【摘要】：目的核实2011年宁波市某中学食物中毒情况,查明病因,为学校食物中毒防控提供依据。方法通过与学校相关负责人座谈和现场访谈了解疫情及学校情况,对学生采取填写问卷的方式掌握其暴露与发病情况,采用病例对照研究的方法开展调查。结果本次食物中毒罹患率为9.37%,病例以发热、腹痛、腹泻等症状为主。不同年级、教学楼、性别及住宿与走读生之间罹患率差异均有统计学意义(P值均0.05)。28日午餐的肉皮烧萝卜(OR=4.48)、29日午餐的肉皮烧萝卜(OR=2.22)和晚餐的咸菜炒蛋(OR=2.38)是本次食物中毒的可能危险因素。结论此次事件系肠炎沙门菌污染食堂饭菜而导致的群体性食物中毒事件,可能为食物加工过程中交叉污染或伴加热不均导致,对食堂和宿舍用水进行消毒后,疫情得到有效控制。
