目的了解广州市市售食品中食源性致病菌的污染状况,为食源性疾病的监测和预警提供科学依据。方法2015年-2016年对广州市6类共计2 044份食品样品,依据《广州市食品安全风险监测工作手册》的要求,进行金黄色葡萄球菌、单核细胞增生李斯特菌、沙门菌、副溶血性弧菌、蜡样芽胞杆菌5种致病菌的检测和分析。结果在2 044份样品中检出致病菌241株,总检出率为11.79%。水产品致病菌检出率为59.10%,生鲜肉为7.28%,焙烤食品为7.24%,即食食品为5.83%,快餐或小摊食品为5.29%,熟肉制品为4.32%。副溶血性弧菌检出率高达56.36%,其次为蜡样芽胞杆菌(3.68%)、金黄色葡萄球菌(1.56%)、单核细胞增生李斯特菌(1.13%)、沙门菌(0.49%)。结论广州市食品存在食源性致病菌污染,应有针对性地加强食品监督管理,以减少可能引起食源性疾病的因素。
Objective To understand the status of food-borne pathogens in Guangzhou and to provide a scientific basis for monitoring and early warning of food-borne diseases. Methods A total of 2 044 food samples were collected from 6 categories in Guangzhou City during 2015-2016. Staphylococcus aureus, Listeria monocytogenes, Salmonella typhi were added according to the requirements of “Guangzhou Food Safety Risk Monitoring Manual” Vibrio hemolyticus, Bacillus cereus five kinds of pathogenic bacteria detection and analysis. Results A total of 241 pathogenic bacteria were detected in 2 044 samples with a total detection rate of 11.79%. The detection rate of pathogenic bacteria of aquatic products was 59.10%, raw fresh meat was 7.28%, baked goods was 7.24%, ready-made food was 5.83%, fast food or stall food was 5.29% and cooked meat products was 4.32%. The detection rate of Vibrio parahaemolyticus was 56.36%, followed by Bacillus cereus (3.68%), Staphylococcus aureus (1.56%), Listeria monocytogenes (1.13%), Salmonella (0.49%), . Conclusion Food-borne pathogens in Guangzhou are contaminated. Food supervision and management should be strengthened in a targeted manner to reduce the possible causes of food-borne diseases.
