The jury in Dewayne Johnson v. Monsanto found the company guilty of concealing the dangers of glyphosate, the world’s most widely used herbicide. Johnson, a terminally ill groundskeeper, was awarded damages totaling $289 million. Monsanto says it will appeal. There are currently 4,000 similar cases already lodged in the US, alleging links to non-Hodgkin’s lymphoma.

Based on the content of internal company documents the jury determined that Monsanto knew of the potential health risks, but failed to warn the public. In his testimony, Johnson told the court, “I never would’ve sprayed the product on school grounds or around people if I knew it would cause them harm. It’s unethical. It’s wrong.”
