A survey of total aflatoxin levels was conducted on 565 food samples (cereals, nuts, etc) collected in
commercial markets. The determination of aflatoxins (B1, B2, G1, and G2) 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.
