Apples, celery and strawberries are at the top of the latest "Dirty Dozen" list compiled by the Environmental Working Group, while onions, sweet corn and pineapples are among the "Clean 15" fruits and vegetables the EWG says are least likely to carry pesticide residue.
In releasing the 2011 Shopper's Guide to Pesticides in Produce, its seventh edition, the advocacy group emphasized that the health benefits of a diet abundant with fruits and vegetables outweigh the risk of pesticide exposure.
Below is a list of the Dirty Dozen and the Clean 15:
Dirty Dozen: Apples, celery, strawberries, peaches, spinach, imported nectarines, imported grades, sweet bell peppers, potatoes, domestic blueberries, lettuce, kale/collard greens.
Clean 15: Onions, sweet corn, pineapples, avocado, asparagus, sweet peas, mangoes, eggplant, domestic cantaloupe, kiwi, cabbage, watermelon, sweet potatoes, grapefruit, mushrooms.
