The Most Contaminated & Most Clean Foods in 2024

I started following the Environmental Working Groups research a couple years ago. Each year they release their analysis of the most contaminated foods, dubbed The Dirty Dozen™ as well as The Clean Fifteen, produce with the lowest numbers of pesticides.


In the US alone, over 1 billion pounds of pesticides are used, ranking us #1 in the world ahead of Brazil and China.




The Top 12 Most Toxic Foods in The US in 2024:


  1. Strawberries

  2. Spinach

  3. Kale, Collared & Mustard Greens

  4. Grapes

  5. Peaches

  6. Pears

  7. Nectarines

  8. Apples

  9. Bell & Hot Peppers

  10. Cherries

  11. Blueberries

  12. Green beans


Study Highlights:

  • A total of 209 pesticides were found on Dirty Dozen items.

  • Across all 12 items, 95 percent of samples had pesticides.

  • Over 90 percent of samples of strawberries, apples, cherries, spinach, nectarines and grapes tested positive for residues of two or more pesticides. 

  • More than 50 pesticides were detected on samples from each item on the Dirty Dozen, except cherries.

  • The most pesticides were found on kale, collard and mustard greens, with 103 individual chemicals found across the items in the category.

  • Hot peppers and bell peppers were next, with 101.

  • All of the produce on the Dirty Dozen had at least one sample with at least 13 pesticides — and some had as many as 23.

  • The neurotoxic organophosphate insecticide acephate, prohibited from use on green beans in 2011, was detected on six percent of that crop’s samples.

  • Just over 10 percent of Clean Fifteen fruit and vegetable samples had residues of two or more pesticides.
