Abstract: Staphylococcus aureus is one of the most important food borne pathogen. The presence of enterotoxigenic S. aureus in milk is a serious concern for human health. Drinking contaminated milk with preformed toxins of S. aureus causes rapid onset of food borne illness. A total of 100 milk samples including pooled milk (n=25), vendors milk (n=25), pasteurized market milk (n=25) and individual cow milk (n=25) were collected randomly from different parts of Udaipur city, Rajasthan. The prevalence of S. aureus in pooled milk, vendors milk, pasteurized market milk and individual cow milk was 76% (19/25), 36% (9/25), 0% (0/25) and 56% (14/25), respectively. The overall prevalence was 42% (42/100). Antibiotic susceptibility test results revealed that penicillin G and ampicillin showed highest resistance (100%) in bacteria followed by erythromycin (30.95%) and methicillin (21.43%).
