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.

摘要

收获后,将贝肉牡蛎分别储存在10℃、13℃和18℃的可控温度下以及环境空气温度(23至34℃)下,在12小时和30小时后对创伤弧菌进行采样。在13℃及以下,创伤弧菌在牡蛎中无法繁殖。在18℃下保存30小时以及在环境条件下保存12小时和30小时的牡蛎中,创伤弧菌的数量在统计学上显著高于收获时的牡蛎(P < 0.05)。这些数据表明,内源性创伤弧菌可在未冷藏的贝肉牡蛎中繁殖。
