USDA Weighs Whether Bug-Resistant Engineered Corn Gets a Regulatory Pass

## Summary

Pioneer Hi-Bred International wants the USDA to say their new genetically engineered corn, COR-ØØ121-4, is safe and doesn’t need special rules. This corn fights off certain bugs using a special protein, which could help farmers protect their crops better. The USDA is asking the public to review and comment on this by January 8, 2027, before making a final decision.

## Abstract

We are advising the public that the Animal and Plant Health Inspection Service has received a petition from Pioneer Hi-Bred International, Inc. seeking a determination of nonregulated status for COR-[Oslash][Oslash]121-4 maize (corn), which has been developed using genetic engineering to express the IPD083Cb protein for protection against certain susceptible lepidopteran pests and the phosphomannose isomerase protein that was used as a selectable marker. We are making the petition and draft plant pest risk assessment available for public review and comment.
