Monsanto ‐ Roundup Herbicide
California’s Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced in 2015 that they planned to list glyphosate, the active ingredient in Monsanto’s Roundup herbicide, as a chemical known to cause cancer under Proposition 65, which requires consumer products with potential cancer‐causing ingredients to bear warning labels.
Monsanto filed formal comments with OEHHA saying the plan to list glyphosate as a carcinogen should be withdrawn. When the agency didn’t give in, Monsanto took it a step further and filed a lawsuit against OEHHA in January 2016 to stop the glyphosate/cancer classification. OEHHA filed a motion to dismiss the lawsuit, and a Fresno, California superior court judge ruled on their behalf in February 2017.
California regulators stated that glyphosate will appear on the state’s list of cancerous chemicals beginning 7 July 2017 which means new labels may be appearing within the next year in California that include a cancer warning on Roundup and other glyphosate‐containing weed killers, including Ortho Groundclear, KleenUp, AquaMaster, Sharpshooter, StartUp, Touchdown Total, Traxion, Vector and Vantage Plus Max II, and others.
