Analysis on the incidence of food borne diseases and pathogenic bacteria detection in Sanya from 2017 to 2022
Objective To summarize the occurrence of food borne diseases in Sanya,from 2017 to 2022,analyze the pathogens and provide early warning for potential food safety risks.Methods The descriptive epidemiology method was used to analyze the data of food borne diseases in Sanya from 2017 to 2022,including the number of events,number of cases,pathogenic factors,time,place,etc..Results From 2017 to 2022,there were 289 food borne diseases reported in Sanya,23 802 exposed people,2 068 cases,401 hospitalized cases,no death cases.Food borne diseases occurred in four administrative regions of Sanya,among which,83 and 68 occurred in high-incidence areas(Tianya district,Jiyang district)respectively,with the composition ratio of 43.91％and 35.98％.The number of cases was 1 027,924,89 and 28,respectively,and the difference of incidence in 4 regions was statistical significance(P＜0.001).The outbreak of food borne disease events showed obvious seasonal distribution,the number of events was 29 and 23 in July and October,the number of cases was 395 and 294,respectively.Restaurants were the most common occurrence of food borne diseases,with 112 cases(59.26％).The main causes were animal toxins,plant toxins,viruses and bacteria,with 3,7,18 and 76 cases respectively,as well as 85 for unknown causes.The incidence difference was statistical significance(P＜0.001).The bacterial pathogens accounted for 40.21％,especially Vibrio parahaemolyticus.Conclusion The location,time and pathogenic bacteria had obvious distribution characteristics.Health education,supervision and management should be strengthened.At the same time,improve the monitoring ability of food borne diseases,and reduce the occurrence of food borne diseases.
