These contamination levels present MEDIUM to HIGH risk for all livestock and poultry species depending on toxin and feed ingredient type.

Overall, producers in the Midwest should be on the lookout for the impacts from deoxynivalenol and zearalenone, while Southern states should be vigilant regarding fumonisin and aflatoxin contamination.
