Adequa??o ?s normas de higiene operacional em unidade de alimenta??o e nutri??o (UAN) / Food handling at a restaurant of governmental educational institution: meeting the standards of operational hygieneGOMEZ, Gilda Maira de Carvalho Barreto Magalh?es 27 July 2012 (has links)
CAPES / The increase in the number of commensals in the Federal Educational Institutes has created a demand for specialized food services to offer safe food. O Campus Monte Castelo of the Federal Institute of Maranh?o (IFMA) opted for an outsourced meal service on trays, self-service and fast food. This study aimed to diagnose the conditions of hygiene and management at the Food and Nutrition Unit (FNU) and develop educational and sanitary hygienic procedures essential to food safety. To do this, two check lists were developed, one to check the management and another to evaluate cleaning procedures and get a diagnostic of the situation. At the same time, microbiological analyzes were performed to verify the quality of air, water, hygiene of utensils and hands of food handlers. Four out of nine sampled environmental sites showed fungal contamination in the air higher than 100 CFU/cm ? / week especially the food preparation environment as a result of the higher temperature and humidity, and an inadequate or broken exhaust/ ventilation. One of the lounge areas of self service meal, next to the bathroom was also classified as nonconforming. With respect to the FNU water potability, it was detected the presence of total coliforms in only one of the drinking troughs, denoting that the procedure for maintenance and cleaning is inappropriate, since the water from the reservatory was potable. The evaluation of the microbial load of the surface of utensils and hands of food handlers was performed before and after implementation of Good Practices, and adoption of Standard Safety Operating Procedures (SOP). At the first evaluation, all surfaces were considered inadequate, with mesophilic counts up 150 CFU per cm2. After the procedures of hygiene adoption, mesophilic counts were reduced by more than one log cycle and only the vegetable cutting plate kept contaminated with more than 5cfu/cm2. The adopted hygiene procedures were not sufficient to completely eliminate total coliform that were detected in two of the utensils, which was related to the fact that they were over-worn and due to biofilm buildup. The contamination of the hands of food handlers with mesophilic microorganisms has been reduced by up to 3,6 log cycles after adoption of hygiene procedures. The total coliform contamination, even though reduced, persisted, which means that these procedures should be improved. However, they are considered satisfactory from the safety point of view, since fecal coliforms and coagulase positive staphylococci were not detected. The procedures established at the FNU, especially the GMPs manual and SOPs procedures resulted in adequacy of most hygiene procedures. For full compliance to the requirements of hygiene a continuous training of handlers is needed. Also inadequacies remain on the infrastructure and management. / O aumento do n?mero de comensais nos Institutos Federais de Educa??o criou uma demanda por servi?o especializado de alimenta??o, visando oferecer alimento seguro. O Campus Monte Castelo do Instituto Federal do Maranh?o (IFMA) optou, por contratar um restaurante terceirizado que oferece servi?o de refei??es em bandejas, self-service e lanchonete. Esse trabalho buscou diagnosticar as condi??es de higiene e gest?o da unidade de alimenta??o e nutri??o (UAN) e desenvolveu praticas educativas de procedimentos higi?nico-sanit?rios essenciais ? inocuidade dos alimentos. Para isso foram desenvolvidos dois check lists sendo um, para caracteriza??o do estabelecimento e dos procedimentos de higieniza??o existentes, e um outro check-list, exclusivo para avalia??o de Boas Praticas de Higiene, foi utilizado para diagnosticar e posteriormente verificar a adequa??o dos procedimentos de higieniza??o. Ao mesmo tempo, foram realizadas analises microbiol?gicas para verificar a qualidade do ar, da ?gua, a higiene dos utens?lios e m?os de manipuladores. Quatro de nove ambientes amostrados apresentaram contamina??o f?ngica no ar maior que 100UFC/cm?/semana especialmente o ambiente de preparo de alimentos por ser local onde a temperatura e umidade s?o elevadas, e ventila??o e exaust?o inadequadas e/ou inoperantes. Uma das ?reas do sal?o de refei??o do self service, pr?xima ao banheiro, tamb?m foi classificada como n?o conforme. Com rela??o ? potabilidade da ?gua da UAN, foi constatada a presen?a de coliformes totais somente em um dos bebedouros, denotando que o procedimento de manuten??o e higieniza??o do bebedouro ? inadequado, j? que a ?gua da caixa mostrou-se pot?vel. A avalia??o da carga microbiana da superf?cie de utens?lios e m?os de manipuladores foi realizada antes e ap?s implanta??o das Boas Pr?ticas, e ado??o de Procedimentos Operacionais Padr?o (POP) de higiene. No primeiro momento todas as superf?cies foram consideradas inadequadas com contagem de mes?filos de at? 150 UFC por cm2. Ap?s ado??o dos procedimentos de higiene houve redu??o de mais de um ciclo logar?tmico na contagem de mes?filos e apenas a placa de corte de folhosas apresentou contamina??o maior que 5 UFC/cm2, valor considerado adequado. Entretanto, os procedimentos de higieniza??o adotados n?o foram suficientes para eliminar totalmente a contamina??o com coliformes totais em dois dos utens?lios, o que foi relacionado ao fato de apresentarem-se desgastados pelo uso intensivo e forma??o de biofilmes A contamina??o com microrganismos mes?filos nas m?os dos manipuladores foi reduzida em at? 3,6 ciclos logar?tmicos ap?s ado??o dos procedimentos de higiene. A contamina??o com coliformes totais, mesmo que reduzida, persistiu, o que significa que estes procedimentos dever?o ser melhorados. Por?m s?o considerados satisfat?rios do ponto de vista sanit?rio, j? que n?o foram encontrados coliformes termotolerantes e estafilococos coagulase positiva. A interven??o feita na UAN, especialmente com a elabora??o do manual das BPFs e de POPs da higieniza??o resultou em adequa??o da maioria dos procedimentos de higiene adotados. Para a total adequa??o aos requisitos de higiene faz-se necess?ria a capacita??o continuada dos manipuladores. Tamb?m persistem inadequa??es relativas ? infra estrutura e gest?o
