目的 了解浙江省近年食物中毒事件的流行病学特征和趋势变化,提出当前防控重点。 方法 对2006-2011年浙江省突发公共卫生事件监测系统报告的食物中毒事件进行描述流行病学分析,并与1992-2004年浙江省及同期全国平均水平进行对比。 结果 2006-2011年浙江省共报告食物中毒突发公共卫生事件相关信息106起。以微生物类事件为主(占67.92%),其中又以副溶血弧菌为最常见致病菌(占33.33%)。误食河豚鱼、毒蘑菇、亚硝酸盐的病死率明显高于其他类型的食物中毒。5-10月为食物中毒高发月份(占71.70%),微生物类事件夏秋季高峰更为明显。学校、厂矿企业是食物中毒的常见发生场所(分别占54.72%和14.15%),集体食堂、饮食服务单位是常见责任单位(分别占48.11%和17.92%)。 结论 近年浙江省报告的食物中毒事件发生规模及严重程度均呈现明显下降,当前防控重点场所为集体食堂、饮食服务单位,重点类型为副溶血弧菌等常见微生物污染事件。
Objective To understand the epidemiological characteristics and trend of food poisoning in Zhejiang province in recent years, and suggest the prevention and control priorities. Methods Descriptive epidemiological analysis was conducted on the incidence data of food poisoning reported through the public health emergency surveillance system in Zhejiang from 2006 to 2011, and comparison was made with the national data during the same period and the data in Zhejiang from 1992 to 2004. Results A total of 106 food poisoning events were reported in Zhejiang from 2006 to 2011. The majority was caused by microorganism contamination (67.92%), in which Vibrio parahaemolyticus was the most common pathogen (33.33%). The case fatality rates of puffer fish, poisonous mushroom and nitrite poisonings were much higher than those of other food poisonings. Most food poisoning occurred during May to October (71.70%), and the incidence of food poisoning caused by microorganism peaked in summer and autumn. Schools and enterprises were the major places where the food poisoning was prone to occurred (54.72% and 14.15% respectively). Food services, including canteens and restaurants, were responsible for the most poisoning events (48.11% and 17.92%, respectively). Conclusion The incidence of food poisoning declined in Zhejiang in recent years, and the severity was mild than before. Foods services are the key places for food poisoning prevention and control, and Vibrio parahaemolyticus is the major pathogen to which more attention should be paid in food poisoning prevention and control.
