What Makes the Dirty Dozen So Darn Dirty?

The Environmental Working Group (EWG) just released its 2011 list of the 'Dirty Dozen' fruits and vegetables.

The list also included spinach, imported nectarines, imported grapes, sweet bell peppers, potatoes, domestic blueberries, lettuce, and kale/collard greens.
