Roundup® Glyphosate Herbicide Classified as “Probably Carcinogenic”

The International Agency for Research on Cancer in Lyon, France has classed the world’s most widely used herbicide as “probably carcinogenic”.  The agency cites links to various rare cancers including non-Hodgkin lymphoma.

Glyphosate is used in more than 750 different products for agriculture, forestry, urban, and home applications.  It is found in Roundup® and many other products sold in home improvement stores.

The insecticides tetrachlorvinphos, malathion, diazinon and parathion were also classified as “possibly carcinogenic to humans” (Group 2B). Tetrachlorvinphos is banned in the European Union. In the USA, it continues to be used on animals, including in pet flea collars.

Malathion is used in agriculture, public health, and residential insect control. It continues to be produced in substantial volumes throughout the world. Malathion induced DNA and chromosomal damage in humans, corroborated by studies in animals and in vitro. Bacterial mutagenesis tests were negative. Compelling evidence supported disruption of hormone pathways. Hormonal effects probably mediate rodent thyroid and mammary gland proliferation.  In the US, it is the most commonly used organophosphate insecticide.[6]
