摘　　要：目的了解2009—2013年广州市市售食品中黄曲霉毒素B1污染水平,为广州市开展居民膳食中黄曲霉毒素B1风险评估提供基础数据。方法在广州市10个区的农贸市场、超市、批发市场、餐饮单位、加工场以及零售店等随机采集米及米制品（大米及米粉）、面及面制品（小麦粉及面包）、植物油（花生油、玉米油）、花生（熟制及生花生）、玉米粉（渣、碎）、油炸食品以及大豆共7类食品,采用国家标准测定方法（ELISA）进行黄曲霉毒素B1的含量测定。结果 820份样品中共260份被检出黄曲霉毒素B1,检出率为31.71%,检出值范围为0.012~39.300μg/kg,均值为2.675μg/kg,中位数为2.5μg/kg,食品总体合格率为98.66%。结论广州市市售粮油食品黄曲霉毒素B1总体污染水平不高,但植物油（花生、玉米）检出率较高。Objective To investigate the contamination of aflatoxin B~ in food and oil in Guangzhou, and provide the basic data of dietary intakes of aflatoxin Bl for food safety assessment. Methods The samples of seven kinds of food including rice, wheat flour, peanut and corn oil, peanut, corn flour, fried food and soybean from ten regions were collected randomly from farmer＇s markets, supermarkets, wholesale markets, and catering units. The national standard detection method for aflatoxin B1 （ELISA） was taken to detect the content of aflatoxin B1. Results 260 samples were detected aflatoxin B1 and the detection rate was 31.71% , and the farmer＇s markets had the highest detection rate. The detection range was 0. 025 -39. 300 μg/kg, with the mean value of 2. 675 μg/kg and the median of 2.5 μg/kg. The overall qualified rate was 98.66%. Conclusion The overall level of aflatoxin B~ contamination in market food was low, but some foods such as vegetable otis （peanut, corn） should be more concerned.
