Abstract: In this paper, the status of contamination associated with pathogenic microorganisms in raw milk of dairy cows with mastitis is introduced, the prevalence of antimicrobial resistant pathogenic microorganisms causing dairy cows mastitis is expounded, and the corresponding control measures on pathogenic microorganisms associated contamination in raw dairy milk are proposed. Many species of pathogenic microorganisms such as Escherichia coli, Staphylococcus aureus, Streptococcus spp. and Klebsiella spp. are observed in raw milk of dairy cows with mastitis. The presence of pathogenic microorganisms in mastitis milk samples are varied in different regions, and the pattern of antimicrobial resistance as well as the distribution of antimicrobial resistant determinants of the mastitis associated pathogenic microorganisms are also different. This review provides a reference for reducing drug residues and drug resistance due to abuse of antibiotics, controlling the contamination associated with pathogenic microorganisms in raw milk of dairy cows with mastitis, and improving the prudent and rational use of antibiotics.

Key words: mastitis, raw milk, contamination status, control measures
