Clean 15 and Dirty dozen

The Clean 15 and Dirty Dozen are two lists published annually by the Environmental Working Group (EWG) to help consumers make informed choices about produce and pesticide exposure.

The Dirty Dozen refers to the 12 types of fruits and vegetables that tend to have the highest levels of pesticide residues when grown conventionally. These include popular foods like strawberries, spinach, apples, and grapes. For these items, buying organic is often recommended when possible to reduce pesticide intake.
