The Dirty Dozen™ list for 2015 includes: apples, celery, cherry tomatoes, cucumbers, grapes, nectarines, peaches, potatoes, snap peas, spinach, strawberries, sweet bell peppers. They also add collard greens & kale, and hot peppers because they contain pesticides that are particularly alarming in terms of negative health effects.
They also release an annual list called "The Clean 15™", which are found to have little or no traces of pesticides. If you have to buy some conventionally grown produce, these are the safest choices: asparagus, avocado, cabbage, cantaloupe, cauliflower, corn, eggplant, grapefruit, kiwi, mangos, onions, papayas, pineapples, frozen sweet peas, and sweet potatoes.
We only use organic corn even though it is on The Clean 15™ list, because 88% of the corn grown in the U.S. (as of 2011) is genetically modified, which you can find out about in the next post.
