Important for farmers to keep grain impacted by flood waters completely separate

DES MOINES – Iowa Secretary of Agriculture Bill Northey today reminded farmers that grain impacted by flood waters, whether in the field or in a bin, is considered adulterated and cannot be used for feed or food. The grain still in the field should be destroyed and not blended with uncontaminated grain.

“There is the potential for a wide variety of contaminants to enter grain through flood waters, so any corn or soybeans that have been submerged are considered adulterated and must be destroyed,” Northey said.

In the rare situations where the water flooding the field was not contaminated, the grain may be reconditioned. Before being sold, the grain must be reconditioned with the written consent of the U.S. Food and Drug Administration (FDA). The floods of 2010 in Iowa contained uncontrolled flood waters that are considered contaminated.

Flood damaged grain is considered adulterated under Chapter 198.7 of the Iowa Code. The Code prohibits the manufacturing or distribution of any food or feed from ingredients that are adulterated.

A short fact sheet further outlining the handling of flood damaged grain can be found on the Iowa Department of Agriculture and Land Stewardship’s website at
