DES MOINES, Iowa - Iowa farmers can now start using corn with aflatoxin to be blended into corn used for animal feed.
The U.S. Food and Drug Administration says Iowa corn containing more than 20 parts per billion of aflatoxin can be blended with corn with lower levels or no aflatoxin for livestock only.
Before doing any blending of corn containing aflatoxin, the grain dealers and the Iowa Department of Agriculture and Land Stewardship must sign a compliance agreement.
Each batch of blended corn must be analyzed to determine the aflatoxin level.
The blended corn must be clearly identified and labeled for animal feed use only and corn containing aflatoxin levels greater than 500 parts per billion cannot be blended.
Aflatoxins are a group of chemicals produced by certain mold fungi.
They can occur more frequently in hot, dry summer conditions.
Iowa State University extension has more information about aflatoxin.
