EPA Finalizes Guidance to Waive Toxicity Tests on Animal Skin

On January 19, the U.S. Environmental Protection Agency (EPA) published final guidance that will allow researchers to forego testing chemicals on animal skin in certain circumstances. The “Final Guidance for Waiving Acute Dermal Toxicity Tests for Pesticide Single-Active Ingredient and Supporting Retrospective Analysis” allows for data waivers for acute dermal studies for single active ingredients used to develop end-use products. The document includes a policy statement to waive all acute lethality dermal studies for single active ingredients.
