In a win for Monsanto Co. and U.S. farmers, California’s proposed labels warning that glyphosate is a cancer-causing chemical were suspended. Commonly sold under the moniker “Roundup”, glyphosate is the widely used herbicide in agriculture and is extensively used by consumers. In 2015, the International Agency for Research on Cancer (IARC) listed glyphosate as “probably carcinogenic,” triggering California’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Proposition 65 requires businesses to inform consumers of products that contain chemicals known to cause cancer or birth defects.
While the IARC listed glyphosate as being “probably carcinogenic,” multiple organizations including the EPA have come out against the IARC, stating there is no evidence that glyphosate is carcinogenic.
