2008年江苏省食源性致病菌监测分析

Jiangsu Province food-borne pathogens surveillance in 2008

目的:了解江苏省食品中7种食源性致病菌的污染情况和分布状况,为预防和控制食源性疾病提供科学依据。方法:依据《2008年度国家食源性疾病监测网工作手册》检测技术要求,对757份食品样品进行沙门菌、单增李斯特菌、副溶血性弧菌、金黄色葡萄球菌、弯曲菌、大肠杆菌O157、阪崎肠杆菌的分离鉴定。结果:757份食品样品中共检出118株致病菌,总检出率为15.59%(118/757)。7种食源性致病菌中,副溶血性弧菌检出率最高(13.46%),其次为金黄色葡萄球菌(6.95%)、单增李斯特菌(6.56%)和沙门菌(6.06%),未检出弯曲菌和大肠杆菌O157。8大类食品中,生肉和动物性水产品污染率最高,分别为32.61%和29.49%。结论:江苏省主要消费食品中存在食源性致病菌污染,生肉和动物性水产品是污染的高危食品,生肉主要被单增李斯特菌和沙门菌污染,动物性水产品主要被副溶血性弧菌污染。

Objective：To know the contamination and distribution of food-borne pathogens in 8 kinds of food in Jiangsu Province for providing the basis for prevention and control of food-borne diseases.Methods：According to the standard operation procedure of the national surveillance on food-borne pathogens,757 food samples were detected to see if Salmonella,Listeria monocytogens,Vibrio parahaemolyticus,Staphylococcus aureus,Campylobacter jejuni,Escherichia coli O157 and Enterobacter sakazakii were positive.Results：118 bacteria strains were separated from 757 food samples,the overall positive rate was 15.59%（118/757）.The positive rate of Vibrio parahaemolyticus was the highest（13.46%）,then Staphylococcus aureus（6.95%）,Listeria monocytogens（6.56%） and Salmonella（6.06%）,Campylobacter jejuni and Escherichia coli O157 were not found.In the 8 kinds of food samples,raw meat and aquatic products were highly contaminated,positive rate 32.61% and 29.49% respectively.Conclusion：There was food contamination by pathogens in Jiangsu province.Raw meat were mainly polluted by Listeria monocytogens and Salmonella,aquatic products by Vibrio parahaemolyticus,both of them were high-risk food.
