摘　　要：目的查明引起某庙会期间发生的一起食源性疾病暴发事件的原因,确认致病危害因素及其来源,为此类事件预防控制提供参考。方法开展现场流行病学调查,通过描述分析方法分析病例临床特征、流行病学特征及相关危害因素。开展病例对照研究确定可疑食物,通过脉冲场凝胶电泳(PFGE)法对致病因子进行相似性分析。结果根据病例定义共收集可疑病例32例,主要临床表现为腹痛(87.50%)、腹泻(78.13%)、发热(75.00%)、头晕恶心(71.88%)。病例对照研究结果显示水煮带壳花生是危险因素(OR=4.000,95%CI:1.409~11.354)。采集28份样品中有7份分离培养出沙门菌,血清型鉴定均为阿邦尼沙门菌,经PFGE图谱分析高度相似。结论本次事件是由阿邦尼沙门菌引起的食源性疾病暴发,可疑食物为水煮带壳花生,应加强非城区流动摊位散装食品的监管,同时加强食源性疾病监测管理工作。Objective To provide experience for the prevention and control of outbreaks,the cause of a foodborne disease outbreak during a temple fair was analyzed,the hazard factors and its source was confirmed.Methods Field epidemiological investigation and descriptive analysis method were carried out to analyze the clinical characteristics,epidemiological characteristics and related risk factors.Case-control study was conducted to identify suspicious foods,and pulsed field gel electrophoresis(PFGE)was used to evaluate strains homology.Results A total of 32 suspicious cases were collected according to the case definition.The main clinical manifestations were abdominal pain(87.50%),diarrhea(78.13%),fever(75.00%),dizziness and nausea(71.88%).It was showed that boiled peanuts with shells was the risk factor(OR=4.000,95%CI:1.409-11.354).There were 7 samples detected with Salmonella in 28 samples,all of which were identified by serotyping as Salmonella abony,with highly homologous by PFGE analysis.Conclusion This incident was an outbreak of foodborne diseases caused by Salmonella abony,and the suspected food was boiled peanuts with shells.The supervision of bulk food sold by mobile stalls in non-urban area should be strengthened,and the monitoring and management of foodborne diseases should be strengthened.
