      Objective To investigate the contamination and distribution of foodborne pathogens in foods sold in Liaoning province from 2017 to 2019. Methods A total of 4694 samples of 12 categories were collected in Liaoning province from 2017 to 2019, and the food borne pathogens were detected and analyzed according to the National handbook for risk monitoring of food pollutants and harmful factors. Results The total detection rate of various pathogenic bacteria in 4694 samples was quite different, and Bacillus cereus had the highest detection rate of 12.78%. The detection rates of pathogenic bacteria in rice noodle products, infant milk powder and complementary food and aquatic products and their products in different types of food were higher, which were 15.02%, 14.81% and 12.46%, respectively. The highest pathogen detection rate of bulk samples in different packages was 9.55%, and the highest pathogen detection rate of online stores in different sampling sites was 14.06%. Conclusion There are different degrees of food borne pathogenic microorganism pollution in the food sold in Liaoning province, among which rice and noodles products, infant milk powder and supplementary food and aquatic products and their products are seriously polluted by food borne pathogenic microorganism, and the regulatory department should strengthen its supervision and management.
