Monsanto faces nearly 54,000 Roundup cancer lawsuits

Monsanto and Bayer AG are facing nearly 54,000 lawsuits filed on behalf of consumers who allege that they were diagnosed with non-Hodgkin’s lymphoma or other cancers after using the herbicide Roundup.

According to these lawsuits, Bayer and Monsanto – the company that originally developed Roundup – failed to warn farm workers, gardeners, and other individuals that glyphosate – the active chemical in the herbicide – could increase their risk of developing non-Hodgkin’s lymphoma or other cancers.

Concerns about the cancer risks of Roundup first arose in 2015, when a study conducted by the World Health Organization (WHO) found that exposure to glyphosate was probably carcinogenic to humans. Because Roundup was the most commonly used herbicide in the world since it was developed in the 1970s, these findings implied that tens of thousands of Roundup users may have been exposed to potentially carcinogenic chemicals while farming, gardening, or doing landscape work.

The most common type of cancer associated with exposure to glyphosate is non-Hodgkin’s lymphoma, a type of cancer that originates in the lymphatic system. Roundup users may also be at risk of developing other types of lymphoma cancers, including Burkitt lymphoma, follicular lymphoma, hairy cell lymphoma, large B-cell lymphoma, mantle cell lymphoma, peripheral T-cell lymphoma, and skin lymphoma.

Several European countries – including Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Italy, Luxembourg, the Netherlands, Portugal, Scotland, Slovenia, Spain, Sweden, Switzerland, and the United Kingdom – have announced that they would ban or restrict the use of Roundup in response to the cancer concerns associated with the herbicide.

Bayer Faces Billions in Damages from Roundup Litigation

The first Roundup lawsuit against Bayer and Monsanto was filed in 2016 by a groundskeeper who was diagnosed with non-Hodgkin’s lymphoma after years of working with the chemical. Following a $78 million verdict in his favor, two more lawsuits against Monsanto and Bayer went to trial in California in 2019. Jurors awarded damages of $80 million and $55 million, respectively, to the plaintiffs in each of these trials.

In the wake of these verdicts, tens of thousands of other individuals who were diagnosed with non-Hodgkin’s lymphoma or other cancers after exposure to Roundup or glyphosate filed lawsuits against Monsanto and Bayer. Nearly 100,000 Roundup lawsuits have been filed as of July 2024.

So far, the two companies have been ordered to pay about $11 billion in damages in connection with the Roundup litigation.
