      目的 了解2011~2019年吉林省米面制品中食源性致病菌的污染情况。方法 根据《国家食源性疾病监测工作手册》对2011~2019年吉林省9个地(市)所采集到的米面制品食品样本中蜡样芽孢杆菌、金黄色葡萄球菌、单增李斯特菌进行检测。结果 2011~2019年共检测米面制品3967份, 其中阳性菌株313株, 总检出率为7.89%, 2015年检出率最高(14.68%)。蜡样芽孢杆菌在白山市检出率最高(44.44%), 金黄色葡萄球菌在白城市检出率最高(7.89%), 单增李斯特菌在白山市检出率最高(6.21%)。餐饮服务环节总阳性检出率为9.72%, 流通环节总阳性检出率为5.38%。蜡样芽孢杆菌在炒的米面制品中检出率最高(43.42%), 金黄色葡萄球菌和单增李斯特菌均在速冻面米生制品中检出率最高, 检出率分别为7.61%和14.29%。结论 吉林省各地市米面食品污染的情况普遍存在, 白山市最严重, 但是近年来污染情况正在逐步好转。餐饮服务环节需加强管理, 小吃店、零售加工店和百货商场应该给予更严格的把控。速冻米面生制品污染相对严重, 需给予重视。

英文摘要:

      Objective To understand the contamination status of foodborne pathogens in rice and noodle products in Jilin province from 2011 to 2019. Methods According to the National foodborne disease surveillance work manual, the Bacillus cereus, Staphylococcus aureus, and Listeria monocytogenes in the food samples of rice and noodle products collected from 9 prefectures (cities) levels Jilin province from 2011 to 2019 were detected. Results From 2011 to 2019, a total of 3967 rice and noodle products were tested, including 313 positive strains, with a total detection rate of 7.89%. The detection rate was the highest in 2015 (14.68%). The detection rate of Bacillus cereus was the highest in Baishan city (44.44%), the detection rate of Staphylococcus aureus was the highest in Baicheng city (7.89%), and the detection rate of Listeria monocytogenes was the highest in Baishan city (6.21%). The total positive detection rate of catering services was 9.72%, and that of the catering service was 5.38%. Bacillus cereus had the highest detection rate in fried rice noodle products (43.42%), and both Staphylococcus aureus and Listeria monocytogenes had the highest detection rate in quick-frozen rice noodles, which was 7.61% and 14.29%, respectively. Conclusion Rice and noodle food pollution is common in various cities in Jilin province and Baishan city is the most serious. However, in recent years, the situation is gradually improving. The management of catering services needs to be strengthened. Snack shops, retail processing stores and department stores should be more strictly controlled. The pollution of quick-frozen rice and noodle products is relatively serious, which should be paid attention to.
