Abstract: The contamination of fresh milk with pathogenic microorganisms seriously affects the quality and safety of milk and its products. This paper analyzed the sources of contamination by pathogenic microorganisms, and analyzed the hazards of 37 pathogenic microorganisms that may be carried in raw milk and have an impact on consumers' health, and clarified the risk ranking of pathogenic microorganisms that need to be controlled as a priority, so as to provide technical references for the recognition, prevention and control, and risk assessment of pathogenic microorganisms in the whole industrial chain of raw milk in China. At the same time, combining the different production modes of raw milk in China, this paper proposed measures to reduce the pathogenic microorganisms that affect consumers' health: the breeding process should strengthen the microbiological control of feed, barn and cattle; the milking process should strengthen the microbiological control of milking tools, milking staff, and medicine bath; the storage and transportation process should strengthen the microbiological control during storage and transportation. These targeted prevention and control strategy recommendations will promote relevant parties to follow up on raw milk quality and safety control in a timely manner to reduce the risk of dairy consumption.

Key words: raw milk, pathogenic microorganisms, source of contamination, hazard analysis, abatement measure
