Abstract: Objective To analyze the epidemiological characteristics of foodborne disease related to aquatic animals and their products in Wuhan City from 2018 to 2023,and provide data support for the development of food safety risk monitoring and prevention control plans for freshwater product. Methods Select foodborne disease cases reported from the Wuhan Foodborne Disease Surveillance System,and select "aquatic animals and their products" for "food classification". Retrieve eligible research subjects for epidemiological feature analysis. Results A total of 1 456 cases of foodborne disease related to aquatic animals and their products were reported in Wuhan from 2018 to 2023,with a reporting rate of 6.35%. The number of female cases was significantly higher than that of male cases（χ²=23.939,P<0.05）. The peak of cases was mainly concentrated from May to October,with the highest peak in August. There was a statistically significant difference in the number of reported cases between different months（χ²=61.988,P<0.05）. There was a statistically significant difference in reported incidence rate among different regions（χ²=237.631,P<0.05）,the number of reported foodborne diseases in the central urban area was significantly higher than that in the remote urban area. The difference of the number of cases among different age groups was statistically significant（χ²=331.161,P<0.05）,of which 65.59% were between 14 and 45 years old. The difference of the number of cases among different occupation population was statistically significant（χ²=386.177,P<0.05）,and the proportion of people engaged in housework and unemployment, students,cadres and staff,retirees,and business services was relatively high. The clinical diagnosis was mainly infectious diarrhea and acute gastroenteritis,accounting for 85.72%. The main eating places were catering service industry（42.87%）,retail/farmer's markets（22.53%）,and households（11.06%）. Most cases were caused by 2-10 people eating together（66.94%）. Conclusion There are obvious seasonal,regional,and population characteristics in foodborne cases related to aquatic animals and their products. This suggests that relevant departments should further strengthen the supervision of various links in the circulation of aquatic animals and their products,and also strengthen relevant health education.
