2017年青岛市食源性疾病主动监测细菌学结果分析

Analysis of surveillance results of bacterial foodborne disease in Qingdao,2017

目的了解青岛市细菌性食源性疾病的发生趋势,流行特征,为今后食源性疾病的防治提供依据。方法对2017年青岛市2家哨点医院符合食源性疾病定义的就诊者进行信息采集,留取粪便进行病原学检测。结果从466例食源性疾病患者粪便标本中共检出阳性60例,检出率为12. 88%,主要为致泻性大肠埃希菌(34例)、副溶血性弧菌(24例)、沙门菌(2例)。阳性病例在二、三季度有明显高峰。阳性病例以20岁～50岁人群发病率最高;职业分布以工人和家务及待业人群最多;食品以肉与肉制品为主,其次是水产动物及其制品和水果类及其制品。结论青岛地区以致泻性大肠埃希菌和副溶血性弧菌为主,季节高峰较明显,应针对各病原检出率的差异在不同季节开展不同的防控措施。

Objective To understand the trends and epidemiological characteristics of bacterial food borne disease in Qingdao, so as to provide basis for the prevention and control of this disease.Methods Information collection was carried out on the patients with food-borne diseases from two sentinel hospitals in Qingdao in 2017,and feces were taken for pathogenic testing.Results A total of 60 positive samples were detected from 466 specimens of patients with foodborne diseases,and the detection rate was 12.88%,mainly including Escherichia coli (34cases ),Vibrio parahaemolyticus (24 cases),and Salmonella (2 cases).Positive cases showed significant peaks in the second and third quarters.The positive cases were the highest in the 20-50 years old population;the occupational distribution was the largest among workers,households and the unemployed; contaminated food was mainly meat and meat products,followed by aquatic animals and their products,fruits and their products.Conclusion Diarrheic Escherichia coli and Vibrio parahaemolyticus were the main pathogens for food borne diseases, showing an obvious seasonal peak.So,different prevention and control measures should be carried out in different seasons according to the detection rate difference of each pathogen.
