目的了解一起聚餐引起食物中毒的原因、暴发范围及途径等相关情况,为采取有效的预防控制措施提供科学依据。方法制定统一的调查表,对2014年8月21日甘肃省渭源县会川镇参加一起聚餐后出现恶心、呕吐、腹痛和腹泻等消化道症状的93例病人和50名未发病者作为对照进行调查,并采集病人呕吐物和腹泻物、厨师的肛拭子进行致病菌检测,利用Logistic回归分析可疑食物。结果 93名中毒者中,男37例、女56例,性别比为0.660 7∶1;所有病人经过抗生素、补液和维持水电解质平衡治疗后,病情很快得到改善后痊愈;中毒病人餐后发病最短时间1.10 h,最长12.00 h,中位数潜伏期为4.20 h,其中4 h~最多(20例)、占21.51%;中毒病人中40岁~组最多(26例)、占27.96%,其次是50岁~组(19例)、占20.43%,70岁~组最少(7例)、占7.53%;对单因素Logistic回归分析差异有统计学意义的食物再进行多因素Logistic回归分析,只有蒜泥豆角差异有统计学意义(P<0.05)。结论本次中毒事件是由蒜泥豆角引起的细菌性食物中毒。 Objective To understand the causes of the food poisoning caused by the dinner, the scope and route of the outbreak and other related situations, so as to provide a scientific basis for effective prevention and control measures. Methods A unified questionnaire was established. 93 patients with nausea, vomiting, abdominal pain and diarrhea and other gastrointestinal symptoms after dinner party in Huichuan, Weiyuan County, Gansu Province on August 21, 2014 were enrolled as control Conducted investigations and collected vomitus and diarrhea patients, chef’s anal swab pathogen detection, the use of Logistic regression analysis of suspicious foods. Results Among the 93 poisoned patients, 37 were male and 56 were female, with a sex ratio of 0.660 7:1. All patients were cured quickly after antibiotic, rehydration and water-electrolyte balance were maintained. Patients with poisoning developed postprandial The shortest time was 1.10 h, the maximum was 12.00 h, and the median incubation period was 4.20 h, of which 4 h ~ the most (20 cases), accounting for 21.51%; the most poisoning patients were 40 years old ~ group (26 cases), accounting for 27.96% Was 50 years old ~ group (19 cases), accounting for 20.43%, 70 years ~ group minimum (7 cases), accounting for 7.53%; univariate Logistic regression analysis of statistically significant food further multivariate Logistic regression analysis, only The difference of garlic bean was statistically significant (P <0.05). Conclusion The poisoning incident is caused by Bacon bean poisoning.
