An innovative survey was designed based on annual numbers of slaughtered pigs from intensive and outdoor farms in France. A total of 1549 samples of cardiac fluids were collected from pig hearts to determine seroprevalence using a Modified Agglutination Test. Of those, 160 hearts were bio-assayed in mice to isolate live parasites. The overall seroprevalence among fattening pigs was 2\u00b79%. The adjusted seroprevalence in pigs from intensive farms was 3\u00b70%; the highest in sows (13\u00b74%); 2\u00b79% in fattening pigs and 2\u00b76% in piglets. Adjusted seroprevalence in fattening animals from outdoor farms was 6\u00b73%. Strains were isolated from 41 animals and all were genotyped by Restriction Fragment Length Polymorphism as type II. Risk-factor analysis showed that the risk of infection was more than three times higher for outdoor pigs, and that sows\u2019 risk was almost five times higher than that of fattening animals. This study provides further evidence of extensive pork infection with<jats:italic>T. gondii<\/jats:italic>regardless of breeding systems, indicating that farm conditions are still insufficient to guarantee \u2018<jats:italic>Toxoplasma<\/jats:italic>-free pork\u2019.<\/jats:p>","DOI":"10.1017\/s0031182015001870","type":"journal-article","created":{"date-parts":[[2016,3,1]],"date-time":"2016-03-01T11:19:44Z","timestamp":1456831184000},"page":"557-567","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":47,"title":["<i>Toxoplasma gondii<\/i>infection in pork produced in France"],"prefix":"10.1017","volume":"143","author":[{"given":"V.","family":"DJOKIC","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"BLAGA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"AUBERT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"DURAND","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"PERRET","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"GEERS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"DUCRY","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"VALLEE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O.","family":"DJURKOVIC DJAKOVIC","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"MZABI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"VILLENA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"BOIREAU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2016,3,1]]},"reference":[{"key":"S0031182015001870_ref10","doi-asserted-by":"publisher","DOI":"10.1645\/GE-2811.1"},{"key":"S0031182015001870_ref43","doi-asserted-by":"publisher","DOI":"10.1016\/j.cimid.2014.03.001"},{"key":"S0031182015001870_ref5","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182011001041"},{"key":"S0031182015001870_ref11","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.321.7254.142"},{"key":"S0031182015001870_ref48","doi-asserted-by":"publisher","DOI":"10.1645\/GE-3032.1"},{"key":"S0031182015001870_ref22","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-4017(99)00138-7"},{"key":"S0031182015001870_ref42","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2012.12.001"},{"key":"S0031182015001870_ref56","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2004.07.003"},{"key":"S0031182015001870_ref37","doi-asserted-by":"publisher","DOI":"10.1186\/1297-9716-42-17"},{"key":"S0031182015001870_ref51","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182009991065"},{"key":"S0031182015001870_ref1a","volume-title":"R: A Language and Environment for Statistical Computing","year":"2010"},{"key":"S0031182015001870_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2013.12.017"},{"key":"S0031182015001870_ref35","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.04-0326"},{"key":"S0031182015001870_ref30","doi-asserted-by":"publisher","DOI":"10.1111\/j.1863-2378.2012.01514.x"},{"key":"S0031182015001870_ref27","doi-asserted-by":"publisher","DOI":"10.1016\/j.parint.2010.06.001"},{"key":"S0031182015001870_ref4","unstructured":"Association BD PORC (2013).
