Jury Backs Man Claiming Roundup Weed Killer Caused Cancer

A San Francisco jury has ordered agribusiness giant Monsanto to pay $289 million to a former school groundskeeper dying of cancer, saying the company’s popular Roundup weed killer contributed to his disease.

Dewayne Johnson’s lawsuit was the first of thousands of cases filed in state and federal courts alleging that Roundup causes cancer, which Monsanto denies.

Johnson said he hoped his verdict would bolster the other cases.

Jurors in California superior court agreed the product contributed to Johnson’s cancer and the company should have provided a label warning of the potential health hazard. Johnson’s attorneys sought and won $39 million in compensatory damages and $250 million of the $373 million they wanted in punitive damages.

Monsanto has denied a link between the active ingredient in Roundup — glyphosate — and cancer, saying hundreds of studies have established that the weed killer is safe.

Monsanto spokesman Scott Partridge said the company will appeal. Partridge said scientific studies and two government agencies have concluded that Roundup does not cause cancer.

Johnson used Roundup and a similar product, Ranger Pro, as a pest control manager at a San Francisco Bay Area school district, his lawyers said. He sprayed large quantities from a 50-gallon tank attached to a truck, and during gusty winds, the product would cover his face, said Brent Wisner, one of his attorneys.

Once, when a hose broke, the weed killer soaked his entire body.

Johnson read the label and even contacted the company after developing a rash but was never warned it could cause cancer, Wisner said. He was diagnosed with non-Hodgkin’s lymphoma in 2014 at age 42.

But George Lombardi, an attorney for Monsanto, said non-Hodgkin’s lymphoma takes years to develop, so Johnson’s cancer must have started well before he began working at the school district.

The U.S. Environmental Protection Agency says Roundup’s active ingredient is safe for people when used in accordance with label directions.

However, the France-based International Agency for Research on Cancer, which is part of the World Health Organization, classified it as a “probable human carcinogen” in 2015. California added glyphosate to its list of chemicals known to cause cancer.
