摘　　要：目的分析南通市中小学生食源性疾病流行病学特征,为有效防控中小学生食源性疾病提供科学依据。方法收集2015—2020年南通市哨点医院就诊的中小学生食源性疾病病例信息,并采集病例粪便标本进行病原体检测,运用χ^(2)检验比较不同学段中小学生食源性疾病病例的分布。结果共监测中小学生食源性疾病病例1432例。不同可疑暴露食品的分类和进食场所的病例数有统计学差异(χ^(2)=73.421;χ^(2)=66.857,P均<0.001),可疑暴露食品主要为肉与肉制品(28.21%)和水产动物及其制品(17.86%),可疑进食场所主要为家庭(57.60%)和学校食堂(12.69%)。疑似食源性疾病暴发事件主要发生在学校食堂。共采集标本214份,检出病原体22份,总体检出率为10.28%,阳性病原体以诺如病毒(3.74%)和副溶血性弧菌(3.27%)为主。结论需面向家庭、学校和学生开展有针对性的食品安全知识宣传,加强中小学生食源性疾病的重点食品和场所的食品安全监测和监管,最大限度地减少中小学生食源性疾病的发生。Objective To analyze the epidemiological characteristics of foodborne diseases among primary and secondary school students in Nantong,and to provide a scientific basis for effective prevention and control of foodborne diseases among primary and secondary school students.Methods Information on foodborne disease cases among primary and secondary school students attending sentinel hospitals in Nantong from 2015 to 2020 was collected,and fecal specimens of the cases were collected for pathogen detection.Theχ^(2) test was used to compare the distribution of foodborne disease cases among primary and secondary school students in different school periods.Results A total of 1432 cases of foodborne illness in primary and secondary school students were monitored.The number of cases was statistically different by classification of suspected exposed food and eating place(χ^(2)=73.421;χ^(2)=66.857,both P<0.001),and the suspected exposed food was mainly meat and meat products(28.21%)and aquatic animals and their products(17.86%),and the suspected eating places were mainly families(57.60%)and school canteens(12.69%).Suspected foodborne disease outbreaks occurred mainly in school canteens.A total of 214 specimens were collected and 22 pathogens were detected,with an overall detection rate of 10.28%,with positive pathogens mainly Norovirus(3.74%)and Vibrio parahaemolyticus(3.27%).Conclusion Targeted food safety information campaigns for families,schools and students are needed to strengthen food safety monitoring and supervision of key foods and sites for foodborne illness in primary and secondary school students to minimize the occurrence of foodborne.
