Golf Course Groundskeepers and Roundup: The Cancer Risk No One Warned You About

You kept the course looking flawless. Weeds cleared from the cart paths, edges sharp, greens pristine. For years, that meant reaching for the weed killer week after week, season after season. Now you’ve been diagnosed with non-Hodgkin lymphoma, and a question keeps nagging at you: could the chemicals you sprayed all those years have caused this?

It’s a fair question, and it deserves a real answer. Thousands of workers across the country have connected their non-Hodgkin lymphoma to years of glyphosate exposure — the active ingredient in Roundup. Golf course and grounds crews often had heavy, routine contact with this chemical, yet they’re rarely the people you see in Roundup advertising. If your job put glyphosate on your hands, your clothes, and in the air you breathed, you may have legal options worth exploring.

How Glyphosate Was Used on Golf Courses and Grounds Jobs

Keeping large properties weed-free is a constant battle, and for decades, glyphosate was the standard tool. If you worked in turf management or grounds maintenance, you likely used it more often than almost anyone — often without protective gear or any warning about long-term risks.

Here’s how exposure typically happened on the job:

• Spot-spraying and broadcast application. Grounds crews sprayed glyphosate along cart paths, fence lines, bunker edges, parking areas, and the rough to keep unwanted growth down.
• Mixing and loading. Preparing the herbicide meant handling concentrated product, which brought direct skin contact and inhaled fumes.
• Backpack and hand-wand spraying. Applying weed killer by hand put the chemical inches from your body, drifting onto skin and clothing all day.
• Contaminated clothing and gear. Residue soaked into shirts, gloves, and boots and stayed with you through the workday and beyond.
• Enclosed and poorly ventilated spaces. Mixing chemicals in maintenance sheds, equipment barns, or storage rooms could concentrate fumes in tight areas with little airflow.

This wasn’t occasional. Grounds work is repetitive by nature, so many workers sprayed or handled glyphosate several times a week across an entire career. That kind of sustained, repeated exposure is exactly what matters most in these claims. Routine glyphosate use in grounds maintenance meant many workers faced years of heavy, direct exposure — often in enclosed spaces without protection.

The Science Linking Glyphosate to Non-Hodgkin Lymphoma

These cases exist because of a growing body of research connecting glyphosate to non-Hodgkin lymphoma (NHL), a cancer that affects the body’s immune system.

A few key points help explain the concern:

• In 2015, the International Agency for Research on Cancer (IARC), part of the World Health Organization, classified glyphosate as “probably carcinogenic to humans.”
• Multiple studies have examined a link between glyphosate exposure and an increased risk of non-Hodgkin lymphoma.
• Lawsuits allege the manufacturer knew about potential cancer risks for years but failed to adequately warn workers and the public.

Here’s what matters for grounds crews specifically: research and litigation have generally focused on the amount and duration of exposure. The people with the strongest documented connection are often those with heavy, long-term contact — which describes many turf and grounds workers precisely.

To be clear, science doesn’t claim that every case of NHL comes from glyphosate. But the documented association is why courts have taken these claims seriously, and why grounds workers with a diagnosis deserve a closer look at their exposure history. Glyphosate has been linked to non-Hodgkin lymphoma, and heavy, long-term exposure is exactly the kind courts have scrutinized most closely.

How California Law Applies After the Recent Supreme Court Ruling

A recent Supreme Court decision reshaped Roundup litigation, so it’s important to be straight with you about where things stand.

In 2026, the Court ruled that a federal pesticide law preempts state-law failure-to-warn claims. In plain terms, you can no longer sue in state court by arguing the company failed to put an adequate cancer warning on the label. That claim had long been the strongest tool in Roundup cases, so its loss is significant.

But the ruling did not end Roundup litigation. It targeted one specific claim. Other legal theories under California law may still be available:

• Design defect. This argues the product itself was unreasonably dangerous because of how it was formulated — separate from anything on the label. Because this claim isn’t about the warning, it may not fall under the same preemption.
• Manufacturing defect. This applies when something went wrong in producing a specific batch of the product.
• Other non-labeling claims. Certain claims that don’t hinge on the content of the federally approved label may still have room to proceed.

Under California’s strict liability rules, an injured person often doesn’t have to prove the manufacturer was careless — only that the product was defective and that the defect caused harm. With failure-to-warn now limited, the focus in many cases shifts toward design defect and whether Roundup was unreasonably dangerous as made.

These surviving theories are more complex and fact-specific than a failure-to-warn claim. Whether they fit your situation takes careful legal analysis — which is exactly why an early case review matters so much right now. The Supreme Court limited failure-to-warn claims, but design defect and other theories under California’s strict liability law may still offer a path forward.

Who May Qualify for a Claim

You may be wondering whether your situation counts. Generally, people pursuing these claims share two things in common:

• Significant, repeated glyphosate exposure — often through years of spraying, mixing, or handling Roundup on the job.
• A diagnosis of non-Hodgkin lymphoma — the cancer most closely tied to glyphosate in these cases.

You may want to have your situation reviewed if you worked in roles like:

• Golf course superintendent, greenskeeper, or turf-management crew member
• Municipal parks and recreation grounds worker
• School or university grounds maintenance crew member
• Cemetery, HOA, or commercial property groundskeeper
• Landscaper or maintenance worker who mixed, loaded, or sprayed weed killer regularly

And you were later diagnosed with non-Hodgkin lymphoma.

Your exposure doesn’t have to be recent. Roundup has been widely used for decades, and NHL can develop years after exposure ends. If a loved one who worked in grounds maintenance has since passed away from non-Hodgkin lymphoma, a surviving family member may be able to pursue a claim on their behalf.

Because the law is shifting after the Supreme Court’s ruling, eligibility now depends heavily on the specific facts of your exposure and the legal theories that survive. The only reliable way to know where you stand is to talk with an attorney familiar with the current landscape. If you had years of hands-on glyphosate exposure in grounds or turf work and were later diagnosed with non-Hodgkin lymphoma, your situation is worth reviewing.

What Damages You May Be Able to Recover

A cancer diagnosis reshapes every part of your life, and California law allows you to seek compensation for the full scope of that harm. Depending on your case, recoverable damages may include:

• Medical expenses — past and future costs for treatment, chemotherapy, and ongoing care
• Lost wages — income missed during treatment and recovery
• Lost earning capacity — reduced ability to do physically demanding grounds work going forward
• Pain and suffering — the physical and emotional toll of cancer and its treatment
• Emotional distress — the anxiety and strain a diagnosis brings to you and your family
• Loss of consortium — the impact on your relationship with your spouse

The severity of your illness and the strength of your evidence tend to shape what a claim is worth. Because non-Hodgkin lymphoma often requires intensive, long-term treatment, future care needs can make up a substantial part of a claim. For workers whose livelihood depends on physical labor, lost earning capacity can also weigh heavily.Compensation can cover far more than medical bills — including lost income, future care, and the profound personal toll of cancer.

The California Deadline You Can’t Afford to Miss

California sets a firm time limit on these claims through the statute of limitations. Miss that window, and you can lose the right to pursue compensation entirely — no matter how strong your case might be.

These deadlines can be especially tricky in cancer cases. The clock often starts when you discovered, or reasonably should have discovered, that glyphosate may have caused your illness — not necessarily when the exposure happened. Because grounds work often spans many years and employers, and because that discovery date can be genuinely complicated, having your situation reviewed promptly is the safest step.

Acting early also protects your evidence. Employment records from golf courses, parks departments, or school districts, product-use documentation, and coworkers who can confirm your exposure all become harder to track down as time passes.

 If you suspect Roundup caused your non-Hodgkin lymphoma, start writing down your work history — which courses or properties, which years, and what you sprayed or handled — and treat the legal clock as already running. A firm, sometimes complicated deadline applies — and with the law shifting, acting quickly protects both your rights and your evidence.
