x Strawberries, spinach and kale are the top offenders on this year’s Dirty Dozen list, an annual ranking of the most pesticideladen produce by the nonprofit advocacy organization Environmental Working Group. Also among the top 12: collard and mustard greens, nectarines, apples, grapes, bell and hot peppers, cherries, peaches, pears, celery and tomatoes. Kale, collard and mustard greens, hot peppers and bell peppers had the most pesticides, according to the group. A single sample of kale, collard and mustard greens had up to 21 different pesticides. The group recommends consuming organic versions of these fruits and vegetables if possible, to limit exposure to pesticides. Want produce with the least amount of pesticides? Avocados, sweet corn and pineapple topped the group’s “Clean Fifteen.” Onions, papaya, frozen sweet peas, asparagus, honeydew melon, kiwi, cabbage, mushrooms, cantaloupe, mangoes, watermelon and sweet potatoes were also on the “clean” list. Nearly 70% of the fruits and veggies on the list had no detectable pesticide residues, while just under 5% had residues of two or more pesticides, the report said.
