Vermont becomes first US state to ban paraquat herbicide over Parkinson's fears

Vermont became the first US state to ban the weedkilling pesticide paraquat. Lawmakers cited research indicating paraquat exposure substantially increases the risk of Parkinson’s disease, an incurable brain ailment. Governor Phil Scott signed the legislation, which takes effect on 1 November. The law allows state regulators to issue special permits for paraquat use on fruit-producing tree orchards, berries, and other small fruit crops until 31 December 2030. The law requires annual data reporting on any paraquat use in the state and includes a state-funded study on recommendations for alternatives for farmers. Some lawmakers raised concerns about competitiveness and the need for more research, while others said the scientific evidence is established and the risks of keeping paraquat outweigh the risks of banning it.

"Vermont is the first US state to ban the weedkilling pesticide paraquat, backed by lawmakers who cited concerns about research showing the chemical substantially increases the risk of the incurable brain ailment known as Parkinson's disease. Phil Scott, the governor, signed the legislation on Tuesday. The new law takes effect on 1 November, though it contains a provision allowing state regulators to issue special permits for paraquat use on fruit-producing tree orchards, berries and other small fruit crops up until 31 December 2030."

"The law also calls for annual data reporting on any use of paraquat in the state, and a state-funded study on recommendations for alternatives to the use of paraquat for farmers. Some lawmakers expressed concern that a ban will hurt the competitiveness of Vermont farmers if the chemical is still allowed for use in other states, and said more research is needed to fully prove a link between paraquat and Parkinson's. But others said the scientific research was well established and the risks of not banning the chemical outweigh the risks of keeping it on the market."

"Early versions of the law pointed to multiple studies by the National Institutes of Health have demonstrated that paraquat exposure substantially increases the risk of Parkinson's disease in those exposed to the herbicide. Lawmakers also noted that other NIH studies have linked paraquat to non-Hodgkin lymphoma and childhood leukemia. There are so many factors that are pointing to the correlation between paraquat use and Parkinson's, Michelle Bos-Lun, a state representative, said in a 13 May House committee hearing about the bill."

"We have to do something to phase this out. Our job is to support farmers and to support all Vermonters. My belief is that paraquat is causing harm to both. Ray Dorsey, a neurologist who directs research into environmental causes of brain diseases at Atria Health and Research Institute, said Vermont's action was another step toward preventing this large"
