目的了解北京市大兴区市售食品中食源性致病菌污染状况。方法 2006-2008年,采集大兴辖区内的10类食品,对沙门菌、大肠埃希菌O157:H7、金黄色葡萄球菌、单核细胞增生李斯特菌、空肠弯曲菌和副溶血性弧菌等6种食源性致病菌进行监测分析。结果食源性致病菌检出率为11.96%(67/560)。金黄色葡萄球菌的检出率最高(6.79%,38/560),其次为单核细胞增生李斯特菌(3.57%,20/560)和沙门菌(1.61%,9/560)。560份食品中均未检出大肠埃希菌O157:H7、空肠弯曲菌和副溶血性弧菌。生牛奶中金黄色葡萄球菌检出率最高(30.67%,23/75),其次为生肉(15.29%,39/255)、鲜冻水产品(5.45%,3/55)和熟肉制品(2.67%,2/75)。结论大兴区市售食品中食源性致病菌污染较为普遍,生牛奶、生肉类、鲜冻水产品及散装熟肉制品可能是导致食源性疾病的高危食品。
Objective To understand the status of food-borne pathogen contamination in commercial food in Daxing District of Beijing. Methods From 2006 to 2008, 10 kinds of foodstuffs in Daxing area were collected to detect Salmonella, Escherichia coli O157: H7, Staphylococcus aureus, Listeria monocytogenes, Campylobacter jejuni and Vibrio parahaemolyticus Six kinds of foodborne pathogens were monitored and analyzed. Results The detection rate of foodborne pathogens was 11.96% (67/560). The detection rate of Staphylococcus aureus was the highest (6.79%, 38/560), followed by Listeria monocytogenes (3.57%, 20/560) and Salmonella (1.61%, 9/560). Escherichia coli O157: H7, Campylobacter jejuni and Vibrio parahaemolyticus were not detected in 560 food samples. The detection rate of Staphylococcus aureus in raw milk was the highest (30.67%, 23/75), followed by raw meat (15.29%, 39/255), fresh frozen seafood (5.45%, 3/55) and cooked meat products %, 2/75). Conclusion The food-borne pathogens in Daxing District are more and more commonly contaminated. Raw milk, raw meat, fresh-frozen aquatic products and bulk cooked meat products may be the high-risk foods leading to foodborne diseases.
