Strawberries remain at the top of the Environmental Working Group’s Dirty Dozen list, with spinach jumping to second place in the annual ranking of conventionally grown produce with the most pesticide residues.
The EWG's analysis of tests by the U.S. Department of Agriculture found that nearly 70 percent of samples of 48 types of conventional produce were contaminated with residues of one or more pesticides. USDA researchers found a total of 178 different pesticides and pesticide breakdown products on the thousands of produce samples they analyzed. The pesticide residues remained on fruits and vegetables even after they were washed and, in some cases, peeled.
"If you don't want to feed your family food contaminated with pesticides, the EWG Shopper's Guide helps you make smart choices, whether you're buying conventional or organic produce," said Sonya Lunder, an EWG senior analyst. "Eating plenty of fruits and vegetables is essential no matter how they're grown, but for the items with the heaviest pesticide loads, we urge shoppers to buy organic.”
