A U.S. jury on Wednesday awarded $80 million to a man who claimed his use of Bayer AG's glyphosate-based weed killer Roundup caused his cancer, in the latest legal setback for the company facing thousands of similar lawsuits.

The jury in San Francisco federal court said the company was liable for plaintiff Edwin Hardeman's non-Hodgkin's lymphoma.

It awarded $5 million in compensatory damages and $75 million in punitive damages to Hardeman after finding that Roundup was defectively designed, that Monsanto failed to warn of the herbicide's cancer risk and that the company acted negligently.
