Antibiotic sensitivity test using Cefoxitin, Penicillin, Amphicillin, Oxacillin and Tetracyclin showed resistance 14(100%), 14(100%), 12(85,7%), 9(64,3%) and 0(0%) to the antibiotics in that order, 9 isolates were positive for MRSA. It was concluded that the raw milk can be a potential reservoir for MRSA strains which is a threat to public health.
