A federal court has told the Environmental Protection Agency to revisit its registration of glyphosate.
The U.S. Ninth Circuit Court of Appeals on June 17 remanded part of the EPA’s registration decision to the agency for further consideration.
Glyphosate will remain legal to use while EPA does its review.
The Natural Resources Defense Council and other organizations that brought the lawsuit argued the EPA had not adequately considered whether glyphosate causes cancer.
The EPA, like national pesticide regulators in other countries, has ruled that Roundup’s main ingredient is unlikely to be a cancer-causing agent, though a 2015 ruling from a World Health Organization panel called the herbicide a probable carcinogen.
Glyphosate maker Bayer said it believes the EPA will continue to conclude that the widely used herbicide can be handled safely and is not a carcinogen.
