Does Monsanto’s Roundup weedkiller need a cancer warning?

About this episode

The episode discusses whether Monsanto's Roundup weedkiller should carry a cancer warning as the Supreme Court hears a related case.

Should companies be legally required to warn consumers that their product might cause cancer? If your company is selling tobacco, that answer has been yes since 1965. But what if your product is just for lawns and is regulated by the EPA? That’s precisely what the Supreme Court is being asked to decide. The man at the heart of a lawsuit against Monsanto says a warning or a change in marketing might have altered the course of his life. On Monday, the court heard the case of John Durnell, known as the “spray guy,” whose $1.25 million verdict against Monsanto, is being challenged . USA TODAY Supreme Court Correspondent Maureen Groppe joins The Excerpt for more on Monday's arguments.
