The EWG has expanded the Dirty Dozen with a Plus category to highlight two crops -- green beans and leafy greens, meaning, kale and collard greens - that did not meet traditional Dirty Dozen criteria but were commonly contaminated with highly toxic organophosphate insecticides. These insecticides are toxic to the nervous system and have been largely removed from agriculture over the past decade. But they are not banned and still show up on some food crops.

*Commodity crop corn used for animal feed and biofuels is almost all produced with genetically modified (GMO) seeds, as is some sweet corn sold for human consumption. Since GMO sweet corn is not labeled as such in US stores, EWG advises those who have concerns about GMOs to buy organic sweet corn.
