Exposure to paraquat has been linked Parkinson’s, non-Hodgkin’s Lymphoma, thyroid cancer and other thyroid issues. Paraquat is a toxic herbicide (weedkiller) that can be fatal if even a tiny amount is swallowed. Serious harm can also occur to the eyes, skin and body with exposure to the spray or mist of paraquat. The EPA does not permit the use of paraquat on golf courses or residential areas yet allows it to be used for fields and orchards where both human and animal food is grown. To date, over 50 countries no longer permit the use of paraquat, including China, Brazil, the European Union, Chile, Taiwan, the United Kingdom and Turkey. Additionally, paraquat is no longer registered for use in Canada.
A 2019 meta-analysis of 13 studies found a 64 percent increase in the likelihood of developing Parkinson’s disease from paraquat exposure.[1] A 2024 study from researchers at UCLA showed paraquat sprayed within 500 meters, or about 1,640 feet, of where people lived and worked could more than double a person’s odds of developing Parkinson’s.[2] Additionally, Parkinson’s Disease incidence rates are higher in certain geographic areas of the U.S., including Central Pennsylvania.[3]
Dozens of other countries have found safer alternatives to paraquat, and we think it’s time Pennsylvania does the same. While federal pesticide law (FIFRA) sets a minimum floor, we believe it is time to set the ceiling for our Commonwealth. We must work to decrease the occupational and environmental risks for both agricultural workers and the citizens who live near the fields and orchards where paraquat is sprayed.
We hope you will join us in support of this legislation.
