Environmental Working Group release the 2017 list of the Dirty Dozen (12 non-organic fruits and vegetables most contaminated with pesticides) and the Clean 15 (15 non-organic fruits and vegetables with the least amount of pesticides). Go to the Environmental Working Group website and download your copy today. How should you use this guide? For the Dirty Dozen fruits and vegetables - ALWAYS choose Organic, even if these items are the only Organic items you eat you can avoid 90% of your potential exposure to pesticides and herbicides. For the Clean 15 fruits and vegetables - choose organic if it is available to you and in your budget but if you don't get Organic, your pesticide exposure will be low.
