This study determined the antibiogram of methicillin-resistant Staphylococcus aureus (MRSA) strains from traditionally-pasteurised dairy product (Kindirmo) in parts of Nasarawa, Nasarawa State, Nigeria. One hundred and sixty samples were collected from January 2021 – April 2021. Standard microbiological procedures were used in isolating and identifying MRSA strains from the samples. Characterisation of the MRSA strains was carried out using Microgen® kits. The MRSA strains were evaluated for their susceptibility to eight commonly used antibiotics using the Kirby-Bauer technique. Of the 160 samples examined, five MRSA strains were obtained, giving a prevalence of 5.0%. All of the MRSA strains were resistant to cefoxitin, 62.5% were resistant to tobramycin, and 25.0% were resistant to chloramphenicol. Five (5) antibiotic resistant phenotypes were recorded among the MRSA strains. The occurrence of MRSA in Kindirmo as recorded in this study, suggest that, the consumption of the product constitute a hazard to consumers. Basic hygiene requirements during production and selling of the product should be imposed by relevant authorities. This will go a long way in ensuring the safety of the product.
