摘要
目的对东海县2乡镇同一天内发生由山夫登堡沙门菌引起的食物中毒事件开展溯源调查,为该类事件处置及预防提供参考。方法对2起食物中毒20例患者进行现场流行病学调查,采集可疑剩余食品、相关人员肛拭子、容器涂抹样等进行检测;对检出的9株沙门菌进行血清分型,用脉冲场凝胶电泳(PFGE)技术进行分子分型。结果2起食物中毒所食用的猪耳朵为某农贸市场同一摊位生产,9株沙门菌血清分型显示同为山夫登堡沙门菌,PFGE分型显示带型相似度100%。结论该2起食物中毒事件均为食品加工烹饪环节受山夫登堡沙门菌污染所引起,经溯源调查是1起食物中毒事件,与某农贸市场某摊位所销售的肉制品污染有关。
Objective To perform a tracing investigation of food poisoning events caused by Salmonella Senftenberg within one day in two townships of Donghai County,so as to provide insights into response to and prevention of food poisoning events.Methods A field epidemiological survey was performed among 20 cases during two food poisoning events.The suspected remaining food,anal swab samples and container coating samples were collected.The detected 9 Salmonella isolates were serotyped,and molecular typing was performed using pulsed-field gel electrophoresis(PFGE).Results The pig ears causing two food poisoning events were produced by the same stall in an agricultural trade market.Serotyping of 9 Salmonella isolates revealed Salmonella Senftenberg in all 9 isolates,and PFGE showed 100%similarity in detected bands.Conclusions These two food poisoning events were both caused by contamination with Salmonella Senftenberg during the food processing and cooking,and tracing investigations identified that these two events belonged to a food poisoning event,which was associated with the contamination of meat products sold by a stall in an agricultural trade market.
