EPA Sets Safe Limits for Deadly Hydrogen Cyanide in Your Food?

## Summary

The EPA just updated the rules for certain pesticides like hydrogen cyanide to keep our food safe and the environment protected. Farmers, food makers, and pesticide companies should note these changes, which take effect April 22, 2026. If anyone wants to challenge the new rules, they have until June 22, 2026, to speak up—no extra costs, just clearer safety standards!

## Abstract

The Environmental Protection Agency (EPA or Agency) is finalizing several tolerance actions under the Federal Food, Drug, and Cosmetic Act (FFDCA) that the Agency previously determined were necessary or appropriate during the registration review conducted under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). During registration review, EPA reviews all aspects of a pesticide case, including existing tolerances, to ensure that the pesticide continues to meet the standard for registration under FIFRA.

## Effects PRIA read

- Finalized Pesticide Tolerance Changes: cost, low. You are an agricultural producer, food manufacturer, or pesticide company if you use or make pesticides like hydrogen cyanide, 1-naphthaleneacetic acid, carboxin, ethofumesate, thiobencarb, or propylene oxide. The EPA finalized new or revised residue tolerances for these active ingredients that tak…
- Food Safety Protected by Tolerances: benefit, low. You as a food consumer benefit because EPA set legal residue limits (tolerances) to help keep food safe from residues of pesticides such as hydrogen cyanide and propylene oxide. These tolerances are final on April 22, 2026 and specify parts-per-million limits for many commodities to guide safe leve…
- Ethofumesate Tolerance Expiration Extended: benefit, low. EPA changed the expiration date for a specific ethofumesate tolerance (for 'Beet, sugar, tops') from December 8, 2025 to October 19, 2026. This gives producers and exporters extra time to adapt to the lowered or revoked tolerance level before that particular tolerance expires.
- EPA Finds No Significant Small-Business Impact: benefit, low. EPA certified under the Regulatory Flexibility Act that this final rule will not have a significant economic impact on a substantial number of small entities. The Agency states this action has no net burden on small entities subject to the rulemaking.
