The bill increases protection from potential multigenerational pesticide harms and transparency of EPA action, but does so at the cost of higher testing burdens, likely price impacts and delays, and added strain on regulatory resources.
Consumers and farmworkers would face lower exposure to potentially harmful pesticide residues because tolerances could be tightened based on multigenerational toxicity data.
Regulators would gain better scientific information about long‑term and multigenerational reproductive effects through increased testing requirements, enabling safer, more evidence‑based tolerance decisions.
Congress (and taxpayers) would receive a transparency report within two years listing which tolerances were reviewed or changed, improving oversight of EPA pesticide decisions.
Manufacturers would face higher costs and longer timelines from four‑generation study requirements, which could delay approvals and keep some pest control products off the market.
Higher compliance and testing costs are likely to be passed on to buyers, increasing prices for agricultural products and pest control goods for consumers and farmers.
Requiring existing determinations to be re‑evaluated within 180 days could strain EPA resources and divert staff from other regulatory work, creating agency backlog or slower processing elsewhere.
Based on analysis of 2 sections of legislative text.
Requires EPA to base pesticide tolerance and exemption actions on four-generation reproductive toxicity studies and to review past determinations within 180 days.
Official title: To amend the Federal Food, Drug, and Cosmetic Act to direct the Administrator of the Environmental Protection Agency to rely on certain data with respect to a toxicity determination related to a pesticide chemical residue, and for other purposes.
Introduced August 24, 2026 by Nancy Mace · Last progress August 24, 2026
Requires the EPA to use data from multigenerational reproductive toxicity studies (at least four generations) when establishing, modifying, revoking, or continuing pesticide tolerances or exemptions. Directs the Administrator to review past tolerance determinations within 180 days to see if they meet the new data requirement and to report to Congress within two years identifying any determinations reviewed, updated, or changed because of this rule. The change amends Federal food safety law to make a specific, stricter data standard the basis for pesticide tolerance decisions and adds short review and reporting deadlines for the EPA Administrator.
