The myc<strong>of</strong>lora and mycotoxins contamination <strong>of</strong> commercial maize and rice<br />
grains collected from local markets <strong>of</strong> the major five zones <strong>of</strong> the province <strong>of</strong><br />
Cairo, Egypt, represented by 20 different districts were studied. A total number <strong>of</strong><br />
about 23 species belonging to 12 different genera <strong>of</strong> fungi were isolated and<br />
identified. About 70% <strong>of</strong> the samples were infected with Aspergillus flavus and<br />
Aspergillus niger, with percentages <strong>of</strong> 33%, 40% recovered from maize and 46%,<br />
27% recovered from rice, respectively. The percentages <strong>of</strong> infection <strong>of</strong> maize<br />
ranged from 16% to 142%. The percentages <strong>of</strong> infection <strong>of</strong> rice seeds ranged<br />
from 6% to 93%. Total aflatoxins and fumonisins detected in maize averaged 9.75<br />
and 33 mg/kg, respectively. Total aflatoxins and fumonisins detected in rice<br />
averaged 5.15 and 1014 mg/kg, respectively.<br />
