Abstract Objective To investigate the monitoring results of 4 common foodborne pathogenic microorganisms in food in Dalian from 2012 to 2017, and to provide scientific basis for the effective prevention and control of foodborne diseases. Methods According to the requirements of Liaoning Province foodborne disease surveillance work plan, four common foodborne pathogenic microorganisms were monitored in 2831 samples collected from 18 categories from 2012 to 2017, and the data were collated and the results were analyzed. Results The highest detection rate of Vibrio parahaemolyticus in 2831 samples was 12.11%. Among the different years, the highest detection rate of pathogenic bacteria was 4.68% in 2016. The detection rates of pathogenic bacteria in aquatic products, fresh water products, meat and meat products were 7.37%, 6.32% and 3.63%, respectively. The highest detection rate of pathogenic bacteria in bulk samples in different packages was 2.44%. The highest detection rate of pathogenic bacteria in different sampling sites was 4.10%. Conclusion There is a hidden danger of foodborne pathogenic microorganism infection in food safety in Dalian, and the pollution of aquatic products is serious. Targeted research on whether it is related to climate and water quality is the direction to be explored in the future. Meanwhile, it is suggested to strengthen disinfection supervision in farmers' markets to prevent the occurrence of food poisoning and ensure the food safety of residents.
