An investigation, involving twenty environmental health departments in addition to health authorities and the Public Health Laboratory Service, showed an association between the illness and eating loose sliced cooked ham (<jats:italic>P<\/jats:italic> = 0.004). Detailed tracing of the chain of supply of the ham showed this to be particularly cooked ham originating from a single small local producer (<jats:italic>P<\/jats:italic> = 0.00003). Further investigation of that producer revealed that a batch of ham distributed on one day in early April was undercooked due to a malfunction in cooking equipment.<\/jats:p>","DOI":"10.1017\/s0950268800057198","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T08:50:24Z","timestamp":1242377424000},"page":"465-472","source":"Crossref","is-referenced-by-count":16,"title":["The problems of tracing a geographically widespread outbreak of salmonellosis from a commonly eaten food: <i>Salmonella typhimurium<\/i> DT193 in North West England and North Wales in 1991"],"prefix":"10.1017","volume":"111","author":[{"given":"L.","family":"Thornton","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Gray","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Bingham","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
