摘要：

The incidence of AFB1 (B1) was determined in 72 wheat derivatives samples (Biscuits, bread, cornflakes, flour, macaroni and wheat bran. Positive sample for biscuits, bread and flour (16.7%), cornflakes (8.33%), macaroni (33.33%) and wheat bran (50%). Sixteen samples were contaminated with B1 ranging from 0.21 to 2.17 mu g/kg. PCR was used for the detection of B1 contamination based on aflatoxin biosynthetic genes af1R, af1S, af1D, af1M and af1P. The interpretation of the results revealed that PCR is a rapid and sensitive method.
