常州市校园及其周边食品微生物污染情况分析

Analysis of Food Microbial Pollution in Changzhou Campus and Its Surrounding Areas

目的:了解江苏省常州市校园及其周边商店食品卫生状况。方法:2021—2023年每年选择1个城区和1个郊县,每个县(区)随机抽取小学各2所,中学各1所,中等职业学校各1所,大学共1所,每年监测9所学校。采集学校及其周边商店中学生食用频率较高的学生餐、含乳饮料、现制饮料、学生饮用奶、调味面制品和豆干,并进行卫生指示菌及常见食源性致病菌等指标的检测。结果:部分学生餐中检出蜡样芽胞杆菌,个别学生餐中检出金黄色葡萄球菌;调味面制品、豆干及现制饮料均未检出食源性致病菌,但部分现制饮料中菌落总数和大肠埃希氏菌计数超出检出限且存在超标情况。结论:校园食品生产者、加工者、经营者等均应采取防控措施尽可能降低致病菌含量,减少食源性疾病的发生概率。

Objective:To understand the food hygiene status of campus and its surrounding stores in Changzhou city,Jiangsu province.Method:From 2021 to 2023,one urban area and one suburban county were selected each year.In each county(district),two primary schools,one middle school,one secondary vocational school and one university were randomly selected,and nine schools were selected each year.Students’meals,milk drinks,freshly made drinks,milk,flavored flour products and dried beans,which were frequently consumed by students in schools and surrounding stores,were collected,and common foodborne pathogens were detected.Result:Bacillus cereus was detected in some students’meals,Staphylococcus aureus was detected in some students’meals.No food-borne pathogens were detected in flavoured flour products,dried beans and ready-made beverages,but the total number of bacterial colonies and Escherichia coli in some ready-made beverages exceeded the detection limit and exceeded the limit.Conclusion:The producers,processors and operators of campus food should take prevention and control measures to reduce the content of pathogenic bacteria as much as possible and reduce the probability of foodborne diseases.
