The consumption of fish, due to the pandemic situation experienced, had a large increase, which may be associated with the population's search for healthier foods with a greater nutritional value, considering the characteristics that fish has for having essential amino acids, minerals and a high value. protein. The increase in demand can end up affecting the quality of the product that will reach the consumer, and with that, causing several food-borne diseases due to bacterial contamination. The objective of this work was to microbiologically analyze fish fillets found in the market of the city of Pelotas-RS, in order to obtain results for the presence of Salmonella and Staphylococcus coagulase positive counts. The samples were obtained refrigerated in fishmongers in the city, being conditioned in ice until the moment of preparation for analysis, and the frozen samples were obtained in the commercial area of Pelotas, and kept frozen until the moment of analysis. The analyzes followed ISO 6579:2002 for Salmonella, and ISO 6888-1:2016 for coagulase-positive Staphylococcus, and expressed according to Normative Instruction IN 60, of December 23, 2019. The results showed that of the 41 samples analyzed, being 39 refrigerated and 2 frozen, of these, 16 samples presented counts for Staphylococcus coagulase positive, however, within the limits of the legislation. Regarding Salmonella, 03 samples showed the pathogen. These results show that it is important to follow the GMP's during the preparation processes and proper cooking of the product, in order to avoid food poisoning and cross-contamination through utensils or food.
