Key Findings of the 2017 Dirty Dozen Report

• More than 98 percent of samples of strawberries, spinach, peaches, nectarines, cherries and apples tested positive for residue of at least one pesticide.

• A single sample of strawberries showed 20 different pesticides.

• Spinach samples had, on average, twice as much pesticide residue by weight than any other crop.

• Avocados and sweet corn were the cleanest: only 1 percent of samples showed any detectable pesticides. (Note: GMO Corn is sold in some areas, choose organic or know your farmer to avoid that.)

• More than 80 percent of pineapples, papayas, asparagus, onions and cabbage had no pesticide residues. (Note: Some papayas are GMOs. Choose organic to avoid that.)

• No single fruit sample from the Clean Fifteen tested positive for more than four types of pesticides.
