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 objectives of this study were to investigate Salmonella carriage at each stage of pig production (farrow to finish) on 10 commercial pig farms having a historically high Salmonella seroprevalence and to establish the role of feed as a source of Salmonella on the farms. Pig faecal (n=458) and feed (n=321) samples were taken across all pig production stages and analysed for the presence of Salmonella. The pathogen was detected in pigs on nine farms, in 58/458 (12.7%) faecal samples, with a high prevalence among gilts, weaners and finishers.
