The stool samples of patients were collected for pathogen detection, and the prevalence status and causes of foodborne diseases were analyzed.ResultsIn Liaoning Province, the high risk group was the age of 25-44 years group (33.38%, 57 151/171 219). Cases were mainly in summer (65.35%, 111 896 /171 219). The detection rate of Vibrio parahemolyticus (4.37%, 867/19 845) was higher than the other pathogenic bacteria.

The most risky packaging was bulk food (41.79%, 70 941/169 743) and family was the most frequent place(70.65%, 119 517/169 157). The main clinical symptoms were digestive system symptoms (98.55%, 168 735/171 219) and diarrhea.ConclusionLiaoning Province should further improve the monitoring and reporting network of foodborne diseases, strengthen the surveillance of foodborne diseases among high-risk group, focus on the safety of seafood consumption, especially in summer, when making bulk seafood in families, and increase food safety and health education to avoid foodborne diseases.
