摘要

摘要: 目的了解泰州市食品及腹泻病例中沙门菌检出分布情况。方法采集市售食品样品339份、肉制品生产过程样品201份及病例粪便标本1 606份，按照食品安全国家标准方法对沙门菌进行鉴定及血清学分型。结果 2015-2017年泰州市9类食品中沙门菌检出率为4.4%（15/339），其中生禽肉、生畜肉和生食动物性水产品检出率分别为27.5%、7.5%、2.5%；肉制品生产过程中沙门菌检出率为6.5%（13/201），原辅料和中间产品检出率分别为35.7%和28.6%；3所医疗机构腹泻病例沙门菌年平均检出率为4.9%（79/1 606），5岁以下人群检出率（7.3%）高于其他年龄组（χ²=20.63，P < 0.01）。腹泻病例可疑暴露食品居前3位的分别为禽、畜肉（28.6%）、乳制品及饮料（25.0%）和水果类（25.0%）。市售食品和患者中共鉴定出21种沙门菌血清型。结论泰州市市售食品中沙门菌存在较高的污染率，腹泻病例沙门菌具有较高的检出率，应加强食品的监测、监管和宣传教育。

Abstract: Objective To study the distribution of Salmonella in food and diarrhea cases in Taizhou City. Methods 339 samples of commercially available food, 201 samples of meat production process and 1 606 stool samples of diarrhea cases were collected. Salmonella was identified and serologically classified according to national food safety standards. Results The detection rate of Salmonella in 9 types of foods form 2015 to 2017 was 4.4% (15/339), and the detection rates of raw poultry, raw meat and raw aquatic products were 27.5%, 7.5% and 2.5%, respectively. Among the samples collected during the meat production process, the total detection rate of Salmonella was 6.5% (13/201), and the detection rates of raw materials and intermediate products were 35.7% and 28.6%, respectively. From 2015 to 2017, the average detection rate of Salmonella in stool samples collected from 3 medical institutions was 4.9% (79/1 606). The detection rate of children under 5 years old (7.3%) was higher than other age groups (χ²=20.63, P < 0.01). Among the suspected food items for diarrhea, the top three were poultry and livestock (28.6%), dairy products (25.0%) and fruits (25.0%). A total of 21 Salmonella serotypes were identified from commercially available food and patient samples. Conclusions There is a high pollution rate of Salmonella in commercial food and a high detection rate in diarrhea cases in Taizhou City. Food monitoring, supervision and publicity education should be strengthened.
