The Environmental Working Group put together two lists, “The Dirty Dozen” and “The Clean 15,” to help consumers know when they should buy organic and when it is unnecessary. These lists were compiled using data from the United States Department of Agriculture on the amount of pesticide residue found in non-organic fruits and vegetables after they had been washed. The fruits and vegetables on “The Dirty Dozen” list, when conventionally grown, tested positive for at least 47 different chemicals, with some testing positive for as many as 67. For produce on the “dirty” list, you should definitely go organic — unless you relish the idea of consuming a chemical cocktail. “The Dirty Dozen” list includes:
- celery
- peaches
- strawberries
- apples
- domestic blueberries
- nectarines
- sweet bell peppers
- spinach, kale and collard greens
- cherries
- potatoes
- imported grapes
- lettuce
All the produce on “The Clean 15” bore little to no traces of pesticides, and is safe to consume in non-organic form. This list includes:
- onions
- mango
- avocados
- sweet corn
- pineapples
- sweet peas
- asparagus
- kiwi
- cabbage
- eggplant
- cantaloupe
- watermelon
- grapefruit
- sweet potatoes
- sweet onions
What are some types
of produce more prone to sucking up pesticides than others? Richard Wiles, senior vice president of policy for the Environmental Working Group says, “If you eat something like a pineapple or sweet corn, they have a protection defense because of the outer layer of skin. Not the same for strawberries and berries.”
