目的了解乌鲁木齐市畜禽肉储存与销售环节细菌的污染状况,为细菌引起的食源性疾病的防控提供依据。方法依据食品安全国家标准中相关食品微生物检验标准和《全国食源性致病菌监测工作手册》,对乌鲁木齐市部分畜禽肉储存库、超市及农贸市场进行随机采样检测。结果在200份样品中共检出20株致病菌,总检出率为10.0%。其中沙门菌检出率最高,为4.5%,其次为单核细胞增生李斯特菌(2.5%),检测过程中未发现大肠杆菌O157∶H7。结论乌鲁木齐市畜禽肉储存与销售环节不同程度受到沙门菌和单核细胞增生李斯特菌的污染,以生鸡肉污染最严重。应加强禽畜屠宰、畜禽肉加工及销售等过程产品的检疫、检测及卫生监管,减少食源性疾病的发生。
Objective To understand the pollution status of bacteria in storage and sale of livestock and poultry meat in Urumqi and provide basis for the prevention and control of foodborne diseases caused by bacteria. Methods Based on the relevant national food microbiological testing standards and the National Foodborne Pathogenic Bacteria Monitoring Manual, some samples of livestock and poultry meat stores, supermarkets and farmers’ markets in Urumqi were randomly sampled and tested. Results A total of 20 pathogenic bacteria were detected in 200 samples with a total detection rate of 10.0%. Among them, the highest detection rate of Salmonella was 4.5%, followed by Listeria monocytogenes (2.5%). No Escherichia coli O157: H7 was detected during the test. Conclusion The storage and sale of livestock and poultry meat in Urumqi were polluted by Salmonella and Listeria monocytogenes to varying degrees, and the contamination of raw chicken was the most serious. The quarantine, testing and hygiene supervision of process products such as slaughtering of livestock and poultry meat, processing and sales of livestock and poultry meat should be strengthened so as to reduce the incidence of food-borne diseases.
