A study was undertaken in Alagoas, Brazil, to determine the prevalence, associated risk factors and antimicrobial susceptibility of Staphylococcus aureus in milk and cheese from artisan handman dairies. Alleged S. aureus isolates (n = 70) were identified out of 100 samples. Most isolates (66%) derived from raw milk and 34% came from cheese. Two hundred (50%) subclinical and 20 (40%) clinical cases out of 250 cross-breed lactating dairy cows examined for mastitis with CMT screening test and clinical examination, were found positive. Current study shows that the prevalence of Staphylococcus aureus was significantly associated with mastitis (p<0.05) and revealed that S. aureus has 0% susceptibility to penicillin G, followed by tetracycline (15%). However, these randomly selected isolates were found to be totally (100%) susceptible to kanamycin. There should be a regular antimicrobial sensitivity testing, not only in the area under analysis, but also at a national level to select effective antibiotics against S. aureus mastitis. Proper prevention and regular antimicrobial sensitivity testing help select effective antibiotics and ultimately reduce the development of resistance towards commonly used antibiotics. Results demonstrate that mastitis caused by S. aureus is one of the major issues in milk production and imposes public health hazard in the area under analysis. Every possible control and prevention strategies should be implemented.
