Abstract: [Objective] To analyze the status of school food poisoning in China from 2006-2014,explore the epidemiological characteristics,and provide basis for taking effective measures to control the occurrence of food poisoning in schools.[Methods] The statistical mean,morbidity,mortality,composition ratio,x2 test and Fisher's exact probability method were used to describe the overall situation of school food poisoning from 2006-2014,analyze the influence of different pathogenic factors on the school food poisoning,compare with the national poisoning situation,and describe the epidemiological characteristics.[Results] A total of school food poisoning events were reported 655 outbreaks from 2006-2014,including 28 134 cases and 25 death cases,and the mortality rate and fatality rate was 0.11/lakh and 0.89‰ respectively.56.58% of cases were caused by microbial pathogens,and 80% of death cases were caused by chemical agents.The proportion of events,cases and death cases in school to national cases was 13.65-33.87%,20.54-41.15% and 0.51-3.64%,respectively.After 2009,the average number of the annual poisoning events and cases decreased by 77.96% and 58.06% respectively,but the case number in every event rose by 47.46%,and the ratio of unexplained death cases increased by 16.67%.[Conclusion] Microbial poisoning and chemical poisoning are the focus of prevention and control in the future.The Food Safety Law of the People's Republic of China,which has been issued and implemented in 2009,has a certain impact on food poisoning in schools.The reasons for substantial decline of school food poisoning since 2009 need further research and investigation.
