EWG’s 2019 Shopper’s Guide to Pesticides in Produce™

Over Half of Samples of Kale Tainted With Possible Cancer-Causing Chemical

WEDNESDAY, MARCH 20, 2019

Nearly 70 percent of the produce sold in the U.S. comes with pesticide residues, according to EWG’s analysis of test data from the Department of Agriculture for our 2019 Shopper’s Guide to Pesticides in Produce™.

Kale

The most surprising news from the USDA tests reveals that the popular health food kale is among the most contaminated fruits and vegetables. More than 92 percent of kale samples had two or more pesticide residues detected, and a single sample could contain up to 18 different residues. The most frequently detected pesticide, found on nearly 60 percent of kale samples, was Dacthal, or DCPA – classified by the Environmental Protection Agency since 1995 as a possible human carcinogen, and prohibited for use in Europe since 2009.

Overall, the USDA found 225 different pesticides and pesticide breakdown products on popular fruits and vegetables Americans eat every day. Before testing, all produce was washed and peeled, just as people would prepare food for themselves, which shows that simple washing does not remove all pesticides.

The USDA had not tested kale for almost a decade. But even as its popularity as a food rich in vitamins and antioxidants has soared, the level and number of pesticide residues found on kale has increased significantly. EWG’s analysis places kale third on this year’s Dirty Dozen™, our annual ranking of the fruits and vegetables with the most pesticides.

EWG’s Dirty Dozen for 2019

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

 

Each of these foods tested positive for a number of different pesticide residues and contained higher concentrations of pesticides than other produce. Key findings:

  • More than 90 percent of samples of strawberries, apples, cherries, spinach, nectarines, and kale tested positive for residues of two or more pesticides.
  • Multiple samples of kale showed 18 different pesticides.
  • Kale and spinach samples had, on average, 1.1 to 1.8 times as much pesticide residue by weight than any other crop.

Different fruits and vegetables can have vastly different levels and numbers of pesticides detected on the crop. All research agrees on the health benefits of a diet that includes fruits and vegetables, and eating fresh produce – organic or conventional, as budget allows – is essential for health.

The Shopper’s Guide is a resource designed to help you reduce your pesticide exposures as much as possible by indicating which produce to buy organic, and which conventional products are low in pesticide residue. That’s why we also analyzed the USDA data to produce the Clean Fifteen™, our list of the fruits and vegetables that have few, if any, detected pesticide residues.

EWG’s Clean Fifteen for 2019

  1. Avocados
  2. Sweet corn
  3. Pineapples
  4. Frozen sweet peas
  5. Onions
  6. Papayas
  7. Eggplants
  8. Asparagus
  9. Kiwis
  10. Cabbages
  11. Cauliflower
  12. Cantaloupes
  13. Broccoli
  14. Mushrooms
  15. Honeydew melons

 

Relatively few pesticides were detected on these foods, and tests found low total concentrations of pesticide residues. Key findings:

  • Avocados and sweet corn were the cleanest. Less than 1 percent of samples showed any detectable pesticides.
  • More than 70 percent of Clean Fifteen fruit and vegetable samples had no pesticide residues.
  • With the exception of cabbage, all other produce on the Clean Fifteen tested positive for less than four pesticides.
  • Multiple pesticide residues are extremely rare on Clean Fifteen vegetables. Only 6 percent of Clean Fifteen fruit and vegetable samples had two or more pesticides.
