Forty-seven Democratic members of Congress have asked Environmental Protection Agency Administrator Michael Regan to ban the use of the herbicide paraquat. The lawmakers, led by Texas Congressman Greg Casar, told Regan the chemical is particularly dangerous for farmworkers. The EPA says it has yet to find a scientific link between the use of the herbicide and Parkinson’s disease. At the end of January 2024, EPA released a report on the ongoing review of paraquat. Due to the significant human health and environmental concerns associated with paraquat, roughly 70 countries have banned or discontinued the use of the chemical, including China, Brazil, the European Union, and Canada. Findings from researchers at UCLA found that paraquat sprayed within 500 meters of where people live and work can more than double a person’s odds of developing Parkinson’s disease.
