南京市食源性疾病哨点医院主动监测结果分析
|
摘要
目的对2017年南京市食源性疾病哨点医院主动监测结果进行分析,进一步了解南京市食源性疾病的流行特征,为防控食源性疾病暴发事件提供参考依据。方法收集哨点医院符合食源性疾病病例定义的就诊病例信息,并采集粪便标本进行食源性病原体检测。结果 2017年共采集1 259份病例标本,在年龄分布上20～30岁年龄组发病最多,占24. 78%(312/1 259),食源性疾病的高发月份为6～7月,占病例总数的40. 91%(515/1 259),在明确的可疑食品中,肉与肉制品所占比例最大,为20. 33%(252/1 239)。2017年检出病原微生物阳性标本187份,检出率为14. 85%(187/1 259),其中沙门氏菌51株、副溶血性弧菌75株、志贺氏菌1株,致泻大肠埃希氏菌14株,诺如病毒28株。结论南京市食源性疾病发病率较高,以副溶血性弧菌、沙门氏菌、诺如病毒感染为主。应加强食源性疾病的主动监测,同时加强食品安全卫生监管,降低食源性疾病发生。
Objective TO analyze the monitoring results of foodborne diseases in Nanjing City in 2017,and to further understand the epidemiological characteristics of foodborne diseases in Nanjing,and provide reference for prevention and control of foodborne disease outbreaks. Methods TO collect the patients information on the case of foodborne diseases,and to collect stool samples for foodborne pathogen detection. Results A total of 1 259 case specimens were collected in 2017. In the age distribution,the 20-30 age group has the highest incidence,accounting for 24. 78%(312/1 259). The high incidence of foodborne diseases is from June to July,accounting for 40. 91%(515/1 259),Among the suspicious foods,meat and meat products accounted for the largest proportion,at20. 33%(252/1 239). 187 strains of pathogens were isolated,including 51 strains of Salmonella,75 strains of Vibrio parahaemolyticus,1 strains of Shigella,14 strains of diarrheogenic Escherichia coli and 28 norovirus,and the total detection rate was14. 85%(187/1 259). Conclusions The total detection rate of foodborne pathogenic bacteria in Nanjing City is high,and is mainly caused by Vibrio parahaemolyticus,Salmonella and norovirus. Active monitoring of foodborne diseases food safety should be strengthened,to reduce the incidence of foodborne diseases.
