Leafy greens such as spinach and kale and perennial kid favorites such as strawberries and grapes held the highest levels of potentially harmful pesticide residues based on government tests, according to the 2026 Shopper's Guide to Pesticides in Produce. Nectarines, peaches, cherries, apples, blackberries, pears, potatoes and blueberries filled out this year's "Dirty Dozen" most pesticide-laden fruits and vegetables, according to the report released Tuesday by the Environmental Working Group, or EWG, a health advocacy organization. Spinach, which holds the top spot, had more pesticide residue by weight than any other type of produce and contained, on average, four or more different types of pesticides. Samples of every produce type averaged four or more pesticides, except for potatoes, which averaged two. Consuming produce with multiple pesticides is concerning, experts say, because exposure to mixtures of pesticides may accumulate and raise risk. Children are especially susceptible to contaminants such as pesticides, even while in the womb. Pesticide exposure during pregnancy may lead to an increased risk of birth defects, low birth weight and fetal death," according to the AAP. "Exposure in childhood has been linked to attention and learning problems, as well as cancer." For the first time, the report found over 60% of all Dirty Dozen samples contain pesticides that are also "forever chemicals" called PFAS.
