Microbiological quality of the fish saw (Scomberomorus brasiliensis) and the ice used for its conservation

Abstract

This study aimed at evaluating the microbiological quality of the saw fish (S. brasiliensis) landed in the city of Raposa (MA) and the ice used in its conservation. Samples of ice and saw fish were subjected to analysis to determine the Most Probable Number (MPN) of coliforms, thermo-tolerants and Escherichia coli. Fish samples were also tested for Staphylococcus coagulase positive, Salmonellaspp. and Aeromonas spp. Fishermen were given a questionnaire with 20 questions concerning the handling of the fish. The ice samples showed unsatisfactory microbiological quality. The saw fish was contaminated with A. hydrophila, which means it could convey this agent to be consumed by the population.
