In Denmark human cases are generally infrequently diagnosed. In 2005 an outbreak of diarrhoea affected company employees near Copenhagen. In all 99 employees were reported ill; 13 were positive for<jats:italic>Cryptosporidium hominis<\/jats:italic>infection. Two analytical epidemiological studies were performed; an initial case-control study followed by a cohort study using an electronic questionnaire. Disease was associated with eating from the canteen salad bar on one, possibly two, specific weekdays [relative risk 4\u00b71, 95% confidence interval (CI) 2\u00b71\u20138\u00b73]. Three separate salad bar ingredients were found to be likely sources: peeled whole carrots served in a bowl of water, grated carrots, and red peppers (in multivariate analysis, whole carrots: OR 2\u00b71, 95% CI 1\u00b71\u20134\u00b70; grated carrots: OR 2\u00b71, 95% CI 1\u00b72\u20133\u00b79; peppers: OR 3\u00b73, 95% CI 1\u00b77\u20136\u00b76). We speculate that a person excreting the parasite may have contaminated the salad buffet.<\/jats:p>","DOI":"10.1017\/s0950268808001817","type":"journal-article","created":{"date-parts":[[2009,1,9]],"date-time":"2009-01-09T16:09:43Z","timestamp":1231517383000},"page":"348-356","source":"Crossref","is-referenced-by-count":69,"title":["A foodborne outbreak of<i>Cryptosporidium hominis<\/i>infection"],"prefix":"10.1017","volume":"137","author":[{"given":"S.","family":"ETHELBERG","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"LISBY","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.
