Risk monitoring of foodborne pathogens in food of Songyuan city in 2016

目的了解松原市市售食品的食源性致病菌污染状况。方法采集2016年全市5个县、市(区)的12类食品,依据吉林省2016年食源性致病菌监测工作手册,检测其中的沙门氏菌、金黄色葡萄球菌、副溶血性弧菌、单增李斯特氏菌、阪崎肠杆菌、蜡样芽孢杆菌和致泻性大肠杆菌。结果在采集的12类,共205份食品样品中,共检出致病菌22株,总检出率为10.7%。在8种致病菌中,阪崎肠杆菌的检出率最高(30%),其次是蜡样芽孢杆菌(11.1%)。在12类食品中,婴幼儿谷类辅助食品的污染率最高(45%),其次为学生餐(26.7%)。动物性淡水产品、即食非发酵豆制品和鲜榨果蔬汁等食品均存在不同程度的食源性致病菌污染。结论松原市食品中存在不同程度的食源性致病菌污染,婴幼儿食品存在受致病菌污染的风险。
