EWG has posted it’s 2010 Shopper’s Guide to Pesticides and it is really worth a look.  They have a quick and easy to use guide that you can print out OR you can download an app for your iPhone. But the long of the short of it is:

Dirty Dozen (Buy these organic – have highest pesticide levels – #1 has highest):

1. Celery
2. Peaches
3. Strawberries
4. Apples
5. Blueberries
6. Nectarines
7. Bell Peppers
8. Spinach
9. Cherries
10. Kale/Collard Greens
11. Potatoes
12. Grapes (imported)

Clean 15 (lowest pesticides – #1 is the best)

1. Onions
2. Avocade
3. Sweet Corn
4. Pineapple
5. Mangoes
6. Sweet Peas
7. Asparagus
8. Kiwi
9. Cabbage
10. Eggplant
11. Cantaloupe
12. Watermelon
13. Grapefruit
14. Sweet Potato
15. Honeydew Melon

EWG says that people who eat 5 fruits and veggies from the Dirty Dozen list consume an average of 10 pesticides a day. Those who eat from the Clean 15 list  ingest fewer than 2 pesticides daily.

And I think it’s worthy to note that this data was compiled based on produce “tested as it is typically eaten (meaning washed, rinsed or peeld, depending on the type of produce). Rinsing reduces but does not eliminate pesticides. Peeling helps, but valuable nutrients often go down the drain with the skin. The best approach: eat a varied diet, rinse all produce and buy organic when possible.”
