摘要：From this study information doncerning the source and magnitude of fecal contamination of oysters ( Crassostrea virginica ) associateti with their cultivation, processing and marketing was obtained. Dunng a 12 month survey, 23 samples (of 20 oysters per sample) as well water samples from the Gulf of Mexico, were collected at 4 different growing areas. During the same period, 49 samples of the same species of oyster were collected from sea food markets, of these, 17 were unshucked oyster iiamples (of 20 oysters per sample), and 32 were shucked oyster samples (of 1 bottle with 15 shucked oysters per sample). The counts of total coliforms (TC) and fecal coliforms (FC) in the waters from the majority of growing areas were greater than the recommended standards for approved oyster growing areas ( -1 and -1 and 2.7 X. 10s FC 100 ml -1 . Salmonella was not detected in these oyster samples, although two potential pathogenic species ( Escherichia coli and Plesiomonq shigelloides ) among enteric bacteria were present. The results of this study showed that raw oyster consumption represents a potentia1 risk to human health due to the unsanitary manner in which such shellfish are grown, processed and marketed.

The highest bacteria1 counts were found in oyster samples from the sea food market, presenting a geometric mean of 9.5 X 101 TC 100 ml-1 and 2.7 X. 10s FC 100 ml-1. Salmonella was not detected in these oyster samples, althoughtwo potential pathogenic species (Escherichia coli and Plesiomonq shigelloides) among enteric bacteria were present.The results of this study showed that raw oyster consumption represents a potentia1 risk to human health due to the unsanitary manner in which such shellfish are grown, processed and marketed.
