Roundup lawsuit: Guide & Latest Updates (2025)

Basis of the Roundup Class Action Lawsuit

The Roundup class action lawsuit hinges product liability, failure to warn, and scientific evidence regarding glyphosate's carcinogenicity. Plaintiffs argue that Monsanto failed to adequately warn consumers about the potential health risks associated with Roundup despite being aware of scientific studies linking glyphosate to cancer.

The lawsuits depended on whether glyphosate exposure substantially increases cancer risk and if Monsanto/Bayer knowingly concealed these risks from consumers and regulatory authorities. Plaintiffs presented internal company documents and emails suggesting that Monsanto actively worked to downplay the health risks associated with Roundup and influence scientific research in its favor.

In 2018, a landmark verdict in the case of Johnson v. Monsanto saw a California jury awarding $289 million in damages to a groundskeeper who developed terminal cancer after years of Roundup exposure. The verdict sent shockwaves through the agricultural and legal communities, signaling the potential liability faced by Bayer/Monsanto in subsequent lawsuits.

Subsequent rulings and settlements have further shaped the trajectory of the Roundup weed killer lawsuits. Bayer, facing mounting legal pressure and a barrage of lawsuits, opted to settle many cases out of court while continuing to defend Roundup's safety vigorously.

Bayer continues to face lawsuits involving Roundup. There are 4,882 lawsuits pending in a federal multidistrict litigation (MDL) in the Northern District of California. In January 2024, a Philadelphia jury awarded the largest verdict yet in a Roundup claim, totaling $2.25 billion.

Non-Hodgkin's Lymphoma and Roundup Lawsuits (2025)

Non-Hodgkin’s lymphoma affects the lymphatic system, a part of the body's immune system. Many lawsuits involve plaintiffs who developed this disease, one of the more common claims in this litigation.

Science backs up the link between Non-Hodgkin’s Lymphoma and Roundup. Research shows glyphosate causes various health issues, the most severe of which is this disease. Numerous studies, including those cited by the International Agency for Research on Cancer (IARC), found a significant correlation between exposure to glyphosate and the risk of developing this cancer.

Why File a Claim?

The Roundup class action lawsuit and MDL offer profound implications for consumers and corporations. For consumers, the litigation highlights the importance of informed decision-making and the need for transparency regarding product safety and potential health risks.

The outcome of the Roundup weed killer lawsuit may set a precedent for future product liability cases involving alleged harm caused by chemical exposure. If courts continue upholding verdicts against Bayer/Monsanto, it may incentivize companies to prioritize safety testing, regulatory compliance, and transparent communication with consumers regarding potential risks associated with their products.

Most importantly, individuals who suffered as a result of Roundup’s toxicity can seek compensation for the damages accrued and, hopefully, successfully treat their illnesses.

What Proof Do You Need For Roundup Cancer Lawsuit?

The proof in a Roundup cancer lawsuit lies in the exposure period and your disease. As indicated earlier, solid scientific evidence already established links between Roundup’s primary ingredient and these illnesses.

So far, the primary recipients of settlement money in the Roundup class action lawsuit are individuals who have regularly used Roundup in their occupations. This group includes (but is not limited to) landscapers, groundskeepers, agricultural workers, and herbicide production workers.

Other eligible plaintiffs may include any individual who experienced repeated exposure to Roundup. This group includes residents of the neighborhoods surrounding manufacturing plants or agricultural communities.

Roundup is linked to several serious health concerns, primarily (but not limited to) non-Hodgkin lymphoma and possibly several other types of related cancers, including:

• Leukemia
• Prostate Cancer
• Skin Cancer
• Lung Cancer
• Throat Cancer

Cancer symptoms may include swollen lymph nodes, skin lesions, coughing blood, chest pain, swelling, or fatigue. However, some cancer symptoms may be subtle or even appear to be nonexistent without a thorough medical exam.

If you had prolonged exposure to Roundup through your occupation or environment, you may be at risk of cancer and illness. Consider seeking medical attention for adverse symptoms and see if they relate to Roundup exposure.

Other Potential Roundup Conditions

Symptoms and conditions of Roundup exposure vary depending on the duration, frequency, and concentration of exposure and individual susceptibility factors.

Acute exposure to Roundup may result in immediate symptoms such as skin and eye irritation. Chronic or long-term exposure raises more significant concerns about potential health risks beyond cancer, including:

• Respiratory Symptoms: Inhalation of Roundup spray or airborne particles may irritate the respiratory tract, leading to coughing, wheezing, shortness of breath, and throat irritation. Individuals with pre-existing respiratory conditions such as asthma may be more susceptible to respiratory symptoms following Roundup exposure.
• Gastrointestinal Disturbances: Ingesting or accidentally swallowing Roundup through contaminated food or water may result in gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhea.
• Neurological Effects: Some studies have suggested a potential link between glyphosate exposure and neurological symptoms, including headaches, dizziness, fatigue, and cognitive impairment. While these symptoms remain poorly understood, emerging research highlights the need for further investigation into the possible neurotoxicity of glyphosate-based herbicides.
