18 个省辖市的实际情况?覆盖城市和农村包括城乡结合部?分配采样计划?采集河南省学生餐

862 份?并进行金 黄色葡萄球菌、蜡样芽孢杆菌、单核细胞增生李斯特菌、沙门菌和致泻大肠埃希菌等致病菌的检测? 结果 学生餐样品食 源性致病菌的整体检出率为 8.

58%?其中金黄色葡萄球菌和蜡样芽胞杆菌检出率分别为 3.13%和4.40%?致泻大肠埃希菌、 单核细胞增生李斯特菌和沙门菌检出率较低?分别为 0.70%?0.23%和0.12%? 乳与乳制品、豆制品、米面制品以及盒饭中 食源性致病菌污染率相对较高?分别为 17.86%?12.50%?9.79%和8.79%? 农村和城市学生餐中食源性致病菌检出率分别 为14.29%和7.48%?差异有统计学意义(χ2 = 6.920?P= 0.009)? 结论 河南省学生餐存在致病菌污染隐患?应加强对高污 染率食品类别学生餐的卫生监测和监管? 【关键词】 沙门菌食物中毒?葡萄球菌食物中毒?食品污染?公共卫生 【中图分类号】 R

862 food samples were collected and detected based on Food Safety Risk Monitoring Plan in Henan in 2014. The test items conclude Bacillus cereus Staphylococcus aureus Listeria monocytogenes Escherichia coli and Salmonella. Results Among the

862 samples of student meals the overall detection rate of main pathogenic bacteria was 8.58%. The detection rate of Staphylococcus aureus and Bacillus cereus were 3.13% and 4.40% and lower detection rate was 0.70% 0.23% and 0.12% in Escherichia coli Listeria monocytogenes and Salmonella. The detection rate of milk and dairy products bean products rice food and box lunches was 17.86% 12.50% 9.79% and 8.79% respectively. There were significant differences of food~borne pathogenic bacteria detection between students in city 14.29 % and those in countryside 7.48 % χ2 = 6.920 P= 0.009 . Conclusion There are hidden dangers of foodborne pathogenic bacteria contamination in student meals provided by school in Henan Province. In order to avoid the break of food poisoning in school food safety monitoring and supervision should be strengthened on high contamination rate of student meals. 【Key words】 Salmonella food poisoning Staphylococcal food poisoning Food contamination Public health 【基金项目】 河南省科技攻关项目(162102310310)? 【作者简介】 吴玲玲(1990- )?女?河南郑州人?硕士?技师?主要从 事食品安全风险监测和微生物检验工作? 【通讯作者】 张丁?E~mail:zhangd222@ hncdc.com?
