Environmental Working Group's 2012 DirtyDozen List The EWG's Shopper's Guide is not built on a complex assessment of pesticide risks but instead reflects the overall pesticide loads of common fruits and vegetables. This approach best captures the uncertainties of the risks of pesticide exposure. Since researchers are constantly developing new insights into how pesticides act on living organisms, no one can say that concentrations of pesticides assumed today to be safe are, in fact, harmless. The Shopper's Guide aims to give consumers confidence that by following EWG's advice to buy the following foods organic, they can buy foods with consistently lower overall levels of pesticide contamination. EWG recommends the following foods should be purchased organic... In general, tree fruits, berries, leafy greens dominate the list... 1. Apples 2. Celery 3. Sweet bell peppers 4. Peaches 5. Strawberries 6. Nectarines 7, Grapes 8, Spinach 9. Lettuce 10. Cucumbers 11. Blueberries 12. Potatoes Plus + Green beans + Kale/Greens Available at our market when in season.   Read more at http://www.ewg.org/release/ewg-releases-2012-shopper-s-guide-pesticides-produce
