EPA Okays Mutant Corn Protein, Skipping Pesky Residue Rules

## Summary

The EPA just gave a green light to Syngenta Seeds by exempting their special protein, eCry1Gb.1Ig, from pesticide residue limits on corn. This means farmers and food makers can use this protein in corn without worrying about strict residue rules, starting August 7, 2026. If anyone has concerns, they have until October 6, 2026, to speak up—making it easier and cheaper to grow safer corn!

## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of Bacillus thuringiensis eCry1Gb.1Ig protein in or on the food and feed commodities of corn, field; corn, sweet; and corn, pop when used as a plant-incorporated protectant (PIP) in corn. Syngenta Seeds, LLC submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of eCry1Gb.1Ig protein under FFDCA when used in accordance with the terms of the exemption.

## Effects PRIA read

- Tolerance exemption for eCry1Gb.1Ig in corn: benefit, low. If you are an agricultural producer, food manufacturer, or pesticide/seed business, residues of the Bacillus thuringiensis eCry1Gb.1Ig protein in or on field corn, sweet corn, and popcorn are exempt from the requirement of a pesticide tolerance when used as a plant-incorporated protectant in corn.…
- EPA finds eCry1Gb.1Ig not harmful to people: benefit, medium. EPA concluded there is a reasonable certainty that residues of the eCry1Gb.1Ig protein in or on corn will not harm people, including infants and children, and therefore established the exemption. The Agency found no oral toxicity or allergenicity in studies cited and determined no extra 10x safety…
