Every type of grain can be affected by mycotoxins. The toxins can accumulate in maturing corn, wheat, soybeans, sorghum, peanuts and other food and feed crops in the field, during transportation or improper storage.
The occurrence of mycotoxins in food and animal feed often shows a geographic pattern, as for example Aspergillus species find optimal conditions in tropical and subtropical regions, whereas Fusarium and Penicillium species are also adapted to the moderate climate of North America and Europe. However, worldwide trade with food and feed commodities result in a worldwide distribution of contaminated material.
