Health effects of glyphosate[edit]
During March 2015 in an interview by French investigative journalist Paul Moreira, which was first broadcast on French television station Canal+ in September 2014, Moore was asked about the safety of the herbicide glyphosate. Moore told Paul Moreira that one "could drink a whole quart of it" without any harm. When Moore was challenged to drink a glass of the weedkiller, he refused, and ended the interview.[52][53] The interview came shortly after the release of a World Health Organization (WHO) report adding glyphosate to a list of probable carcinogens.
