ABSTRACT
O objetivo foi avaliar o padrão microbiológico de sushis e sashimis de salmão comercializados em restaurantes especializados situados na cidade de Pelotas, Rio Grande do Sul. Foram analisadas 20 amostras (10 de sushi e 10 de sashimi) submetidas à pesquisa de Salmonella, contagens de coliformes termotolerantes, Staphylococcus coagulase positiva e Vibrio parahaemolyticus. Observou-se que 70% das amostras estavam em desacordo com o padrão estabelecido pela legislação brasileira para estes produtos. Os resultados indicam a necessidade de maiores cuidados em relação à qualidade da matéria-prima e às medidas higiênicas e sanitárias durante o preparo e manipulação do produto, tendo em vista, ainda, o fato de que estes alimentos são consumidos sem cocção, o que aumenta o risco de contaminação.(AU)
This study aimed to evaluate the microbiological patterns of salmon sushi and sashimi sold in specialized restaurants located in the city of Pelotas, Rio Grande do Sul, Brazil. Twenty samples were analyzed (10 sushi and 10 sashimi) and submitted to Salmonella testing and counting of fecal coliforms, coagulase-positive Staphylococcus and Vibrio parahaemolyticus. One observed 70% of the samples were at odds with the standards established by the Brazilian law. The results indicate the need for more care about the quality of the raw material and for hygiene and sanitary measures when preparing and handling the product, also considering that these foods are consumed without cooking, which increases the risk of contamination.(AU)

The aim of this study was to trace the sources of Salmonella contamination during the pig slaughter flowchart. Ten lots of pigs sent for slaughter were followed (four animals per lot), and two weeks before slaughter they were selected based on the presence or absence of Salmonella in their farm stalls. Stool samples were collected after stunning, and from the surface swabs of the carcass in different parts of the flowchart. Samples were also collected immediately after the animals left the dehairing machine, after opening the abdominal cavity, before the carcass entered the cooling chamber, and from jowl samples. The water samples used in the scalding tank were collected before commencing the slaughter process and after the passage of the animals. For the comparison of band patterns, the isolates were analyzed by rep-PCR. The percentage of isolation was 35.3% after stunning, 17.6% immediately after the animals left the dehairing machine, 17.6% after evisceration, 23.5% before entering the cooling chamber and 5.8% from the jowls. The serotypes obtained were: Senftenberg, Idikan, Typhimurium, Heidelberg, Minnesota, Panama and Salmonella group O:4,5. By repPCR analysis, it was found that Salmonella strains that reached the slaughterhouse in carrier pigs may not be eliminated during processing, thereby making its isolation from the carcasses possible. It was also observed that the strains introduced by animals can infect others in different stages of the slaughter flowchart, thus resulting in cross-contamination.(AU)
