After years of using Roundup weed killer, have you or someone you know been diagnosed with cancer? You’re not by yourself. Lawsuits have been launched by thousands of people in the United States alleging that Roundup’s key component, glyphosate, caused non-Hodgkin lymphoma and other severe health problems. Everything you need to know about the Roundup lawsuit in 2025 will be covered in this guide, including the most significant verdicts, current settlements, who is eligible to submit a claim, and what comes next.
Overview of the Roundup Lawsuit
With good cause, the Roundup lawsuit has become one of the most widely discussed court cases in recent years. Glyphosate, the primary component of the well-known weed killer Roundup, is at the heart of the issue. There are now several claims that the product caused cancer, notably non-Hodgkin lymphoma, in those who used it over the years, sometimes even decades.
In 2018, Bayer purchased Monsanto, the original manufacturer of Roundup. Tens of thousands of lawsuits were filed in response to the transaction. Plaintiffs claim that the company failed to warn users of the risks adequately. Some even claim Monsanto tried to cover up or downplay those risks by manipulating scientific data. In response, Bayer has paid billions in settlements. But in 2025, the fight is far from over.
Why Are People Filing Roundup Lawsuits?
The main problem is that individuals who often used Roundup—on farms, in backyards, at schools, and in parks—later got cancer. Many people are now seeing the connection between their diagnoses and their prolonged exposure to glyphosate.
Non-Hodgkin lymphoma, a blood disease that can be severe and life-altering, is the most prevalent malignancy associated with glyphosate exposure. The plaintiffs contend that, despite being aware of this connection, Monsanto did not issue a sufficient warning. Legally speaking, such is referred to as a “failure-to-warn” allegation.
Common Grounds for Filing a Roundup Lawsuit:
- You’ve been diagnosed with non-Hodgkin lymphoma
- You regularly used Roundup over a long period, either at home or at work
- You weren’t warned about the risks on the product label
Who’s Eligible to File a Roundup Cancer Lawsuit?
You don’t have to be a farmer to be affected. Anyone who used Roundup regularly and later developed cancer could have a claim. That includes:
- Agricultural workers and landscapers
- Maintenance workers at schools and parks
- Homeowners who used it in their gardens
In general, you must demonstrate:
- Documentation attesting to a non-Hodgkin lymphoma or similar cancer diagnosis
- A history of recurring Roundup exposure, especially before 2020, when Bayer started to phase out or reformulate glyphosate in consumer goods
The statute of limitations varies by state and typically ranges from one to three years from the date of diagnosis. Therefore, you must consult a lawyer as soon as possible.
Significant Verdicts in Roundup Lawsuits (2018–2025)
The courts have not been shy about delivering massive verdicts against Bayer. These are some of the most eye-popping examples:
- $2.25 billion – In Pennsylvania (January 2024), a man who used Roundup for decades won this record-setting award. The jury found that Monsanto acted with gross negligence.
- $2.1 billion – In Georgia (March 2025), another landmark case added fuel to the fire. Jurors pointed to internal Monsanto emails that seemed to downplay health risks.
- $611 million – A Missouri court ruling from 2023 that was upheld in 2025.
- $175 million – Pennsylvania (2023), a key win for a retired groundskeeper.
These rulings have influenced thousands of additional cases that are currently ongoing, making them more than merely symbolic.
Will 2025 See a Roundup Settlement?
Yes, but there are complexities to the narrative. In 2020, Bayer agreed to resolve nearly 100,000 cases for approximately $11 billion. Even though that is a vast amount, the lawsuit continued.
As of mid-2025:
- More than 4,400 federal multidistrict litigation (MDL) cases are still active
- Thousands of state-level lawsuits continue
- Bayer is in talks to resolve these remaining claims
There are rumors of another significant settlement on the horizon, particularly in Missouri, where plaintiffs continue to pile on. To limit future exposure, Bayer is also considering filing for Chapter 11 bankruptcy on behalf of Monsanto.
In addition, Bayer agreed to pay the Attorney General of New York $6.9 million for allegedly deceptive advertising regarding the safety of Roundup. Although it was a regulatory action rather than a civil one, it highlights the problems with public confidence.
A Quick Timeline: Roundup Lawsuit History
- 1974: Roundup was first introduced by Monsanto
- 2015: IARC classifies glyphosate as “probably carcinogenic to humans”
- 2018: Bayer acquires Monsanto and inherits ongoing litigation
- 2020: Bayer settles ~100,000 lawsuits for $11 billion
- 2023–2024: Jury awards reach into the billions
- 2025: Supreme Court petition filed over federal preemption; Bayer explores legislative fixes and bankruptcy for Monsanto
The Science Behind the Claims: Is Glyphosate Dangerous?
This is where things get controversial. On one hand, you have the International Agency for Research on Cancer (IARC) calling glyphosate “probably carcinogenic.” On the other hand, the EPA and European regulators say the chemical isn’t likely to cause cancer in humans.
Plaintiffs often point to:
- Epidemiological studies show a 40%+ increased risk of non-Hodgkin lymphoma in frequent glyphosate users
- Allegations that Monsanto ghostwrote favorable studies to downplay risks
- Internal documents revealing concerns about long-term toxicity
Scientific terms and NLP-friendly language: “epidemiological risk of glyphosate,” “glyphosate exposure cancer correlation,” “toxicology review in Roundup case.”
Legal Deep Dive: What Makes These Lawsuits Unique?
Most Roundup lawsuits fall under the umbrella of product liability law. That means plaintiffs have to show:
- The product was defective or dangerous
- The manufacturer failed to warn consumers about risks
- There’s a link between the product and the injury
However, Bayer’s lawyers are employing a robust defense known as federal preemption—specifically, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). They argue that since the EPA approved the product’s label, state courts can’t second-guess it.
So far, the courts are split:
- The Ninth and Eleventh Circuits have allowed failure-to-warn claims to proceed
- The Third Circuit has leaned toward preemption
The Supreme Court could weigh in soon. That decision may determine the future of these lawsuits nationwide.
Long-tail keywords: “FIFRA preemption Roundup lawsuits,” “EPA glyphosate label defense,” “state vs federal product warning law.”
Bayer’s Strategy Moving Forward
Bayer is fighting a war on multiple fronts. Here’s what they’re doing:
- Exploring bankruptcy protection for Monsanto to contain liability
- Lobbying state lawmakers to pass bills limiting glyphosate lawsuits
- Reformulating Roundup products for the residential market
- Continuing settlements in high-risk jurisdictions like California, Missouri, and Pennsylvania
These aren’t just legal moves—they’re corporate survival strategies. Analysts say Bayer’s share price has taken a hit, and public trust continues to erode.
Real People, Real Impact: Plaintiff Stories
One high-profile case involved a retired school groundskeeper who spent decades using Roundup. He said no one ever warned him it could be dangerous. After his cancer diagnosis, he became the face of the legal fight.
Another plaintiff—a vineyard worker from California—used Roundup daily for 15 years. After being diagnosed with non-Hodgkin lymphoma, she joined the MDL. Her story helped sway a jury to deliver one of the billion-dollar verdicts.
These aren’t isolated stories. They reflect a broader problem of product transparency and corporate accountability.
What to Expect If You File a Roundup Lawsuit
Filing a lawsuit starts with a free consultation. If your case has merit, here’s what usually happens:
- Your lawyer collects medical records and product usage history
- Your case is filed in a state court or added to the federal MDL
- You might get a settlement offer
- If no deal is reached, your case could go to trial
Settlement amounts vary:
- Mild cases: $50,000–$150,000
- Severe cases with strong evidence: $500,000–$2 million+
Most attorneys work on a contingency basis, meaning they only get paid if you win.
