A California woman suing Monsanto over allegations that her use of Roundup weed killer caused her to develop cancer testified Monday that she had a hard time remembering many details about the extent of her use of the pesticide, struggling to answer several questions posed by a Monsanto attorney.
In cross examination, Monsanto attorney Bart Williams pressed plaintiff Donnetta Stephens on how much and when she had used the company’s popular herbicide before she was diagnosed with non-Hodgkin lymphoma in 2017. Peppering Stephens with questions about changes in information she provided in depositions and interrogatories, the company’s lawyer sought to cast doubt on the span and volume of her actual use and exposure.
In testimony last week, Stephens’ son David Stephens recalled his mother’s frequent use of Roundup and her tendency to wear sleeveless shirts and shorts when outside spraying the weed killer. He described recalling her use when he was a child and seeing that use continuing when he was an adult.
But in Monday’s testimony, Williams sought to undermine Donnetta Stephens credibility, implying that her son and husband were the architects of many of her answers about her use of Roundup provided in pre-trial documents.
He said that Stephens and her husband had “changed your story about the length of time you had used Roundup,” saying initially her use dated back to 2003 but then saying the use began in 1985.
Stephens acknowledged that her memories of her use were aided by information from her family.
“You and I agree that one should not swear to something, accuracy, if you don’t know whether it is true or not. That is my question,” Monsanto’s lawyer addressed Stephens.
“At that time, I believed it to be true, yes sir,” she replied.
“You believed it to be true solely because that’s what your husband or your son said, correct?” Williams asked.
“Yes,” Stephens answered.
The line of questioning was anticipated in a June filing by Stephens’ lawyers, explaining to the judge that Stephens is in frail health after six cycles of chemotherapy and has suffered significant memory loss, making her “unable to recall certain Roundup exposures.”
She had told lawyers initially that her exposure extended over 14 years but amended that to say it was closer to 30 years after being reminded of her use of Roundup products at a property where she had previously lived, according to her lawyers.
In their June filing, Stephens lawyers said Monsanto’s attorneys were accusing them and Stephens of “engaging in gamesmanship,” and allegation they denied.
Stephens testified that she does remember that sometimes when she was spraying Roundup the wind would blow spray onto her bare skin. She said she would not immediately wash it off, showering only after she completed her yardwork.
“It was all over me,” Stephens said.
At one point Monsanto’s attorney asked Stephens about her relationship with her children. When Stephens insisted she was close to her children, Monsanto’s attorney played a video deposition of a previous statement she had made saying the opposite.
Longtime Monsanto scientist Donna Farmer is scheduled to testify Tuesday.
Monsanto is owned by Germany’s Bayer AG. Bayer bought Monsanto in 2018.
Stephens’ trial is a “preference” case, meaning her case was expedited after her lawyers informed the court that Stephens was “in a perpetual state of pain” and losing cognition and memory.
The case is being tried in the Superior Court of San Bernardino County in California under the oversight of Judge Gilbert Ochoa. It is the fourth Roundup cancer trial to take place in the United States and the first since 2019. Juries in all three prior trials found in favor of the plaintiffs, agreeing with claims that Monsanto’s glyphosate-based weed killers, such as Roundup, cause non-Hodgkin lymphoma and Monsanto spent decades covering up the risks, and failing to warn users.
Stephens is one of tens of thousands of plaintiffs who filed lawsuits against Monsanto after the World Health Organization’s cancer experts classified glyphosate as a probable human carcinogen with an association to non-Hodgkin lymphoma.
The three prior trials were all lengthy, in-person proceedings loaded with weeks of highly technical testimony about scientific data, regulatory matters and documents detailing internal Monsanto communications.
Stephens trial is being held via Zoom due to concerns about the spread of Covid-19, and numerous technical difficulties have plagued the proceedings. On Monday, the trial was stopped several times because jurors lost connections or had other problems that inhibited their ability to hear and view the trial testimony.
