Abstract：Objective To analyze the epidemiological features of foodborne diseases in Yantai City from 2019 to 2020, and to provide a scientific basis for formulating prevention and control measures. Methods We collected the information about cases of foodborne diseases from 168 sentinel hospitals, and analyzed the data regarding clinical diagnosis, food exposure and laboratory testing. Results A total of 104,516 cases of foodborne diseases were reported by the 168 hospitals in Yantai City from 2019 to 2020. The high-incidence period of the diseases was from June to September (58.69%). The age group with the highest incidence was 55-64 years old (18.30%), followed by 65-74 years old (15.79%). The occupational distribution of the cases was dominated by farmers (60.38%). Fruits and their products (30.79%) and aquatic animal products (18.09%) were the main suspected foods. Most of the cases occurred in families (89.62%). 427 biological samples of the cases were collected, and 81 strains of viruses and pathogenic bacteria were detected (18.97%), including 35 strains of Salmonella, 20 strains of Vibrio parahaemolyticus, 13 strains of norovirus, and 12 strains of diarrheal Escherichia coli. Conclusion The networked surveillance system for foodborne diseases in Yantai City has achieved a comprehensive coverage of urban, town and village areas, and the monitoring data can reflect the incidence of foodborne diseases more accurately. It is necessary to develop corresponding prevention and control measures according to the epidemiological characteristics of local cases of foodborne diseases so as to reduce the occurrence offoodborne diseases.
