According to a new report from the Environmental Working Group (EWG), these foods are the most likely to be contaminated with synthetic pesticide residue. The findings are part of the EWG’s 2017 “[Dirty Dozen” and “Clean Fifteen](https://www.ewg.org/foodnews/ "undefined"),” a list of the most and least pesticide-ridden foods. To compile the ranking, the EWG analyzed tests conducted by the U.S. Department of Agriculture and Food and Drug of more than 36,000 samples from 48 different types of conventionally grown produce. “Even low levels of pesticide exposure can be harmful to infants, babies and young children, so when possible, parents and caregivers should take steps to lower children’s exposures to pesticides while still feeding them diets rich in healthy fruits and vegetables,” said Dr. Philip Landrigan of the Mt. Sinai School of Medicine, in a [statement](http://www.ewg.org/foodnews2017/press.php "undefined"). For the second year in the row, the EWG found that strawberries were the most contaminated fruit. Just last year, the red berry knocked apples—which held the title of most contaminated for five years—from the top spot. Pesticide residue has increased in strawberries because of out-of-season demand. This year, the most contaminated strawberry had traces of 20 different pesticides. Also moving up on the list this year are spinach and nectarines. Spinach jumps from the eighth to the second most contaminated product. The USDA found spinach samples contained more residue by weight than all other produce tested, and 75 percent of samples contained residue of permethrin, an insecticide that is used to treat lice and repel mosquitos. In high doses, it can cause damage to the nervous system. So what conventionally grown produce is safe to purchase? Sweet corn, according to the EWG. Only 1 percent of samples of both sweet corn and avocados (last year’s top pick) had any detectable pesticides. Though you’re safe from pesticide residue because of the food’s protective exterior, it’s important to note that the EWG does warn that a small amount of sweet corn, as well as papaya and summer [squash](http://realsimple.com/health/www.realsimple.com/food-recipes/shopping-storing/food/common-types-winter-squash "undefined"), are produced from genetically modified seeds. (Buy organic if you’re trying to avoid altered produce.) The EWG lists, which started in 1993, have gained a reputation among many notable doctors and health organizations, including the American Academy of Pediatrics, for reducing pesticide exposure in diets. But the Dirty Dozen list has also attracted some [criticism](http://vitals.lifehacker.com/why-you-shouldnt-buy-organic-based-on-the-dirty-dozen-1689190822 "undefined") for focusing on quantity of pesticides rather than toxicity. According to Sonya Lunder, EWG senior analyst, the group has taken to highlighting crops, like hot peppers this year, as the “Dirty Dozen Plus.” These produce picks don’t meet the traditional criteria, but have been found to have residue of highly toxic pesticides on them. Additionally, some [critics](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3135239/ "undefined") have pointed out that the levels of pesticide residue found on the food in this list, though higher than other fruits and vegetables, are generally still well below EPA tolerance levels. However, the EWG stands behind their list and cautions consumers to pay attention to any substantial trace of synthetic pesticide. Lunder told RealSimple.com in an e-mail that in the past, the Environmental Protection Agency has “revoked tolerances” or changed legal limits or altogether banned certain insecticides thought to be safe after revising risk assessment. For example, last fall the tolerances for Chlorpyrifos, a pesticide once widely detected on fruits and vegetables, were revoked after it no longer met the EPA’s safety standards.
