title: 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.
