USDA deregulates corn developed using genetic engineering

Date:12-01-2023

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is deregulating Pioneer Hi-Bred International, Inc.’s (Pioneer) DP23211 corn. This corn was developed using genetic engineering to resist corn rootworm and tolerate glufosinate herbicides. After a thorough review, APHIS concluded that DP23211 corn is unlikely to pose a plant pest risk. 

The determination is based on the evaluation of the following:

• Information Pioneer submitted in its petition for deregulation

• USDA APHIS' analyses

• Public comments received in response to previous notices announcing the availability of the petition, draft environmental assessment (EA) and draft plant pest risk assessment (PPRA) 

USDA APHIS is publishing the Determination of Nonregulated Status, final EA, final PPRA, and response to public comments. These documents support APHIS’ review and analysis of any potential environmental impacts associated with deregulating DP23211 corn.
