Few have reported the prevalence and antimicrobial susceptibility of Salmonella in organic and ethnic meats. The objective of this study was to assess the prevalence and antimicrobial susceptibility of Salmonella spp from organic (n=120), kosher (n=107), kosher/organic (n=26), and conventional/all natural (n=120) raw retail chicken samples, as well as to characterize these isolates by serotyping. Salmonella was isolated from all sample types. Isolates were confirmed by Polymerase Chain Reaction (PCR). Antimicrobial susceptibility was assessed for all confirmed isolates by the agar disk diffusion method and a total of 151 confirmed strains were serotyped. Overall, prevalence of Salmonella was higher in organic samples. However, organic and kosher isolates showed higher antimicrobial susceptibility than isolates from the other sample types. The most prevalent serovars were Kentucky, Enteriditis, Heidelberg, and Typhimurium. Findings from this study suggest an influence of poultry production system in the prevalence and antimicrobial susceptibility of Salmonella in raw chicken.
