Abstract: Mastitis, inflammation of the mammary gland, is a highly prevalent problem in dairy cattle and is one of the most important threats affecting the worlds dairy industry. Staphylococcal mastitis is the most commonest and economically the greatest concern wherever dairy farming is practiced. Keeping in view of the public health significance of these food borne organism the present study was carried out by selecting 50 lactating cows from different small holder dairy farms to detect the presence of clinical and subclinical mastitis. Clinical inspection of the udder was carried by routine procedure. California mastitis test was carried out to diagnose the presence of subclinical mastitis. CMT positive milk samples were examined for the presence of S. aureus. Out of Fifty lactating cows examined during the study 9 (18%) animals had mastitis of which 2% (1/50) and 16% (8/50) showed clinical and subclinical mastitis respectively. Milk samples from one clinical mastitic animal (2 teats) and 8 CMT positive sub clinical cows (15 teats) showed the presence of S. aureus. The findings of this study revealed that S.aureus is the most prevalent organism in mastitis milk samples which is known to be the commonest causative for mastitis in animals.
