Jury Says Roundup Weed Killer Likely Caused Man’s Cancer

A federal jury found Tuesday that Monsanto's popular weedkiller Roundup was a "substantial factor" in causing a California man's cancer, dealing a significant blow to the company as it aggressively defends its products against thousands of similar claims.

One of the experts called by Hardeman's team suggested that Roundup is even more risky than glyphosate on its own, because of additives in the weed killer.

After five days of deliberation the jury concluded the weed killer was a "substantial factor" in causing non-Hodgkins lymphoma in Edwin Hardeman, a 70-year-old Sonoma County man.

Bayer continues "to believe firmly that science confirms that glyphosate-based herbicides do not cause cancer". Bayer said that it would appeal the award and decision entirely.

The current case is seen as a "bellwether" for hundreds of other pending lawsuits in the US. During the second phase, Hardeman's lawyers will present evidence to show that Monsanto knew glyphosate was harmful and likely cancer-causing, yet the company ignored the dangers and even concealed them from consumers. Bayer was previously charged with a fine of Dollars 289 Million after failing to warn customers of the cancer causing agents within Roundup and Ranger Pro. In Mr Johnson's case, the jury found Monsanto had "acted with malice or oppression" and awarded him US$289 million in damages.

The next stage of the trial will consider Bayer's liability and damages.

The latest ruling suggests Bayer is "the underdog in numerous reported 11,200 cases pending across the U.S.", Holly Froum, a legal analyst at Bloomberg Intelligence, wrote in a report.


Bayer AG slumped after a second major defeat in USA litigation over claims that its Roundup weed killer causes cancer, shaving nearly US$8 billion from its market value and raising the likelihood of a costly settlement.

Bayer had claimed that jury was overly influenced by plaintiffs' lawyers allegations of corporate misconduct and did not focus on the science.

Hardeman had chemotherapy for non-Hodgkin lymphoma in 2015.

Now the trial will enter a second phase to determine whether Monsanto is liable for damages.

The EU's executive body, the European Commission, pointed to the approval of glyphosate by its two scientific agencies, the European Food Safety Authority and the European Chemicals Agency, which do not classify the substance as carcinogenic.

According to the National Pesticide Information Center, glyphosate has been linked to causing cancer through various studies.

Studies commissioned by the United Nations' World Health Organization have delivered conflicting results, however one of those studies, conducted by the WHO's International Agency for Research on Cancer said it is "probably carcinogenic to humans".
