Abstract:Abstract：Foodborne pathogenic bacteria are an important cause of disease and seriously threaten human health.Strengthening the inspection of microorganism in food can effectively curb the occurrence of social public health problems，consolidate the detection technology of microorganism，and constantly innovate the detection technology.Starting from the microbial detection technology application and comparison，the droplet digital polymerase chain reaction（PCR）technique，ethidium monoazide bromide-polymerase chain reaction（EMAPCR），visualize，gene chip technology and fluorescent tags phage，in recent years the emergence of new detection technology was discussed.
