Ruling rejects Monsanto's latest attempt to keep consumers in the dark about the hazards of glyphosate

A California Appellate Court has sided with the State of California and Center for Food Safety (CFS) in affirming that Monsanto's glyphosate pesticide can be listed as a probable carcinogen under Proposition 65. Monsanto's lawsuit challenged the 2015 announcement by California's Office of Environmental Health Hazard Assessment (OEHHA) that it intended to list glyphosate, the active ingredient in Monsanto's herbicide, Roundup, under California's landmark Proposition 65.

Proposition 65 requires notification and labelling of all chemicals known to cause cancer, birth defects or other reproductive harm, and prohibits their discharge into drinking waters of the state. CFS intervened in the case, defending the listing of glyphosate as a carcinogen and the public's right to know when it is being exposed to cancer-causing chemicals.

"This is a huge win for all Californians — and a huge loss for Monsanto — as it upholds our right to protect ourselves and our environment from unnecessary and unwanted exposure to the dangerous chemical, glyphosate," said Adam Keats, senior attorney at CFS.

Glyphosate is a broad spectrum herbicide that is widely used in agriculture, parks, home gardens, and residential landscapes. It is the most heavily used pesticide in the world, in large part due to the proliferation of Monsanto's genetically engineered Roundup Ready crops that are resistant to glyphosate.

In 2015, the International Agency for Research on Cancer (IARC) of the World Health Organisation (WHO) concluded that glyphosate is "probably carcinogenic." California subsequently issued the notice of intent to list glyphosate as a Proposition 65 chemical based on the IARC finding.

Under Proposition 65, no person in the course of doing business may knowingly or intentionally expose any individual to a chemical known to the state to cause cancer or reproductive toxicity without first giving a clear and reasonable warning. The discharge of such chemical into a source of drinking water is prohibited. With today's court ruling, these protections will now be required for glyphosate products.

"All California consumers have the right to know that glyphosate is considered a probable carcinogen, and Proposition 65 ensures that the public obtains that knowledge," said Rebecca Spector, West Coast Director at Center for Food Safety. "We are pleased that the California Appellate Court prevented Monsanto's attempt to keep the public in the dark about potential hazards from their products."

CFS, a public interest organisation dedicated to protecting human health and the environment from the hazards of industrial agriculture, has been heavily involved with regulation of glyphosate.
