Salmonella is a major cause of food borne disease in the world, with an increasing concern for the emergence and spread of antimicrobial-resistant strains. A cross-sectional study was conducted between November 2016 and April 2017 in Dukem town. The purpose of the study was to determine the prevalence and identify the antimicrobial susceptibility pattern of Salmonella. Following the accepted methodologies and procedures, a total of 286 samples, including feces, carcass swabs, and retail meat, were collected and tested for Salmonella. Systematic random sampling and purposive sampling techniques were used to generate the desired data. Salmonella was present in the beef supply chain on average at a rate of 6.3% (95% CI: 3.9-9.7). Based on sample source, the specific incidence of Salmonella was 0.9%, 2.9%, and 12.7% in retail meat, feces, and carcass swabs, respectively. There was statistically significant difference along the beef supply chain (X2 = 14.3027, P < 0.05). Among the isolates, 94.4% (n = 17) were resistant at least to one of the antimicrobials. Multi-drug resistance was observed in 27.8% (n = 5) of the isolates. The study found the occurrence of Salmonella along beef supply chain with higher prevalence at meat retail shop and the variability in the susceptibility pattern of Salmonella isolates against the tested antimicrobials. Identifying Salmonella serotypes circulating in the area and regular monitoring of the health status of workers and hygienic condition of the slaughterhouse and meat retail shop is recommended.
