Carsten Prasse assistant professor, Whiting School "We do see minute traces of pesticides in the kale, but the levels we found are so much lower than the amounts that would be concerning." Prasse's team screened kale from six small farms in Maryland—two urban farms in Baltimore and four rural farms outside the city. The farms used either conventional pesticides or certified organic ones. The team found six pesticides and related compounds in the kale, including traces of pesticides not used by the farms. Although the researchers were focused on pesticides, they also wanted to know what else could be in the kale.
