Microbiological characteristics of sushi acquired in establishments that sell Japanese food / Características microbiológicas de sushis adquiridos em estabelecimentos que comercializam comida japonesa

Food quality control refers to all and any action aimed at improving good practice in hygiene procedures and food handling. Therefore, there is a continuous need to obtain data, study and monitor the production and marketing in food industry thus producing a safe food, free from any contamination that may cause damage to the consumer´s health. So this study evaluated the microbiological quality of sushi bought in two types of establishments: 15 restaurants specialized in Japanese food and 15 non-specialized restaurants from the Ribeirão Preto - SP region. The populations of heterotrophic mesophiles and psychrotrophic microorganisms ranged from 3,9 x 102 to 1,7 x 107CFU.g-1 and 7,5 x 102 to 1,4 x 109CFU.g-1, respectively. All samples presented Staphylococcus spp. with populations ranging from 2,0 x 102 to 3,8 x 105CFU.g-1, where 23,3% were classified as positive coagulase Staphylococcus and 13.3% had population values above the established limit. Thermotolerant coliforms were found in 60,0% of the samples and 33,3% of them were above the established thermotolerant coliform limit. The presence of Staphylococcus aureus and Escherichia coli were identified in 16,7% and 30,0% of the samples, respectively. Salmonella sp. and Vibrio parahaemolyticus were not isolated in this research. There was no difference in the microbiological quality of sushi offered between the two types of establishments. According to the results it is concluded that sushi is a potential foodborne disease food and the non standard samples reflect the need to properly train the food handlers.(AU)

Com o crescimento do consumo da comida japonesa no Brasil surge a preocupação com doenças de origem alimentar relacionadas à ingestão do pescado cru e erros de manipulação desse tipo de alimentos. Diante dessa realidade, esse trabalho avaliou a qualidade microbiológica de sushis adquiridos em dois tipo de estabelecimentos: 15 restaurantes especializados em comida japonesa e 15 restaurantes não especializados da região de Ribeirão Preto SP. Quantificou-se microrganismos mesófilos, psicrotróficos, coliformes termotolerantes, Staphylococcus spp. e S. aureus, Escherichia coli, presença da Salmonella sp. e do Vibrio parahaemolyticus . As populações de microrganismos heterotróficos mesófilos e psicrotróficos variaram de 102a 107 UFC.g-1 e 102 a 109 UFC.g-1, respectivamente. Todas as amostras analisadas apresentaram Staphylococcus spp. com populações variando de 102a 105 UFC.g-1, sendo que 23,3% foram caracterizados como Staphylococcus coagulase positivo e 13,3% apresentaram valores de populações acima do limite estabelecido pela legislação vigente para pescado cru. Foram encontrados coliformes termotolerantes em 60,0% das amostras e 33,3% destas estavam acima do limite estabelecido. As presenças de Staphylococcus aureus e Escherichia coli foram identificadas em 16,7% e 30,0% das amostras, respectivamente. Salmonella spp. e Vibrio parahaemolyticus não foram isoladas nesse trabalho. Não houve diferença na qualidade microbiológica de sushis oferecidos entre os dois tipos de estabelecimentos. De acordo com os resultados conclui-se que o sushi é um alimento com potencial de veiculação de doenças de origem alimentar e as amostras fora do padrão refletem a necessidade de treinar adequadamente os manipuladores de alimento.(AU)
