A pro-Monsanto scientist who insisted during a television interview that Roundup is perfectly safe to drink refused to consume a glass of the weed killer on-air after being challenged by the host.
"You can drink a whole quart of it and it won't hurt you," Dr. Patrick Moore told French cable channel Canal+ for an upcoming documentary.
"You want to drink some? We have some here," the host asked.
"I'd be happy to actually. Not really, but I know it wouldn't hurt me," Moore replied.
"If you say so, I have some," the host quipped back.
"No, no. I'm not stupid," Moore answered. "People try to commit suicide with it and fail regularly."
The French cable host pressed.
"Let's tell the truth," he said.
"It's not dangerous to humans," he said. "No, it's not."
"So are you ready drink a glass of glyphosate?" he asked.
"No I'm not an idiot," Moore said before abruptly ending the interview and calling the host a "jerk."
Roundup was recently named as a probably carcinogen by the International Agency for Research on Cancer due to the use of glyphosate as an ingredient. Monsanto strongly disagreed with the decision.
Moore, who has been called a Monsanto lobbyist, told The Huffington Post he is not.
"Knowledgeable scientists, consumers and our farmer customers may be familiar with and confident in the safety of glyphosate, but their statements don’t make them lobbyists for our company," a spokesperson told the website. "Dr. Patrick Moore is one of those individuals. He agrees with the science that supports the safety of glyphosate, and is an advocate for technology and innovation. But Dr. Patrick Moore is not and never has been a paid lobbyist for Monsanto."
