Abstract: Foodborne pathogenic bacteria are the major risk of food safety,  causing great harm to human health. Thus, it is urgent to research and establish an accurate and effective detection method for foodborne pathogenic bacteria. With the rapid development of single-molecule techniques, digital PCR has been widely used in detection of foodborne pathogenic bacteria due to their outstanding advantages, such as high sensitivity, high stability and low reagent consumption. This review mainly summarized the basic principles and research progress of digital PCR. The applications of digital PCR technology in detection of Escherichia coli, Salmonella, Staphylococcus aureus, Campylobacter jejuni, Shigella, Cronobacter, Vibrio parahaemolyticus, Listeria monocytogenes and Bacillus cereus were also discussed, which would provide further insight into the detection of foodborne pathogenic bacteria.

Key words: detection of foodborne pathogenic bacteria, digital PCR, droplet digital PCR
