How many pesticides are on the produce we eat – and what can we do about it every day? We spoke with Alexis Temkin, PhD, senior toxicologist at the Environmental Working Group (EWG), for an overview of EWG’s 2025 Shopper’s Guide to Pesticides in Produce. We unpacked everything from the “Clean Fifteen” and “Dirty Dozen” lists to the most common chemicals of concern, the impact of choosing organic vs. non-organic, and how to properly wash your fruits and vegetables to help reduce surface pesticide residue.
