How clean is the produce you’re buying? You might be surprised. Here’s just how dirty your favorite fruits and veggies actually are.

Beware kale lovers, the leafy green has just joined an exclusive list that no vegetable wants to be on.

Kale was named as one of the 12 fruits and vegetables with the most pesticide residues. 

For the last 15 years, the nonprofit, non-partisan, Environmental Working Group (EWG) has ranked produce on pesticide contamination levels. Specifically, after that produce has been washed and peeled. 

This year’s dirty dozen are:

  1. Strawberries
  2. Spinach
  3. Kale
  4. Nectarines
  5. Apples
  6. Grapes
  7. Peaches
  8. Cherries
  9. Pears 
  10. Tomatoes
  11. Celery
  12. Potatoes

In contrast, the produce with the least amount of pesticide residues make up the “clean fifteen.” The top three on that list are:

  1. Avocados
  2. Sweet corn
  3. Pineapples

Pesticides are any chemicals that are used to kill bugs, other plants, or rodents that harm produce.

The rankings are based off more than 40,000 fruit and vegetable samples, tested by the Food and Drug Administration, and the U.S. Department of Agriculture. 

EWG recommends buying organic versions of the produce on the dirty dozen list whenever possible, and if organic isn’t available, they say don’t skip produce because the health benefits of eating it still outweighs the risks of pesticide exposure.
