Food handlers' lack of knowledge, and misunderstanding of safe food temperatures: An analysis using the theory of social representations.

Comprehension is the ability to understand and be familiar with situations and facts. A critical factor causing foodborne diseases is the inadequate temperature during food storage and handling; food handlers often fail to understand this. Therefore, in this study, we investigated how technical language and everyday knowledge operate in the comprehension of safe food temperatures among food handlers in food services. To achieve this, data collection was carried out in two stages. In the first stage, a survey was conducted to 206 food handlers from 14 food service working in the city of São Paulo. Through this survey, we gathered information to characterize the socio-demographic profile of the sample, details about participation in training, and knowledge of technical terms related to safe food temperatures. In the second stage, individuais interviews were conducted on the same day following the questionnaire administration in each food service. A total of 29 interviews were carried out An interview script was developed containing two storylines based on the Fourth Key: "Keep food at safe temperatures," which is part of the WHO's "Five Keys to Safer Food" manual. Further, the collective subject discourse technique, which is based on the theory of social representations, was employed to analyze each interview and construct a representative collective discourse. Analysis of the results indicated that lack of knowledge about safe food temperatures is mainly a result of the misunderstanding of technical terms. The collective discourses obtained results reinforced that food handlers had diverse and erroneous information about food defrosting, and they exhibited low confidence and clarity about safe food temperatures. Overall, psychological, social, and cultural factors affect the formation of social representations that guide food handlers' decision-making.

Inspeção sanitária dos manipuladores de alimentos no universo Offshore: protagonismo do enfermeiro no cuidado à saúde / Sanitary inspection of food handlers in the offshore universe: the role of nurses in health care / Inspección sanitaria de los manipuladores de alimentos en el universo offshore: protagonismo del enfermero en el cuidado de la salud

Introdução: O universo offshore para o enfermeiro é um campo que se encontra em evidência frente à demanda nos dias atuais. Uma das particularidades desenvolvidas pelo enfermeiro é a fiscalização dos profissionais envolvidos com alimentação e limpeza, que ao passar por inspeções sanitárias respondem ao órgão responsável pela inspeção, atendendo assim legislações da Marinha do Brasil e órgãos federais como a Agência Nacional de Vigilância Sanitária. Logo, por se tratar da minha área de atuação profissional, levantei esse estudo com o propósito de desenvolver um instrumento facilitador para os enfermeiros na realização da avaliação física e higiênica dos manipuladores de alimentos em forma de uma lista de verificação, onde o enfermeiro tenha os pontos necessários para uma avaliação adequada, clara e sem víeis do estado físico desses trabalhadores. Objetivos: Criar uma lista de verificação das condições sanitárias dos manipuladores de alimentos que atuam em unidade de alimentação e nutrição Offshore após identificação na produção científica da área da saúde, literatura/evidências acerca de inspeção sanitária dos trabalhadores com vistas às boas práticas de manipulação de alimentos Método: Para o desenvolvimento do estudo proposto foi utilizada a abordagem qualitativa, o qual se apresenta como de natureza teórica metodológica e descritiva. A pesquisa metodológica trata de investigações dos métodos de obtenção e organização de dados e condução de pesquisas rigorosas. O estudo foi realizado em três etapas, sendo a primeira etapa composta pela realização de uma revisão integrativa, que permitiu identificar na literatura obras que foram analisadas acerca da temática para dar embasamento ao estudo. Na segunda etapa foi realizado um apanhado de informações nas legislações e obras especialistas na área de exame físico com objetivo de criar padrões para a construção de um instrumento de avaliação física e higiênica. Na terceira etapa ocorreu a compactação dos dados levantados para a criação dos padrões, assim possibilitando a criação do instrumento em forma de cheklist (palavra em inglês, considerada um americanismo que significa lista de verificações), podendo assim com esse instrumento nortear os enfermeiros em suas inspeções sanitárias com os manipuladores de alimentos. Resultados: Foi cirado padrões e construido uma lista de verificação para realização das inspeções sanitárias de manipuladores de alimentos em ambiente offshore. Conclusão: Conclui-se que é notória a necessidade de mais estudos acerca da temática afim de estabelecer e deixar mais claro o papel do enfermeiro em uma área que se encontra em expansão e requer profissionais cada vez mais específicos e com aprimoramento como o universo offshore

Introduction: The offshore universe for the nurse is a field that is in evidence in front of the present demand. One of the peculiarities developed by the nurse is the inspection of the professionals involved with food and cleaning, who, when passing through sanitary inspections; respond to the agency responsible for inspection, thus complying with Brazilian Navy legislation and federal agencies such as the National Sanitary Surveillance Agency. Therefore, because it is my area of professional practice. In view of the above, it was defined as a general objective: To prepare a checklist of the physical and hygienic conditions of food handlers operating in the Offshore food and nutrition, and as specific objectives: To identify in scientific production of the health area, literature / evidence on the evaluation / physical- sanitary conditions of workers with a view to good food handling practices and develop an instrument to evaluate the physical and personal hygiene aspects of workers handling food in a food unit and nutrition in an offshore environment based on the scientific literature. Method: For the development of the proposed study the qualitative approach was used, which is presented as a theoretical methodological and descriptive. The methodological research deals with investigations of methods of obtaining and organizing data and conducting rigorous research. They deal with the development, validation and evaluation of tools and research methods. In the methodological study, it often focuses on the development of new instruments, and the goal is the development of a reliable, accurate and usable instrument that can be applied by other researchers and professionals. This study belongs to any scientific discipline, dealing with complex phenomena such as the behavior or health of individuals, such as occurs in nursing research. Methodological research is considered a strategy that systematically uses existing knowledge to elaborate a new intervention or significant improvement of an existing intervention, or to elaborate or improve an instrument, a device or a method of mediation. Results: The study was carried out in three stages, and the first stage consisted of an integrative review, which allowed the identification in the literature of works that were analyzed about the theme to support the study. In the second stage, a collection of information was made in the legislations and expert works in the area of physical examination with the objective of creating standards for the construction of a physical and hygienic evaluation instrument. In the third stage, the data collected for the creation of the standards were compiled, thus enabling the creation of the instrument in the form of a checklist (English, considered an Americanism that means a checklist), so that with this instrument it can guide nurses in their assessments. Results: It was created standards and built a checklist for conducting sanitary inspections of food handlers in an offshore environment. Conclusion: It is concluded that there is a need for more studies about the subject in order to establish and clarify the role of nurses in an expanding area and require more specific and improved professionals such as the offshore universe

Occurrence of non-O157 Shiga toxin-encoding Escherichia coli in artisanal mozzarella cheese in Brazil: risk factor associated with food workers

Abstract Mozzarella cheese is considered a safe food due to the high temperature treatment used in the traditional process of stretching into hot water; however, a post-process contamination during the cheese manufacture or during the processing (before distribution) could occur. This study investigated the occurrence of Shiga toxin-encoding Escherichia coli (STEC) strains in homemade-mozzarella cheese. In total, 59 raw milk cheese samples collected at a local producer in the Jequitinhonha Valley (Northeast of Minas Gerais, Brazil) were submitted for microbiological analysis, and 38 (64.4%) tested positive for E. coli. Then, 147 strains of E. coli were isolated from positive samples and screened by polymerase chain reaction for the presence of the genes encoding the following virulence factors: stx1 and stx 2 (verotoxin types 1 and 2) and eae (intimin). All the isolates were negative for the stx 2, 14 isolates (9.5%) were positive for the stx1 gene, and 11 of them also harbored the eae gene. A food worker was probably involved in cheese contamination during the manufacture schedule. While the development of STEC infection in humans is not completely understood, all STEC- contaminated food can be considered potentially hazardous.

Avaliação das condições higienicossanitárias de lanchonete na cidade de Januária - MG / Evaluation of the sanitary conditions of cafeteria in the city of Januária - MG

As precárias condições de higiene dos locais onde se preparam os alimentos e o pouco conhecimento dos manipuladores sobre as boas práticas de fabricação, contribuem significativamente para o aparecimento das doenças de origem alimentar. Sendo assim, o presente trabalho teve como objetivo avaliar as condições higienicossanitárias em uma lanchonete da cidade de Januária - MG. Para determinar as condições higienicossanitárias do estabelecimento foi utilizada uma lista de verificação (checklist) com base na resolução RDC nº 275 de 21 de outubro de 2002 da ANVISA. Constatou-se que, no geral, o estabelecimento apresentou um percentual de 60,6% no atendimento às Boas Práticas de Fabricação, sendo classificado como "regular" (grupo 2).

Perfil microbiológico do palmito de açaí (Euterpe oleracea Mart. )em conserva e das superfícies envolvidas na sua produção

Nos últimos anos o palmito vem sendo considerado uma iguaria tipicamente brasileira, consumido em diversos Estados como um produto exótico, muito utilizado na elaboração de pratos finos, com demanda não somente no mercado nacional, mas internacional também. Em contrapartida, é considerado um dos principais "vilões" de muitos casos de doenças causadas por alimentos contaminados. Assim, o presente trabalho objetivou avaliar a qualidade microbiológica do palmito de açaí (Euterpe oleracea Mart.) em conserva e das superfícies de contato envolvidas com o processamento do produto, em uma indústria localizada no município de Igarapé- Miri, no Pará. Foram coletadas cinco amostras do palmito de açaí em conserva e da salmoura em que se encontravam os produtos. As coletas foram realizadas em cinco dias diferentes. Todas as análises microbiológicas (Coliformes totais e termotolerantes, Clostridium Sulfito Redutor e Pesquisa de Salmonella spp.) foram realizadas seguindo os métodos oficiais de American Public Health Association. As superfícies analisadas foram: mãos de três manipuladores, bancada, balde, pote de vidro para embalagem, gabarito de corte, placa de corte e faca. As análises realizadas nas superfícies foram: contagem padrão de bactérias aeróbias mesófi- Ias, Coliformes totais e termotolerantes, e contagem de Staphylococcus aureus. Os resultados das análises microbiológicas mostraram que todas as amostras de palmito em conserva e das salmouras encontram-se dentro dos padrões microbiológicos vigentes, portanto em condições adequadas de consumo. As análises microbiológicas de swabs das superfícies mostraram que as superfícies avaliadas não apresentaram contaminação por Coliformes termotoleranteso Observou-se, porém, contagens elevadas de bactérias aeróbias mesófilas e Coliformes totais.[...](AU)

In recent years the palm has been considered a typically Brazilian delicacy, consumed in several States as an exotic product, widely used in the production of fine dishes, becoming a product with demand not only in domestic market but also internationally. However, it is considered one of the "villains" of many cases of diseases caused by contaminated food. Thus, this study aimed to evaluate the microbiological quality açai palm heart (Euterpe oleracea Mart.) Canned and contact surfaces involved in product processing, in an industry in the municipality of Igarapé-Miri, Para. Were collected five açai palm samples preserved and brine they were in the products. Samples were coliected on five different days. Ali microbiological analyzes (Total and Thermotolerant Coliforms, Clostridium Sulfite Reducer and Research Salmonella spp.) Were performed following the official methods of the American Public Health Association. The areas analyzed were the hands of three handlers, bench, bucket, glass jar for packaging, cutting template, cutting board and knife. The analyzes carried out on the surfaces were standard count mesophilic aerobic bacteria, Total and Thermotolerant Coliforms, and count Staphylococcus aureus. The results of these analyzes showed that all samples palm preserves and pickles are within agreed microbiological standards, so in appropriate conditions of use. Microbiological analysis of "swabs" from surfaces showed that the assessed surfaces were not contaminated by Coliform Thermotolerant. However, there was high counts of mesophilic aerobic bacteria and Total Coliform.[...](AU)

Comida de rua: avaliação das condições higiênico-sanitárias de manipuladores de alimentos / Street food: analysis of hygienic and sanitary conditions of food handlers

Resumo O consumo de alimentos de rua é uma alternativa econômica e prática para a população. No entanto, as preocupações sobre a segurança destes alimentos são cada vez maiores. Assim, este estudo teve como objetivo analisar as condições higiênico-sanitárias do comércio ambulante de alimentos em Uberaba-MG. Para isso, além da aplicação de um questionário em 30 pontos de comércio ambulante, foram realizadas também análises microbiológicas nas mãos dos manipuladores e nas superfícies dos recipientes que acondicionam os alimentos. Os achados mostraram baixa adequação dos ambulantes em relação às condições de higiene de mãos e superfícies em contato com os alimentos. Nas superfícies, os resultados para microrganismos aeróbios mesófilos mostraram que apenas 23,3% apresentavam condições satisfatórias de limpeza. O nível de contaminação das mãos por coliformes termotolerantes e/ou Staphylococcus coagulase positiva foi insatisfatório em aproximadamente 47% dos manipuladores. Conclui-se que as condições higiênico-sanitárias de vendedores ambulantes de alimentos em Uberaba são deficientes. Portanto, é urgentemente necessária a adoção de programas eficazes e permanentes de treinamento em segurança alimentar para os manipuladores de alimentos.

Abstract The consumption of street food is an economical and practical alternative for the population. However, concerns regarding the safety of these foods are increasing. Thus, this study aimed to analyze the hygienic and sanitary conditions of the street food trade in Uberaba in the State of Minas Gerais. For this purpose, 30 street vending sites were evaluated using a structured questionnaire and microbiological analysis of food handlers’ hands and food contact recipients and surfaces. The findings showed low adequacy of street food regarding hand hygiene and food contact surfaces. With respect to surfaces, the results for mesophilic aerobic microorganisms revealed that only 23.3% had satisfactory sanitary conditions. The level of contamination of hands by fecal thermotolerant coliforms and/or Coagulase positive Staphylococci was unsatisfactory in approximately 47% of food handlers. The conclusion drawn is that the hygienic and sanitary conditions of food handlers in Uberaba are poor. It is therefore necessary to adopt effective and permanent training programs on food safety for food handlers urgently.

The existence of optimistic bias about foodborne disease by food handlers and its association with training participation and food safety performance.

A positive outlook regarding future events, in which individuals find themselves less likely than others to experience negative events, is called optimistic bias (OB). The aims of this study were: 1. To ascertain the existence and measure the OB phenomenon in food handlers in relation to foodborne disease and 2. To examine the association of OB with food handlers' risk perceptions, knowledge, attitudes, self-reported practices, training participation, food safety performance of the establishments and microbiological analysis. This study examined different food businesses in Santos city, in Brazil, as follows: street food kiosks, beach kiosks, restaurants, hospitals, and school meal services. The food handlers indicated their own risk and their peers' risk of causing a foodborne disease. Responses were given on a 10cm linear scale anchored with descriptors of intensity ranging from "none" to "very high". The difference between these risk perceptions characterized a score of tendency of an OB. A structured questionnaire was administered to evaluate knowledge, attitudes, self-reported practices and food safety performance. A total of 183 food handlers participated in the study. Microbiological analyses were conducted with ready-to-eat foods/preparations from selected sites. The food handlers perceived themselves as less likely than their peers to cause a foodborne disease (p<0.001), demonstrating the tendency of an OB. Food handlers who had undergone some training presented lower scores for the perceived risk of themselves being responsible for a foodborne disease and higher knowledge than did untrained individuals. Hospitals, schools and restaurants performed better than street food group considering food safety performance. However, microorganisms were found in food samples from hospitals. This result may be motivated by OB and other subjective factors. Apparently, this positive outlook of food handlers is associated with training participation, lethality perception and correlating positively with age. No association was found between OB scores and knowledge, attitudes and self-reported practices. Since OB may lead individuals to adopt inappropriate or dangerous behavior, strategies for debiasing food handlers should be designed.

Higiene na manipulação de lanches no comércio ambulante de alimentos / Hygiene in handling of snacks at food street

The sale of snacks on public roads may pose health risk to consumers, the ease of contamination and poor hygiene of food handlers. The aim of this study was to evaluate the conditions of hygiene in the handling of snacks at the food street vendors in central city of Taubaté. We analyzed 16 outlets selling snacks and 22 people who worked there. Only eight (36.4%) handlers performed periodic medical examinations and 12 (54.5%) reported having carried out training of food handling. The 22 (100%) food handlers know the situations in which they should wash their hands, however, is difficult due to lack of appropriate location, in 75% of the points of sale of snacks available there was no bathroom, there was no drinking water 12 (75%) point of sale, the dish towel was used for several functions in 14 (87.5%) stands for snacks and in 12 (75%) were offered the sauces in tubes of repeated use, handling money and food occurred in 17 (77.3%) individuals. Only 1 (10%) snack cart was removed from the flow of vehicles and people, provide other possible cross-contamination risks. Based on these results we can say that the hygiene conditions of the street vending of snacks in Taubaté, SP are inadequate, and thus can present a risk to consumer health. (AU)

A venda de lanches em vias públicas pode representar risco à saúde dos consumidores, pela facilidade de contaminação e falta de higiene dos manipuladores. O objetivo desse trabalho foi avaliar as condições da higiene na manipulação de lanches no comércio ambulante de alimentos na região central do município de Taubaté, SP. Foram avaliados 16 pontos de venda de lanches e 22 pessoas que trabalhavam nesses locais. Apenas 8 (36,4%) manipuladores realizavam exames médicos periódicos e 12 (54,5%) relataram ter realizado treinamento de manipulação de alimentos. Os 22 (100%) manipuladores disseram conhecer as situações em que se deve lavar as mãos, porém, há dificuldade devido a ausência de local apropriado; em 75% dos pontos de comercialização de lanches não havia banheiro disponível; não havia água potável em 12 (75%) locais; o pano de prato era utilizado para varias funções, em 14 (87,5%) carrinhos de lanches; em 12 (75%) os molhos eram oferecidos em bisnagas de uso repetido; a manipulação de dinheiro e alimento ocorria com 17 (77,3%) indivíduos. Apenas 1(10%) carrinho de lanche estava afastado do fluxo de veículos e pessoas, os demais proporcionam possíveis riscos à contaminação cruzada. Diante dos resultados obtidos pode-se dizer que as condições de higiene do comércio ambulante de lanches em Taubaté, SP, estão inadequadas, podendo assim apresentar risco à saúde do consumidor. (AU)

By geographical division of the city, a sample of 15 households per neighborhood was chosen, totaling 615 households. For the diagnosis of the profile of handlers in the households, a questionnaire was prepared, containing 6 open questions and 13 closed questions related to personal data including gender, marital status, education, occupation and monthly income. Issues such as the frequency with which people prepare meals in the households and satisfaction in preparing them, as well as participation in courses and the perception of food safety, were also addressed. It was found that 92.5% of the food handlers were female, 52.2% had complete or incomplete primary school and 35.4% had a monthly income of between 3 and 9 minimum wages. Among those interviewed, 82.6% reported that they prepare meals every day of the week and 77.9% reported that they never had problems caused by the food produced at home. It is important to evaluate the profile of food handlers in the households, as this makes it possible to develop strategies to prevent or diminish foodborne diseases.

Prevalence of ittestinal parasites among food handlers in western Iann / La prevalencia de parasitos intestinales entre los manipuladores de alimentos en el oeste de Iran

Parasitic infection is one of the problems that affect human health, especially in developing countries. In this study, all of the fast food shops, restaurants, and roast meat outlets of Khorramabad (Western Iran) and all the staff employed by them, some 210 people, were selected through a census and their stools were examined for the presence of parasites. The parasitological tests of direct wet-mount, Lugol's iodine staining, formaldehyde-ether sedimentation and Trichrome staining techniques were performed on the samples. The data was analyzed with a chi-square test and logistic regression was selected as the analytical model. The results showed 19 (9%) stool specimens were positive for different intestinal parasites. These intestinal parasites included Giardia lamblia 2.9%, Entamoeba coli 4.3%, Blastocystis sp. 1.4%, and Hymenolepis nana 0.5%. There was a significant difference between the presence of a valid health card, awareness of transmission of intestinal parasites, participation in training courses in environmental health with intestinal parasites (p < 0.05). No statistically significant difference was found between the rate of literacy and gender among patients infected with intestinal parasites (p > 0.05). To control parasitic infection in food handlers, several strategies are recommended such as stool examinations every three months, public education, application of health regulations, controlling the validity of health cards and training on parasitic infection transmission. In this regard, the findings of the present study can be used as a basis to develop preventive programs targeting food handlers because the spread of disease via them is a common problem worldwide.

Infección parasitaria es uno de los problemas de salud humana, especialmente en los países en desarrollo. En este estudio, todas las tiendas de comida rápida, restaurantes, y tiendas de carne asada en Khorramabad (oeste de Irán) y todo el personal que trabaja en ellos, incluyendo 210 personas fueron seleccionadas a través de los censos y las heces fueron examinadas para detectar la presencia de parásitos. La prueba parasitológica directa de mojado de montaje, la tinción de Lugol's yodo, sedimentación formaldehído-éter y tricrómicas técnicas de tinción se realizaron sobre las muestras. Los datos fueron analizados con la prueba de chi-cuadrado y regresión logística seleccionado como el modelo analítico. Los resultados mostraron 19 (9%) muestras de heces fueron positivos para diferentes parásitos intestinales. Los parásitos intestinales incluyen Giardia lamblia 2.9%, Entamoeba coli 4.3%, Blastocystis sp. 1.4%, Hymenolepis nana 0.5%. Hubo diferencia significativa entre la presencia de la tarjeta sanitaria válida, el conocimiento de la transmisión de los parásitos intestinales, la participación en cursos de formación en materia de salud ambiental con parásitos intestinales (p < 0.05). No hubo diferencia estadísticamente significativa entre la tasa de alfabetización y el sexo entre los pacientes infectados con parásitos intestinales (p > 0.05). Para controlar la infección parasitaria en los manipuladores de alimentos se recomiendan varias estrategias, tales como examen de heces cada tres meses, la educación pública, se aplican las normas sanitarias, el control de validez de la tarjeta sanitaria y la transmisión formación infección parasitaria. En este sentido, los resultados del presente estudio se pueden utilizar como una base para desarrollar programas de prevención dirigidos a los manipuladores de alimentos debido a la propagación de enfermedades a través de ellos es un problema común en todo el mundo.

Prevalencia de parásitos intestinales en manipuladores de alimentos en una comunidad rural de Cojedes, Venezuela / Prevalence of intestinal parasites in food handlers in a rural community in Cojedes, Venezuela

La parasitosis intestinales constituyen un problema de salud pública, por la elevada prevalencia que muestran, donde los manipuladores de alimentos parasitados, se convierten en potenciales fuentes de infección, pues algunas formas se transmiten directamente de la fuente de infección al susceptible, por vía fecal-oral. A esto se suma el incremento en el consumo de comida fuera del núcleo familiar, en residentes de zonas urbanas y rurales. El objeto es recolectar información para que las autoridades sanitarias implementen programas de salud acordes a cada región. Métodos: estudio descriptivo, de campo y transversal. Fueron 64 los manipuladores de alimentos, pero la muestra fue de 50. Se aplicó un cuestionario sobre prácticas higiénicas en la manipulación de alimentos, se denominó nivel socioeconómico y prevalencia de parasitosis por ensayos coproparasitológicos. Resultados: fueron 4 mujeres y 6 hombres; un 52 por ciento pertenecía al estrato IV;la mayoría conocía las prácticas higiénicas en la manipulación de alimentos, pero un 26 por ciento tenía alguna parasitosis intestinal; los parásitos más frecuentes fueron: E. nana (41,2 por ciento) y B. hominis (38,7 por ciento); el monoparasitismo fue el 54 por ciento. Conclusión: en la presencia y frecuencia de una enfermedad parasiaria intestinal intervienen diversos factores. Por lo tanto, en manipuladores de alimentos, la educación ajustada al entorno, en buenas prácticas de higiene, es básica para prevenir la transmisión...

Detection of enterotoxin genes of Staphylococcus sp isolated from nasal cavities and hands of food handlers

Food handlers, an important factor in food quality, may contain bacteria that are able to cause foodborne disease. The present study aimed to research coagulase-negative (CNS) and -positive staphylococci (CPS) in 82 food handlers, analyzing nasal and hand swabs, with identification of 62 CNS (75.6 percent) and 20 CPS strains (24.4 percent). Staphylococcal enterotoxins genes were investigated by PCR. In 20 CPS strains, 19 were positive for one or more genes. The percentage of CNS presenting genes for enterotoxins was high (46.8 percent). Despite of the staphylococcal species, the most common gene was sea (35.4 percent), followed by seh and sej (29.2 percent). The detection of new staphylococcal enterotoxins (SEs) genes showed a higher pathogenic potential in this genus. The presence of these gene points out the importance of CNS not only as contaminant bacteria but also as a pathogen.

Identificação de portadores de Staphylococcus enterotoxigênicos e avaliação da sensibilidade a antimicrobianos / Identification of enterotoxigenic Staphylococcus carriers and antimicrobial susceptibility evaluation

This study identified Staphylococcus aureus carriers among students of nutrition course, evaluating the capacity of producing staphylococcal enterotoxins (VIDAS Kit) and also the antimicrobial susceptibility (Kirby-Bauer method) of the isolates. Among 173 students sampled, 62 (35.8%) were detected as carriers of S. aureus, being 38 (61.3%) in nostrils; nine (14.5%) on the hands, and 15 (24.2%) in both sites. The production of staphylococcal toxins was detected in 71.4% of the positive-coagulase pools and in 7.1% of the negative-coagulase pools. Even though considerable resistance had been observed with azithromycin (38%), erithromycin (36%), and tetracycline (14%); cephalothin, cefoperazone, ceftriaxone, ciprofloxacin, imipenem, and oxacillin were effective to inhibit the microorganism growth. The high score of healthy carriers was alarming; however, many of the isolated Staphylococcus showed sensitive to most of the antimicrobial tested. The production of toxins was also relevant, mainly by strains that the current Brazilian legislation consider harmless. (AU)

Conhecimento sobre boas práticas por parte dos manipuladores de alimentos na rede municipal de ensino Botucatu, SP / Knowledge about good practices of food handlers in the municipal education - Botucatu, SP

Quando grandes quantidades de alimentos são preparadas, como na merenda escolar, aumentam-se os perigos microbiológicos caso ocorra uma manipulação inadequada dos mesmos. Neste contexto, o manipulador é um elo indiscutível na cadeia epidemiológica da intoxicação alimentar, o que o torna um elemento incisivo no processo de disseminação de patógenos. O conhecimento dos manipuladores sobre as boas práticas de manipulação da merenda escolar em 4 escolas municipais de Botucatu, SP, por meio de checklist, mostrou as práticas higiênicas adotadas na distribuição dos alimentos. Constatou-se elevado grau de incapacitação do profissional no exercício de sua função, o que reflete a necessidade urgente de treinamento seguido de uma supervisão periódica, a fim de que se tenha como resultado uma distribuição segura de alimentos às crianças beneficiadas.(AU)

In large-scale food preparation, sulci as for a school meal, there are expressive microbiological hazards if the food is not correctly handled. Thus the food handler is unquestionably a link in the food poisoning epidemiological chain, thus becoming an incisive component in a pathogen dissemination process. The food handlers' knowledge of good school meal practices were estimated through a checklist, which implicated 4 public elementary schools in Botucatu, SP. The results showed the food distribution sanitary practices, confirming a high degree of professional incapacitation for the job. These data point to an urgent necessity for training, followed by periodic supervisionin order to obtain safe food distribution to the helped children. (AU)
