Each year, we get a snapshot of pesticide use in America when the ‘Dirty Dozen’ and ‘Clean Fifteen’ lists from the Environmental Working Group come out. And while it’s much of the same ‘ole, same ‘ole in terms of which foods made what lists for 2019, there is one notable takeaway and it’s about…kale. The USDA, which remarkably had not looked at this leafy green in nearly a decade despite its growing popularity among the health-conscious (Helllloooo?), found it to be…dirty. Real dirty. Third dirtiest when it comes to pesticide contamination, right behind strawberries and spinach. Nutritionists are blowing this off, but the findings may inspire you to opt out (or at the very least, go organic): Over 92% of kale samples contained two or more pesticide residues. Some had up to 18. Even scarier: the most frequently detected pesticide, found on nearly 60% of the samples, was DCPA, which has long been classified as a possible human carcinogen.
