北京市平谷区2018年食源性疾病主动监测结果分析

目的 对北京市平谷区2018年食源性疾病哨点医院的主动监测结果分析, 了解食源性疾病的发病及流行趋势。方法 收集哨点医院主动监测的符合食源性疾病病例定义的347例病人的信息, 对采集的粪便标本进行沙门菌、副溶血性弧菌、致泻性大肠埃希菌、志贺菌、诺如病毒等5种食源性致病微生物的病原学检测。结果 347例食源性疾病患者26~35岁年龄组患者所占的比例最大(32.0%)。疾病发生的场所主要为家庭(80.4%)。在明确的可疑原因食品中, 肉与肉制品所占比例最大(20.7%)。共采集332份患者粪便标本, 检测出致病菌者79例, 检出率23.8%。沙门菌检出率最高(10.2%)、其次为致泻大肠埃希菌(9.6%)。抽取264份标本进行诺如病毒检测, 14份检出阳性, 检出率5.3%。第3季度致病菌检出率高于其他季度, 12、1、2、3月份诺如病毒检出率较高。结论 应加强平谷区食源性疾病的季节性监测, 对易感人群、家庭进行食品卫生知识重点宣传教育, 尤其是肉与肉制品相关知识。

Analysis of proactive monitoring results of food-borne diseases in Pinggu district of Beijing in 2018

Meat and meat products accounted for the largest proportion (20.7%) of the dubious food. A total of 332 feces samples were collected from the patients and 79 were found positive in pathogenic bacteria detection with a positive rate of 23.8%. The detection rate of Salmonella was the highest (10.2%), followed by Escherichia coli(9.6%). A total of 264 samples were selected for norovirus detection, and 14 were found positive (5.3%). The third quarter of the year was found had the highest detection rate of pathogenic bacteria and the detection rate of norovirus in December, January, February and March were higher.
