Roundup et al. and cancer

In 2015 the World Health Organization’s International Agency for Research on Cancer issued a report identifying glyphosate, malathion and diazinon as probable carcinogens and tetrachlorvinphos and parathion as possible carcinogens (Roundup contains glyphosate but also inert ingredients, some of which the manufacturer is allowed to keep secret):

A Working Group of 17 experts from 11 countries met at the International Agency for Research on Cancer (IARC) on 3–10 March 2015 to review the available published scientific evidence and evaluate the carcinogenicity of five organophosphate insecticides and herbicides: diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos.

One thought on “Roundup et al. and cancer

  1. Hi Nathaniel,
    I have been working in our borough to help them to move to an environmental alternative to spraying toxic poisons for weed control throughout the borough. I see you have some things in the works for West Chester. Any suggestions on how I can move them past the 50 year of spraying resistance to something different. I need more people to help, and someone with more knowledge and experience than myself. Unfortunately, we don’t have very many in the community that are even educated to know it’s being done. I’m willing to help but I cannot continue to try and do this without real support. Thank you for any help and direction you can give me. Charl A. Wellener
