Evidence continues to show that paraquat does indeed directly lead to a higher likelihood of developing Parkinson's Disease. The first research was made public in 2009 in the American Journal of Epidemiology. In 2011, the National Institute of Health published that farmers who used paraquat were 250 percent more likely to develop the disease. And more recently, in 2017, the Unified Parkinson's Advocacy Council urged the EPA to ban paraquat. While the risk is low for residential use, there are clear connections for many agricultural occupations including farmers, applicators, mixers, and tank fillers. There is also a high risk for people and families living in and around farming communities.
