Abstract
This work was undertaken in 2008 to estimate the prevalence of L. monocytogenes in French farrow-to-finish pig farms at the breeding pig level and to determine risk factors of contamination of sows by L. monocytogenes. A total of 730 feces (10 per farm) were sampled from sows in 73 pig farms. 172 samples were also taken during the fattening stage, at 43 of the 73 farms (4 per farm). Detection of L. monocytogenes was carried out according to the ISO 11290-1/A1 method and isolates were serotyped. Generalized Estimating Equations were used in order to determine risk factors associated to contamination of sows by L. monocytogenes.
