Technical Abstract: Corn production plays a major role in the US economy and is an essential part of the world’s grain supply supporting the exponentially growing human population either directly through consumption or indirectly through livestock feed. Mycotoxins are poisonous metabolites produced by fungal pathogens that infect corn and contaminate grain making it unsafe for consumption. Corn plants are susceptible to diverse mycotoxigenic fungi, and the amount and type of mycotoxin contamination is largely dependent on which fungal pathogen is favored by local weather conditions. The regional and annual economic losses associated with mycotoxins are summarized, and food safety concerns in the context of predicted climate changes are considered. Finally, the public research efforts to reduce mycotoxin occurrence are reviewed and critical research needs are discussed.
