Roundup Lawsuit — Glyphosate Herbicide & Non-Hodgkin’s Lymphoma

Roundup, Monsanto’s blockbuster herbicide, has caused non-Hodgkin’s lymphoma in farmers, landscapers, and consumers with significant exposure. Lawyers from Trial Lawyers United represent individuals diagnosed with NHL and related B-cell lymphomas who used or were exposed to Roundup.

What is Roundup?

Roundup is a herbicide containing glyphosate as its active ingredient, produced by Monsanto (acquired by Bayer in 2018). Glyphosate was patented as an herbicide in 1974 and marketed as a broad-spectrum, non-selective weed killer. Roundup became the world’s most widely used herbicide: applied to crops, used by landscapers and homeowners, and present in many food products. The product is often described as safe for human health. However, independent scientific research contradicts this marketing message.

IARC Determination: Glyphosate as a Probable Human Carcinogen

In 2015, the International Agency for Research on Cancer (IARC), a division of the World Health Organization, classified glyphosate as ‘probably carcinogenic to humans’ (Group 2A). This classification was based on:

  • Strong epidemiological evidence in agricultural workers showing elevated NHL risk.
  • Experimental evidence of carcinogenicity in animal models.
  • Mechanistic evidence suggesting how glyphosate damages DNA.

The IARC classification does not guarantee liability in court, but it represents the judgment of the world’s foremost cancer research organization.

Epidemiological Evidence: Glyphosate and Non-Hodgkin’s Lymphoma

  • Meta-analyses of occupational cohorts show approximately 41% higher NHL risk in individuals with regular glyphosate exposure compared to unexposed populations.
  • Exposure-response relationship: Risk increases with duration and intensity of exposure.
  • Agricultural populations: Farmers, farm workers, and applicators show the highest measured exposures.
  • Landscaping and grounds maintenance: Occupational exposure through job-related herbicide application.
  • Residential exposure: Homeowners using Roundup for weed control.

Monsanto’s Misconduct: Evidence of Fraud and Negligence

Internal Monsanto documents produced in litigation reveal a pattern of deception:

  • Ghostwritten studies: Monsanto funded research then presented it as independent science, concealing its financial interest.
  • Regulatory capture: Monsanto lobbied EPA and other agencies to downplay glyphosate risks.
  • Discrediting scientists: Monsanto attacked and attempted to discredit independent researchers publishing evidence of glyphosate toxicity.
  • Suppressed internal research: Studies showing potential health risks were not disclosed to regulators or the public.
  • Marketing deception: Promoted glyphosate as safe while aware of scientific evidence of carcinogenic potential.

Who May Qualify for a Roundup Claim?

  • Farmers with long-term Roundup application in crop production (especially corn, soy, and canola).
  • Landscapers, groundskeepers, and grounds maintenance workers with occupational herbicide application.
  • Farm workers and agricultural laborers with field exposure.
  • Licensed pesticide applicators using Roundup professionally.
  • Home gardeners and homeowners with significant, repeated residential Roundup use.
  • People living near treated agricultural fields with direct or drift exposure.
  • All must have a documented NHL or related B-cell lymphoma diagnosis.

Cancers Associated with Glyphosate Exposure

Roundup litigation encompasses multiple B-cell lymphomas with the same presumed mechanism:

  • Non-Hodgkin’s lymphoma (NHL): Broad category of lymphoid malignancies.
  • Diffuse large B-cell lymphoma (DLBCL): Aggressive subtype.
  • Chronic lymphocytic leukemia (CLL): B-cell malignancy affecting blood and bone marrow.
  • Multiple myeloma: Plasma cell malignancy.
  • Small lymphocytic lymphoma (SLL): Indolent subtype.

MDL 2741: Roundup Litigation Consolidated in Northern California

Thousands of Roundup cases are consolidated in Multi-District Litigation (MDL) No. 2741 in the U.S. District Court for the Northern District of California. This MDL includes consolidated discovery, expert testimony, and bellwether trials to establish causation and damages.

Key Verdicts: Juries Have Found for Plaintiffs

Multiple bellwether trials have resulted in jury verdicts awarding substantial damages to Roundup plaintiffs. While specific award amounts vary by jurisdiction and individual circumstances, these verdicts establish that juries recognize the link between Roundup exposure and NHL and are willing to hold Monsanto/Bayer accountable. We encourage you to discuss case value and verdict outcomes during your free consultation.

Evidence Needed to Support Your Claim

  • Documentation of Roundup exposure: receipts, application records, work history, expert reconstruction of exposure.
  • Medical records: NHL diagnosis, pathology reports, staging documents, treatment records.
  • Temporal relationship: diagnosis within reasonable latency period after exposure.
  • Occupational or residential history establishing opportunity for exposure.

Frequently Asked Questions

I used Roundup at home. Can I file a claim?

Yes, if you used Roundup frequently over an extended period and developed NHL. We assess residential cases on a case-by-case basis, looking at frequency of use, whether protective equipment was worn, and timing relative to diagnosis.

Does EPA approval of glyphosate mean I cannot sue?

No. Regulatory approval does not shield manufacturers from liability for injuries or for fraud in obtaining that approval. We will examine Monsanto’s conduct before the EPA, including potentially misleading submissions about glyphosate safety.

What if I was exposed decades ago?

The statute of limitations begins when you discovered (or reasonably should have discovered) that your NHL was caused by Roundup. Even if exposure was decades ago, your claim may not be time-barred. We evaluate tolling and timely filing.

Do I need to prove Monsanto knew glyphosate causes cancer?

We must prove that Monsanto knew (or should have known) of the carcinogenic risk and failed to warn. Internal documents and scientific evidence from the time of exposure can establish knowledge. We do not need to prove intentional wrongdoing, only negligence or breach of warranty.

In the Relentless Pursuit of Justice | Results Without Risk

The mass tort litigation described on this website is based on publicly available information about ongoing legal proceedings. Case status, MDL rulings, settlement programs, and qualification criteria are subject to change. The information on this page is current as of the date indicated and may not reflect the most recent developments in the litigation.

Filing a case inquiry or contacting our office does not guarantee that you have a viable claim. All potential claims are subject to individual evaluation, including a review of your exposure history, medical records, and the applicable statute of limitations in your state.

Statute of Limitations Warning

Time limits apply. Every state sets its own deadline for filing a personal injury or mass tort claim. These deadlines, known as statutes of limitations, vary by state, by the type of claim, and by individual circumstances such as the date of diagnosis or discovery of the injury. Failing to file within the applicable deadline may permanently bar your right to seek compensation. If you believe you have a claim, contact an attorney promptly to determine the filing deadline that applies to your situation.

No Guarantee of MDL or Class Participation

References to multidistrict litigation (MDL), class actions, or coordinated proceedings on this website do not guarantee that your individual case will be filed in or accepted into any particular proceeding. Case placement depends on jurisdiction, venue rules, and the procedures established by the presiding court.

Trial Lawyers United LLC handles personal injury and mass tort cases on a contingency fee basis. This means you pay no attorney fees unless and until we obtain a recovery on your behalf. If there is no recovery, there is no attorney fee. Contingency fees are calculated as a percentage of the gross recovery. In most cases, the client is also responsible for litigation costs and expenses, which may include court filing fees, expert witness fees, deposition costs, medical record retrieval, investigation expenses, travel, and other costs necessarily incurred in the prosecution of the case. These costs may be advanced by the firm during the pendency of the case and are typically deducted from the gross recovery in addition to the attorney fee. The specific percentage and the method by which expenses are calculated (whether deducted before or after the contingency fee is computed) will be set forth in the written fee agreement between the client and the firm, which must be signed before representation begins.

"No Fee Unless We Win" Qualifier

When we say "no fee unless we win," we mean that you will not be charged attorney fees if we do not recover compensation on your behalf. Litigation costs and expenses are separate from attorney fees and are addressed in the written fee agreement.
