A survey of total aflatoxin levels was conducted on 565 food samples (cereals, nuts, etc) collected in commercial markets. The determination of aflatoxins (, , and ) was performed using HPLC with fluorescence detector. The Limit of Detections (LODs) of the B group and G group were 0.05 ng/g and 0.07 ng/g, respectively. In addition, recoveries of rice, peanut butter, and red pepper flour were satisfactory. Total aflatoxin was detected 27 samples(4.8%) out of 565 samples. Incidence ratios in cereals, nuts, processed products, and other foods were 0.2, 0.4, 3.0 and 1.2%, respectively, but aflatoxin was not detected in pulse and dried fruits. The daily intake of total aflatoxin using food intakes was 0.04 ng/kg bw/day.
