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。
Objective To understand the food-borne pathogens in Songyuan City. Methods A total of 12 types of foods from 5 counties and cities (districts) in 2016 were collected. According to the manual of foodborne pathogens surveillance in Jilin Province in 2016, Salmonella, Staphylococcus aureus and Vibrio parahaemolyticus were detected, Listeria monocytogenes, Enterobacter sakazakii, Bacillus cereus and diarrheogenic Escherichia coli. Results Twenty-two pathogenic bacteria were detected in 205 samples of 12 kinds of food samples collected, with a total detection rate of 10.7%. Enterobacter sakazakii had the highest detection rate (30%) among the eight pathogens, followed by Bacillus cereus (11.1%). Among the 12 types of food, infant cereal supplements have the highest contamination rate (45%), followed by student meals (26.7%). Animal freshwater products, instant non-fermented soybean products and fresh fruit and vegetable juices and other foods are subject to varying degrees of foodborne pathogens contamination. Conclusion There are different levels of food-borne pathogenic bacteria in food in Songyuan City, and there is a risk of contamination of pathogenic bacteria in infant food.
