Effect of time and temperature on multiplication of Vibrio vulnificus in postharvest Gulf Coast shellstock oysters

Abstract
After harvest, shellstock oysters stored under controlled temperatures of 10, 13, and 18 degrees C and at ambient outside air temperature (23 to 34 degrees C) were sampled after 12 and 30 h for Vibrio vulnificus. At 13 degrees C and below, V. vulnificus failed to multiply in the oysters. In oysters held at 18 degrees C for 30 h and under ambient conditions for 12 and 30 h, V. vulnificus numbers were statistically greater (P < 0.05) than those in oysters at harvest. These data indicate that endogenous V. vulnificus can multiply in unchilled shellstock oysters.
