management and usage at all stages of the processing of raw materials and secondary products. Institutions of the territorial medical-and-ecological monitoring are the corner stones for ecological safety of persons residing in areas of comprehensive copper-and-sulphate ore processing.

Analysis of different communication channels for promoting hygiene behaviour.  


A hygiene intervention study reduced diarrhoeal disease transmission in rural northeast Thailand by promoting hand-washing and dish-washing behaviour. Most of the target audience did not recognize a connection between these behaviours and diarrhoeal disease, and therefore a social marketing approach was used to develop a campaign promoting behaviours through a variety of communication channels keeping messages simple and in terms understood by the community. Overall, there was a strong correlation between the number of communication channels remembered by respondents and their knowledge score, with passive channels of printed media such as stickers, posters and leaflets associated with significantly higher scores than other channels. However, the same did not hold true for improvement in actual behaviour and only 'school children' were associated with significantly less fingertip contamination. In-depth interviews with conformers and non-conformers suggested that although most knew the intervention messages well enough, the importance they attached to them differed markedly. Thus dissemination of message knowledge was not consistent with the process of dissemination of actual practice. Where a strong sense of community spirit existed, friends, relatives and neighbours were more likely to discuss intervention activities with each other. PMID:10510071

Developing dental hygiene students as future leaders in legislative advocacy.  


The purpose of this investigation was to determine the effect of a legislative advocacy project on the knowledge, values, and actions of dental hygiene students enrolled in a leadership course. A quasi-experimental design was employed with a convenience sample of twenty-one undergraduate and seventeen graduate students. The data collection instrument was designed by the authors with three scales (knowledge, values, and actions), a section on barriers to future advocacy actions, and two open-ended questions. Content validity of the instrument was established before it was administered with an online survey tool. Students scored their pre-project and post-project status on the three scales. Cronbach's alphas revealed internal consistency of the three scales at 0.95 or higher. Pre-project scores and post-project scores were analyzed by parametric tests and confirmed using nonparametric tests. Knowledge, values, and actions statements were statistically significant; however, actions were rated the lowest. Multiple barriers for future advocacy actions were identified. Implementation of a legislative advocacy project in an undergraduate and graduate leadership course can positively influence the development of knowledge, values, and actions; however, mentorship in the professional association is needed after graduation to continue the development of future leaders.

Industrial hygiene aspects of underground oil shale mining  

SciTech Connect

Health hazards associated with underground oil shale mining are summarized in this report. Commercial oil shale mining will be conducted on a very large scale. Conventional mining techniques of drilling, blasting, mucking, loading, scaling, and roof bolting will be employed. Room-and-pillar mining will be utilized in most mines, but mining in support of MIS retorting may also be conducted. Potential health hazards to miners may include exposure to oil shale dusts, diesel exhaust, blasting products, gases released from the oil shale or mine water, noise and vibration, and poor environmental conditions. Mining in support of MIS retorting may in addition include potential exposure to oil shale retort offgases and retort liquid products. Based upon the very limited industrial hygiene surveys and sampling in experimental oil shale mines, it does not appear that oil shale mining will result in special or unique health hazards. Further animal toxicity testing data could result in reassessment if findings are unusual. Sufficient information is available to indicate that controls for dust will be required in most mining activities, ventilation will be necessary to carry away gases and vapors from blasting and diesel equipment, and a combination of engineering controls and personal protection will likely be required for control of noise. Recommendations for future research are included.

[Hygiene, dietetics and medicine in arab agricultural calendars].  


The author studied nine arab agricultural calendars placed at intervals between the Kitab al-Azmina or the Book of seasons by Jean Mésué (IXth c.) and a tunisian calendar of the XIXth c. of andalusian origin (?). There is a clear relationship between these different calendars, all of them issued from an archetype lost today, which would have been a mixture of basic principles and traditions of different origins. One could no longer identify today with certainty but one could discern its preislamic tradition (the calendar system of the anwâ'), babylonian tradition (the predictions extracted from astronomic, meteorologic or geologic events) and a greek tradition (the influence of the humoral theory). In matter of dietetic, these calendars real authentic almanachs do nothing but reproduce the hippocratic prescriptions. In matter of hygiene, they specify seasons for physical exercices, bath as well as the perfumes to make use of. Otherwise these almanachs mention the most usual affections and the liabale means to cure, or better, to prevent them. Are recommanded differents electuaries including the theriac, trochics, eyewashes and other medications. PMID:11625294

Hygienic quality of faeces treated in urine diverting vermicomposting toilets.  


On-site sanitation solutions have gained much interest in recent years. One such solution is the urine diverting vermicomposting toilet (UDVT). This study evaluated the hygienic quality of the composted material in six UDVTs in operation in France. Samples were taken from three sampling positions in each toilet, with increasing distance from the fresh material. The concentration of Salmonella spp., Enterococcus spp., thermotolarent coliforms and coliphages were analysed and plotted against a number of variables. The variables found to have the greatest impact was the pH (for Enterococcus spp. and thermotolarent coliforms (TTC)) and time since last maintenance (coliphages). The pH was found to correlate with the material maturity. The current practise of maintenance can cause recontamination of the stabilised material and increase the risk of regrowth of pathogenic microorganisms. A modification in the maintenance procedure, in which a fourth maturation point is introduced, would eliminate this risk. UDVTs were found to be a good on-site sanitation option as the maintenance requirement is small and the system effectively reduced odour and concentration of pathogen and indicator organisms in human waste while keeping the accumulation of material down to a minimum. If the vermicompost is to be used for crops consumed raw, an additional sanitisation step is recommended. PMID:23932466

Oral hygiene care in the pediatric intensive care unit: practice recommendations.  


Oral hygiene significantly affects children's well being. It is an integral part of intensive and critical care nursing because intubated and ventilated children in the Pediatric Intensive Care Unit (PICU) are dependent on the health care team to tend to their everyday basic needs. Fourteen articles were identified as being relevant to pediatric oral care in the PICU. These articles were subsequently appraised, and an oral hygiene in the PICU guideline was developed. Research highlighted the relationship between poor oral hygiene in the intensive care unit (ICU) and an increase in dental plaque accumulation, bacterial colonization of the oropharynx, and higher nosocomial infection rates, particularly ventilator-associated pneumonia. Research and a local, informal audit found the provision of oral hygiene care to PICU children varied widely and was often inadequate. Children in the PICU need their mouths regularly assessed and cleaned. Maintaining consistent, regular, and standardized oral hygiene practices in the PICU will also set an example for children and their families, encouraging and teaching them about the life-long importance of oral hygiene.

Knowledge of Oral Hygiene among Hemophilic Patients Referred to Iranian Hemophilia Society  

PubMed Central

Background and aims Hemophilic patients are faced with poor oral hygiene due to concerns about their dental care. The present study assessed the knowledge of hemophilic patients about oral hygiene and the effect of oral hygiene instruction in patients referred to Iranian Hemophilia Society. Materials and methods This cross-sectional study was carried out on 30 hemophilic patients randomly selected from volunteer patients referred to Iran Hemophilia Center. The study was performed by means of a questionnaire submitted to subjects before and after the instructional brochure submission. The questionnaire included demographic data and items regarding hemophilia and oral hygiene. Data was analyzed with McNemar test and paired t-test. Results The mean age of the patients was 21 years; 27 (90%) were males and 3 ones (10%) were females. They were mostly A hemophilia infected. Most patients enjoyed fair knowledge of oral hygiene. Changes in knowledge after reading the bro-chure were significant regarding the appropriate time to replace the toothbrush (P < 0.01), necessary visits for tooth examina-tions (P < 0.04), adjunctive methods of caries prevention (P < 0.001) and factors related to bleeding (P < 0.01); other factors improved slightly without significant changes. Conclusion The knowledge of hemophilic patients was fair regarding oral hygiene while some relevant factors improved after instructions. However, more instruction is needed in order to attain more improvement in some behaviors. PMID:23230484

Irradiation as a cold pasteurization process of food.  


A number of emerging pathogenic microorganisms and parasites in food, the wide publicity of outbreaks of foodborne diseases and the increasing number of immuno-compromised population have resulted in a need to develop proper strategies and technologies to protect health of consumers. Regulations in most countries which are promulgated to ensure safety of foods, are not properly enforced to protect consumers' health especially with regard to food of animal origin. While regulations are in place and properly enforced for liquid foods such as milk or fruit juices, more solid foods especially those of animal origin, e.g. poultry, meat and seafood, which are often contaminated by pathogenic microorganisms and parasites, are not similarly regulated. The number of incidences of foodborne diseases can the subsequent economic impact to the society can be enormous. Recently, an increasing number of national and international organizations have recognised the use of irradiation as a method to ensure hygienic quality of more solid food of animal origin in the same manner as thermal pasteurization does for liquid foods. The effectiveness of irradiation as a cold pasteurization method to control foodborne disease caused by pathogenic microorganisms and parasites, especially in food to be consumed raw or partially processed, is established. Its role in overcoming trade barriers of food of animal origin based on the principle of the Agreement on the Application of Sanitary and Phytosanitary Measures, adopted during the GATT Uruguay Round will be discussed.

The FINUT healthy lifestyles guide: Beyond the food pyramid.  


The WHO has proposed that health be promoted and protected through the development of an environment that enables sustainable actions at individual, community, national, and global levels. Indeed, food-based dietary guidelines, i.e., food pyramids, have been developed in numerous countries to disseminate nutritional information to the general population. However, wider recommendations are needed, with information on an active healthy lifestyle, not just healthy eating. The objective of the present work is to propose a three-dimensional pyramid as a new strategy for promoting adequate nutrition and active healthy lifestyles in a sustainable way. Indeed, the Iberoamerican Nutrition Foundation (FINUT) pyramid of healthy lifestyles has been designed as a tetrahedron, with its 3 lateral faces corresponding to the facets of food and nutrition, physical activity and rest, and education and hygiene. Each lateral face is divided into 2 triangles. These faces show the following: 1) food-based guidelines and healthy eating habits as related to a sustainable environment; 2) recommendations for rest and physical activity and educational, social, and cultural issues; and 3) selected hygiene and educational guidelines that, in conjunction with the other 2 faces, would contribute to better health for people in a sustainable planet. The new FINUT pyramid is addressed to the general population of all ages and should serve as a guide for living a healthy lifestyle within a defined social and cultural context. It includes an environmental and sustainability dimension providing measures that should contribute to the prevention of noncommunicable chronic diseases. PMID:24829489

Can Control Banding be better than traditional Industrial Hygiene?  

SciTech Connect

The answer to this question should be 'no' if you can afford it and 'yes' if you cannot. However, Control Banding (CB) is proving itself in areas with uncertainties. This could be either a lack of knowledge--as with nanomaterials or when lacking an OEL--or with the lack or expertise, as can be seen with SMEs and in Economically Developing Countries (EDCs). Over 90% of the world's workers do not have access to occupational safety, health, and hygiene (OSHH) professionals and traditional quantitative risk assessment methods to achieve prevention from acquiring work-related illness and injury. Although risk factors for work-related illness and disease are well known, until the recent growth of CB there had yet to be designed and implemented a comprehensive OSHH process that focuses on achieving minimization of these occupational risk factors for the vast majority of the global workforce. This problem exists for three primary reasons: (1) There are not a sufficient number of trained and qualified OSHH professionals worldwide to attempt to offer comparable levels of traditional services necessary to achieve prevention; (2) The vast majority of OSHH professionals, and the funds to afford their conventional approaches, are concentrated in Developed Countries, such as those in the EU and the US, whereas the greatest need for work-related disease, illness, and injury prevention lies within EDCs; and (3) Even within Developed Countries, the funding to acquire the services of OSHH professionals sits primarily within the largest of industries and governmental institutions. This problem renders a void of occupational risk management for the professions and trades within EDCs and similarly the SMEs within even the richest of Developed Countries. Further, conventional means to achieve such prevention rely heavily on exposure assessment sampling strategies that, although proven successful, are cost-prohibitive in these arenas.

Protective glove use and hygiene habits modify the associations of specific pesticides with Parkinson's disease.  


Pesticides have been associated with Parkinson's disease (PD), and protective gloves and workplace hygiene can reduce pesticide exposure. We assessed whether use of gloves and workplace hygiene modified associations between pesticides and PD. The Farming and Movement Evaluation (FAME) study is a nested case-control study within the Agricultural Health Study. Use of protective gloves, other PPE, and hygiene practices were determined by questionnaire (69 cases and 237 controls were included). We considered interactions of gloves and hygiene with ever-use of pesticides for all pesticides with ?5 exposed and unexposed cases and controls in each glove-use stratum (paraquat, permethrin, rotenone, and trifluralin). 61% of respondents consistently used protective gloves and 87% consistently used ?2 hygiene practices. Protective glove use modified the associations of paraquat and permethrin with PD: neither pesticide was associated with PD among protective glove users, while both pesticides were associated with PD among non-users (paraquat OR 3.9 [95% CI 1.3, 11.7], interaction p=0.15; permethrin OR 4.3 [95% CI 1.2, 15.6] interaction p=0.05). Rotenone was associated with PD regardless of glove use. Trifluralin was associated with PD among participants who used <2 hygiene practices (OR 5.5 [95% CI 1.1, 27.1]) but was not associated with PD among participants who used 2 or more practices (interaction p=0.02). Although sample size was limited in the FAME study, protective glove use and hygiene practices appeared to be important modifiers of the association between pesticides and PD and may reduce risk of PD associated with certain pesticides.

Clean Hands for Life: results of a large, multicentre, multifaceted, social marketing hand-hygiene campaign.  


A year-long multifaceted hand-hygiene campaign entitled Clean Hands for Life targeting individual, environmental and organisational factors that influence healthcare worker (HCW) hand-hygiene behaviour was implemented in 36 acute and long-term care facilities in Vancouver Coastal Health region. The campaign involved rotation of ten novel posters, two poster contests, and distribution of multiple promotional items. A social marketing approach was used to implement and monitor the effectiveness of the campaign. Evaluation included quality assurance surveys, staff surveys (baseline, mid- and post-campaign), and focus groups. A total of 141 poster contest submissions was received, 5452 staff surveys completed and 14 focus groups conducted. Overall knowledge of the importance of hand-hygiene and intention to clean hands was high at baseline. No significant differences were observed when mid- and post-campaign scores were compared to baseline. The majority (89.5%) of HCWs reported that they preferred soap and water over alcohol hand gel. A significant increase in the self-reported use of hand-hygiene products was observed particularly among HCWs not providing direct patient care. Barriers to hand-hygiene included inappropriate placement of sinks, traffic flow issues, inadequately stocked washrooms, workload and time constraints. Organisational support was visible throughout the campaign. The results showed that social marketing is an effective approach in engaging HCWs. Hand-hygiene campaigns that focus almost exclusively on increasing awareness among HCWs may not be as successful as multifaceted campaigns or campaigns that target identified barriers to hand-hygiene.

Challenges in Achieving Food Security in India  

PubMed Central

First Millennium Development Goal states the target of “Halving hunger by 2015”. Sadly, the recent statistics for India present a very gloomy picture. India currently has the largest number of undernourished people in the world and this is in spite of the fact that it has made substantial progress in health determinants over the past decades and ranks second worldwide in farm output. The causes of existing food insecurity can be better viewed under three concepts namely the: ‘traditional concept’ which includes factors such as unavailability of food and poor purchasing capacity; ‘socio-demographic concept’ which includes illiteracy, unemployment, overcrowding, poor environmental conditions and gender bias; ‘politico-developmental concept’ comprising of factors such as lack of intersectoral coordination and political will, poorly monitored nutritional programmes and inadequate public food distribution system. If the Millennium Development Goal is to be achieved by 2015, efforts to improve food and nutrition security have to increase considerably. Priority has to be assigned to agriculture and rural development along with promoting women empowerment, ensuring sustainable employment and improving environmental conditions (water, sanitation and hygiene). As the problem is multi-factorial, so the solution needs to be multi-sectoral. PMID:23113100

Behavior of Yersinia enterocolitica in Foods  

PubMed Central

Yersinia enterocolitica are ubiquitous, being isolated frequently from soil, water, animals, and a variety of foods. They comprise a biochemically heterogeneous group that can survive and grow at refrigeration temperatures. The ability to propagate at refrigeration temperatures is of considerable significance in food hygiene. Virulent strains of Yersinia invade mammalian cells such as HeLa cells in tissue culture. Two chromosomal genes, inv and ail, were identified for cell invasion of mammalian. The pathogen can cause diarrhoea, appendicitis and post-infection arthritis may occur in a small proportion of cases. The most common transmission route of pathogenic Y. enterocolitica is thought to be fecal-oral via contaminated food. Direct person-to-person contact is rare. Occasionally, pathogenic Y. enterocolitica has been detected in vegetables and environmental water; thus, vegetables and untreated water are also potential sources of human yersiniosis. However, the isolation rates of pathogenic Y. enterocolitica have been low, which may be due to the limited sensitivity of the detection methods. To identify other possible transmission vehicles, different food items should be studied more extensively. Many factors related to the epidemiology of Y. enterocolitica, such as sources, transmission routes, and predominating genotypes remain obscure because of the low sensitivity of detection methods.

Patient-as-observer approach: an alternative method for hand hygiene auditing in an ambulatory care setting.  


A survey pilot asked patients to observe the hand hygiene compliance of their health care providers. Patients returned 75.1% of the survey cards distributed, and the overall hand hygiene compliance was 96.8%. Survey results and patient commentary were used to motivate hand hygiene compliance. The patient-as-observer approach appeared to be a viable alternative for hand hygiene auditing in an ambulatory care setting because it educated, engaged, and empowered patients to play a more active role in their own health care.

Food safety management systems performance in African food processing companies: a review of deficiencies and possible improvement strategies.  


This study seeks to provide insight into current deficiencies in food safety management systems (FSMS) in African food-processing companies and to identify possible strategies for improvement so as to contribute to African countries' efforts to provide safe food to both local and international markets. This study found that most African food products had high microbiological and chemical contamination levels exceeding the set (legal) limits. Relative to industrialized countries, the study identified various deficiencies at government, sector/branch, retail and company levels which affect performance of FSMS in Africa. For instance, very few companies (except exporting and large companies) have implemented HACCP and ISO 22000:2005. Various measures were proposed to be taken at government (e.g. construction of risk-based legislative frameworks, strengthening of food safety authorities, recommend use of ISO 22000:2005, and consumers' food safety training), branch/sector (e.g. sector-specific guidelines and third-party certification), retail (develop stringent certification standards and impose product specifications) and company levels (improving hygiene, strict raw material control, production process efficacy, and enhancing monitoring systems, assurance activities and supportive administrative structures). By working on those four levels, FSMS of African food-processing companies could be better designed and tailored towards their production processes and specific needs to ensure food safety.

Reflective blogs in clinical education to promote critical thinking in dental hygiene students.  


One challenge facing dental hygiene, as well as dental, education is to identify clinical teaching strategies promoting critical thinking and clinical reasoning. These skills are crucial elements in the practice of dental hygiene. A two-group design (intervention, n=28, and control, n=30) assessed first-year dental hygiene students using pre-and post-Health Science Reasoning Test (HSRT) scores to evaluate the effect of reflective blogging on critical thinking skills. A reflective blog rubric, based on Mezirow's levels of reflection, determined if reflective blogging increased the level of reflection for dental hygiene students. The results suggest within this nonprobability sample that reflective blogging did not produce a significant change in students' HSRT scores (p>0.05). However, analyses of reflective blog rubric scores demonstrated statistically significant improvements (p<0.05) in students' levels of reflection. Furthermore, data analysis revealed a correlation (p<0.05) between HSRT subscale scores and the element of reflection scores for the intervention group. This study addressed needs of the dental and dental hygiene education community by examining the use of blogs, an emerging technology, as a tool for reflecting on clinical experiences and, in turn, for promoting critical thinking.

[Interventional Patient Hygiene Model. A critical reflection on basic nursing care in intensive care units].  


Interventional Patient Hygiene Model. A critical reflection on basic nursing care in intensive care units. Over the past 15 years, the model of medical and nursing care changed from being exclusively oriented to the diagnosis and treatment of acute illness, to the achievement of outcomes by preventing iatrogenic complications (Hospital Acquired Conditions). Nursing Sensitive Outcomes show as nursing is directly involved in the development and prevention of these complications. Many of these complications, including falls from the bed, use of restraints, urinary catheter associated urinary infections and intravascular catheter related sepsis, are related to basic nursing care. Ten years ago in critical care, a school of thought called get back to the basics, was started for the prevention of errors and risks associated with nursing. Most of these nursing practices involve hygiene and mobilization. On the basis of these reflections, Kathleen Vollman developed a model of nursing care in critical care area, defined Interventional Patient Hygiene (IPH). The IPH model provides a proactive plan of nursing interventions to strengthen the patients' through the Evidence-Based Nursing Care. The components of the model include interventions of oral hygiene, mobilization, dressing changes, urinary catheter care, management of incontinence and bed bath, hand hygiene and skin antisepsis. The implementation of IPH model follows the steps of Deming cycle, and requires a deep reflection on the priorities of nursing care in ICU, as well as the effective teaching of the importance of the basic nursing to new generations of nurses.

What are school children in Europe being taught about hygiene and antibiotic use?  


e-Bug is a pan-European antibiotic and hygiene teaching resource that aims to reinforce awareness in school children of microbes, prudent antibiotic use, hygiene and the transmission of infection. Prior to the production of the resource, it was essential to examine the educational structure across each partner country and assess what school children were being taught on these topics. A questionnaire was devised for distribution to each European partner (Belgium, Czech Republic, Denmark, England, France, Greece, Italy, Poland, Portugal and Spain), exploring their educational structure and examining educational resources or campaigns currently available. From the data collected it was evident that the majority of European schools have structured hand hygiene practices in place from a young age. The curricula in all countries cover the topic of human health and hygiene, but limited information is provided on antibiotics and their prudent use. School educational resources that link to the national curriculum and implement National Advice to the Public campaigns in the classroom are limited. The Microbes en question mobile health education campaign in France is an example of a successful children's education campaign and an innovative programme. Evaluation of the impact of school education on attitude and change of behaviour is also limited throughout many European countries. Not enough is currently being done across Europe to educate school children on the importance of appropriate antibiotic use and antibiotic resistance. The data from this research were used to develop e-Bug, a European Union-funded antibiotic and hygiene teaching resource. PMID:21680582

The role and functionality of Veterinary Services in food safety throughout the food chain.  


Both national Veterinary Services and international standard-setting organisations have now embraced risk assessment as an essential tool for achieving their goals. Veterinarians have key roles in all aspects of the control of food-borne hazards of animal origin, but additional specialist skills are necessary for assessing, managing and communicating risk. Further, the deployment of Veterinary Services must reflect the multi-functional aspects of public and animal health activities. A generic risk management framework provides a systematic process whereby food safety standards and other measures are chosen and implemented on the basis of knowledge of risk and evaluation of other factors relevant to protecting human health and promoting non-discriminatory trade practices. In this context, a number of countries are exploring new administrative and structural arrangements for competent authorities. The traditional focus of veterinary involvement in food safety has been in meat hygiene at the level of the slaughterhouse. While this role continues, the emerging 'risk-based' approach to food control requires increased involvement in other segments of the meat food chain, as well as other areas such as production of milk and fish. This more extensive role requires a wider skill base and establishment of effective networks with a different range of stakeholders. PMID:17094715

Space shuttle food system summary, 1981-1986  

NASA Technical Reports Server (NTRS)

All food in the Space Shuttle food system was precooked and processed so it required no refrigeration and was either ready-to-eat or could be prepared for consumption by simply adding water and/or heating. A gun-type water dispenser and a portable, suitcase-type heater were used to support this food system during the first four missions. On STS-5, new rehydratable packages were introduced along with a needle-injection water dispenser that measured the water as it was dispensed into the packages. A modular galley was developed to facilitate the meal preparation process aboard the Space Shuttle. The galley initially flew on STS-9. A personal hygiene station, a hot or cold water dispenser, a convection oven, and meal assembly areas were included in the galley.

Survey of nasal carriage of Staphylococcus aureus and intestinal parasites among food handlers working at Gondar University, Northwest Ethiopia  

PubMed Central

Background Food borne disease are major health problems in developing countries like Ethiopia. Food handlers with poor personal hygiene working in food establishments could be potential sources of disease due to pathogenic organisms. However; information on disease prevalence among food handlers working in University of Gondar cafeterias are very scarce. The aim of this study is to assess the prevalence of nasal carriage of Staphylococcus aureus, their drug resistance pattern and prevalence of intestinal parasites among food handlers working in University of Gondar student’s cafeterias. Method A cross sectional study was conducted among food handlers working in University of Gondar student’s cafeterias. A pretested structured questionnaire was used for collecting data. Nasal swab and stool were investigated for S. aureus and intestinal parasites; respectively as per the standard of the laboratory methods. Results Among 200 food handlers, females comprised 171(85.5%). The majority (67.5%) of the food-handlers were young adults aged 18–39?years. One hundred ninety four (97%) of the food handlers were not certified as a food handler. Forty one (20.5%) food handlers were positive for nasal carriage of S. aureus, of these 4(9.8%) was resistant for methicilin. Giardia lamblia was the most prevalent parasites 22 (11%), followed by Ascaris lumbricoides 13(6.5%), Entamoeba histolytica 12 (6%), Strongyloides stercolaris (0.5), Taenia species 1(0.5%) and Schistosoma mansoni 1(0.5%). Conclusion The finding stressed that food handlers with different pathogenic micro organisms may pose significant risk on the consumers. Higher officials should implement food handler’s training on food safety, periodic medical checkup and continuous monitoring of personal hygiene of food handlers. PMID:23031414



Avicenna’s Educational Views with Emphasis on the Education of Hygiene and Wellness  

PubMed Central

Today, on the contrary of the last ten decades, the necessity of teaching hygienic issues, and caring the children’s health, is pretty obvious. Avicenna (10 AC), the famous Iranian physician and philosopher, scrutinized the health and hygiene with a deep insight to the matter. He considered the wellness not only as the recovery from the disease, but emphasized the maintenance of health by suggesting special points and instructions. In Islamic education, paying attention to cleanliness, health and physical strength is very important and considered as the intermediate goals for the achievement of “pure life”, which is the ultimate goal. Avicenna paid special attention to physical purity, health and wellness, and devoted the major parts of his book to them. The present article analyzes the Avicenna’s educational opinions, specially his viewpoints regarding hygiene and health in three stages of childhood, teenage years, and youth. PMID:24596865

Benefits of a 'dental hygiene chew' on the periodontal health of cats.  


A study was undertaken to determine the clinical efficacy of a chew designed to improve dental hygiene in the cat. The accumulation of dental deposits (plaque and calculus) and the effect on gingival inflammation were assessed in 15 client-owned cats while on two different regimens. In the first leg of the study, the cats were fed a nutritionally complete dry diet supplemented with one dental hygiene chew. In the second leg of the study, the same cats were fed only the nutritionally complete diet. This study demonstrated that the daily addition of the chew to the dry diet resulted in significantly less plaque and calculus accumulation on tooth surfaces. It was our experience that daily feeding of the chew helped maintain dental hygiene in cats; however, regular professional therapy is still indicated. PMID:10597159

Coming clean: the symbolic use of clinical hygiene in a hospital sterilising unit.  


The hospital Theatre Sterile Supplies Unit cleans and provides sterile instruments for use in operating theatres. The strict standards of cleanliness, based on scientific notions of clinical hygiene, are maintained at the everyday level by people such as ancillary workers, nurses and doctors organising their activities, movements and understandings according to known rules. Since clinical hygiene is related to advanced microbiological discoveries, an instrument cannot be judged sterile by the naked eye. The judgement is made on the basis of what is believed to be happening to the instrument (e.g. processes it goes through; places it has been). The paper, based on an empirical study, notes the conceptual relationship between primitive and western notions of hygiene, and examines the ways that rules are used in the everyday accomplishment of instrument sterilisation.

Social immunity in honeybees (Apis mellifera): transcriptome analysis of varroa-hygienic behaviour.  


Honeybees have evolved a social immunity consisting of the cooperation of individuals to decrease disease in the hive. We identified a set of genes involved in this social immunity by analysing the brain transcriptome of highly varroa-hygienic bees, who efficiently detect and remove brood infected with the Varroa destructor mite. The function of these candidate genes does not seem to support a higher olfactory sensitivity in hygienic bees, as previously hypothesized. However, comparing their genomic profile with those from other behaviours suggests a link with brood care and the highly varroa-hygienic Africanized honeybees. These results represent a first step toward the identification of genes involved in social immunity and thus provide first insights into the evolution of social immunity. PMID:21435061

Dishing the dirt on asthma: What we can learn from poor hygiene.  


Allergic asthma continues to represent a huge health burden worldwide and is largely treated by non-selective immunosuppressive drugs, which often prove ineffective. The hygiene hypothesis proposes that the increased incidence of allergy and asthma in Western countries observed in the last 50 years is due to environmental changes that include improved hygiene and a lack of infections. The immunological mechanisms that must underpin such an environmental impact on immune regulation remain to be defined, making it difficult to identify specific ways of preventing development of allergy and asthma in early life. In this article we will seek to review some of the pathways that might underlie the hygiene hypothesis in an attempt to provide targets for future asthma prevention. PMID:19707324

[Activities of the occupational hygiene section of the State Sanitary Inspection Service in 1992].  


The organizational and employment structures as well as activities of the occupational hygiene section of the sanitary and epidemiological services in Poland in 1992 are discussed. The information presented is based on special forms (Mz-50) and progress reports provided by individual units. Special emphasis is put on problems faced by these services in supervising placedu of employment. The need for regular training of occupational hygienists (public health managers) and improving qualifications of workers with secondary education employed in the area of occupational hygiene is stressed. An in-depth reform of occupational hygiene units is required as their present condition, as far as staff and equipment are concerned inables them to provide regular monitoring of harmful factors occurring in the occupational environment.

A microbiological evaluation of warm air hand driers with respect to hand hygiene and the washroom environment.  


A finger rinse technique for counting micro-organisms on hands showed no significant difference in the level of recovered micro-organisms following hand drying using either warm air or paper towels. Contact plate results appeared to reflect the degree of dampness of hands after drying rather than the actual numbers of micro-organisms on the hands. In laboratory tests, a reduction in airborne count of Pseudomonas aeruginosa and Staphylococcus aureus of between 40 and 75% was achieved from 600 readings comparing inlets and outlets of warm air hand driers. In washroom trials, the number of airborne micro-organisms was reduced by between 30 and 75%. Air emitted from the outlet of the driers contained significantly fewer micro-organisms than air entering the driers. Drying of hands with hand driers was no more likely to generate airborne micro-organisms than drying with paper towels. Levels of micro-organisms on external surfaces of hand driers were not significantly different to those on other washroom surfaces. This work shows that warm air hand driers, of the type used in this study, are a hygienic method of drying hands and therefore appropriate for use in both the healthcare and food industry.

India moves towards menstrual hygiene: subsidized sanitary napkins for rural adolescent girls-issues and challenges.  


The onset of menstruation is one of the most important physiological changes occurring among girls during the adolescent years. Menstruation heralds the onset of physiological maturity in girls. It becomes the part and parcel of their lives until menopause. Apart from personal importance, this phenomenon also has social significance. In India, menstruation is surrounded by myths and misconceptions with a long list of "do's" and "don'ts" for women. Hygiene-related practices of women during menstruation are of considerable importance, as it may increase vulnerability to Reproductive Tract Infections (RTI's). Poor menstrual hygiene is one of the major reasons for the high prevalence of RTIs in the country and contributes significantly to female morbidity. Most of the adolescent girls in villages use rags and old clothes during menstruation, increasing susceptibility to RTI's. Adolescents constitute one-fifths of India's population and yet their sexual health needs remain largely unaddressed in the national welfare programs. Poor menstrual hygiene in developing countries has been an insufficiently acknowledged problem. In June 2010, the Government of India proposed a new scheme towards menstrual hygiene by a provision of subsidized sanitary napkins to rural adolescent girls. But there are various other issues like awareness, availability and quality of napkins, regular supply, privacy, water supply, disposal of napkins, reproductive health education and family support which needs simultaneous attention for promotion of menstrual hygiene. The current article looks at the issue of menstrual hygiene not only from the health point of view, but also considers social and human rights values attached to it. PMID:21505773

Referring periodontal patients: clinical decision making by dental and dental hygiene students.  


Referral of periodontal patients requires development of a complex set of decision making skills. This study was conducted to determine criteria used by dental and dental hygiene students regarding the referral of periodontal patients for specialty care. Using mixed methods, a thirteen-item survey was developed to elicit the students' perceptions of their knowledge, confidence regarding managing patients, and clinical reasoning related to periodontal patients. The instrument was administered during the summer prior to (T1) and at the end of the students' final year (T2) of training. Seventy-nine dental students (81 percent of total class) and thirty dental hygiene students (83 percent of total class) completed T1. At T2, forty-two dental (44 percent of total class) and twenty-six dental hygiene students (87 percent of total class) completed the questionnaire. While 90 percent of dental and 96 percent of dental hygiene respondents reported a willingness to refer patients with active disease to specialists, only 40 percent of dental and 36 percent of dental hygiene respondents reported confidence in diagnosing, treating, and appropriately referring such patients. The students' ability to recognize critical disease and risk factors influencing referral was good; however, clinical application of that knowledge indicated a gap between knowledge and applied reasoning. The students' attitudes about the importance of periodontal disease and their perceived competence to identify critical disease risk factors were not significantly related (p>0.05) to correct clinical decisions in the case scenarios. The study concludes that dental and dental hygiene curricula should emphasize both the acquisition and application of knowledge regarding criteria for referral of periodontal patients. PMID:24609346

Dissemination of the CDC's Hand Hygiene Guideline and impact on infection rates  

PubMed Central

Background The diffusion of national evidence-based practice guidelines and their impact on patient outcomes often go unmeasured. Methods Our objectives were to (1) evaluate implementation and compliance with clinical practices recommended in the new Centers for Disease Control and Prevention (CDC) Hand Hygiene Guideline, (2) compare rates of health care-associated infections (HAI) before and after implementation of the Guideline recommendations, and (3) examine the patterns and correlates of changes in rates of HAI. We used pre- and post-Guideline implementation site visits and surveys in the setting of 40 US hospitals—members of the National Nosocomial Infections Surveillance System—and measured HAI rates 1 year before and after publication of the CDC Guideline and used direct observation of hand hygiene compliance and Guideline implementation scores. Results All study hospitals had changed their policies and procedures and provided products in compliance with Guideline recommendations; 89.8% of 1359 staff members surveyed anonymously reported that they were familiar with the Guideline. However, in 44.2% of the hospitals (19/40), there was no evidence of a multidisciplinary program to improve compliance. Hand hygiene rates remained low (mean, 56.6%). Rates of central line-associated bloodstream infections were significantly lower in hospitals with higher rates of hand hygiene (P < .001). No impact of Guideline implementation or hand hygiene compliance on other HAI rates was identified. Other factors occurring over time could affect rates of HAI. Observed hand hygiene compliance rates were likely to overestimate rates in actual practice. The study may have been of too short duration to detect the impact of a practice guideline. Conclusion Wide dissemination of this Guideline was not sufficient to change practice. Only some hospitals had initiated multidisciplinary programs; practice change is unlikely without such multidisciplinary efforts and explicit administrative support. PMID:18063132

[Health dictatorship, education and hygiene promotion in Revolutionary Mexico, 1917-1934].  


This work aims to study the so-called Mexican "health dictatorship", whose legal basis was established with the promulgation of the Political Constitution in 1917, but which maintained itself more as a discourse than as a practice. Instead of authoritarian politics, hygiene education and promotion were used as means of "regenerating" the Mexican people and leading the nation along the path of progress and civilization. This paper intends to show the importance given to hygiene campaign between 1917 and 1934 by the regime that emerged from the Mexican Revolution (1910-1917). PMID:17345657

Bacterial spoilers of food: Behavior, fitness and functional properties.  


Most food products are highly perishable as they constitute a rich nutrient source for microbial development. Among the microorganisms contaminating food, some present metabolic activities leading to spoilage. In addition to hygienic rules to reduce contamination, various treatments are applied during production and storage to avoid the growth of unwanted microbes. The nature and appearance of spoilage therefore depend on the physiological state of spoilers and on their ability to resist the processing/storage conditions and flourish on the food matrix. Spoilage also relies on the interactions between the microorganisms composing the ecosystems encountered in food. The recent rapid increase in publicly available bacterial genome sequences, as well as the access to high-throughput methods, should lead to a better understanding of spoiler behavior and to the possibility of decreasing food spoilage. This review lists the main bacterial species identified as food spoilers, their ability to develop during storage and/or processing, and the functions potentially involved in spoilage. We have also compiled an inventory of the available genome sequences of species encompassing spoilage strains. Combining in silico analysis of genome sequences with experimental data is proposed in order to understand and thus control the bacterial spoilage of food better. PMID:25481061

Revisiting mental hygiene: Josef Lundahl's interpretation of modern psychiatry in Sweden at the beginning of the twentieth century.  


The concept of mental hygiene is historically intertwined with eugenics and what it meant both ideologically and for the care of the mentally ill. A closer investigation of the concept and of the historical context shows that different interpretations existed simultaneously. The aim of this essay is to highlight the literary and scientific works of a Swedish psychiatrist, Josef Lundahl, an advocate of the mental hygiene concept. A close reading of his texts is used to provide an example of how the concept of mental hygiene was understood by a psychiatrist and practitioner of mental hygiene. The practice of child-care and out-patient care that Lundahl founded in Visby is far from what we now associate with mental hygiene in the past. PMID:24572796

Observational trial of safe food handling behavior during food preparation using the example of Campylobacter spp.  


Campylobacter infections are one of the most prominent worldwide food-related diseases. The primary cause of these infections is reported to be improper food handling, in particular cross-contamination during domestic preparation of raw chicken products. In the present study, food handling behaviors in Austria were surveyed and monitored, with special emphasis on Campylobacter cross-contamination. Forty participants (25 mothers or fathers with at least one child ?10 years of age and 15 elderly persons ?60 years of age) were observed during the preparation of a chicken salad (chicken slices plus lettuce, tomato, and cucumber) using a direct structured observational scoring system. The raw chicken carcasses and the vegetable part of the salad were analyzed for Campylobacter. A questionnaire concerning knowledge, attitudes, and interests related to food safety issues was filled out by the participants. Only 57% of formerly identified important hygiene measures were used by the participants. Deficits were found in effective hand washing after contact with raw chicken meat, but proper changing and cleaning of the cutting board was noted. Campylobacter was present in 80% of raw chicken carcasses, albeit the contamination rate was generally lower than the limit of quantification (10 CFU/g). In the vegetable part of the prepared product, no Campylobacter was found. This finding could be due to the rather low Campylobacter contamination rate in the raw materials and the participants' use of some important food handling behaviors to prevent cross-contamination. However, if the initial contamination had been higher, the monitored deficits in safe food handling could lead to quantifiable risks, as indicated in other published studies. The results of the observational trial and the questionnaire indicated knowledge gaps in the food safety sector, suggesting that further education of the population is needed to prevent the onset of foodborne diseases.

Bacteriological quality of foods and water sold by vendors and in restaurants in Nsukka, Enugu State, Nigeria: a comparative study of three microbiological methods.  


Bacterial count in prepared food or water is a key factor in assessing the quality and safety of food. It also reveals the level of hygiene adopted by food handlers in the course of preparation of such foods. This comparative study evaluated the bacteriological quality of food and water consumed in Nsukka, Enugu state, Nigeria, using three bacteria enumeration methods. Data obtained are assumed to reflect the level of personal and environmental hygiene in the study population. Ten types of foods--beans, yam, abacha, okpa, moimoi, pear, cassava foofoo, rice, agidi, and garri--and 10 water samples were evaluated for bacteriological quality, precisely determining the level of coliform contamination, using the most probable number (MPN), lactose fermentation count (LFC), and Escherichia coli count (ECC) methods. Bacterial counts differed significantly (p < 0.05) among the various food samples. However, this did not differ significantly in the three methods used for the enumeration of coliforms, suggesting that any of the three methods could be validly used for such studies with confidence. Escherichia coli and Klebsiella pneumoniae were the two major coliforms identified among 98 coliform isolates obtained from the various food samples, of which 78 (79.6%) were assumed to be of human origin on account of their ability to grow at 44 degrees C. The level of coliform contamination in the food samples from vendors and restaurants (geometric mean count 7.64-9.21; MPN > or = 50) were above the accepted 10(4) colony-forming unit/g or MPN < or = 10 limits. The results of the study, therefore, call for stringent supervision and implementation of food-safety practices and regular education on food and personal hygiene among food vendors. PMID:22283029

Sustained increase in resident meal time hand hygiene through an interdisciplinary intervention engaging long-term care facility residents and staff.  


Hand hygiene by patients may prevent acquisition and dissemination of health care-associated pathogens, but limited efforts have been made to engage patients in hand hygiene interventions. In a long-term care facility, we found that residents were aware of the importance of hand hygiene, but barriers, such as inaccessible products or difficult to use products, limited compliance. A dramatic and sustained improvement in meal time hand hygiene was achieved through engagement of staff and residents. PMID:25637117

Phenotypic characterization of Salmonella isolated from food production environments associated with low-water activity foods.  


Salmonella can survive for extended periods of time in low-moisture environments posing a challenge for modern food production. This dangerous pathogen must be controlled throughout the production chain with a minimal risk of dissemination. Limited information is currently available describing the behavior and characteristics of this important zoonotic foodborne bacterium in low-moisture food production environments and in food. In our study, the phenotypes related to low-moisture survival of 46 Salmonella isolates were examined. Most of the isolates in the collection could form biofilms under defined laboratory conditions, with 57% being positive for curli fimbriae production and 75% of the collection positive for cellulose production, which are both linked with stronger biofilm formation. Biocides in the factory environment to manage hygiene were found to be most effective against planktonic cells but less so when the same bacteria were surface dried or present as a biofilm. Cellulose-producing isolates were better survivors when exposed to a biocide compared with cellulose-negative isolates. Examination of Salmonella growth of these 18 serotypes in NaCl, KCl, and glycerol found that glycerol was the least inhibitory of these three humectants. We identified a significant correlation between the ability to survive in glycerol and the ability to survive in KCl and biofilm formation, which may be important for food safety and the protection of public health.

The hygienic efficacy of different hand-drying methods: a review of the evidence.  


The transmission of bacteria is more likely to occur from wet skin than from dry skin; therefore, the proper drying of hands after washing should be an integral part of the hand hygiene process in health care. This article systematically reviews the research on the hygienic efficacy of different hand-drying methods. A literature search was conducted in April 2011 using the electronic databases PubMed, Scopus, and Web of Science. Search terms used were hand dryer and hand drying. The search was limited to articles published in English from January 1970 through March 2011. Twelve studies were included in the review. Hand-drying effectiveness includes the speed of drying, degree of dryness, effective removal of bacteria, and prevention of cross-contamination. This review found little agreement regarding the relative effectiveness of electric air dryers. However, most studies suggest that paper towels can dry hands efficiently, remove bacteria effectively, and cause less contamination of the washroom environment. From a hygiene viewpoint, paper towels are superior to electric air dryers. Paper towels should be recommended in locations where hygiene is paramount, such as hospitals and clinics. PMID:22656243

Self-reported dental hygiene, obesity, and systemic inflammation in a pediatric rural community cohort  

PubMed Central

Background A growing body of epidemiologic evidence links oral health, obesity, and cardiovascular health, though few studies have reported on these relationships in children. While underlying mechanisms are unclear, adult studies have suggested sub-acute systemic inflammation, also implicated in the etiology of both obesity and cardiovascular disease. This study investigated associations between self-reported dental hygiene, obesity, and systemic inflammation in children. Methods 128 children < 19 years of age from rural counties in West Virginia participated in a community-based health screening that included anthropometric assessments, blood collection, and a questionnaire about dental hygiene and self-assessed oral health. Results Participants ranged from 3.0-18.7 years. Univariate analysis demonstrated an association between parent-reported dental hygiene, including frequency of preventive dental care and parent-assessed overall dental health, and markers of systemic inflammation but not obesity. In multivariable regression, parent-assessed overall dental health and obesity were independent predictors of systemic inflammation, after adjustment for age, gender, and parent education. Conclusions This is the first known study of the association between dental hygiene, obesity, and systemic inflammation in children. These results highlight the importance of preventive dental care in overall, systemic health in children and are consistent with previous reports in adults. PMID:20849640

Hand hygiene audits utilising medical student observers and measuring product consumption  

Microsoft Academic Search

Hand hygiene is critical in controlling hospital-acquired infection. Traditional methods of surveillance are resource-intensive. They are often influenced by the awareness of being observed (the Hawthorne effect) and so observers must be unobtrusive. In Singapore, medical students are not part of the ward team and are potentially excellent auditors. Utilising students may have additional benefits such as infection control training

Use of hygiene protocols to control the spread of viruses in a hotel.  


The goals of this study were to observe the spread of viruses in a hotel setting and to assess the effectiveness of a hygiene intervention in reducing their spread. Selected fomites in one hotel room were inoculated with bacteriophage ?x-174, and fomites in a conference center within the same hotel were inoculated using bacteriophage MS2. Cleaning of the contaminated room resulted in the spread of viruses to other rooms by the housekeeping staff. Furthermore, viruses were transferred by hotel guests to the conference center and a communal kitchen area. Additionally, conference attendees transferred viruses from the conference center to their hotel rooms and a communal kitchen area. This study demonstrated how viruses can be spread throughout a hotel setting by both housekeepers and guests. A hygiene intervention, which included providing hand hygiene products and facial tissues to the guests and disinfecting solutions with disposable wipes to the housekeeping staff, was successful in reducing the spread of viruses between the hotel guest rooms and conference center. The hygiene intervention resulted in significantly reduced transfer of the ?x-174 between the contaminated hotel room and other hotel rooms, communal areas, and the conference center (p = 0.02).

A Comparative Study on Menstrual Hygiene Among Urban and Rural Adolescent Girls of West Bengal  

PubMed Central

Background: Menstruation is a normal physiological process to the females but sometimes it is considered as unclean phenomenon in the society. Objectives: To compare the perceptions of different aspects of menstrual hygiene between adolescent girls of rural and urban area. Materials and Methods: A community-based cross-sectional study was conducted from April 2013 to September 2013 in urban and rural area of South 24, Paraganas, West Bengal among 541 adolescent school girls in the age group of 13–18 years. Data were collected by the predesigned and pretested questionnaires. Result: Only 37.52% girls were aware of menstruation prior to attainment of menarche. The difference in the awareness regarding menstruation in urban and rural area was highly significant. Only 36% girls in the urban and 54.88% girls in the rural area used homemade sanitary pads and reused the same in the subsequent period. Satisfactory Cleaning of external genitalia was practiced by only 47.63% of the urban and 37.96% of the rural girls. This study found differences in hygienic practices followed by adolescent girls in urban and rural area. Conclusion: Hygienic practices during menstruation were unsatisfactory in the rural area as compared to the urban area. Girls should be educated about the proper hygienic practices as well as bring them out of traditional beliefs, misconceptions, and restrictions regarding menstruation.

A profitable hygiene system: not an undervalued practice resource, part 2.  


In this 2-part article, we have addressed the correct methods to use in selecting the right hygienist and the importance of creating a purposeful vision for your dental hygiene department. We have touched on the role of having the doctor discuss practice expectations, and the qualities and traits a dental hygienist should possess. Finally we have briefly reviewed some ideas regarding hygienist compensation as well as the integration of the new technologies to help you build a successful, productive, and profitable dental hygiene department. Many of today's practice owners have invested hundreds of thousands of dollars in updated facilities and state-of-the-art technology. They have invested in management and leadership courses, developed their business acumen, and have worked to insure that their clinical assistants' skills stay sharp. However, when it comes to dental hygiene, too many practices still operate a 1980s-style "prophylaxis mindset palace." The time has come for more dentists to embrace up-to-date dental hygiene practice standards. PMID:19275088

Incidence of Staphylococcus aureus and Analysis of Associated Bacterial Communities on Food Industry Surfaces  

PubMed Central

Biofilms are a common cause of food contamination with undesirable bacteria, such as pathogenic bacteria. Staphylococcus aureus is one of the major bacteria causing food-borne diseases in humans. A study designed to determine the presence of S. aureus on food contact surfaces in dairy, meat, and seafood environments and to identify coexisting microbiota has therefore been carried out. A total of 442 samples were collected, and the presence of S. aureus was confirmed in 6.1% of samples. Sixty-three S. aureus isolates were recovered and typed by random amplification of polymorphic DNA (RAPD). Profiles were clustered into four groups which were related to specific food environments. All isolates harbored some potential virulence factors such as enterotoxin production genes, biofilm formation-associated genes, antibiotic resistance, or lysogeny. PCR-denaturing gradient gel electrophoresis (PCR-DGGE) fingerprints of bacterial communities coexisting with S. aureus revealed the presence of bacteria either involved in food spoilage or of concern for food safety in all food environments. Food industry surfaces could thus be a reservoir for S. aureus forming complex communities with undesirable bacteria in multispecies biofilms. Uneven microbiological conditions were found in each food sector, which indicates the need to improve hygienic conditions in food processing facilities, particularly the removal of bacterial biofilms, to enhance the safety of food products.

Oral Hygiene and Cardiometabolic Disease Risk in the Survey of the Health of Wisconsin  

PubMed Central

Objectives Poor oral health is an increasingly recognized risk factor for cardiovascular disease (CVD) and type 2 diabetes (T2D), but little is known about the association between toothbrushing or flossing and cardiometabolic disease risk. The purpose of this study was to examine the degree to which an oral hygiene index was associated with CVD and T2D risk scores among disease-free adults in the Survey of the Health of Wisconsin. Methods All variables were measured in 2008–2010 in this cross-sectional design. Based on toothbrushing and flossing frequency, and oral hygiene index (poor, fair, good, excellent) was created as the primary predictor variable. The outcomes, CVD and T2D risk score, were based on previous estimates from large cohort studies. There were 712 and 296 individuals with complete data available for linear regression analyses in the CVD and T2D samples, respectively. Results After covariate adjustment, the final model indicated that participants in the excellent (?±SE=?0.019±0.008, p=0.020) oral hygiene category had a significantly lower CVD risk score as compared to participants in the poor oral hygiene category. Sensitivity analyses indicated that both toothbrushing and flossing were independently associated with CVD risk score, and various modifiable risk factors. Oral hygiene was not significantly associated with T2D risk score. Conclusions Regular toothbrushing and flossing are associated with a more favorable CVD risk profile, but more experimental research is needed in this area to precisely determine the effects of various oral self-care maintenance behaviors on the control of individual cardiometabolic risk factors. These findings may inform future joint medical-dental initiatives designed to close gaps in the primary prevention of oral and systemic diseases. PMID:23106415

Can a school-based hand hygiene program reduce asthma exacerbations among elementary school children?  

PubMed Central

Background Viral upper respiratory infections have been implicated as a major cause of asthma exacerbations among school age children. Regular hand washing is the most effective method to prevent the spread of viral respiratory infections but, effective hand washing practices are difficult to establish in schools. Objectives This randomized controlled trial evaluated whether a standardized regimen of hand washing plus alcohol-based hand sanitizer could reduce asthma exacerbations more than schools’ usual hand hygiene practices. Methods This was a two year, community-based, randomized controlled crossover trial. Schools were randomized to usual care then intervention (Sequence 1) or intervention then usual care (Sequence 2). Intervention schools were provided with alcohol-based hand sanitizer, hand soap, and hand hygiene education. The primary outcome was the proportion of students experiencing an asthma exacerbation each month. Generalized estimating equations were used to model the difference in the marginal rate of exacerbations between sequences while controlling for individual demographic factors and the correlation within each student and between students within each school. Results 527 students with asthma were enrolled among 31 schools. The hand hygiene intervention did not reduce the number of asthma exacerbations as compared to the schools’ usual hand hygiene practices (p=0.132). There was a strong temporal trend as both sequences experienced fewer exacerbations during Year 2 as compared to Year 1 (p<0.001). Conclusions While the intervention was not found to be effective, the results were confounded by the H1N1 influenza pandemic that resulted in substantially increased hand hygiene behaviors and resources in usual care schools. Therefore, these results should be viewed cautiously. PMID:23069487

Hygienic support of the ISS air quality (main achievements and prospects)  

NASA Astrophysics Data System (ADS)

Hygienic preventive measures during pre-flight processing of manned spaceships, selection of polymeric materials, sanitary-hygienic evaluation of cargo and scientific hardware to be used on the ISS and life support systems allow to maintain air quality in limits of regulatory requirements. However, graduate increase of total air contamination by harmful chemicals is observed as service life of the ISS gets longer. It is caused by polymeric materials used on the station overall quantity rise, by additional contamination brought by cargo spacecrafts and modules docking to the ISS and by the cargo. At the same time the range of contaminants that are typical for off-gassing from polymeric materials where modern stabilizers, plasticizers, flame retarders and other additives are used gets wider. In resolving the matters of the ISS service life extension the main question of hygienic researches is to determine real safe operation life of the polymeric material used in structures and hardware of the station, including: begin{itemize} research of polymers degradation (ageing) and its effect on intensity of off gassing and its toxicity; begin{itemize} introduction of polymers with minimal volatile organic compounds off gassing under conditions of space flight and thermal-oxidative degradation. In order to ensure human safety during long-term flight it is important to develop: begin{itemize} real-time air quality monitoring systems, including on-line analysis of highly toxic contaminants evolving during thermo-oxidative degradation of polymer materials and during blowouts of toxic contaminants; begin{itemize} hygienic standards of contaminants level for extended duration of flight up to 3 years. It is essential to develop an automated control system for on-line monitoring of toxicological status and to develop hygienic and engineer measures of its management in order to ensure crew members safety during off-nominal situation.

[Food allergy, food intolerance or functional disorder?].  


The term "food allergy" is widely misused for all sorts of symptoms and diseases caused by food. Food allergy (FA) is an adverse reaction to food (food hypersensitivity) occurring in susceptible individuals, which is mediated by a classical immune mechanism specific for the food itself. The best established mechanism in FA is due to the presence of IgE antibodies against the offending food. Food intolerance (FI) are all non-immune-mediated adverse reactions to food. The subgroups of FI are enzymatic (e.g. lactose intolerance due to lactase deficiency), pharmacological (reactions against biogenic amines, histamine intolerance), and undefined food intolerance (e.g. against some food additives). The diagnosis of an IgE-mediated FA is made by a carefully taken case history, supported by the demonstration of an IgE sensitization either by skin prick tests or by in vitro tests, and confirmed by positive oral provocation. For scientific purposes the only accepted test for the confirmation of FA/FI is a properly performed double-blind, placebo-controlled food challenge (DBPCFC). A panel of recombinant allergens, produced as single allergenic molecules, may in future improve the diagnosis of IgE-mediated FA. Due to a lack of causal treatment possibilities, the elimination of the culprit "food allergen" from the diet is the only therapeutic option for patients with real food allergy. PMID:19340768

Chronobiology, endocrinology, and energy- and food-reward homeostasis.  


Energy- and food-reward homeostasis is the essential component for maintaining energy balance and its disruption may lead to metabolic disorders, including obesity and diabetes. Circadian alignment, quality sleep and sleep architecture in relation to energy- and food-reward homeostasis are crucial. A reduced sleep duration, quality sleep and rapid-eye movement sleep affect substrate oxidation, leptin and ghrelin concentrations, sleeping metabolic rate, appetite, food reward, hypothalamic-pituitary-adrenal (HPA)-axis activity, and gut-peptide concentrations, enhancing a positive energy balance. Circadian misalignment affects sleep architecture and the glucose-insulin metabolism, substrate oxidation, homeostasis model assessment of insulin resistance (HOMA-IR) index, leptin concentrations and HPA-axis activity. Mood disorders such as depression occur; reduced dopaminergic neuronal signaling shows decreased food reward. A good sleep hygiene, together with circadian alignment of food intake, a regular meal frequency, and attention for protein intake or diets, contributes in curing sleep abnormalities and overweight/obesity features by preventing overeating; normalizing substrate oxidation, stress, insulin and glucose metabolism including HOMA-IR index, and leptin, GLP-1 concentrations, lipid metabolism, appetite, energy expenditure and substrate oxidation; and normalizing food reward. Synchrony between circadian and metabolic processes including meal patterns plays an important role in the regulation of energy balance and body-weight control. Additive effects of circadian alignment including meal patterns, sleep restoration, and protein diets in the treatment of overweight and obesity are suggested. PMID:23387351

The role and utilisation of public health evaluations in Europe: a case study of national hand hygiene campaigns  

PubMed Central

Background Evaluations are essential to judge the success of public health programmes. In Europe, the proportion of public health programmes that undergo evaluation remains unclear. The European Centre for Disease Prevention and Control sought to determine the frequency of evaluations amongst European national public health programmes by using national hand hygiene campaigns as an example of intervention. Methods A cohort of all national hand hygiene campaigns initiated between 2000 and 2012 was utilised for the analysis. The aim was to collect information about evaluations of hand hygiene campaigns and their frequency. The survey was sent to nominated contact points for healthcare-associated infection surveillance in European Union and European Economic Area Member States. Results Thirty-six hand hygiene campaigns in 20 countries were performed between 2000 and 2012. Of these, 50% had undergone an evaluation and 55% of those utilised the WHO hand hygiene intervention self-assessment tool. Evaluations utilised a variety of methodologies and indicators in assessing changes in hand hygiene behaviours pre and post intervention. Of the 50% of campaigns that were not evaluated, two thirds reported that both human and financial resource constraints posed significant barriers for the evaluation. Conclusion The study identified an upward trend in the number of hand hygiene campaigns implemented in Europe. It is likely that the availability of the internationally-accepted evaluation methodology developed by the WHO contributed to the evaluation of more hand hygiene campaigns in Europe. Despite this rise, hand hygiene campaigns appear to be under-evaluated. The development of simple, programme-specific, standardised guidelines, evaluation indicators and other evidence-based public health materials could help promote evaluations across all areas of public health.

Occurrence and hygienic relevance of fungi in drinking water.  


Fungi, above all filamentous fungi, can occur almost everywhere, even in water. They can grow in such a quantity in water that they can affect the health of the population or have negative effects on food production. There are several reports of fungal growth in water from different countries, but to our knowledge none from Austria so far. The aim of this study was to gain an overview of the spectrum of filamentous fungi and yeasts in drinking water systems. Thirty-eight water samples from drinking water and groundwater were analysed. Fungi were isolated by using membrane filtration and plating method with subsequent cultivation on agar plates. The different taxa of fungi were identified using routine techniques as well as molecular methods. Fungi were isolated in all water samples examined. The mean value for drinking water was 9.1 CFU per 100 ml and for groundwater 5400 CFU per 100 ml. Altogether 32 different taxa of fungi were found. The taxa which occurred most frequently were Cladosporium spp., Basidiomycetes and Penicillium spp. (74.6%, 56.4% and 48.7%, respectively). This study shows that drinking water can be a reservoir for fungi, among them opportunists, which can cause infections in immunosuppressed patients. PMID:18254755

Food insecurity, neighborhood food access, and food assistance in Philadelphia.  


An estimated 17.6 million American households were food insecure in 2012, meaning they were unable to obtain enough food for an active and healthy life. Programs to augment local access to healthy foods are increasingly widespread, with unclear effects on food security. At the same time, the US government has recently enacted major cuts to federal food assistance programs. In this study, we examined the association between food insecurity (skipping or reducing meal size because of budget), neighborhood food access (self-reported access to fruits and vegetables and quality of grocery stores), and receipt of food assistance using the 2008, 2010, and 2012 waves of the Southeastern Pennsylvania Household Health Survey. Of 11,599 respondents, 16.7% reported food insecurity; 79.4% of the food insecure found it easy or very easy to find fruits and vegetables, and 60.6% reported excellent or good quality neighborhood grocery stores. In our regression models adjusting for individual- and neighborhood-level covariates, compared to those who reported very difficult access to fruits and vegetables, those who reported difficult, easy or very easy access were less likely to report food insecurity (OR 0.62: 95% CI 0.43-0.90, 0.33: 95% CI 0.23-0.47, and 0.28: 95% CI 0.20-0.40). Compared to those who reported poor stores, those who reported fair, good, and excellent quality stores were also less likely to report food insecurity (OR 0.81: 95% CI 0.60-1.08, 0.58: 95% CI 0.43-0.78, and 0.43: 95% CI 0.31-0.59). Compared to individuals not receiving food assistance, those receiving Supplemental Nutrition Assistance Program (SNAP) benefits were significantly more likely to be food insecure (OR 1.36: 95% CI 1.11-1.67), while those receiving benefits from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) (OR 1.17: 95% CI 0.77-1.78) and those receiving both SNAP and WIC (OR 0.84: 95% CI 0.61-1.17) did not have significantly different odds of food insecurity. In conclusion, better neighborhood food access is associated with lower risk of food insecurity. However, most food insecure individuals reported good access. Improving diet in communities with high rates of food insecurity likely requires not only improved access but also greater affordability. PMID:25047157

Short-term impact of oral hygiene training package to Anganwadi workers on improving oral hygiene of preschool children in North Indian City  

PubMed Central

Background Globally, dental caries is categorized in the list of public health problems in preschool children. In India, lack of availability and affordability of oral health enhances the cost of treatment and care. Empowering community workers like anganwadi workers (AWWs) in oral health, and providing basic oral health awareness to the mothers through them can be feasible model. So, the present study was conducted to evaluate the short-term impact of Oral Hygiene Training Package (OHTP) to AWWs on improving oral hygiene of preschool children. Methods This before and after comparison field trial was done in Anganwadi centres (AWCs) of Chandigarh city, India. 534 children aged 36-72 months attending 21 AWCs were examined before and after imparting trainings to AWWs. OHTP was administered to AWWs, which consisted of power-point presentation and demonstrated the skills like proper brushing technique, plaque disclosure, flossing technique, gum massaging etc. The AWWs later imparted training to mothers in their respective AWCs. Post intervention data was collected after three months. Outcome measures were improvement in oral health status (plaque, debris, gingival health), oral habits (brushing, rinsing) and decrease in caries activity (Snyder test). Results Prevalence of dental caries was found to be 48.3%. Only 4.1% of the population reported brushing twice which increased significantly to 9.9% post-intervention (p = 0.000). There was a significant decrease in debris (78.3% to 54.1%), and stage-1 plaque (75.5 to 66.5%) in the oral cavity. Caries activity by Snyder’s test decreased from 48.2% to 31.2% (p = 0.01) post-intervention. Conclusions Controlled trials of using AWWs to improve oral hygiene appear to be justified.

Low-water activity foods: increased concern as vehicles of foodborne pathogens.  


Foods and food ingredients with low water activity (a(w)) have been implicated with increased frequency in recent years as vehicles for pathogens that have caused outbreaks of illnesses. Some of these foodborne pathogens can survive for several months, even years, in low-a(w) foods and in dry food processing and preparation environments. Foodborne pathogens in low-a(w) foods often exhibit an increased tolerance to heat and other treatments that are lethal to cells in high-a(w) environments. It is virtually impossible to eliminate these pathogens in many dry foods or dry food ingredients without impairing organoleptic quality. Control measures should therefore focus on preventing contamination, which is often a much greater challenge than designing efficient control measures for high-a(w) foods. The most efficient approaches to prevent contamination are based on hygienic design, zoning, and implementation of efficient cleaning and sanitation procedures in the food processing environment. Methodologies to improve the sensitivity and speed of assays to resuscitate desiccated cells of foodborne pathogens and to detect them when present in dry foods in very low numbers should be developed. The goal should be to advance our knowledge of the behavior of foodborne pathogens in low-a(w) foods and food ingredients, with the ultimate aim of developing and implementing interventions that will reduce foodborne illness associated with this food category. Presented here are some observations on survival and persistence of foodborne pathogens in low-a(w) foods, selected outbreaks of illnesses associated with consumption of these foods, and approaches to minimize safety risks.

Challenges in Developing Competency-based Training Curriculum for Food Safety Regulators in India  

PubMed Central

Context: The Food Safety and Standards Act have redefined the roles and responsibilities of food regulatory workforce and calls for highly skilled human resources as it involves complex management procedures. Aims: 1) Identify the competencies needed among the food regulatory workforce in India. 2) Develop a competency-based training curriculum for food safety regulators in the country. 3) Develop training materials for use to train the food regulatory workforce. Settings and Design: The Indian Institute of Public Health, Hyderabad, led the development of training curriculum on food safety with technical assistance from the Royal Society for Public Health, UK and the National Institute of Nutrition, India. The exercise was to facilitate the implementation of new Act by undertaking capacity building through a comprehensive training program. Materials and Methods: A competency-based training needs assessment was conducted before undertaking the development of the training materials. Results: The training program for Food Safety Officers was designed to comprise of five modules to include: Food science and technology, Food safety management systems, Food safety legislation, Enforcement of food safety regulations, and Administrative functions. Each module has a facilitator guide for the tutor and a handbook for the participant. Essentials of Food Hygiene-I (Basic level), II and III (Retail/ Catering/ Manufacturing) were primarily designed for training of food handlers and are part of essential reading for food safety regulators. Conclusion: The Food Safety and Standards Act calls for highly skilled human resources as it involves complex management procedures. Despite having developed a comprehensive competency-based training curriculum by joint efforts by the local, national, and international agencies, implementation remains a challenge in resource-limited setting.

Mood Food  

PubMed Central

Background Much lore but few studies describe a relation of chocolate to mood. We examined the cross-sectional relationship of chocolate consumption with depressed mood in adult men and women. Methods A sample of 1018 adults (694 men and 324 women) from San Diego, California, without diabetes or known coronary artery disease was studied in a cross-sectional analysis. The 931 subjects who were not using antidepressant medications and provided chocolate consumption information were the focus of the analysis. Mood was assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Cut points signaling a positive depression screen result (CES-D score, ?16) and probable major depression (CES-D score, ?22) were used. Chocolate servings per week were provided by 1009 subjects. Chocolate consumption frequency and rate data from the Fred Hutchinson Food Frequency Questionnaire were also available for 839 subjects. Chocolate consumption was compared for those with lower vs higher CES-D scores. In addition, a test of trend was performed. Results Those screening positive for possible depression (CES-D score ?16) had higher chocolate consumption (8.4 servings per month) than those not screening positive (5.4 servings per month) (P = .004); those with still higher CES-D scores (?22) had still higher chocolate consumption (11.8 servings per month) (P value for trend, <.01). These associations extended to both men and women. These findings did not appear to be explained by a general increase in fat, carbohydrate, or energy intake. Conclusion Higher CES-D depression scores were associated with greater chocolate consumption. Whether there is a causal connection, and if so in which direction, is a matter for future prospective study. PMID:20421555

Food safety in hospital: knowledge, attitudes and practices of nursing staff of two hospitals in Sicily, Italy  

PubMed Central

Background Food hygiene in hospital poses peculiar problems, particularly given the presence of patients who could be more vulnerable than healthy subjects to microbiological and nutritional risks. Moreover, in nosocomial outbreaks of infectious intestinal disease, the mortality risk has been proved to be significantly higher than the community outbreaks and highest for foodborne outbreaks. On the other hand, the common involvement in the role of food handlers of nurses or domestic staff, not specifically trained about food hygiene and HACCP, may represent a further cause of concern. The purpose of this study was to evaluate knowledge, attitudes, and practices concerning food safety of the nursing staff of two hospitals in Palermo, Italy. Association with some demographic and work-related determinants was also investigated. Methods The survey was conducted, by using a semi-structured questionnaire, in March-November 2005 in an acute general hospital and a paediatric hospital, where nursing staff is routinely involved in food service functions. Results Overall, 401 nurses (279, 37.1%, of the General Hospital and 122, 53.5%, of the Paediatric Hospital, respectively) answered. Among the respondents there was a generalized lack of knowledge about etiologic agents and food vehicles associated to foodborne diseases and proper temperatures of storage of hot and cold ready to eat foods. A general positive attitude towards temperature control and using clothing and gloves, when handling food, was shared by the respondents nurses, but questions about cross-contamination, refreezing and handling unwrapped food with cuts or abrasions on hands were frequently answered incorrectly. The practice section performed better, though sharing of utensils for raw and uncooked foods and thawing of frozen foods at room temperatures proved to be widely frequent among the respondents. Age, gender, educational level and length of service were inconsistently associated with the answer pattern. More than 80% of the respondent nurses did not attend any educational course on food hygiene. Those who attended at least one training course fared significantly better about some knowledge issues, but no difference was detected in both the attitude and practice sections. Conclusion Results strongly emphasize the need for a safer management of catering in the hospitals, where non professional food handlers, like nursing or domestic staff, are involved in food service functions.

Multicentre study on hand hygiene facilities and practice in the Mediterranean area: results from the NosoMed Network.  


Hand hygiene literature is scarce in the southern Mediterranean area. In order to establish a baseline position, a study was performed in four Mediterranean countries. Seventy-seven hospital wards in 22 hospitals were enrolled and information on hand hygiene practice and facilities were collected. The overall compliance rate was very low (27.6%), and was significantly higher where the perceived risk was considered to be high. Intensive care units showed the highest level of compliance. Analysis by country indicated higher compliance in Egypt (52.8%) and Tunisia (32.3%) compared with Algeria (18.6%) and Morocco (16.9%). Facilities for hand hygiene, particularly consumables, were shown to be deficient. Multi-approach programmes combining the production of official local recommendations, education and regular evaluation of hand hygiene practice are much needed to improve the present situation.

A review of video exposure monitoring as an occupational hygiene tool.  


This study reviews use of video exposure monitoring (VEM, also known as PIMEX) as an occupational hygiene tool since its inception in the mid-1980s. VEM involves the combination of real-time monitoring instruments, usually for gases/vapours and dust, with video of the worker's activities. VEM is an established method used by practitioners in different countries. The technical aspects of these VEM systems are described, then applications of VEM are discussed, focussing on task analysis, training (risk communication), encouraging worker participation in and motivation for improvements in the workplace environment and occupational hygiene research. The experiences from these applications are used to illustrate how exposure visualization with video can act as a catalyst, initiating a change process in the workplace. Finally, the role of VEM as a workplace improvement tool, now and in the future, is discussed. PMID:15701684

Comparative Effects of Gamma Irradiation and Ozone Treatment on Hygienic Quality of Korean Red Ginseng Powder  

NASA Astrophysics Data System (ADS)

For the purpose of improving hygienic quality of Korean red ginseng powder, the comparative effects of gamma irradiation and ozone treatment on the microbial and physicochemical properties were investigated. Gamma irradiation at 7.5 kGy resulted in sterilization of total aerobic bacteria, molds and coliforms below detective levels, while ozone treatment for 8 hours up to 18 ppm did not sufficiently eliminate the microorganisms of the red ginseng powder. Physicochemical properties including compositions of the red ginseng saponin (ginsenosides) and fatty acids, pH and hydrogen doanting activity were not significantly changed by gamma irradiation, whereas, ozone treatment caused significant changes in fatty acid compositions, TBA value, pH, acidity and hydrogen donating activity. The results from this study led us to conclude that gamma irradiation was more effective than ozone treatment both for the improvement of hygienic quality and for the maintenance of physicochemical quality of red ginseng powder.

Hygienic-toxicological aspects of exposure to lead. A critical review.  


This review on hygienic, toxicologic and ecologic aspects of environmental burden of lead deals with the following topics: occurrence, production and use of lead; metabolism of lead and experimental toxicology of lead; toxicity of lead to man; hygienic and ecologic aspects of lead pollution. Lead ore mining and processing, production of lead-acid batteries and combustion of gasoline containing tetraethyl-lead as an anti-knock ingredient constitute at present the most important sources of lead pollution. The last named source of lead pollution in urban atmosphere is most hazardous to human health. Attempts to reduce this health hazard include use of additive-free gasoline, or replacement of tetraethyl lead by other anti-knock agents, e. g. by tetraethylcopper. The experiments with the use of organic compounds of manganese have failed to succeed. The possibility of biological monitoring of occupational and nonoccupational exposures to lead is discussed in detail in this review. PMID:6761391

[Hygienic evaluation of technological, design and sanitary-technical solutions for large-scale chemical plants].  


Complexes of technologic solution for the construction of large-scale plants producing ammonia, nitric and sulfuric acids, ammonium nitrate, carbomide and caprolactam , are characterized by both positive and negative hygienic features. The hygienic shortcomings reveal themselves in sporadic increases of hazardous ingredients in concentrations up to the MAC and higher levels, as well as in unfavorable labour conditions when dealing with catalysts, storage operations, inter-enterprise transportation, dispatching of raw materials and finished products, in the contamination of the in-going ventilation air, and in the compound influence of low temperatures and toxic substances. The concentration of several large-capacity enterprises in the same area entails large-scale discharges in the atmosphere with subsequent contamination of the surrounding protection areas. The author proposes a set of major preventive measures. PMID:2150391

Seven suggestive quantitative trait loci influence hygienic behavior of honey bees  

NASA Astrophysics Data System (ADS)

In 1964, Walter Rothenbuhler proposed a two-gene model to explain phenotypic variance in the remarkable behavior in which honey bee workers remove dead brood from their colonies. Rothenbuhler's model proposed that one locus controls the uncapping of brood cells containing dead pupae, while a second controls the removal of the cell contents. We show here, through molecular techniques and quantitative trait loci (QTL) linkage mapping, that the genetic basis of hygienic behavior is more complex, and that many genes are likely to contribute to the behavior. In our cross, we detected seven suggestive QTLs associated with hygienic behavior. Each detected QTL controlled only 9-15% of the observed phenotypic variance in the character.

Examination of social networking professionalism among dental and dental hygiene students.  


Becoming a dental professional requires one to apply ethical decision making skills and demonstrate high standards of professionalism in practice, including the way professionals present themselves to the public. With social media as an evergrowing part of personal and professional communications, this study aimed to determine the accessibility, amount, and type of unprofessional content on Facebook profiles of dental hygiene and dental students in a college of dentistry. The authors evaluated the online profiles of all 499 dental and dental hygiene students at The Ohio State University using objective measures that included existence of a profile, current privacy settings, and access to personally identifiable information. A sample of profiles were evaluated for unprofessional content including photos, comments, and wall posts. The majority of these students were found to use Facebook, with 61 percent having Facebook profiles. Dental hygiene students were more likely to have a Facebook profile than were dental students: 72.6 percent and 59.1 percent, respectively (p=0.027). The majority of the students' profiles had some form of privacy setting enabled, with only 4 percent being entirely open to the public. Fewer than 2 percent of the students allowed non-friends access to personal information. Based on in-depth analysis of the profiles, fourteen (5.8 percent) instances of unprofessionalism were recorded; the most common unprofessional content involved substance abuse. This study found that these dental and dental hygiene students frequently possessed an identifiable Facebook account and nearly half had some kind of personal information on their profile that could potentially be shared with the public. In some instances, the students gave patients, faculty, and potential employers access to content that is not reflective of a dental professional. Academic institutions should consider implementing policies that bring awareness to and address the use of social media in a professional environment. PMID:24192407

Hygiene and Other Early Childhood Influences on the Subsequent Function of the Immune System  

Microsoft Academic Search

The current ‘Darwinian’ synthesis of the hygiene (or ‘Old Friends’) hypothesis suggests that the increase in chronic inflammatory disorders that started in Europe in the mid-19th century and progressed until the late 20th century is at least partly attributable to immunodysregulation resulting from lack of exposure to microorganisms that were tasked by co-evolutionary processes with establishing the ‘normal’ background levels

Hand Hygiene – Evaluation of Three Disinfectant Hand Sanitizers in a Community Setting  

PubMed Central

Hand hygiene is acknowledged as the single most important measure to prevent nosocomial infections in the healthcare setting. Similarly, in non-clinical settings, hand hygiene is recognised as a key element in helping prevent the spread of infectious diseases. The aim of this study was to evaluate the efficacy of three different disinfectant hand sanitizers in reducing the burden of bacterial hand contamination in 60 healthy volunteers in a community setting, both before and after education about the correct use of hand sanitizers. The study is the first to evaluate the efficacy and ease of use of different formulations of hand rubs used by the general population. The products tested were: Sterillium (perfumed, liquid), desderman pure gel (odorless, gel) and Lavit (perfumed, spray). Sterillium and desderman are EN1500 (hygienic hand rub) certified products (available in pharmacy) and Lavit is non EN1500 certified and available in supermarkets. The two EN1500 certified products were found to be significantly superior in terms of reducing bacterial load. desderman pure gel, Sterillium and Lavit reduced the bacterial count to 6.4%, 8.2% and 28.0% respectively. After education in the correct use of each hand rub, the bacterial load was reduced even further, demonstrating the value of education in improving hand hygiene. Information about the testers' perceptions of the three sanitizers, together with their expectations of a hand sanitizer was obtained through a questionnaire. Efficacy, followed by skin compatibility were found to be the two most important attributes of a hand disinfectant in our target group. PMID:25379773

No Genetic Tradeoffs between Hygienic Behaviour and Individual Innate Immunity in the Honey Bee, Apis mellifera  

PubMed Central

Many animals have individual and social mechanisms for combating pathogens. Animals may exhibit short-term physiological tradeoffs between social and individual immunity because the latter is often energetically costly. Genetic tradeoffs between these two traits can also occur if mutations that enhance social immunity diminish individual immunity, or vice versa. Physiological tradeoffs between individual and social immunity have been previously documented in insects, but there has been no study of genetic tradeoffs involving these traits. There is strong evidence that some genes influence both innate immunity and behaviour in social insects – a prerequisite for genetic tradeoffs. Quantifying genetic tradeoffs is critical for understanding the evolution of immunity in social insects and for devising effective strategies for breeding disease-resistant pollinator populations. We conducted two experiments to test the hypothesis of a genetic tradeoff between social and individual immunity in the honey bee, Apis mellifera. First, we estimated the relative contribution of genetics to individual variation in innate immunity of honey bee workers, as only heritable traits can experience genetic tradeoffs. Second, we examined if worker bees with hygienic sisters have reduced individual innate immune response. We genotyped several hundred workers from two colonies and found that patriline genotype does not significantly influence the antimicrobial activity of a worker’s hemolymph. Further, we did not find a negative correlation between hygienic behaviour and the average antimicrobial activity of a worker’s hemolymph across 30 honey bee colonies. Taken together, our work indicates no genetic tradeoffs between hygienic behaviour and innate immunity in honey bees. Our work suggests that using artificial selection to increase hygienic behaviour of honey bee colonies is not expected to concurrently compromise individual innate immunity of worker bees.

A public aid clinic prototype: utilizing a dental hygiene educational facility to increase access to care.  


Few dentists in a rural Midwestern community participate in providing oral health care to public aid recipients. In response, faculty at a baccalaureate degree dental hygiene program located at Southern illinois University, Carbondale (SIUC) proposed, developed, and implemented the Heartland Dental Clinic to serve Medicaid participants. The unique program utilizes existing facilities, staff, and students to provide comprehensive oral health care to underserved populations. The state awarded a small grant to cover start-up costs. Two dental units were upgraded with fiber optics to allow restorative procedures. Dental hygiene students provide intake examinations and preventive care, while a staff dentist provides restorative care, dentures, and examinations. Dental technology students and faculty fabricate prostheses. A part-time clinic manager facilitates communication, patient scheduling, and billing. Two local Rotary Club members volunteer as receptionists for the clinic on the one evening per week that the clinic operates. The Rotary Club purchased educational pamphlets, a television/VCR, videotapes, and two signs for the clinic. By locating the clinic in the existing SIUC facility and utilizing dental hygiene students, a staff dentist, volunteer receptionists and dentists, student workers, and health care management interns, the clinic overhead costs have been kept to a minimum. The clinic provides a unique opportunity for dental hygiene students to experience firsthand scheduling, billing, and treating public aid patients while providing patients with an additional source for oral health care. The Heartland Dental Clinic model represents a cost effective method for increasing oral health access to underserved populations while also benefiting students in an educational program.

Monitoring Hand Hygiene via Human Observers: How Should We be Sampling?  

PubMed Central

Objective To explore how hand-hygiene-observer scheduling influences the number of events and unique individuals observed. Design We deployed a mobile sensor network to capture detailed movement data for 6 categories of healthcare workers (HCWs) over 2 weeks Setting: The University of Iowa Hospital and Clinic’s MICU. Methods We recorded 33721 time-stamped HCW entries to and exits from patient rooms and considered each entry or exit an opportunity for hand hygiene. Architectural drawings were used to derive 4 optimal line-of-sight placements for observers. We ran simulations for different observer movement schedules, all with a budget of 1 hour total observation time. We considered observation times of 1–15, 15–30, 30 and 60 minutes per station. We stochastically generated HCW hand-hygiene compliance based on all data and recorded the total unit compliance as it would be reported by each simulated observer. Results Considering a 60 minute total observation period, aggregate simulated observers captured at best 1.7% of the average total number of opportunities per day and at worst 0.5%. The 1–15 minute schedule captures on average 16% fewer events than the 60-minute (i.e., static) schedule, but samples 17% more unique individuals. The 1–15 minute schedule also provides the best estimator of compliance for the duration of the shift, with a mean standard deviation of 17% versus 23% for the 60-minute schedule. Conclusions Our results show that observations are sensitive to different observers’ schedules and suggest the importance of using data-driven approaches to schedule hand-hygiene audits.

Effectiveness of Motivational Interviewing in Promoting Hand Hygiene of Nursing Personnel  

PubMed Central

Background: Motivational interviewing (M.I.) is an option for modifying an individual's behavior. It is used as an educational method in recent years. The aim of our study was to indicate whether or not education, using lecture alone and lecture with M.I., would affect the performance of nursing personnel regarding their hand hygiene. If so, which of these two methods were most effective for this purpose? Methods: This was an interventional study conducted in Bahrami Pediatric Hospital in Tehran. The study population consisted of all nursing personnel in the hospital. Considering the responsibilities of different nurses and their educational status, we divided them into three classes. The participants of each class were randomly assigned to either the control or experiment groups training lecture alone or lecture with M.I., respectively. We used Independent-t, Paired-t, Mann-Whitney U and Wilcoxon signed ranks tests for analysis. Results: Education using lecture alone improved the hand hygiene performance of nursing personnel only in the first and third classes (P = 0.002 and P = 0.001, respectively). Similarly, lecture combined with M.I. improved the hand hygiene performance of personnel in the first and third classes (P < 0.001 and P = 0.004, respectively). The latter method was more effective compared to lecture alone in the first and third classes (P < 0.001 and P = 0.013, respectively). Conclusions: Education based on lecturing improves hand hygiene performance among nursing personnel. It will be more effective if combined with M.I. PMID:23671777

Dental and dental hygiene students' perceptions of a standardized patient instructor conflict resolution program.  


The aim of this study was to examine students' perceptions of the value of a standardized patient instructor conflict resolution program designed to strengthen their communication and confidence during difficult patient conversations. Three cohorts of students at one dental school were part of the study: the dental class of 2013, the dental class of 2014, and the dental hygiene class of 2013. The same groups of students completed surveys immediately following the program and one, two, or three years afterwards. Response rates for the survey immediately after the program were 98 percent (n=99) of the dental class of 2013, 97 percent (n=103) of the dental class of 2014, and 100 percent (n=25) of the dental hygiene class of 2013. Response rates for the subsequent survey were 41.5 percent (n=42) of the dental class of 2013, 74.5 percent (n=79) of the dental class of 2014, and 100 percent (n=25) of the dental hygiene class of 2013. In the results, all students reported a high level of satisfaction in their immediate assessment of the program and its ability to prepare them for conflict situations. They also reported a high level of satisfaction in their retrospective self-assessment of conflict resolution skills. However, their assessment of the program's value and applicability appeared to have diminished over time. This study suggests that the program should continue being a part of both dental and dental hygiene curricula, with more training and guided experiences in self-assessment and perhaps supplemental experiences added.

The implications of Herzberg's "motivation-hygiene" theory for management in the Irish health sector.  


Given that they create what it sells, employees are the Irish Health service's most valuable asset. They are increasingly being asked to embrace change on many different levels. In order to facilitate this process, it behooves management to actively promote employee motivation. Herzberg et al's "motivation-hygiene" theory of motivation proposes that certain "motivator" and "hygiene" factors can respectively affect job satisfaction and dissatisfaction. Considering "motivators," better on-the-job performance may increase motivation. However, work overload can become a dissatisfier. Devolving equal levels of authority and responsibility and providing appropriate recognition may also serve to motivate. Likewise, providing opportunities for promotion and personal growth may maintain motivation, as might re-engineering of jobs so that work remains meaningful. Over time both salary and incentives may come to be viewed as entitlements and lose their ability to motivate. Other "hygiene" factors such as organizational policy and administrative structure, relations with others, job insecurity, physical working conditions, and quality of supervision can lead to job dissatisfaction. Hence, the theory of Herzberg et al usefully highlights many factors that may serve to motivate or demotivate employees. However, this theory does not reflect some of the realities of the modern health care work environment. PMID:16501377

Associations between sleep hygiene and insomnia severity in college students: cross-sectional and prospective analyses.  


Although a small number of studies characterized cross-sectional associations between sleep hygiene and insomnia severity, no prior study has examined their relationships prospectively. Further, the relationship between sleep hygiene and insomnia severity among college students has rarely been examined. This study examined the prevalence of diverse sleep hygiene behaviors and their associations with insomnia severity in two independent samples of college students from a cross-sectional (N=548; mean age=19; 59% female; 71% White) and a two-wave short-term prospective (N=157; mean age=19; 71% female; 76% White) study. A total of 12% to 13% of students reported clinically significant insomnia. On average, students reported frequent engagement in inconsistent sleep-wake schedules and lounging and worrying/thinking about important matters in the bed. Improper sleep scheduling, behaviors that promote arousal near bedtime, and uncomfortable sleeping environments were positively associated with cross-sectional insomnia severity. After controlling for other well-established risk factors, only improper sleep scheduling remained significant. Prospectively, baseline improper sleep scheduling predicted insomnia severity at a 2-month follow-up after controlling for baseline insomnia severity and other well-established risk factors. Together, findings suggest a potential unique role of improper sleep scheduling in insomnia among college students. PMID:25311289

Oral hygiene is an important factor for prevention of ventilator-associated pneumonia.  


Inadequate oral hygiene in intensive care units (ICUs) has been recognized as a critical issue, for it is an important risk factor for ventilator associated pneumonia (VAP). VAP is an aspiration pneumonia that occurs in mechanically ventilated patients, mostly caused by bacteria colonizing the oral cavity and dental plaque. It is the second most common nosocomial infection and the leading cause of complications and death in mechanically ventilated patients. It has been suggested that improvement of oral hygiene in ICU patients could lead to a reduced incidence of VAP. Although diverse oral care measures for ICU patients have been proposed in the literature, there is no evidence that could identify the most efficient ones. Although there are several evidence-based protocols, oral care measures are still performed inconsistently and differ greatly between individual ICUs. This paper lists the oral care measures most commonly performed in ICUs, indicating their advantages and disadvantages. Brushing with regular toothbrush and rinsing with chlorhexidine are considered optimal measures of oral hygiene in critically ill patients. To date, there is no definitive agreement about the most effective oral care protocol, but evidence demonstrates that consistent performance of oral care may lower the incidence of VAP in critically ill patients.

Direct assessment as a measure of institutional effectiveness in a dental hygiene distance education program.  


This ten-year, longitudinal examination of a dental hygiene distance education (DE) program considered student performance on standard benchmark assessments as direct measures of institutional effectiveness. The aim of the study was to determine if students face-to-face in a classroom with an instructor performed differently from their counterparts in a DE program, taking courses through the alternative delivery system of synchronous interactive television (ITV). This study used students' grade point averages and National Board Dental Hygiene Examination scores to assess the impact of ITV on student learning, filling a crucial gap in current evidence. The study's research population consisted of 189 students who graduated from one dental hygiene program between 1997 and 2006. One hundred percent of the institution's data files for these students were used: 117 students were face-to-face with the instructor, and seventy-two received instruction through the ITV system. The results showed that, from a year-by-year perspective, no statistically significant performance differences were apparent between the two student groups when t-tests were used for data analysis. The DE system examined was considered effective for delivering education if similar performance outcomes were the evaluation criteria used for assessment. PMID:25281680

Daily Food Checklist

The daily food checklist method is a form of food record. The tool is comprised of a list of foods; over the course of a day, a respondent makes a check beside a food each time she or he eats it. The checklist shares an advantage of other record methods in that it does not rely on memory. In addition, it avoids some disadvantages of complete quantitative food records in that it has relatively low respondent and investigator burden.


Physician ‘defiance’ towards hand hygiene compliance: Is there a theory–practice–ethics gap?  

PubMed Central

Background The theory–practice gap has always existed [1,2]. This gap is often cited as a culmination of theory being idealistic and impractical, even if practical and beneficial, is often ignored. Most of the evidence relating to the non-integration of theory and practice assumes that environmental factors are responsible and will affect learning and practice outcomes, hence the gap. Therefore, the author believes that to ‘bridge the gap’ between theory and practice, an additional dimension is required: ethics. A moral duty and obligation ensuring theory and practice integrate. In order to effectively implement new practices, one must deem these practices as worthy and relevant to their role as healthcare providers (HCP). Hence, this introduces a new concept which the author refers to as the theory–practice–ethics gap. This theory–practice–ethics gap must be considered when reviewing some of the unacceptable outcomes in healthcare practice [3]. The literature suggests that there is a crisis of ethics where theory and practice integrate, and healthcare providers are failing to fulfill our duty as patient advocates. Hypothesis Physician hand hygiene practices and compliance at King Abdulaziz Cardiac Centre (KACC) are consistent with those of other physicians in the global healthcare arena. That is one of noncompliance to King Abdulaziz Medical City (KAMC) organizational expectations and the World Health Organization (WHO) requirements? Methods An observational study was conducted on the compliance of cardiac surgeons, cardiologists and nurses in the authors’ cardiac center from January 2010 to December 2011. The hand hygiene (HH) compliance elements that were evaluated pertained to the WHO’s five moments of HH recommendations. The data was obtained through direct observation by KAMC infection prevention and control practitioners. Results Physician hand hygiene compliance at KACC was consistently less than 60%, with nurses regularly encouraging physicians to be diligent with hand hygiene practices in the clinical area. Conclusion Hand hygiene compliance will not improve unless evidence-based recommendations are adopted and endorsed by all healthcare professionals and providers. PMID:24174860

Impact of feed restriction on health, digestion and faecal microbiota of growing pigs housed in good or poor hygiene conditions.  


Feed restriction could be a relevant strategy to preserve gut health, reduce systemic inflammatory response and finally limit antibiotic use. This study assessed the effect of feed restriction on growing pigs submitted to a moderate inflammatory challenge induced by the degradation of the environmental hygiene that is known to alter growth rate. The experiment was run on 80 pigs selected at 7 weeks of age according to a 2×2 factorial design: two feeding levels, ad libitum (AL) and feed restricted (FR) at 60% of AL, and two conditions of environmental hygiene, clean and dirty. Pigs were housed individually throughout the experiment. From 61 to 68 days of age (day 0 to 7), pigs were housed in a post weaning unit and feed restriction was applied to half of the pigs from day 0 to day 29. At 68 days of age (day 7 of the experiment), pigs were transferred in a growing unit where half of FR and half of AL pigs were housed in a dirty environment (poor hygiene) and the other half in a clean environment (good hygiene) until day 42. Growth performance was recorded weekly. Blood and faeces samples were collected to measure indicators of inflammation, nutrient digestibility and microbiota composition. Faecal consistency was monitored daily to detect diarrhoeas. Feed restriction decreased daily weight gain (-35% to -50%, P<0.001), increased the feed conversion ratio (+15%, P<0.001) and CP digestibility (+3%, P<0.05) and reduced the occurrence of diarrhoeas irrespective of hygiene conditions. Poor hygiene conditions decreased growth performance (-20%, P<0.05) and total tract digestibility of all nutrients (P<0.001). Haptoglobin (+50%) concentrations and lymphocyte (+10%) and granulocyte (+40%) numbers were higher in poor hygiene conditions (P<0.05), confirming that the model was effective to induce a systemic inflammatory response. Both feed restriction and hygiene modified the profile of the faecal microbiota. In this study, feed restriction did not reduce the systemic inflammatory response caused by poor hygiene conditions despite the limitation of the occurrence of digestive disorders. However, our study opens discussions regarding the impact of hygiene and feed restriction on gut microbial communities and digestive health. PMID:24963640

Radioactivity and food  

SciTech Connect

Two topics relating to radioactivity and food are discussed: food irradiation for preservation purposes, and food contamination from radioactive substances. Food irradiation involves the use of electromagnetic energy (x and gamma rays) emitted by radioactive substances or produced by machine in order to destroy the insects and microorganisms present and prevent germination. The sanitary and economic advantages of treating food in this way are discussed. Numerous studies have confirmed that under strictly controlled conditions no undesirable changes take place in food that has been irradiated nor is radioactivity induced. Reference is made to the accident at the Chernobyl nuclear power station, which aroused public concern about irradiated food. The events surrounding the accident are reviewed, and its consequences with regard to contamination of different foods with radioactive substances, particularly iodine-131 and cesium-137, are described. Also discussed are the steps that have been taken by different international organizations to set limits on acceptable radioactivity in food.15 references.

Is fast food addictive?  


Studies of food addiction have focused on highly palatable foods. While fast food falls squarely into that category, it has several other attributes that may increase its salience. This review examines whether the nutrients present in fast food, the characteristics of fast food consumers or the presentation and packaging of fast food may encourage substance dependence, as defined by the American Psychiatric Association. The majority of fast food meals are accompanied by a soda, which increases the sugar content 10-fold. Sugar addiction, including tolerance and withdrawal, has been demonstrated in rodents but not humans. Caffeine is a "model" substance of dependence; coffee drinks are driving the recent increase in fast food sales. Limited evidence suggests that the high fat and salt content of fast food may increase addictive potential. Fast food restaurants cluster in poorer neighborhoods and obese adults eat more fast food than those who are normal weight. Obesity is characterized by resistance to insulin, leptin and other hormonal signals that would normally control appetite and limit reward. Neuroimaging studies in obese subjects provide evidence of altered reward and tolerance. Once obese, many individuals meet criteria for psychological dependence. Stress and dieting may sensitize an individual to reward. Finally, fast food advertisements, restaurants and menus all provide environmental cues that may trigger addictive overeating. While the concept of fast food addiction remains to be proven, these findings support the role of fast food as a potentially addictive substance that is most likely to create dependence in vulnerable populations.

A qualitative study of senior hospital managers¿ views on current and innovative strategies to improve hand hygiene.  


BackgroundDespite universal recognition of the importance of hand hygiene in reducing the incidence of healthcare associated infections, health care workers¿ compliance with best practice has been sub-optimal. Senior hospital managers have responsibilities for implementing patient safety initiatives and are therefore ideally placed to provide suggestions for improving strategies to increase hand hygiene compliance. This is an under-researched area, accordingly the aim of this study was to identify senior hospital managers¿ views on current and innovative strategies to improve hand hygiene compliance.MethodsQualitative design comprising face-to-face interviews with thirteen purposively sampled senior managers at a major teaching and referral hospital in Sydney, Australia. Data were analysed thematically.ResultsSeven themes emerged: culture change starts with leaders, refresh and renew the message, connect the five moments to the whole patient journey, actionable audit results, empower patients, reconceptualising non-compliance and start using the hammer.ConclusionsTo strengthen hand hygiene programmes, strategies based on the five moments of hand hygiene should be tailored to specific roles and settings and take into account the whole patient journey including patient interactions with clinical and non-clinical staff. Senior clinical and non-clinical leaders should visibly champion and mandate best practice initiatives and articulate that hand hygiene non-compliance is culturally and professionally unacceptable to the organization. Strategies that included a disciplinary component and which conceptualise hand hygiene non-compliance as a patient safety error may be worth evaluating in terms of staff acceptability and effectiveness.

Food Service System  

NASA Technical Reports Server (NTRS)

The 3M Food Service System 2 employs a "cook/chill" concept for serving food in hospitals. The system allows staff to prepare food well in advance, maintain heat, visual appeal and nutritional value as well as reducing operating costs. The integral heating method, which keeps hot foods hot and cold foods cold, was developed by 3M for the Apollo Program. In the 1970s, the company commercialized the original system and in 1991, introduced Food Service System 2. Dishes are designed to resemble those used at home, and patient satisfaction has been high.

Food Antimicrobials Nanocarriers  

PubMed Central

Natural food antimicrobials are bioactive compounds that inhibit the growth of microorganisms involved in food spoilage or food-borne illness. However, stability issues result in degradation and loss of antimicrobial activity. Nanoencapsulation allows protection of antimicrobial food agents from unfavorable environmental conditions and incompatibilities. Encapsulation of food antimicrobials control delivery increasing the concentration of the antimicrobials in specific areas and the improvement of passive cellular absorption mechanisms resulted in higher antimicrobial activity. This paper reviews the present state of the art of the nanostructures used as food antimicrobial carriers including nanoemulsions, nanoliposomes, nanoparticles, and nanofibers. PMID:24995363

Overview of Evidence in Prevention and Aetiology of Food Allergy: A Review of Systematic Reviews  

PubMed Central

The worldwide prevalence of food allergy appears to be increasing. Early life environmental factors are implicated in the aetiology of this global epidemic. The largest burden of disease is in early childhood, where research efforts aimed at prevention have been focused. Evidence synthesis from good quality systematic reviews is needed. We performed an overview of systematic reviews concerning the prevention and aetiology of food allergy, retrieving 14 systematic reviews, which covered three broad topics: formula (hydrolysed or soy) for the prevention of food allergy or food sensitization; maternal and infant diet and dietary supplements for the prevention of food allergy or food sensitization and hygiene hypothesis-related interventions. Using the AMSTAR criteria for assessment of methodological quality, we found five reviews to be of high quality, seven of medium quality and two of low quality. Overall we found no compelling evidence that any of the interventions that had been systematically reviewed were related to the risk of food allergy. Updating of existing reviews, and production of new systematic reviews, are needed in areas where evidence is emerging for interventions and environmental associations. Furthermore, additional primary studies, with greater numbers of participants and objective food allergy definitions are urgently required. PMID:24192789

Labeling of ethnic food in the Prato Chinese community.  


Ethnic food consumption is a quickly growing reality within Chinese communities, which have a well-organized "internal" food market for both Asian and ethnic foods produced in the European Union. The main problems associated with these markets are related to hygienic conditions, certifications of accomplishment, and personnel management. Moreover, controls and identification of the products are difficult because of cultural and linguistic barriers. In this study, five markets managed by the Chinese were visited, and the conformity of the reported label information found on different kinds of food (prepackaged or loose) was assessed by a collaboration between the Local Authorities of Control of the Prato territory, which hosts the largest Chinese community in Italy, and of native speakers of Chinese. All visited markets presented products (n = 75) with non-conformities: lack of translation (6%) and incomplete/mistaken translation of the commercial name (72%) and place of production (12%). In addition to the legal implications of the observed non-compliances, certain sanitary issues were taken into consideration. In fact, a number of the products that belong to risk categories could be misclassified in a non-risk category. Lastly, missing ingredients or complete alteration of their commercial names may represent health threats in cases of allergen ingestion by allergic or intolerant consumers. PMID:20437095

Studies on bacteriocinogenic Lactobacillus isolates from selected Nigerian fermented foods.  


Ten bacteriocin-producing (bacteriocinogenic) Lactobacillus isolates obtained from three Nigerian fermented foods namely: kenkey, ogi and wara were tested against the following indicator organisms: Lactobacillus plantarum and food borne pathogens comprising enterotoxigenic Escherichia coli, enterohaemorrhagic Escherichia coli, Serratia, Pseudomonas, Vibrio cholerae, Aeromonas sobria, Aeromonas cavice, Salmonella typhimurium, Plesiomonas shigelloides and Staphylococcus aureus. All the bacteriocinogenic Lactobacillus were found to inhibit L. plantarum while some inhibited some of the food borne pathogens listed above. The antimicrobial activities of bacteriocins from L. plantarum KKY12 and L. casei OGM12 were caused by proteins detectable in the culture liquids. They are designated Plantacin N and Caseicin A and they have narrow antimicrobial spectra. Plantacin N from L. plantarum KKY12 was active against L. plantarum, Pseudomonas, Aeromonas sobria and Aeromonas cavice whereas Caseicin A from L. casei OGM12 inhibited L. plantarum, enterotoxigenic Escherichia coli and Vibrio cholerae. Caseicin A is stable at 121 degrees C/15 mins, and both are inactivated by proteolytic enzymes. The bacteriocinogenic properties of the local isolates of Lactobacillus can help to reduce hygienic risk and the spoilage of fermented foods. PMID:8568643

Appraisal of hygiene indicators and farming practices in the production of leafy vegetables by organic small-scale farmers in uMbumbulu (Rural KwaZulu-Natal, South Africa).  


During October, November and December 2011 (when highest sales of Agri-Hub fresh produce are observed), irrigation water, compost, lettuce and spinach sampled from four different farmer cooperatives supplying the local Agri-Hub in uMbumbulu (KwaZulu-Natal, South Africa) were analyzed monthly for the presence of total and fecal coliforms and Escherichia coli using the most probable number (MPN) technique. The pH values for all irrigation water samples analyzed were within the acceptable range of 6.5-8.5 for agricultural use. Fecal coliform levels were <1,000 MPN per 100 mL irrigation water and <1,000 MPN per g of compost. The vegetables produced by Agri-Hub small-scale farmers met the requirements for total coliforms of <200/g set by the South African Department of Health at the time of sampling. E. coli MPN values for irrigation water and vegetables were below the limit of detection. In addition, the farming practices of 73 farmers were assessed via a survey. The results revealed that more than 40% of farmers used microbiologically safe tap water for irrigation and that trained farmers have a significantly better understanding of the importance of production hygiene than untrained farmers. These results reiterate the importance of interventions that build capacity in the area of food safety and hygiene of small-scale farmers for market access of formal value chains. PMID:24065036

Overview of e-Bug: an antibiotic and hygiene educational resource for schools.  


Antibiotic resistance is an increasing community problem and is related to antibiotic use. If antibiotic use could be reduced, the tide of increasing resistance could be stemmed. e-Bug is a European project involving 18 European countries, partly funded by The Directorate-General for Health and Consumers (DG SANCO) of the European Commission. It aims to develop and disseminate across Europe a junior and senior school teaching pack and web site (hosting the lesson plans and complementary games) that teach young people about prudent antibiotic use, microbes, transmission of infection, hygiene and vaccines. The aim of e-Bug is to increase young people's understanding, through enjoyable activities, of why it is so important to use antibiotics correctly in order to control antibiotic resistance, and to have good hand and respiratory hygiene to help reduce the spread of infection. Within the senior school pack the sexual transmission of infections has also been included, as the peak age of chlamydial infection is in 16-24 year olds. Teachers, young people and the consortium of 18 countries were closely involved with agreeing learning outcomes and developing the resource activities. Young people helped create the characters and microbe artwork. The resources have been translated, adapted for and disseminated to schools across 10 countries in Europe, and endorsed by the relevant government departments of health and education. The web site has been accessed from >200 countries. The resources will be translated into all European Union languages, and have been used to promote European Antibiotic Awareness Day and better hand and respiratory hygiene during the influenza pandemic in 2009.

Prospective technologies and equipment for sanitary hygienic measures for life support systems  

NASA Astrophysics Data System (ADS)

Creation of optimal sanitary hygienic conditions is a prerequisite for good health and performance of crews on extended space missions. There is a rich assortment of associated means, methods and equipment developed and experimentally tested in orbital flights. However, over a one-year period a crew of three uses up about 800 kg of ground-supplied wet wipes and towels for personal needs. The degree of closure of life support systems for long-duration orbital flights should be maximized, particularly for interplanetary missions, which exclude any possibility of re-supply. Washing with regenerated water is the ultimate sanitary hygienic goal. That is why it is so important to design devices for crew bathing during long-term space missions. Investigations showed that regeneration of wash water (WW) using membrane processes (reverse osmosis, nanofiltration etc.), unlike sorption, would not require much additional expendables. A two-stage membrane recovery unit eliminated >85% of permeate from real WW with organic and inorganic selectivity of 82 95%. The two-stage WW recovery unit was tested with artificial and real WW containing detergents available for space crews. Investigations into the ways of doing laundry and drying along with which detergents will be the best fit for space flight are also planned. Testing of a technology for water extraction from used textiles using a conventional period of contact of 1 s or more, showed that the humidity of the outgoing air flow neared 100%. Issues related to designing the next generation of space life support systems should consider the benefits of integrating new sanitary hygienic technologies, equipment, and methods.

Expression of Varroa sensitive hygiene (VSH) in commercial VSH honey bees (Hymenoptera: Apidae).  


We tested six commercial sources of honey bees, Apis mellifera L. (Hymenoptera: Apidae), whose breeding incorporated the trait of Varroa sensitive hygiene (VSH). VSH confers resistance to the parasitic mite Varroa destructor Anderson & Trueman by enhancing the ability of the bees to hygienically remove mite-infested brood. VSH production queens (i.e., queens commercially available for use in beekeepers' production colonies) from the six sources were established in colonies which later were measured for VSH. Their responses were compared with those of colonies with three other types of queens, as follows: VSH queens from the selected closed population maintained by USDA-ARS for research and as a source of breeding germplasm, queens from the cooperating commercial distributor of this germplasm, and queens of a commercial, mite-susceptible source. The reduction of mite infestation in brood combs exposed to test colonies for 1 wk differed significantly between groups. On average, colonies with VSH production queens reduced infestation by 44%. This group average was intermediate between the greater removal by pure ARS VSH (76%) and the cooperators' breeding colonies (64%), and the lesser removal by susceptible colonies (7%). VSH production colonies from the different sources had variable expression of hygiene against mites, with average reduced infestations ranging from 22 to 74%. In addition, infertility was high among mites that remained in infested cells in VSH breeder colonies from ARS and the commercial distributor but was lower and more variable in VSH production colonies and susceptible colonies. Commercial VSH production colonies supply mite resistance that generally seems to be useful for beekeeping. Resistance probably could be improved if more VSH drones sources were supplied when VSH production queens are being mated. PMID:21735889

Compliance of healthcare workers with hand hygiene practices in neonatal and pediatric intensive care units: overt observation.  


Background. The objective of this study was to assess the compliance of hand hygiene (HH) of healthcare workers (HCWs) in the neonatal and pediatric intensive care unit in a tertiary university hospital in Istanbul. Methods. An observational study was conducted on the compliance of HH for the five World Health Organization (WHO) indications. HCWs were observed during routine patient care in day shift. The authors also measured the technique of HH through hand washing or hand hygiene with alcohol-based disinfectant. Results. A total of 704 HH opportunities were identified during the observation period. Overall compliance was 37.0% (261/704). Compliance differed by role: nurses (41.4%) and doctors (31.9%) [P = 0.02, OR: 1.504, CI 95%: 1.058-2.137]. HCWs were more likely to use soap and water (63.6%) compared to waterless-alcohol-based hand hygiene (36.3%) [P < 0.05]. Conclusion. Adherence to hand hygiene practice and use of alcohol-based disinfectant was found to be very low. Effective education programs that improve adherence to hand hygiene and use of disinfectants may be helpful to increase compliance. PMID:25525428

Increase of crevicular interleukin 1beta under academic stress at experimental gingivitis sites and at sites of perfect oral hygiene.  


This study analyses the effects of academic stress on crevicular interleukin-1beta(I1-1beta) both at experimental gingivitis sites and at sites of perfect oral hygiene. I1-1beta is thought to play a predominant role in periodontal tissue destruction. 13 medical students participating in a major medical exam (exam group) and 13 medical students not participating in any exam throughout the study period (control group) volunteered for the study. In a split-mouth-design, they refrained from any oral hygiene procedures in two opposite quadrants for 21 days (experimental gingivitis) while they maintained perfect hygiene levels at the remaining sites. Crevicular fluid was sampled for further I1-1beta analysis at teeth 5 and 6 of the upper jaw at days 1, 5, 8, 11, 14, 18 and 21 of the experimental gingivitis period. Exam students showed significantly higher I1-1beta levels than controls both at experimental gingivitis sites (area under the curve, exam group: 1240.64+/-140.07; control group: 697.61+/-111.30; p=0.004) and at sites of perfect oral hygiene (exam group: 290.42+/-63.19; control group: 143.98+/-42.71; p = 0.04). These results indicate that stress might affect periodontal health by increasing local I1-1beta levels especially when oral hygiene is neglected. PMID:9923503

HCWs were more likely to use soap and water (63.6%) compared to waterless-alcohol-based hand hygiene (36.3%) [P < 0.05]. Conclusion. Adherence to hand hygiene practice and use of alcohol-based disinfectant was found to be very low. Effective education programs that improve adherence to hand hygiene and use of disinfectants may be helpful to increase compliance.

[Social and hygienic conditions of family creation and birth of the first child].  


Discusses the problems of public health reformation using the so-called new social contract, put forward in Russia by J. Rice, heading the ZdravReform program. Based on analysis of the socio-hygienic conditions of family creation and birth of the first child, the authors propose the following assumption: creation of a family and appearance of the first child is one factor occupying a special place within the framework of the new social contract and validate this assumption by the data of their sociomedical research.

Industrial Hygiene Concerns during the Decontamination and Decommissioning of the Tokamak Fusion Test Reactor  

SciTech Connect

A significant industrial hygiene concern during the Decontamination and Decommissioning (D and D) of the Tokamak Fusion Test Reactor (TFTR) was the oxidation of the lead bricks' surface, which were utilized for radiation shielding. This presented both airborne exposure and surface contamination issues for the workers in the field removing this material. This paper will detail the various protection and control methods tested and implemented to protect the workers, including those technologies deployed to decontaminate the work surfaces. In addition, those techniques employed to recycle the lead for additional use at the site will be discussed.

Dental caries, gingival health, and oral hygiene of long term survivors of paediatric malignant diseases.  

PubMed Central

Fifty two children who had had cancer and been treated with chemotherapy, and who were long term event free, were examined for caries prevalence, gingival health, and oral hygiene and compared with a control group. A higher dental caries prevalence for the 14-17 year age group was noted. The restorative index was significantly lower in the age group 10-13. There were no significant differences in gingival index, plaque index, or toothbrushing frequency. It is concluded that these patients should be considered as at high risk for caries after cancer treatment. Professional dental follow up should be integrated in the medical follow up. PMID:7702374

Epidemiologic Background of Hand Hygiene and Evaluation of the Most Important Agents for Scrubs and Rubs  

PubMed Central

The etiology of nosocomial infections, the frequency of contaminated hands with the different nosocomial pathogens, and the role of health care workers' hands during outbreaks suggest that a hand hygiene preparation should at least have activity against bacteria, yeasts, and coated viruses. The importance of efficacy in choosing the right hand hygiene product is reflected in the new Centers for Disease Control and Prevention guideline on hand hygiene (J. M. Boyce and D. Pittet, Morb. Mortal. Wkly. Rep. 51:1-45, 2002). The best antimicrobial efficacy can be achieved with ethanol (60 to 85%), isopropanol (60 to 80%), and n-propanol (60 to 80%). The activity is broad and immediate. Ethanol at high concentrations (e.g., 95%) is the most effective treatment against naked viruses, whereas n-propanol seems to be more effective against the resident bacterial flora. The combination of alcohols may have a synergistic effect. The antimicrobial efficacy of chlorhexidine (2 to 4%) and triclosan (1 to 2%) is both lower and slower. Additionally, both agents have a risk of bacterial resistance, which is higher for chlorhexidine than triclosan. Their activity is often supported by the mechanical removal of pathogens during hand washing. Taking the antimicrobial efficacy and the mechanical removal together, they are still less effective than the alcohols. Plain soap and water has the lowest efficacy of all. In the new Centers for Disease Control and Prevention guideline, promotion of alcohol-based hand rubs containing various emollients instead of irritating soaps and detergents is one strategy to reduce skin damage, dryness, and irritation. Irritant contact dermatitis is highest with preparations containing 4% chlorhexidine gluconate, less frequent with nonantimicrobial soaps and preparations containing lower concentrations of chlorhexidine gluconate, and lowest with well-formulated alcohol-based hand rubs containing emollients and other skin conditioners. Too few published data from comparative trials are available to reliably rank triclosan. Personnel should be reminded that it is neither necessary nor recommended to routinely wash hands after each application of an alcohol-based hand rub. Long-lasting improvement of compliance with hand hygiene protocols can be successful if an effective and accessible alcohol-based hand rub with a proven dermal tolerance and an excellent user acceptability is supplied, accompanied by education of health care workers and promotion of the use of the product.

Biosensors for Food Safety  

NSDL National Science Digital Library

How can you tell if harmful bacteria are in your food or water that might make you sick? What you eat or drink can be contaminated with bacteria, viruses, parasites and toxinsâpathogens that can be harmful or even fatal. Students learn which contaminants have the greatest health risks and how they enter the food supply. While food supply contaminants can be identified from cultures grown in labs, bioengineers are creating technologies to make the detection of contaminated food quicker, easier and more effective.
