Abstract

ObjectiveTo analyze the epidemiological characteristics of rural banquet foodborne disease outbreaks in China from 2010 to 2020 and provide a reference for formulating rural banquet foodborne disease prevention and control measures.MethodsData on foodborne disease outbreaks in rural banquet reported in the China Foodborne Disease Outbreak Surveillance System from 2010 to 2020 were statistically analyzed.ResultsFrom 2010 to 2020， a total of 1 421 foodborne disease outbreaks were reported in rural banquets， with 31 078 cases， 64 deaths， a fatality rate of 0.21%， and an average of 22 cases per outbreak.
