Facing billions of dollars in potential liability to cancer victims, Monsanto's parent company said Thursday it would stop selling the current version of Roundup, the world's most widely used herbicide, for U.S. home and garden use in 2023. The forthcoming version of the weed-killer will replace its current active ingredient, glyphosate, with "new formulations that rely on alternative active ingredients," subject to approval by the Environmental Protection Agency and state regulators, said Bayer AG, the German pharmaceutical giant that purchased Monsanto for $63 billion in 2018. The company ... will continue to market the current version of the product for farm use in the United States and for general use in other nations that permit its sale. But while the EPA has found the current version of Roundup to be safe, the International Agency for Research on Cancer, an arm of the World Health Organization, concluded in 2015 that glyphosate was a probable cause of cancer in humans. Tens of thousands of lawsuits have been filed against Monsanto and Bayer in state and federal courts. In the first case to go to trial, a San Francisco jury awarded nearly $290 million in damages in 2019 to Dewayne "Lee" Johnson of Vallejo, who was diagnosed with terminal cancer after spraying the herbicide as a groundskeeper for the Benicia Unified School District. State courts reduced the damages to $21.5 million and rejected the companies' appeal.
