A total of 202 pigs that had been serologically monitored monthly during the fattening period and from which mesenteric lymph nodes (<jats:styled-content style=\"fixed-case\">MLN<\/jats:styled-content>) and faecal (<jats:styled-content style=\"fixed-case\">SFEC<\/jats:styled-content>) samples were collected at slaughter for <jats:italic>Salmonella<\/jats:italic> isolation were included. A repeated\u2010measures <jats:sc>anova<\/jats:sc> was used to assess the relationship between mean <jats:styled-content style=\"fixed-case\">OD<\/jats:styled-content>% values during the fattening period and sampling time and bacteriology on <jats:styled-content style=\"fixed-case\">MLN<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">SFEC<\/jats:styled-content>. Pigs were also grouped into four groups, that is pigs seronegative during the fattening period and <jats:italic>Salmonella<\/jats:italic> negative in <jats:styled-content style=\"fixed-case\">MLN<\/jats:styled-content> (group A; <jats:italic>n\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>69); pigs seronegative during the fattening period but <jats:italic>Salmonella<\/jats:italic> positive in <jats:styled-content style=\"fixed-case\">MLN<\/jats:styled-content> (B; <jats:italic>n\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>36); pigs seropositive at least once and <jats:italic>Salmonella<\/jats:italic> positive in <jats:styled-content style=\"fixed-case\">MLN<\/jats:styled-content> (C; <jats:italic>n\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>50); and pigs seropositive at least once but <jats:italic>Salmonella<\/jats:italic> negative in (D; <jats:italic>n\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>47). Pigs shedding at slaughter seroconverted much earlier and showed much higher mean <jats:styled-content style=\"fixed-case\">OD<\/jats:styled-content>% values than non\u2010shedders pigs. The proportion of <jats:italic>Salmonella<\/jats:italic> shedders in groups A and D was high and similar (26.1% and 29.8%, respectively), but significantly lower than that for groups B and C. The odds of shedding <jats:italic>Salmonella<\/jats:italic> for groups B and C were 4.8 (95% CI\u00a0=\u00a01.5\u201315.5) and 20.9 (3.7\u2013118) times higher, respectively, when compared to A. It was concluded that a large proportion of <jats:italic>Salmonella<\/jats:italic> seronegative pigs may shed <jats:italic>Salmonella<\/jats:italic> at slaughter, which would be likely associated to previous exposure with contaminated environments (i.e. transport and lairage). For pigs already infected at farm, the likelihood of shedding <jats:italic>Salmonella<\/jats:italic> was much higher and may depend on whether the bacterium has colonized the <jats:styled-content style=\"fixed-case\">MLN<\/jats:styled-content> or not. The odds of shedding <jats:italic>Salmonella<\/jats:italic> spp. were always much higher for pigs in which <jats:italic>Salmonella<\/jats:italic> was isolated from <jats:styled-content style=\"fixed-case\">MLN<\/jats:styled-content>.<\/jats:p>","DOI":"10.1111\/zph.12301","type":"journal-article","created":{"date-parts":[[2016,8,23]],"date-time":"2016-08-23T06:12:40Z","timestamp":1471932760000},"page":"328-336","source":"Crossref","is-referenced-by-count":17,"title":["Influence of On\u2010farm pig <i>Salmonella<\/i> status on <i>Salmonella<\/i> Shedding at Slaughter"],"prefix":"10.1111","volume":"64","author":[{"given":"A.","family":"Casanova\u2010Higes","sequence":"first","affiliation":[{"name":"Unidad de Producci\u00f3n y Sanidad Animal Centro de Investigaci\u00f3n y Tecnolog\u00eda Agroalimentaria de Arag\u00f3n Instituto Agroalimentario de Arag\u00f3n \u2010IA2\u2010 (CITA\u2010Universidad de Zaragoza) Zaragoza Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Andr\u00e9s\u2010Barranco","sequence":"additional","affiliation":[{"name":"Unidad de Producci\u00f3n y Sanidad Animal Centro de Investigaci\u00f3n y Tecnolog\u00eda Agroalimentaria de Arag\u00f3n Instituto Agroalimentario de Arag\u00f3n \u2010IA2\u2010 (CITA\u2010Universidad de Zaragoza) Zaragoza Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5442-7702","authenticated-orcid":false,"given":"R.
