Abstract: Food safety incidents caused by harmful microorganisms in dairy products have received extensive attention and become a research hotspot in the environment of public health. In this paper,progress of harmful microbial detection technology and safety control method in dairy products reviews and analyzes using recent domestic and foreign researches from the perspective of dairy safety. Among the detection technologies,PCR technology,ELISA and immunomagnetic bead separation technology,LAMP technology and others are mainly introduced. The safety control methods mainly involve ultra-high pressure treatment technology,ultra-high pressure homogenization technology and pulse character style. It is aimed to provide theoretical and technical support for the safety production of dairy products,which has far-reaching practical significance.
