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
Food products of animal origin might play a role in interspecies transmission of C. difficile. In pigs, Clostridium difficile can cause neonatal enteritis and can be isolated from faeces from both diseased and healthy animals. To determine the prevalence of C. difficile in Dutch pigs arriving at the slaughterhouse a pilot study was conducted at one slaughterhouse in the Netherlands. Rectal faecal samples were taken from fifty slaughtering pigs from ten farms just after the pigs were sedated. These samples were examined using a real time PCR (BD GeneOhmTM Cdiff Assay), in combination with culturing after enrichment. Using real time PCR, none of the faecal samples were found to be positive for C. difficile while after culturing 14 samples (coming from pigs from nine different farms) were found to be positive for C. difficile. The positive samples derived from 9 different farms and encompassed seven different ribotypes.
