Following its meeting in March 2015, IARC has released the first of a series of monographs assessing the carcinogenic potential of some organophosphate insecticides and herbicides. The Working Group classified glyphosate in Group 2A (“probably carcinogenic to humans”) on the basis of an increased incidence of tumours at multiple sites in rats and mice treated orally.

Monographs on the following compounds are due to be made available shortly:

  • diazinon (Group 2A: “probably carcinogenic to humans”)
  • malathion (Group 2A: “probably carcinogenic to humans”)
  • parathion (Group 2B: “possibly carcinogenic to humans”)
  • tetrachlorvinphos (Group 2B: “possibly carcinogenic to humans”)

International Agency for Research on Cancer (2015). IARC Monographs on the Evaluation of Carcinogenic Risks to Humans. Volume 112. Some organophosphate insecticides and herbicides: diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos.
