| Resumo: |
Oysters are filter feeders able to ingest particles in suspension that may carry pathogenic microorganisms. In this respect, the consumption of raw oysters can cause foodborne diseases in humans. The aim of the present study was to evaluate the microbiological quality of Crassostrea gigas oysters cultivated and commercialized in the coastal region of Florianópolis, SC, Brazil. The study comprised counts of coliforms at 35ºC and at 45ºC, Escherichia coli and coagulase-positive staphylococci, and detection of Salmonella sp, Vibrio cholerae and Vibrio parahaemolyticus. Ninety samples were analyzed, 45 of them collected at seafood commercial establishments and the other 45 were collected in the cultivation area. All analyses were performed according to methods of the American Public Health Association. Vibrio cholerae, V. parahaemolyticus and Salmonella sp. were not detected in any of the samples. Coagulase-positive staphylococci were observed in only one sample (80 CFU/g). The counts of coliforms at 35 and 45ºC indicated that samples obtained from both the cultivation area and place of sale were contaminated. E. coli was detected in 4 (9%) samples collected in the cultivation area and in 16 (35.5%) samples obtained from commercial establishments. These results indicate the need for monitoring the quality of raw oysters, including the implantation of programs for good mollusk manipulation and management practices.
