There was a study earlier this summer that found that seven out of eight bags of kale sampled from U.S. grocery stores contains high levels of PFAS. Yes, even in organic kale - in fact, the levels were even higher in the organic produce.

"The group tested kale because it 'wanted to look at an archetypal healthy vegetable' that was high in protein, which PFAS compounds bind to. The source of the contamination is unclear, but Verkerk said he suspected tainted water was probably to blame, though it was also possible the kale was grown in fields where sludge was spread."
