A family outbreak of Escherichia coli O157 infection was microbiologically associated with consumption of dry-fermented salami made with pork meat only and produced in a local plant. E. coli O157 strains isolated from a wife and husband, both hospitalized with bloody diarrhoea, and from the salami carried vt1, vt2 and eae genes and shared the same PFGE pattern. The food vehicle implicated in this outbreak is unusual because of both the animal species from which it originates and the fermentation and drying steps of the manufacturing process. This could be the first report of an outbreak associated with a product containing pork meat only. Even though sources of contamination other than pork meat could not be excluded, pork products should not be neglected in E. coli O157 outbreak investigations.
一起大肠杆菌O157感染的家庭聚集性疫情在微生物学上与食用仅由猪肉制成且在当地工厂生产的干发酵意大利腊肠有关。从因血性腹泻住院的一对夫妻以及腊肠中分离出的大肠杆菌O157菌株携带vt1、vt2和eae基因，并具有相同的脉冲场凝胶电泳（PFGE）图谱。此次疫情涉及的食物载体不同寻常，这是由于其来源的动物种类以及制造过程中的发酵和干燥步骤。这可能是首例与仅含猪肉产品相关的疫情报告。尽管不能排除猪肉以外的其他污染来源，但在大肠杆菌O157疫情调查中，猪肉产品不应被忽视。
