Abstract in Portuguese
Introdução. Doenças de origem alimentar são causadas por organismos que entram no corpo humano através da ingestão de alimentos contaminados. O pescado pode veicular uma variedade de microrganismos patogênicos para o homem, aumentando a preocupação com a qualidade sanitária de peixes e suas preparações devido a globalização do consumo de peixe cru. Objetivo. Avaliar a qualidade microbiológica de sushis e sashimis servidos em restaurantes de auto-serviço na cidade de São Paulo, e estabelecer a relação entre os resultados e a forma com que estes pratos são apresentados aos consumidores. Métodos. Vinte amostras de diferentes estabelecimentos foram submetidas a análises microbiológicas, de acordo com a American Public Health Association (APHA) para coliformes termotolerantes, Salmonella, Staphylococcus aureus, Bacillus cereus, Vibrio parahaemolyticus e espécies de Aeromonas. Resultados. Das amostras estudadas, 50% apresentaram contagem de coliformes termotolerantes acima dos limites estabelecidos pela legislação brasileira RDC 12/2001. Escherichia coli foi observada em 45% das amostras, 15% das amostras tinham contagem de S. aureus acima do limite e, em 35%, espécies potencialmente patogênicas de Vibrio foram isoladas. Aeromonas spp e Bacillus cereus foram obtidos de 75% e 15% das amostras respectivamente e Salmonella spp não foi isolada nas amostras estudadas. Discussão. Levando em conta o potencial patogênico dos microrganismos isolados das amostras, considera-se que o consumo de sushi e sashimi pode representar um fator de risco para a saúde pública.

Abstract in English
Introduction. Foodborne diseases are those caused by organisms entering the human body through the ingestion of contaminated food. Fish can carry a variety of pathogenic microorganisms increasing the concern with the sanitary quality of fish and its preparations due to the globalization of raw fish consumption. Objective. To evaluate microbiologic quality of sushi and sashimi, served in self service restaurants in the city of São Paulo and to establish the relationship between the results and the form in which the dish is presented to consumers. Methods. Twenty samples, from different establishments were subjected to microbiological analysis according to the American Public Health Association (APHA) for thermo-tolerant coliform bacteria, Salmonella, Staphylococcus aureus, Bacillus cereus, Vibrio parahaemolyticus, and Aeromonas species. Results. From the studied food samples, 50% presented counts of thermo-tolerant coliform above the limits established by the Brazilian Legislation RDC 12/2001. Escherichia coli was observed in 45% of the samples, 15% of the samples had S. aureus counts above the limits and in 35% potentially pathogenic species of Vibrio were recovered. Aeromonas and Bacillus cereus were obtained from 75% and 15% of the samples respectively and Salmonella was not recovered from the samples studied. Discussion. Taking into account the pathogenic potential of the microorganisms isolated from the samples, one can consider that the consumption of sushi and sashimi dishes can pose a public health risk.
