绵阳市市售食品病原菌污染状况调查

Survey of contamination status of market foods with pathogenic bacteria in Mian-yang

目的了解病原菌在绵阳市市售食品中的污染状况,为进行食品风险评估和制定食品安全风险管理决策提供技术依据。方法按照《2010年四川省食源性疾病监测工作手册》提供的微生物检验标准操作程序对2010年8～12月采集的9大类15种食品共计249个样品按要求进行沙门菌、单增李斯特菌、金黄色葡萄球菌、副溶血弧菌、创伤弧菌、空肠弯曲菌、大肠杆菌O157:H7、阪崎肠杆菌8种致病菌的分离鉴定。结果 249份样品中共检出致病菌28株,总检出率为11.2%(28/249),其中沙门菌检出12株,检出率为5.0%(12/240),单增李斯特菌检出11株,检出率9.7%(11/114),金黄色葡萄球菌检出3株,检出率为3.0%(3/99),副溶血弧菌检出1株,检出率2.8%(1/36),创伤弧菌检出1株,检出率为2.8%(1/36),未检出空肠弯曲菌、大肠杆菌O157:H7、阪崎肠杆菌。结论绵阳市2010年食品受到一定程度的污染,存在发生食源性疾病的风险。生肉类、动物性水产品、沙拉是我市食品安全风险的高危食品;单增李斯特菌、沙门菌、金黄色葡萄球菌是引起食源性疾病的潜在高危致病菌。

Objictive To understand the contamination status of pathogenic bacteria in market foods in Mian-yang City,So as to provide the technical support of the food safety assessment.Methods according to the method from Sichuan Provincial Food-borne Pathogen Monitor Protocol-2010》,Salmonellae,Listeria monocytogenes,Staphylococcus aureus,Vibrio parahaemolyticus,Vibrio vulnificus,Campylobacter jejuni,Excherichia coli O157：H7,Enterobacter sakazakii from August to December in 2010 were isolated and identified.From 249 food samples of 15 kinds in categories.Results There 28 pathogenic bacteria（11.2% 28/249） were identified including 12 Salmonella（5.0% 12/240）,11 Listeria monocytogenes,（9.7%11/114）,3 Staphylococcus aureus（3.0% 3/99）,1 Vibrio parahaemolyticus（2.8% 1/36）,1 Vibrio vulnificus（2.8% 1/36）.Campylobacter jejuni,Escherichia coli O157：H7 and Enterobacter sakazakii were not detected.Conclusion Some foods were,to a certain extent contaminated in Mianyang in 2010 and effective measured be taken to improve the hygienic conditions of foods.
