Plaintiffs say the herbicide Roundup can cause non-Hodgkin's lymphoma
The company says there's no evidence the ingredient glyphosate causes cancer
Christine Sheppard fantasizes about her life before cancer. Before she had to take painkillers “all the time.” Before she had to seriously worry about when she might die.
“I found out something was wrong because my right leg swelled up enormously,” Sheppard said. “They did an ultrasound and found I was completely full of these lymph nodes. It was stage IV large-cell lymphoma.”
Grueling chemotherapy treatments have started robbing her of mobility. “It’s a strange nerve thing,” she said. “I don’t always know where my feet are. I have to look down to see where they are.”
And the symptoms “will be progressively worse. There’s no cure. Eventually, I will probably end up fairly immobilized.”
For 12 years, Sheppard had no idea what might have caused her non-Hodgkin’s lymphoma – until a group of cancer researchers reported that glyphosate, the key ingredient in the popular weed killer Roundup, is “probably carcinogenic to humans.”
That’s the same herbicide Sheppard said she sprayed on her coffee farm in Hawaii for five years.
“I was incensed,” said Sheppard, 67. “We had no idea.”
Sheppard is one of more than 800 cancer patients suing Monsanto, the maker of Roundup, claiming the company failed to warn consumers about the risk of cancer associated with Roundup products.
Monsanto says there’s no proof that glyphosate is carcinogenic. In fact, it cites a report by the Environmental Protection Agency’s Cancer Assessment Review Committee that said glyphosate is “not likely to be carcinogenic to humans.”
But the former chairman of that committee offered to stop an independent review on whether glyphosate could cause cancer, according to a plaintffs’ motion to compel his deposition. And that has left Sheppard even more incensed.
Health agency: Glyphosate is ‘probably carcinogenic’
“For the herbicide glyphosate, there was limited evidence of carcinogenicity in humans for non-Hodgkin lymphoma,” the report states.
“The evidence in humans is from studies of exposures, mostly agricultural, in the USA, Canada, and Sweden published since 2001. In addition, there is convincing evidence that glyphosate also can cause cancer in laboratory animals.”
That report spurred hundreds of non-Hodgkin’s lymphoma patients to sue Monsanto.
Timothy Litzenburg’s law firm represents more than 500 of them. He said most of the patients didn’t know about a possible link between Roundup and non-Hodgkin’s lymphoma until the report came out.
“It would not surprise me in the least if there are 2,000 to 3,000 cases by the end of the year,” Litzenburg said. “This is the most-used herbicide in the world … from the largest farm operations to backyard gardens. It’s ubiquitous.”
But many other companies also sell products containing glyphosate. Why aren’t they targeted in these lawsuits?
“This is an oversimplistic answer, but Monsanto invented/discovered it, they held the patent for many years, they are the EPA registrant for glyphosate, and they continue to dominate the market,” the attorney said.
“Furthermore, we are not alleging that our clients got cancer from glyphosate alone. We are suing because our clients got cancer from Roundup. … Roundup contains animal fats and other ingredients that increase the carcinogenicity of the glyphosate.”
Monsanto spokeswoman Charla Lord flatly denied those accusations.
“Glyphosate-based herbicides, including Roundup-brand formulated products with surfactants, all have a long history of safe use and do not pose any unreasonable risk to human health when used according to label directions,” Lord said.
“The safety of each labeled use of a pesticide formulation must be evaluated and approved by regulatory authorities before it is authorized for sale.”
Sheppard said she knows skeptics will say she can’t prove that her cancer came from using Roundup. But she said the hundreds of plaintiffs with similar stories – combined with the report – show “such strong circumstantial evidence that the total adds up.”
“In fact, since IARC classified glyphosate, regulatory authorities in the United States, Europe, Canada, Japan, New Zealand and Australia have publicly reaffirmed that glyphosate does not cause cancer,” Lord said.
For example, the European Chemicals Agency said last month that glyphosate is “not classified as a carcinogen.”
