Discussion and conclusions: High prevalence of Campylobacter coli was detected in both ABF and conventional production systems. This is consistent with previous findings that Campylobacter is common among pigs. The interesting aspect, however, was that even though the prevalence was higher among conventionally-raised pigs on-farm, the opposite was true when carcass swabs were considered. As the pigs from ABF were slaughtered in an abattoir separate from the one used for conventional pigs, the result may be due to an abattoir effect. Significant reduction of prevalence was also noticed in all positive pig groups in post-chill samples. This was particularly true for the conventionally-raised groups. This can be explained by the presence of blast chiller system in the abattoir where the conventionally-raised pigs were slaughtered. Frequency of antimicrobial resistance among Campylobacter from the two production systems revealed that at the level of on-farm, frequency of resistance to the antimicrobials tested was lower among ABF pigs than conventionallyraised pigs. Even though this is not conclusive, as the study is still on-going, the findings so far have consistent trend. On the other hand the ABF pigs harbored higher frequency of resistant organisms from carcass swabs than conventional ones. This may be due to multiple factors including cross contamination at slaughter or sampling error.
