Technical Abstract: Certain fungi can accumulate toxic metabolites, termed mycotoxins, in grains and other commodities. Mycotoxins can pose a serious threat to food safety and security, reduce crop value, act as virulence factors promoting crop diseases, and negatively impact animal health and productivity. Mycotoxigenic fungi are responsible for billions of dollars in lost agricultural production and economic activity each year in addition to their negative impacts on human health. The mycotoxins of greatest significance in grains are the aflatoxins, fumonisins, ochratoxin A, the trichothecenes, and zearalenone. In this chapter, we describe the structural diversity and chemical properties of these mycotoxins, introduce the major mycotoxigenic fungi, summarize the effects of mycotoxin exposure in humans and animals, discuss methods for monitoring of these toxins in grains, and provide an overview of regulatory limits and guidance.
