California will label Monsanto’s Roundup herbicide as a product that is “known to cause cancer.”
California environment officials issued a notice of intent to change the label last week, making the state the first to require such a label for Roundup.
The label change follows a move by the International Agency for Research on Cancer classifying glyphosate as “probably carcinogenic to humans” earlier this year.
Glyphosate is the main ingredient in Roundup. Monsanto maintains that the product is safe to use.
The listing does not restrict use or sales of the specified substances, and the public is allowed to submit comments regarding the proposal through October 5th.
In 2013, Monsanto received approval from the Environmental Protection Agency for glyphosate, claiming the product is health and environment safe.
