Abstract:

Objective To analyze the epidemiological characteristic of biogenic foodborne disease outbreaks in Sichuan Province,so as to obtain the high-risk factors and the causes of food,and provide scientific basis for developing targeted prevention and control measures. Methods The epidemiological characteristics of biological foodborne disease outbreaks reported in national foodborne disease outbreak reporting system from 2019 to 2023 were analyzed. Results From 2019 to 2023,a total of 343 outbreaks of biological foodborne diseases were reported in Sichuan Province,with 3 140 cases and 2 deaths. The pathogenic factors were mainly bacteria,accounting for 97.08%(333/343),salmonella was the main type of bacteria,accounting for 72.30%(248/343). June had the most events,accounting for 20.70%(71/343). The Chengdu Plain Economic Zone reported the highest number of events,accounting for 69.39%(238/343). The number of families was the largest,accounting for 46.65%(160/343). The eggs and egg products reported the highest number of events,accounting for 54.81%(188/343). Eggs and egg products,as well as meat and meat products,each caused 1 death,accounting for 50.00%. Among the foodborne disease outbreaks caused by Salmonella,eggs and egg products were the main cause food(72.98%,181/248),and the main triggering factors were raw material contamination or spoilage(31.85%,79/248). Conclusion Salmonella poisoning and botulinum toxin poisoning remain the focus of prevention and control in Sichuan Province,and it is necessary to continue to strengthen public education for the public in summer and autumn and in key areas.
