This vegetable is packed with nutrients, making it a staple for healthy eating. But federal data show that this conventionally grown vegetable has more pesticide residues by weight than all other produce tested, with three-fourths of samples tested contaminated with a neurotoxic bug killer banned from use on food crops in Europe. Which vegetable is it?
The answer is spinach.
The latest tests by the Department of Agriculture, in 2015 and 2016, showed a sharp increase in pesticide residues on non-organic spinach since the crop was last tested in 2008 and 2009. Based on the USDA tests, EWG’s Shopper’s Guide to Pesticides in Produce™ ranks spinach second on the Dirty Dozen™ list of fruits and vegetables with the most pesticides – a significant jump from its previous rank of eighth.
