From tests on corn grain this year, vomitoxin and zearelenone are the two primary mycotoxins showing up. But, there are many different types as described in the information below in the NebGuides.

Feedlot cattle are the most logical place to use feeds high in mycotoxins and level will dictate the amount used. Distillers grains could contain mycotoxins if the grain contains them. Because the starch is removed from the grain, which is 2/3 of the composition of the kernel, the mycotoxins are concentrated by two or three times in distillers. This may or may not be much of an issue, and ethanol plants will have to be diligent.

For feedlots that are using their home grown corn grain, if there appears to be a problem with the corn grain, consider sampling the grain and testing for mycotoxins.
