Sanitization is considered as essential for the microbial control of vegetables. The aim of this study was to evaluate the sanitization procedures used in commercial restaurants located in Vitória, Brazil. The efficacy of these sanitization procedures in reducing the presence of natural microbiota and Salmonella enterica Enteritidis cells on tomatoes were evaluated. All the restaurants in this study applied the sanitization methods using containers for diluting the sanitization solution. After the sanitization treatments, a reduction in mesophilic aerobic counts, yeasts, moulds and S. enterica occurred in all the treatments. A higher reduction in microorganisms was observed after treatment with 2% acetic acid. There was no significant difference between tomatoes treated with a sodium dichloroisocyanurate solution and sodium hypochlorite for all microorganisms which were evaluated. Chlorinated compounds are the most used products but a limitation in microbial inactivation was observed in this study.
O controle das condições higienicossanitárias em restaurantes é tarefa árdua, pois a contaminação pode ocorrer em diferentes etapas do preparo dos alimentos. Objetivou-se avaliar as Boas Práticas de Manipulação e a contaminação microbiológica de ambientes e de superfícies de preparo em restaurantes comerciais de Vitória, ES. A pesquisa foi realizada de fevereiro a maio de 2015, e na primeira etapa foi feita a avaliação de Boas Práticas por meio de lista de verificação baseada na Resolução RDC 216/2004. Na segunda etapa foram coletas amostras do ar e de superfícies de preparo e de utensílios. O percentual de adequação aos itens avaliados nos restaurantes (n=8) variou de 39,59 % a 83,61 %. Três restaurantes apresentaram de 76 a 100 % e quatro de 51 a 75 % de atendimento aos itens. As contagens médias de mesófilos aeróbios e fungos filamentosos e leveduras no ar estavam acima de 30 UFC/cm2 /semana. Foram observadas contagens elevadas em superfícies de bancadas e utensílios, e em todos os restaurantes havia alguma superfície de preparo com contagem superior ao limite máximo estipulado pela American Public Health Association. Medidas de controle devem ser implementadas nos restaurantes para contribuir no fornecimento de refeições seguras aos consumidores.
