Seven Senators Join Congressional Push to Prohibit Toxic Herbicide
Seven US senators issued an urgent appeal to the Environmental Protection Agency on October 31, 2024, demanding a nationwide ban on Paraquat, a controversial herbicide linked to Parkinson’s disease and various cancers. The senators’ letter to EPA Administrator Michael Regan follows earlier pressure from 47 Members of Congress, who made similar demands in early October. The EPA plans to release its final assessment of Paraquat’s health risks by mid-January 2025, while thousands of American users who have Parkinson’s pursue legal action against Chinese manufacturer Syngenta.
5 Key Points
- Seven senators and 47 Congress members demand that the EPA ban paraquat herbicide.
- Studies link Paraquat to a 64% higher risk of developing Parkinson’s disease.
- More than 70 countries, including China and Brazil, have banned the chemical.
- Manufacturer Syngenta faces lawsuits from thousands of Parkinson’s patients.
- EPA will release the final assessment of paraquat health risks in January 2025.
Congressional Coalition Demands Federal Action
Cory Booker thrust Paraquat into the national spotlight with his October 31 directive to EPA Administrator Michael Regan, marking a decisive shift in federal pesticide regulation. The New Jersey senator’s letter, backed by six colleagues, amplifies an earlier demand from 47 House representatives who petitioned for the herbicide’s immediate prohibition. Their evidence draws from extensive epidemiological research revealing a 64% elevated Parkinson’s risk among agricultural workers exposed to Paraquat. The EPA’s current position—denying a “clear link” between the herbicide and neurological damage—faces unprecedented scrutiny from both chambers of Congress. Legislators point to documented cases of thyroid cancer and non-Hodgkin’s Lymphoma in farming communities, compelling the agency to accelerate its review process ahead of the January 2025 deadline.
Medical Research Contradicts Corporate Claims
University of Rochester neurologist Ray Dorsey documented Paraquat’s six-decade trail of neurological devastation through comprehensive clinical studies and laboratory analysis. “When paraquat is banned, more lives will be spared the consequences of Parkinson’s,” Dorsey declared, referencing a compilation of human trials and laboratory studies that trace the herbicide’s impact on brain chemistry. Despite public denials, Syngenta harbored internal documents exposing their awareness of Paraquat’s effect on dopamine production and neural pathway disruption. The Guardian’s investigation revealed the Chinese manufacturer’s systematic campaign to manipulate scientific literature through targeted research funding and selective data publication. Internal memos obtained through legal discovery detail corporate strategies designed to challenge independent studies linking paraquat exposure to neurological disorders, while company scientists privately acknowledged the potential health risks.
American Agriculture Lags Behind Global Standards
China—home to Syngenta’s corporate headquarters—joins Brazil, Turkey, and the European Union among 70 nations prohibiting paraquat use in agricultural operations. The senators’ petition documents the herbicide’s connection to thyroid cancer, non-Hodgkin’s Lymphoma, and severe reproductive disorders affecting both agricultural workers and rural residents. Rural communities bear the heaviest burden, with agricultural zones reporting elevated rates of leukemia in children born to mothers exposed during pregnancy. These findings mirror patterns documented across international jurisdictions that enacted bans, particularly in European nations where longitudinal studies tracked health outcomes before and after prohibition. Brazilian agricultural data demonstrates successful transitions to alternative weed control methods, challenging Syngenta’s claims about Paraquat’s irreplaceability in modern farming.
Litigation Mounts as Regulatory Deadline Looms
Parkinson’s patients across America filed a mass tort against Syngenta, presenting evidence of the manufacturer’s deliberate concealment of neurological risks spanning three decades. Their lawsuit details the company’s systematic suppression of scientific data suggesting links between paraquat exposure and brain damage, including internal research papers never shared with regulatory agencies. The EPA’s forthcoming January 2025 assessment carries implications beyond immediate agricultural practices, potentially establishing new precedents for chemical safety evaluation and corporate liability. Legal documents reveal Syngenta executives discussed strategies to minimize public awareness of Paraquat’s health risks while maintaining market share in countries lacking stringent environmental protections. The confluence of congressional pressure, international precedent, and mounting litigation places unprecedented pressure on federal regulators to align American agricultural safety standards with global protocols.
