In the recent piece, "Secret files suggest chemical giant feared weedkiller's link to Parkinson's disease," journalists Carey Gillam and Aliya Uteuova report on documents that show efforts to refute and downplay scientific research linking the chemical paraquat to Parkinson's. In this conversation, we discuss what they found, how the EPA has responded, and how this relates to the rapid rise in Parkinson's disease in the United States.

Carey Gillam is the author of Whitewash: The Story of a Weed Killer, Cancer and the Corruption of Science, managing editor of The New Lede, a journalism project of the Environmental Working Group, was a longtime National Correspondent for Reuters, and is contributor to The Guardian. Aliya Uteuova is a visual journalist who reports on environmental justice for The Guardian.
