Title: Philadelphia jury awards $78 million to man who said his cancer was caused by Roundup weed killer
[Philly Voice 11/10/25] -- William Melissen, 51, of Abington, is the latest person to receive a payout from the wave of litigation against manufacturer Monsanto. Mr Melissen has been awarded $78 million in a product liability lawsuit that alleged an ingredient in Roundup weed killer caused him to develop blood cancer.
The decision was made by a jury in Philadelphia, resolving one of numerous lawsuits against Roundup manufacturer Monsanto and its parent company, Bayer AG.
Mr Melissen filed the lawsuit in 2021 after he was diagnosed with non-Hodgkin lymphoma a year earlier. He said he had been using Roundup at home and at work since 1992.
The weed killer contains the herbicide glyphosate, which is widely used in large-scale agriculture and hundreds of products sold around the world.
