目的了解天津市市售食品致病菌污染状况,为提出针对性预防措施提供依据。方法模拟消费者采集市售食品,按照2012年《全国食源性致病菌监测工作手册》方法检验其中可能存在的致病菌。结果 2012年在天津市全市范围内共采集肉制品、水产品等9类1 350份食品样品,共有60份样品检出致病菌(病毒),阳性率为4.4%。婴幼儿食品、水产品和熟制米面制品阳性率较高,分别为13.3%、13.0%和8.7%。结论水产品中副溶血性弧菌污染较为普遍,婴幼儿食品中的蜡样芽胞杆菌值得关注,应建立市售食品致病菌持续监测机制。
Objective To understand the status of food-borne pathogen contamination in Tianjin and to provide the basis for proposing preventive measures. Method to simulate the consumer to collect commercially available food, in accordance with the 2012 “national foodborne pathogens monitoring manual” method to test which may exist in the pathogenic bacteria. Results In 2012, a total of 1 350 food samples of 9 categories including meat products and aquatic products were collected in the city of Tianjin. A total of 60 samples were detected for pathogens (viruses), with a positive rate of 4.4%. The positive rates of infant food, aquatic products and cooked rice noodles were higher at 13.3%, 13.0% and 8.7% respectively. Conclusion The contamination of Vibrio parahaemolyticus in aquatic products is more common. Bacillus cereus in infant food is worth noting. A continuous monitoring mechanism should be established for commercial pathogenic bacteria in food.
