Kale and the Dirty Dozen

March 20, 2019 — While it may still be considered a super food, kale took third place on this year’s “Dirty Dozen” list of fruits and vegetables with the most pesticide residue. Once again, strawberries and spinach took first and second, as they did on last year’s list.

The Environmental Working Group (EWG), a nonprofit organization focused on human health and the environment, has produced the report annually since 2004.

The EWG researchers analyzed test data from the U.S. Department of Agriculture for the report, and kale had not been tested in more than 10 years, says Nneka Leiba, MPH, director of healthy living science at EWG and a co-author of the report. “The percent of [kale] samples with residue increased from 76% to 98%,” she says, citing the difference between the testing in 2007 and in 2017, the data used for this year’s report. “The average number of residues on a single sample increased from two to more than five.”

Leiba stresses that the report should not discourage people from eating fruits and vegetables, although she does suggest people choose organic produce when possible as even washing produce does not remove all pesticides.

Other experts who viewed the report say the amount of pesticides found is not high enough to be a health hazard.
