Large outbreak of infection with Escherichia coli O157 PT21/28 in Eccleston, Lancashire, due to cross contamination at a butcher's counter.
An outbreak of infection with Escherichia coli O157 Phage Type 21/28 occurred between the 23rd November 2001 and the 7th December 2001 in Eccleston, Lancashire. There were 30 confirmed cases (23 with positive faecal isolates and seven serologically positive). Eccleston is a village of approximately 5,000 inhabitants with a single medical practice where many of the cases were patients. Initial investigations identified the suspected source as a butcher's counter, operated as a franchise, in a supermarket in Eccleston. The butcher closed voluntarily on the 24th November. The median age of cases was 60 with a mean of 56 and a range of 2-91 years. Of the 30 confirmed cases, 22 were admitted to hospital. Two patients developed serious complications but all 30 made a full recovery. Microbiological investigations confirmed the butcher's counter as the source of the outbreak. The epidemiological evidence implicated cooked meats and microbiological evidence confirmed that contamination had occurred between raw and cooked meats. The deficiencies in meat hygiene practice that were identified could have led to the cross contamination. This outbreak illustrates the risk associated with the handling of raw and cooked meats in the same shop. Complete physical separation of raw and cooked meat operations reduces the risk of such outbreaks.
