A review of the 2026 corn season found that a warmer, drier spell during silking increased potential aflatoxin risk farther north than usual. The article recommends that feed mills use risk-based mycotoxin testing that adapts to incoming grain, supplier, geography and test results.
Elevated aflatoxin risk can lead mills to test more often, segregate grain or avoid higher-risk corn, tightening the supply of usable feed and raising handling costs. The article describes a potential quality risk rather than a quantified crop loss or broad price move.
After 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
