Sera were collected twice, 50\u201361 weeks apart, from 592 workers at eight abattoirs slaughtering sheep (<jats:italic>n<\/jats:italic>\u00a0=\u00a04), cattle (<jats:italic>n<\/jats:italic>\u00a0=\u00a02) and deer (<jats:italic>n<\/jats:italic>\u00a0=\u00a02), and tested by the microscopic agglutination test for Hardjo and Pomona. Forty-nine (8\u00b73%) participants either seroconverted or had at least a twofold increased serological titre against either serovar. The worker infection risk was higher in sheep abattoirs (11\u00b79%) than in abattoirs processing deer (0%) or cattle (1\u00b72%) (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00\u00b701). The annualized risk of mild (ILI) or severe clinical disease attributable to the two<jats:italic>Leptospira<\/jats:italic>serovars was 2\u00b77%. This study has demonstrated that meat workers are at substantial risk of infection and clinical disease, suggesting further investigation of infection sources and preventive measures are warranted.<\/jats:p>","DOI":"10.1017\/s0950268814002477","type":"journal-article","created":{"date-parts":[[2014,9,30]],"date-time":"2014-09-30T11:33:08Z","timestamp":1412076788000},"page":"2095-2105","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":21,"title":["Risk of infection and associated influenza-like disease among abattoir workers due to two<i>Leptospira<\/i>species"],"prefix":"10.1017","volume":"143","author":[{"given":"A.","family":"DREYFUS","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"HEUER","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"WILSON","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"COLLINS-EMERSON","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
