目的了解山东省市售水产品中食源性致病菌的污染状况,为相关部门有针对性地开展预防控制及标准制定提供科学依据。方法对2015-2016年山东省监测的1 090份市售水产品样品中的副溶血性弧菌、霍乱弧菌、沙门菌、单核细胞增生李斯特菌等4种常见食源性致病菌的污染现状进行分析。结果 1 090份水产品中,4种食源性致病菌检出率为32.29%(352/1 090)。其中,淡水产品的检出率高于海水产品(分别为35.95%和28.60%)。水产品中副溶血性弧菌检出率最高,为27.06%(295/10 90),其次为霍乱弧菌5.24%(30/572)和沙门菌3.49%(38/1 090),单增李斯特菌检出率最低,为1.74%(19/1 090)。淡水甲壳类、淡水螺类是食源性致病菌检出率较高的水产品种类,检出率分别为44.72%(55/123)、37.74%(20/53)。结论山东省市售水产品中污染的食源性致病菌主要以副溶血性弧菌为主,建议相关部门进一步加强水产品市场监管及风险监测工作。
Objective To understand the status of food-borne pathogenic bacteria in commercial aquatic products in Shandong Province and provide a scientific basis for relevant departments to carry out targeted prevention and control and standard-setting. Methods Four common food-borne pathogens, Vibrio parahaemolyticus, Vibrio cholerae, Salmonella, Listeria monocytogenes and so on, were collected from 1 090 samples of aquatic products tested in Shandong Province during 2015-2016. The status of pollution analysis. Results Among 1 090 aquatic products, the detection rate of 4 foodborne pathogens was 32.29% (352/1 090). Among them, the detection rate of freshwater products is higher than the seawater products (35.95% and 28.60% respectively). The highest detection rate of Vibrio parahaemolyticus in aquatic products was 27.06% (295/1090), followed by V. cholerae 5.24% (30/572) and Salmonella 3.49% (38/1 090) The lowest detection rate was 1.74% (19/1 090). Freshwater crustaceans and freshwater snails were the highest detection rate of foodborne pathogens. The detection rates were 44.72% (55/123) and 37.74% (20/53), respectively. Conclusion The main food-borne pathogenic bacteria contaminated by aquatic products in Shandong Province are mainly Vibrio parahaemolyticus, and the relevant departments are suggested to further strengthen the supervision and risk monitoring on the aquatic products market.
