Dirty Dozen
The environmental working group (EWG) tests fruits and vegetables for pesticide residues.
The Dirty Dozen™ is a trademark term used to define the twelve crops that farmers typically use the most pesticides on, versus, the Clean 15™ which is also a trademark term to describe the fifteen fruits and vegetables that have the lowest amount of pesticide residue.
The 501(c)(3) nonprofit Environmental Working Group owns the trademarks to both these terms and produces these two food lists annually as part of the EWG’s Shopper’s Guide to Pesticides in Produce™ awareness campaign. Here is a list for the year 2024. Hope it helps you in your next grocery shopping trip.
