The aim of the present study was to determine the prevalence of  Salmonella  in the pork production chain and to characterize  Salmonella  isolates. From 764 samples, 35 (4.6%) were positive for  Salmonella  spp., as determined by biochemical tests and the presence of the  invA  gene. From these, 2.6, 2.0, 8.8, and 8.0% corresponded to samples collected from farms, slaughterhouses, boning rooms and retail markets, respectively.  Salmonella  strains were classified into five serotypes and distributed as follows:  S.  Typhimurium in the pork production chain,  S . Kentucky in farms and slaughterhouses,  S . Brandenburg in slaughterhouses , S . Livingstone in farms and  S . Agona in boning rooms and retail markets. Interestingly, the antimicrobial susceptibility testing indicated that all 35  Salmonella  spp.-positive isolates were resistant to at least one antimicrobial agent, and 30 were multidrug-resistant (MDR) and resistant to different classes of antibiotics. The enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR) analysis showed clonal relatedness among strains isolated from farms, boning rooms and retail markets. The presence of antibiotic-resistant  Salmonella  in food poses a potential health hazard to consumers.
