International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork
Iowa State University Conferences and Symposia

The SafePork conference series began in 1996 to bring together international researchers, industry, and government agencies to discuss current Salmonella research and identify research needs pertaining to both pig and pork production. In subsequent years topics of research presented at these conferences expanded to include other chemical and biological hazards to pig and pork production.

Abstract

The prevalence of Salmonella contamination was assessed at five points in a Canadian pork slaughter plant. In the cooler only 0.5% (2/429) carcasses were positive, even though Salmonella were detected in 51.3% of all cecal samples and in the cecum of at least one pig in 91.5% (43/47) lots tested. Hogs held overnight in lairage were significantly more likely to have positive cecal samples. Salmonella was isolated at least once from the truck, holding pen or cecum of hogs from all 31 producers.
