Impact of Season, Demographic and Environmental Factors on Salmonella Occurrence in Raccoons (Procyon lotor) from Swine Farms and Conservation Areas in Southern Ontario

Using a repeated cross-sectional study conducted over 3 years, our objectives were to: 1) compare Salmonella prevalence, Salmonella serovars, and antimicrobial resistance patterns detected in Salmonella from raccoon and environmental samples on swine farms and conservation areas; and 2) assess the impact of seasonal, climatic, annual, location, and raccoon demographic factors on the occurrence of Salmonella in raccoon fecal and environmental samples.
