2019 Dirty Dozen and Clean 15 Lists

Every year, the Environmental Working Group releases its Shopper’s Guide to Pesticides in Produce, also known as the “Dirty Dozen.” Based on the U.S. Department of Agriculture’s Pesticide Data Report, these items represent produce found to have the most pesticide residue. The numbers are quite shocking!

Nearly 70 percent of samples were contaminated with residue from at least one of 178 pesticides (strawberries had as much as 20 pesticides!). These chemicals remained on fruits and vegetables even after they were washed and, in some cases, peeled.

While this list is updated every year, there are certain items that make it on this list frequently. When possible, buy organic or grow your own to reduce the amount of exposure you have to dangerous pesticides.

This year, the Environmental Work Group identified the following items as the Dirty Dozen:

  1. Strawberries

  2. Spinach

  3. Kale

  4. Nectarines

  5. Apples

  6. Grapes

  7. Peaches

  8. Cherries

  9. Pears

  10. Tomatoes

  11. Celery

  12. Potatoes
    + EWG’s Dirty Dozen Plus:

  13. Hot Peppers +

In addition to the Dirty Dozen, the Environmental Work Group also identifies produce with the least amount of pesticide residue, known as the “Clean 15”. The 2017 Clean 15 list includes:

  1. Avocados

  2. Sweet Corn*

  3. Pineapples

  4. Sweet Peas Frozen

  5. Onions

  6. Papayas*

* Per the EWG, a small amount of sweet corn, papaya and summer squash sold in the United States is produced from Genetically Engineered (GE) seed stock.

The University of Washington created an informative piece about pesticides in fruit and vegetables, detailing the effects of pesticides through consumption as well as exposure during use. It’s definitely worth the read and can be found here.

P.S. Organic produce is increasingly easier to find. Where do you shop for your organic produce?
