California jury awards $332 million to man who blamed his cancer on use of Monsanto weedkiller

On October 31, 2023, a San Diego Superior Court jury awarded $332 million to Mike Dennis, 57, who sued chemical giant Monsanto Co. contending that his cancer was related to decades of using its Roundup weedkiller.

He was diagnosed in 2020 with a rare form of non-Hodgkin's lymphoma. His lawsuit contended that his illness was related to Roundup's active ingredient, glyphosate.

The jury found that Monsanto, which is now a division of pharmaceutical and biotechnology giant Bayer, failed to provide warnings of Roundup's risks. But jurors also ruled partially in Bayer's favor by finding the product design wasn't defective and the company wasn't negligent.

Dennis was awarded $7 million in compensatory damages and $325 million in punitive damages.

Bayer bought Monsanto for $63 billion in 2018 and has been dealing with thousands of claims and lawsuits related to Roundup. In 2020, Bayer announced it would pay up to $10.9 billion to settle some 125,000 filed and unfiled claims.
