Glyphosate at the Crossroads: Supreme Court, Farm Bill, and the MAHA-EPA Conflict

Supreme Court Hearing and Farm-Bill Liability Clause
On April 28, 2026 the Supreme Court heard arguments on whether the Federal Insecticide, Fungicide and Rodenticide Act preempts state lawsuits claiming Bayer’s glyphosate-based herbicide Roundup caused cancer. At the same time the House farm-bill advanced a labeling provision that MAHA activists label a “liability shield” for pesticide manufacturers.
Background and Executive Action
The IARC classified glyphosate “probably carcinogenic” in 2015, while the EPA says it is safe and requires no cancer warnings. President Trump signed an executive order invoking the Defense Production Act to boost glyphosate production, a step backed by EPA Administrator Lee Zeldin and opposed by Health Secretary Robert F. Kennedy Jr.
Official EPA Statements and Policy Moves
The EPA told NPR it is “committed to transparency and science” and takes MAHA concerns “seriously.” Its amicus brief argued that preemption would avoid a patchwork of state labeling rules. EPA rolled back PFAS drinking-water standards, weakened mercury protections, and added microplastics and pharmaceuticals to the Contaminant Candidate List without guaranteeing regulation. A 2018 jury awarded $290 million to a Roundup user for alleged cancer, and Administrator Zeldin called the rollbacks “deregulation with zeal.”
MAHA Criticism and Opposition
MAHA activists call the administration’s moves “PR stunts” that betray health promises. Vani Hari warned officials they “cannot claim to care about health while protecting poison.” Ryerson called the executive order and Supreme Court defense of Bayer “inexcusable,” and Murphy described the shift as “appalling.”
Conflicting Reports and Gaps
The WHO’s 2015 classification of glyphosate as “probably carcinogenic” conflicts with the EPA’s view that the chemical is safe. MAHA calls the farm-bill labeling clause a liability shield, while G.T. Thompson says it simply ensures labeling follows scientific standards. Adding microplastics to the Contaminant Candidate List signals intent but offers no regulatory timeline, a gap noted by professor Chris Frey.
Verbatim Quotes
- “You cannot claim to care about health while protecting poison. You cannot tell Americans to eat real food while protecting the cancer-causing chemicals sprayed on it,” — Vani Hari, wellness influencer
- “The combination of the executive order and going to bat for Bayer at the Supreme Court are really inexcusable,” — Kelly Ryerson, MAHA activist
- “When you don’t have anything good to say, some advise to just not say anything at all.” — Lee Zeldin, EPA Administrator
- “I don’t have to listen to this BS!” — Rosa DeLauro, Representative
What’s Next
The Supreme Court is expected to issue its decision later in 2026, determining whether federal preemption shields Bayer from state cancer claims. The farm-bill’s labeling clause faces a House vote before the November midterms, a contest that could reshape Republican outreach to health-focused voters. Ongoing lawsuits and EPA research cuts suggest further legal and scientific disputes over glyphosate will persist.
