目的为了解山东省食品污染状况,修订食品污染物限量标准,进行食品污染状况评价和预警提供可靠数据。方法采用《全国食品污染物监测相关实验室操作技术手册(细菌部分)》的方法对样品进行沙门氏菌、大肠艾希氏菌O157:H7、单核细胞增生李斯特氏菌、弯曲菌、副溶血弧菌等5种食源性致病菌的检测。结果对生肉、熟肉(散)、蔬菜、水产品等食品的病菌进行检测,检测样品1 833份,分离菌株共268株,包括:沙门氏菌38株、单增李斯特氏菌133株、出血大肠O157 0株、弯曲菌18株、副溶血弧菌79株,总阳性菌株268株,占总检测数的14.6%。讨论食源性致病菌污染相对较高,肉及肉制品尤为严重,建议在食品加工制作各个环节减少污染,避免食源性疾病发生。食源性致病菌的主动监测是一项连续性的工作,应加强主动监测,保证食品安全。
Objective To understand the status of food contamination in Shandong Province, revise the limit standards of food contaminants and provide reliable data for food contamination assessment and early warning. Methods Salmonella, Escherichia coli O157: H7, Listeria monocytogenes, Campylobacter, and parahemolytic arc were used in the method of "Operational Manual of National Laboratory for Food Contamination Control (Bacteria) 5 kinds of bacteria and other foodborne pathogens detection. Results A total of 1 833 samples were tested for the pathogens of raw meat, cooked meats, vegetables, aquatic products and so on. A total of 268 isolates were isolated, including 38 strains of Salmonella, 133 strains of Listeria monocytogenes, O157 strains, 18 strains of Campylobacter, 79 strains of Vibrio parahaemolyticus and 268 strains of total strains, accounting for 14.6% of the total. Discussion of foodborne pathogens relatively high pollution, meat and meat products is particularly serious, it is proposed to reduce pollution in all aspects of food processing and production, to avoid foodborne diseases. Proactive monitoring of food-borne pathogens is a continuous effort and should be proactively monitored to ensure food safety.
