    摘要:

    目的 了解生食动物性水产品中副溶血性弧菌和创伤弧菌污染状况。方法 采用随机抽样方法,在我国13个地区的餐饮店、零售店和批发市场采集生食动物性水产品,共计2 980份,对样品进行副溶血性弧菌和创伤弧菌检测。结果 生食动物性水产品中副溶血性弧菌检出率为14.7%(437/2 980),污染水平>100 MPN/g的样品比例为2.9%(83/2 909);创伤弧菌检出率为3.5%(104/2 980)。采样于批发市场的样品中副溶血性弧菌检出率、污染水平>100 MPN/g的样品比例和创伤弧菌检出率均高于餐饮店和零售店。第三季度副溶血性弧菌检出率、污染水平>100 MPN/g的样品比例和创伤弧菌检出率最高。造成污染的主要原因包括原产地污染,储存不当及加工过程交叉污染。结论 生食动物性水产品中存在副溶血性弧菌和创伤弧菌的污染,其健康风险应引起关注,本次污染状况分析可为标准制修订提供理论依据。

    Abstract:

    Objective To understand Vibrio parahaemolyticus and Vibrio vulnificus contamination in raw ready-to-eat (RTE) aquatic products. Methods Using the principle of random sampling, 2 980 samples of raw RTE aquatic products were collected from restaurants, retail stores and wholesale markets in 13 regions of China, to monitor the contamination status of Vibrio parahaemolyticus and Vibrio vulnificus. Results The detection rate of Vibrio parahaemolyticus was 14.7%(437/2 980), the proportion of samples with >100 MPN/g was 2.9%(83/2 909), and the detection rate of Vibrio vulnificus was 3.5%(104/2 980). The detection rate of Vibrio parahaemolyticus, the proportion of samples >100 MPN/g and the detection rate of Vibrio vulnificus in samples from wholesale markets were higher than those from restaurants and retail stores. The detection rate of Vibrio parahaemolyticus, the proportion of samples with >100 MPN/g, and the detection rate of Vibrio vulnificus were the highest in the third quarter. The main causes of contamination included pollution in source areas, improper storage conditions and cross-contamination during processing. Conclusion There were Vibrio parahaemolyticus and Vibrio vulnificus contamination in raw RTE aquatic products, and its risk to health deserved enough attentions.
