The document discusses alternative uses for grain contaminated with aflatoxins, which are toxic substances produced by fungi that can grow in grains like corn under certain conditions. It notes that aflatoxin contaminated grain can be used in industries like wet milling, ethanol production, and as animal feed when under regulated limits. For animal feeds, levels are considered acceptable under 20 parts per billion but anything over 10ppb is rejected, though during shortages levels up to 80ppb may be allowed if a clay-based binder is added. Managing aflatoxin contamination poses challenges including the expense of testing, accuracy of tests, and legal limits not aligning with testing capabilities or allowing for different end uses or use of binders
