中文摘要:

      目的 了解河南省预包装糕点食品的微生物污染状况, 为食品安全监督管理部门提供科学依据。 方法 根据GB/T 4789.24-2003《食品卫生微生物学检验 糖果、糕点、蜜饯》标准方法的要求, 对河南省多个地区抽送检的604份预包装糕点样品(其中冷加工糕点109份, 热加工糕点495份)进行菌落总数、大肠菌群、金黄色葡萄球菌、沙门氏菌和霉菌计数检测。结果 604份预包装糕点样品中, 8份热加工糕点菌落总数超标, 3份冷加工糕点菌落总数超标, 1份冷加工糕点霉菌计数超标, 大肠菌群、金黄色葡萄球菌和沙门氏菌检测的结果均未超标。结论 预包装糕点中存在菌落总数和霉菌计数超标的问题, 致病菌污染的风险较低, 相关部门应继续加强对预包装糕点食品安全的监管力度, 保障食品安全。

      Objective To investigate the microbial contamination of pre-packaged pastry in Henan province so as to provide scientific basis for food safety supervision and management departments. Methods According to the GB/T 4789.24-2003 Food hygiene microbiology test-candy, pastry, candied fruit, a total of 604 samples of pre-packaged pastry (109 portions of cold processed pastries and 495 portions of hot processed pastries) were collected from various areas of Henan province, for detection of the total number of colonies, coliform bacteria, Staphylococcus aureus, Salmonella and mold counts. Results Among 604 samples of pastries, the total number of colonies of 8 hot processed pastries and 3 cold processed pastries exceeded the standard, the mold count of 1 cold processed pastries exceeded the standard, while the results of coliform bacteria, Staphylococcus aureus and Salmonella were all below the limit of standard. Conclusion Pre-packaged pastry exist the limit-exceeding problem of the total number of colonies and mold counts, and the risk of pathogen contamination is low. The relevant departments should continue to strengthen the safety supervision of pre-packaged pastry food and ensure food safety.
