EPA Lets Cinnamon Smell Skip Pesticide Residue Limits
Published Date: 6/26/2026
Rule
Summary
The EPA just made life easier for farmers and pesticide makers by saying cinnamaldehyde (a cinnamon-smelling ingredient) doesn’t need a strict residue limit when used in pesticides—up to 100 parts per million. This rule kicks in on June 26, 2026, saving time and money by cutting red tape. If anyone wants to object, they have until August 25, 2026, to speak up.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
100 ppm Limit Replaces Tolerance Requirement
If you make or use pesticides or grow food, EPA now exempts cinnamaldehyde (CAS No. 104-55-2) from the usual residue tolerance requirement when it is used as a preservative/stabilizer, as long as the final pesticide formulation contains not more than 100 parts per million (ppm). The rule is effective June 26, 2026; EPA says it will not register any pesticide formulation for food use that exceeds 100 ppm and an analytical enforcement method is not required for residues.
EPA Finds Use Safe at Proposed Levels
EPA evaluated health data and concluded cinnamaldehyde used as an inert preservative/stabilizer at the permitted levels is not expected to pose acute, chronic, or cancer risks. EPA estimated chronic exposure uses about 1% of the chronic population-adjusted dose (cPAD) for the U.S. population and about 2% for children 1–2 years old, and aggregate margins of exposure (MOE) are 12,658 for adults and 3,154 for children—well above EPA’s MOE level of concern of 100.

The EPA is rolling out the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) to check for new, sneaky chemicals in public drinking water. Big water systems serving 3,300+ people and some smaller ones will test for 30 different contaminants, including certain PFAS and pesticides, to keep our water safe. Comments and feedback are open until late August 2026, and the EPA will host fun online meetings to chat about the plan!
