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
Salmonella enterica subsp. enterica (S.) serovar Derby is one of the most prevalent serovars in pigs. The aim of this study was the investigation of S. Derby isolates for the presence of antimicrobial resistance and class 1 integrons and their gene cassettes. Forty-nine S. Derby isolates, obtained from different sources at four pig abattoirs (A-D) in Southern Brazil were analysed. Five isolates were susceptible to all antimicrobial agents tested.
