For the swine industry, the control of Salmonella spp. bacteria has become a key element for market development and ensuring food safety of swine products to the consumer. The first objective of this project was to determine if the prevalence of Salmonella was higher in pigs raised on bedding – made of wood chips/sawdust – than in pigs raised on conventional partially slatted concrete floors. It also wanted to define the winning conditions of pig husbandry on bedding. The serological results show that the proportion of herds having a positive Salmonella test was 68% for the herds raised on bedding, versus 55% for the herds raised on partially slatted concrete floors. Moreover, Salmonella in the bedding of 27% of the herds raised on bedding, and in the feces of 24% of the herds raised on partially slatted floors has been observed. Nevertheless, the statistical analysis revealed that these differences were not significant. Generally speaking, many factors differ between those two types of husbandry methods without having a significant impact on the prevalence of Salmonella bacteria.
