On July 7, the state of California will add glyphosate, the main ingredient in Roundup weed killer, to its list of chemicals known to cause cancer, but the maker of the product, Monsanto, is vowing to fight it out in court.
When a chemical is listed as being a known carcinogen, companies selling the product in California must add warning labels to their packaging. Monsanto has filed an appeal, saying the chemical doesn't cause cancer and labels would harm business, The Associated Press reports. "This is not the final step in the process," Monsanto Vice President of Global Strategy Scott Partridge said. "We will continue to aggressively challenge this improper decision."
The chemical is sprayed on 250 types of crops in California, and has no color or smell.
