An investigation was conducted to determine the vehicle of infection of an outbreak of food poisoning in a large metropolitan building early in 1988. A questionnaire was distributed to 700 people who had eaten in the building during the week of the outbreak, and attack rates for specific food were calculated. Food and stool samples, environmental samples, and eggs and environmental swabs from the egg suppliers were examined microbiologically. Altogether 474 questionnaires were returned, 120 people reporting gastrointestinal illness. The illness was significantly associated with foods containing mayonnaise. Salmonella typhimurium definitive type 49 was isolated from 76 of the 84 stool samples containing salmonella and from five of the eight samples taken from the chicken house of the main egg supplier. Mayonnaise was probably the vehicle of infection, which was caused by S typhimurium definitive type 49.
1988年初，针对某大型都市建筑内一起食物中毒暴发事件，开展了一项调查以确定感染源。向在暴发周内在该建筑内就餐的700人发放了调查问卷，并计算了特定食物的发病率。对食物和粪便样本、环境样本以及鸡蛋供应商的鸡蛋和环境拭子进行了微生物学检测。共收回474份问卷，120人报告患有胃肠道疾病。该疾病与含有蛋黄酱的食物显著相关。从84份含沙门氏菌的粪便样本中的76份以及从主要鸡蛋供应商鸡舍采集的8份样本中的5份中分离出鼠伤寒沙门氏菌49型。蛋黄酱可能是由鼠伤寒沙门氏菌49型引起的感染源。
