Humans are exposed to aflatoxins by consuming foods contaminated with products of fungal growth. Because aflatoxins, especially aflatoxin B1, are potent carcinogens in some animals, there has beengreat interest to study the effects of long-term exposure to low levels of these important mycotoxins on humans.The main aim of present study was to develop specific PCR and ELISA (using recombinant antibody) methods for the direct detection of aflatoxin B1 in contaminated food and food products.In this study, different food samples were collected from the Egyptian market and Aflatoxin B1 was determined by HPLC and by VICAM’s monoclonal antibodies based commercial strips.Results showed that 78% of collected food samples were contaminated by Aflatoxin B1. The contaminated samples were subjected to detectionby specific PCR of the afiR gene (aflatoxin B1 gene) and the PCR results confirmed the results observed by the two previous methods.
