‘Junk science’? Judge and UCLA scientist square off in glyphosate-cancer lawsuit

Returning to the witness stand, a scientist on Wednesday [April 4] defended her opinion that Monsanto’s popular weed killer Roundup causes cancer.

UCLA epidemiologist Dr. Beate Ritz was invited back to court after she and other scientists spent a week testifying in March about whether glyphosate, the active ingredient in the world’s most popular weed killer, causes Non-Hodgkin’s Lymphoma in humans.

Ritz’ testimony could advance more than 300 lawsuits filed against Monsanto and consolidated in a multidistrict case in San Francisco. The suits were filed by farmers and landscapers who say exposure to Roundup’s active ingredient caused them to develop cancer of the lymph nodes, organs crucial for a properly functioning immune system.

U.S. District Judge Vince Chhabria must decide whether there is adequate scientific evidence to support the plaintiffs’ claims against Monsanto.

Dismissing arguments that she failed to consider exposure to other pesticides in her analysis, Ritz told Chhabria … that “over-adjusting” the numbers can bias the results.

Ritz was responding to criticism from Monsanto and Chhabria, who last month dismissed some of her opinions as “junk science” because she failed to account for exposure to carcinogenic pesticides in her analysis.
