California v EPA: Legal challenge possible over Prop 65 labeling of herbicide glyphosate as carcinogenic

caution pesticide spraying in process

Monsanto officially lost its fight to avoid a Prop 65 warning label on its products containing glyphosate, a chemical used in the popular herbicide Roundup.

…

[T]he court’s decision raises a potential conflict between California’s Prop 65 warning label requirements and the pesticide registration and product labeling requirements under the Federal Insecticide, Fungicide, and Rodenticide Act. Pesticide product labels are intended to govern all aspects of a pesticide product, including distribution, use, application, and initial registration of the product with the U.S. Environmental Protection Agency (EPA). The EPA must approve any change or deviation made to a pesticide product label.

As recently as 2014, the EPA reaffirmed its conclusion that glyphosate is not cancerous to humans. So California’s decision to add glyphosate to the Prop 65 list raises a potential conflict for pesticide manufacturers that produce products containing glyphosate. [Editor’s note: In September of 2016, the EPA reaffirmed the safety of glyphosate to humans. Read the report here.]
