The U.S. Food and Drug Administration (FDA) has approved the Iowa Department of Agriculture and Land Stewardship’s (IDALS) request to allow corn containing more than 20 parts per billion (ppb) of aflatoxin to be blended with corn with lower levels or no aflatoxin for animal feed. This allows the corn to be safely fed to livestock pursuant to the FDA’s long-standing guidelines.
Before doing any blending of corn containing aflatoxin, the grain dealers and the IDALS must sign a compliance agreement. The compliance agreement outlines the requirements for grain dealers that will be blending corn containing aflatoxin.
