Human salmonellosis originating from pork is an important zoonotic disease, and the objective of this study was to determine whether the Salmonella shedding was lower for pigs herds provided wet-feed compared to those on traditional dry rations. Four wet-feeding farms and six dry-feeding farms were selected. Individual faecal and feed samples were collected (faces 30, feed 10 from pigs per farm), and analysed for the presence ofSalmonella. The results showed a low level of on-farm Salmonella shedding (overall prevalence from faecal samples 2.0% as well as 1.0% of the feed samples). The overall prevalence was 30% in studied farms (3 out of 10). Two of the dry-feeding farms (33.33%) tested positive compared to only one of the wet-feeding farms (25%). Salmonella was isolated in 5 of 180 faecal samples from farms with dry-feeding, compared to farms with wet-feeding where it was isolated in only one sample out of 120. Salmonella was also recovered from the feed on one dry-feeding farms but were not isolated from the farms using wet-feeding. These findings indicate that farms with wet-feeding are associated with lower (p<0.01) prevalence of Salmonella.
