Strawberries Top Dirty Dozen List for Pesticide Contamination; Avocados Cleanest Produce

Strawberries topped the "Dirty Dozen" list of most pesticide-contaminated produce, followed by spinach and leafy greens like kale and collards.

Grapes, peaches, pears, nectarines, apples, bell peppers, cherries, blueberries, and green beans also made the "Dirty Dozen" list.

Avocados were found to have the lowest levels of pesticide residues, topping the "Clean Fifteen" list.

Sweet corn, pineapple, onions, papaya, frozen peas, eggplant, asparagus, and melons were also on the "Clean Fifteen" list.

The Environmental Working Group analyzes USDA and FDA data on pesticide levels in produce to create its annual "Dirty Dozen" and "Clean Fifteen" lists.
