Corn planting will soon wrap up in the United States, and the National Corn Growers Association is reminding farmers that unused seed is not to be mixed with commodity grain. 

The vast majority of seed corn is treated with one pesticide or another prior to planting. The Food and Drug Administration considers mixing pesticide-treated seed in commodity shipments as adulterated grain. FDA may take enforcement actions against processed food or feed products that contain seed corn treated with pesticides. 

There have also been recent incidences of treated seed showing up in export channels, leading to trade disruptions. Corn growers are encouraged to contact the seed dealers and representatives if they have any questions about safe disposal methods.
