目的了解广西学校学生餐食源性致病菌污染状况,为食源性疾病的预防和控制提供依据。方法 2014年从广西7个市和19个县的幼儿园和大中小学采集统一供应的早餐和午餐样品520份,按照国家标准进行蜡样芽胞杆菌、金黄色葡萄菌、单核细胞增生李斯特菌、致泻大肠埃希菌、沙门菌检验。结果学生餐样品中蜡样芽胞杆菌检出率为15.54%,金黄色葡萄球菌检出率为1.92%,单核细胞增生李斯特菌检出率为0.19%,致泻大肠埃希菌检出率为0.76%,未检出沙门菌;市级和县级学生餐食品的致病菌检出率分别为13.51%和14.29%;早餐和午餐的检出率分别为10.12%和15.63%;第一季度无致病菌,第二、三季度的致病菌检出率(15.55%和18.55%)均高于第四季度(8.63%)。结论广西学生餐存在不同程度食源性致病菌污染,应在重点季度加强学生餐食品安全监管,防止学校食物中毒事件的发生。
Objective To understand the status of food-borne pathogenic bacteria in school students in Guangxi and provide the basis for the prevention and control of food-borne diseases. Methods A total of 520 breakfast and lunch samples were collected from kindergartens, middle schools and primary schools in 7 cities of Guangxi and 19 counties in 2014. Bacillus cereus, Staphylococcus aureus and Listeria monocytogenes were collected according to the national standard. , Diarrhea Escherichia coli, Salmonella test. Results The results showed that the detection rate of Bacillus cereus was 15.54%, the detection rate of Staphylococcus aureus was 1.92%, the detection rate of Listeria monocytogenes was 0.19%, the detection rate of diarrhea Escherichia coli And 0.76% respectively. Salmonella was not detected. The prevalence of pathogenic bacteria in food products was 13.51% and 14.29% respectively for city and county students. The detection rates of breakfast and lunch were 10.12% and 15.63% respectively. The first In the second and third quarters, the detection rates of pathogens (15.55% and 18.55%) were higher than those in the fourth quarter (8.63%). Conclusion There is some degree of contamination of food-borne pathogenic bacteria in student meal in Guangxi. It is necessary to strengthen the safety supervision of food and meal of students in key quarters and prevent the occurrence of school food poisoning incidents.
