Fourteen cases of Escherichia coli O157 infection were reported to the consultant in communicable disease control in Sunderland Health Authority in August 1995. E. coli O157 phage type 2, Vero cytotoxin 2 was isolated from the faeces of ten cases. Nine of the isolates were indistinguishable by Vero cytotoxin subtyping and analysis of chromosomal DNA. Two cases with haemolytic uraemic syndrome were confirmed serologically and two cases remained unconfirmed. A case control study showed infection with E. coli O157 to be associated with having eaten precooked meats from a single shop. Environmental investigations at the shop showed that cooked meats were stored close to raw beef, raw meats were left on preparation surfaces, and the same staff served both raw and cooked meats. This outbreak draws attention to standards of food preparation and handling in outbreaks of E. coli O157, the issue of cross contamination, and the need to improve local surveillance of haemolytic uraemic syndrome.
1995年8月，桑德兰卫生局传染病控制顾问收到了14例大肠杆菌O157感染的报告。从10例患者的粪便中分离出了大肠杆菌O157噬菌体2型、维罗毒素2。通过维罗毒素亚型分析和染色体DNA分析，9株分离株无法区分。2例溶血性尿毒综合征病例经血清学确诊，2例仍未确诊。一项病例对照研究表明，感染大肠杆菌O157与食用来自同一家商店的预煮肉类有关。对该商店的环境调查显示，熟肉与生牛肉存放在一起，生肉放在操作台上，且由同一批员工处理生肉和熟肉。此次疫情引发了人们对大肠杆菌O157疫情中食品制备和处理标准、交叉污染问题以及加强当地溶血性尿毒综合征监测必要性的关注。
