2014年金华市食源性疾病监测结果分析

Surveillance of foodborne diseases in Jinhua in 2014

目的了解金华市食源性疾病发生的基本情况,为预防和控制食源性疾病提供更为准确、充分的科学依据。方法对金华市食源性疾病主动监测、食源性疾病暴发报告结果进行统计分析。结果 2014年哨点医院共监测食源性疾病病例4 095例,男女比例1.33∶1,以20~59岁年龄组为主(52.60%,2 154/4 095),职业以农民为主;采集粪便标本3 927份进行特定病原体检测,共检出致病菌120株,其中副溶血性弧菌55株、沙门菌46株、志贺菌18株、致泻性大肠埃希菌1株。2014年共报告食源性疾病暴发事件14起,发病人数125人,以致病菌导致的感染性腹泻为主,5~8月为高发期,副溶血性弧菌的检出率最高。结论食源性疾病监测结果反映金华市食源性疾病发生处于低水平,应重点加强监测关键环节的质量控制,建议进一步扩大主动监测的覆盖范围。

Objective To obtain the data of foodborne disease incidence from a multipurpose surveillance in Jinhua.Methods Active symptom surveillance of foodborne diseases from sentinel hospitals and the reports of food poisoning outbreaks from networks were analyzed. Results Totally 4 095 foodborne disease cases were reported and the ratio of male and female was 1. 33 ∶ 1. The majority was within the age of 20-59 years group（ 52. 60%）,most of whom were farmers.Among 3 927 cases of foodborne disease,one hundred and twenty pathogenic bacteria were detected,in which fifty-five strains were Vibrio Parahaemolyticus,forty-six were Salmonella,eighteen were Shigella,and 1 strain was Enteropathogenic Escherichia coli（ EPEC）. Fourteen outbreaks of food poisoning involving one hundred and twenty-five people were reported. The results of the surveillance showed that the peak of foodborne diarrhea incidence was from May to August,and was also the peak of Vibrio Parahaemolyticus detection. Conclusion The surveillance of foodborne disease generally reflected the low incidence of foodborne disease in Jinhua. The quality control of the key sectors should be emphasized and active surveillance should be expanded.
