The Center for Biological Diversity said EPA rarely requires cancer warnings, even on ingredients it agrees are tied to the disease.

An environmental group urged EPA on Wednesday to require cancer warnings on all pesticides containing ingredients the agency already links to the disease — a mandate that would go far beyond current practice.

In an emergency petition, the Center for Biological Diversity said most active pesticide ingredients EPA has linked to cancer don’t carry a required label disclosing the risk.

The agency “consistently fails to warn the public about known cancer risks associated with pesticides,” the CBD said in the petition.
