Dear Green Mama: What is the dirty dozen?
Dear D.D.: The dirty dozen refers to the fruits and vegetables that are commonly found to have the highest levels of pesticide residue. A note of interest, most fruits and vegetables contain pesticide residues according to the USDA whom detected pesticides in 7 out of every 10 samples analyzed in 2008. My favorite resource for tracking the dirty dozen is from the consumer watch-dogs and researchers at the Environmental Working Group’s Food News. I like the practical nature of this list which looks both at the most contaminated produce and the cleaner alternatives.
The food in their samples are washed and/or peeled (whatever is typical for that food) before being tested. Thus, you can not assume that peeling a food will improve its ranking—many pesticides are absorbed by the plants just as the water and nutrients from the soil are taken up by the plant. You can learn more about the EWG protocol for their rankings and other tips for reducing pesticide exposure on their website.

- Berries: including strawberries, blueberries, cherries, red raspberries
- Sweet Bell Peppers
- Greens: including spinach, kale, collard greens, and lettuce
