江苏省2008-2009年肉类和水产品食源性致病菌监测

Food-borne pathogens in meat and aquatic products in Jiangsu province,2008-2009

目的了解江苏省肉类和水产品中食源性致病菌的污染状况。方法按照GB/T 4789《中华人民共和国国家标准食品卫生微生物学检验》方法对采自江苏省13个市的肉类和水产品共计990份进行沙门氏菌、单增李斯特菌、大肠埃希菌O157、弯曲菌和副溶血性弧菌检测。结果 990份肉类和水产品中共检出致病菌161株,总检出率为16.26%,生肉类、熟肉类食品、鲜冻水产品、生食水产品检出率分别为26.32%、7.37%、17.78%、14.78%;不同地区样品中,泰州市食源性致病菌总检出率最高,为37.97%,其次为南京市和扬州市;采自农贸批发市场、超市和商店、饭店和食堂的样品中食源性致病菌检出率分别为22.99%、15.37%、6.76%。结论江苏省肉类和水产品中食源性致病菌污染比较严重,熟肉制品和生食水产品直接入口,可能导致较高的食源性疾病风险。

Objective To know the contamination situation of food-borne pathogens in meat and aquatic products in Jiangsu province.Methods According to GB/T 4789 examination method,990 meat and aquatic products from 13 cities in Jiangsu province were detected for Salmonella,Listeria monocytogens,Vibrio parahaemolyticus,Campylobacter jejuni,and Escherichia coli O157.Results Among the samples,161 bacteria strains were isolated with an overall positive rate of 16.26%.The detection rate of the pathogens for raw meat,cooked meat,frozen aquatic food,and raw aquatic products were 26.32%,7.37%,17.78%,and 14.78%,respectively.Food products from Taizhou city had the highest positive rate of food-born pathogens,followed by Nanjing and Yangzhou city.Positive rate of foods from wholesale markets was 22.92% and that of from supermarkets and stores was 15.37%,and 6.76% from restaurants.Conclusion There existed food-borne pathogen contamination in meat and aquatic products in Jiangsu province.The intake of cooked meat and raw aquatic food without heating is more likey to cause food-borne diseases.
