Fifty-one interstate shipments of shellstock oysters were sampled at processing plants and examined bacteriologically for Vibrio vulnificus , fecal coliforms, Escherichia coli , and standard plate count. The occurrence of V. vulnificus in the oysters was seasonal with low numbers during the winter and levels frequently exceeding 110,000/g during the summer. The numbers of V. vulnificus correlated (p < 0.01) with fecal coliform levels in the oysters and with water temperatures in the harvest areas. Normal commercial processing did not significantly (p > 0.05) reduce the levels of V. vulnificus or indicator bacteria in the oyster meats. However, storage of the processed meats in containers packed on ice usually produced a one-log and two-log unit reduction in numbers of V. vulnificus after 3 and 7 d, respectively. |
