Twenty-one isolates of Aspergillus flavus Link were isolated from ten poultry feed stuff samples collected from different poultry farms at Assiut governorate using the dilution plate method on glucose-Czapek's agar medium incubated at 28 C. All Aspergillus flavus isolates were screened for their ability to produce aflatoxin on liquid medium culture. Chromatographic analysis revealed that aflatoxins B1, B2, G1 and G2 were present in the chloroform extracts of three isolates. The higher aflatoxin concentration produced by the different isolates was 280 mg per liter.
