Yersinia prevalence in antibiotic free and convetionally reared swine

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.
These preliminary results compare the on-farm prevalence and frequency of carcass contamination with Yersinia enterocolitica (YE) for pigs reared under conventional and antibiotic free production systems. At the time of submission, results are available for 6 herds. In 5 of 6 herds, we were able to isolate YE from at least one pig on-farm. The overall individual pig prevalence was 13.3% on conventional farms 59.3% on ABF farms. YE was isolated from 2 of 191 carcass swabs. Although the preliminary nature of these results limits interpretation, it supports previous results that indicate swine serve as a reservoir for YE.
