California to List Monsanto’s Roundup Ingredient as Carcinogen

According to an announcement by the state’s Office of Environmental Health Hazard Assessment (OEHHA), Glyphosate, the active ingredient in Monsanto’s Roundup weed killer product, will be added to California’s list of chemicals that’s known to cause cancer effective July 7.

Monsanto vowed to continue its fight against the latest designation and stated it was “unwarranted on the basis of science and the law.” The designation is a setback for Monsanto, a company that has faced an increasing amount of litigation over the use of the chemical since 2015, when WHO’s International Agency for Research on Cancer rated Glyphosate as “probably carcinogenic”.

Glyphosate is not the only herbicide under major scrutiny. Dicamba, another active ingredient used in Monsanto products, is under scrutiny in the state of Arkansas. Last week, the Arkansas State Plant Board voted for an emergency rule banning sale and use of dicamba. Pastureland is exempt from the emergency dicamba-use ban.

Nathan Donley, a scientist at the Center for Biological Diversity, said “California‚Äôs decision makes it the national leader in protecting people from cancer-causing pesticides”. According to the state branch of the EPA, Glyphosate is the most widely used herbicide in California. It is sprayed on more than 200 crops across 4 million acres of land in California.
