集体食堂副溶血性弧菌食物中毒的样品采集探讨

目的分析副溶血性弧菌食物中毒发生的污染食品和可疑的污染来源,探讨副溶血性弧菌食物中毒处置的样品采集,提高检出率,增强事故处理效度和信度。方法结合实验室数据,总结17起副溶血性弧菌所致集体食堂食物中毒资料进行统计学分析。结果引发17起副溶血性弧菌所致集体食堂食物中毒主要原因是食品储存和保洁不当而受到副溶血性弧菌污染所致。其中,受污染的食物以熟肉为主,占总起数的35.29%。而副溶血性弧菌采样阳性检出率最高的为病人肛拭子,达54.50%:其次是剩余食物中的副溶血性弧菌,检出率为13.28%。结论微生物性食物中毒取证困难,但我们应及时有效地控制关键环节,同时根据副溶血性弧菌的生物学特性,结合流行病学原理,高效地掌握科学证据,快速、准确地处置事故,为群众保障安全的餐饮环境。

Explored the Sample Collection of Food Poisoning Caused by Vibrio Parahaemolyticus in Collective Canteen

OBJECTIVE To analyse the pollution food and the pollution sources of food poisoning caused by vibrio parahaemolyticus, explore the sample collection of food poisoning caused by vibrio parahaemolyticus , to improve the detection rate and enhance the validity and reliability. METHODS Collected the data of food poisoning cases caused by vibrio parahaem olyticus, analyzed with statistical methods. RESULTS All of the events occurred in collective eatery of factory. The main cause was improper preservation and cleaning of food. The poisoning food was cooked meat which accounted for 35.29%, and the detection rate of pathogen in stool samples was highest（54.50%）, then was the surplus food（13.28%）. CONCLUSION It＇s difficulty to take a evidence for microorganisms food poisoning, but we can control critical segment on time, according the biological characteristics of vibrio parahaemolytieus and the principle of epidemiology, we can grasp the scientific evidence efficiently and disposal the accident for quick, malicious, precision, given people a softy dining environment.
