Camel milk is one of the good sources of human nutrition intake, which is rich in nutritional value and easier to be absorbed and utilized.It plays an important role in human health and the prevention and treatment of diseases.However, due to the impact of unsanitary environmental conditions, non-standard production processes, or improper treatment methods, camel milk is extremely susceptible to microbial pollution, which not only threatens the quality and safety of camel milk products but also becomes one of the key factors restricting the sustainable and healthy development of camel milk industry.Therefore, microbial diversity in milk bottles, nipple clips, milk storage cans, nipples, drinking water, feed, feces, and camel house air samples was analyzed by 16S rRNA amplification technology.The Source Tracker analysis model was used to analyze the key risk points of microorganisms in three pastures.Results showed that the relative abundances of Lactococcus and Chryseobacterium in the raw milk of camel farm A were higher at the genus level, accounting for 52.37% and 15.76% respectively.The dominant genus of raw milk in camel farm B was Rothia, with a relative abundance of 83.64%.The bacteria genera with high proportions in the raw milk of camel farm C were Rothia and Acinetobacter, which were 64.85% and 17.58%, respectively.The Source Tracker model was used to analyze eight risk key points, including milk bottles, nipple clips, milk storage cans, nipples, drinking water, feed, feces, and camel house air samples from camel farms A, B, and C.The key risk points of raw milk microbial contamination were identified as nipples, nipple clips, milk bottles, and milk storage cans.These results can provide a reference for improving the safety of raw camel milk.
