Transmission of Salmonella, Yersinia Enterocolitica, Campylobacter, MRSA and Antimicrobial Resistance within Swine Breeding Pyramids in Ontario


<OL> <LI> To investigate whether the farms supplying replacement breeding stock are a source for the introduction of Salmonella, Yersinia enterocolitica, Campylobacter, and MRSA to commercial pig farms,

<LI> To determine if the antimicrobial resistance patterns of these pathogens are similar for the herds supplying breeding stock and the farms purchasing the animals,

<LI>To determine the risk factors associated with the presence of foodborne pathogens and multidrug resistance on commercial farms.

Expected Benefits:
If this research proves that replacement gilts are a source of foodborne pathogens including multi-drug resistant pathogens, then appropriate biosecurity and control measures may be considered to reduce the spread of these disease agents.

Reducing the prevalence of foodborne pathogens and in particular multi-drug resistant bacteria will reduce contamination through food chain and increase consumer confidence.
