The Aspergillus fungus can germinate and grow on feed grains at moisture levels of 15 % or greater in the presence of warm (70 to 100° F) temperatures. Aflatoxin production by the fungus is optimal at moisture levels greater than 17.5 % and temperatures of 77 to 92° F. The toxin can infect a vari...
