| Abstract | ||
| We collected 30 samples of cereal crops (Wheat, millet, barley, corn, and rice) stored and offered for sale in Riyadh area markets. It was found that most of these samples were contaminated with fungus Aspergillus sp.(73.2% ), and that the corn crop was highest to be hit by fungus Aspergillus sp. (23.3%) compared to the rest of the crops (wheat 16.6 %), ( barley 13.3%), (millet 10%), and (rice 10%). It appeared in this study that most isolated species have the ability to produce aflatoxin. We studied the effect of temperature on the secretion of aflatoxin in isolated fungi; and the results are illustrated in the temperature table. | ||
