2017 Dirty Dozen

Are You Eating the Most Pesticide-Laden Produce?

Environmental Working Group released it’s 2017 Dirty Dozen list and it serves as a solid reminder that we still have a lot of work to do when it comes to cleaning up the food system. This year, the annual report found that almost 70 percent of 48 non-organic samples tested positive for at least one pesticide. (In many cases, the numbers were much higher.) And get this: A single strawberry sample harbored 20 different pesticide residues.

And while spinach nutrition is loaded with calcium and vitamins, there’s one reason to always try to choose organic. Researchers found DDT, a neurotoxic insecticide banned in the U.S., in an alarming number of samples.

A “Clean 15” list is also included in the report, identifying the non-organic produce least likely to be contaminated with pesticide levels. I advise choosing and growing organic as often as possible, but if you’re on a budget or your selection is limited, these lists help you focus your attention on avoiding the most contaminated fruits and veggies.


Key Findings of the 2017 Dirty Dozen Report

  • More than 98 percent of samples of strawberries, spinach, peaches, nectarines, cherries and apples tested positive for residue of at least one pesticide.
  • A single sample of strawberries showed 20 different pesticides.
  • Spinach samples had, on average, twice as much pesticide residue by weight than any other crop.
  • Avocados and sweet corn were the cleanest: only 1 percent of samples showed any detectable pesticides.
  • More than 80 percent of pineapples, papayas, asparagus, onions and cabbage had no pesticide residues. (Note: Some papayas are GMOs. Choose organic to avoid that.)
  • No single fruit sample from the Clean Fifteen tested positive for more than four types of pesticides.
