  • All treated human food or animal feed crops will be destroyed unless a tolerance greater than residues anticipated from the treatment or exemption from the requirement of a tolerance has been obtained from the Environmental Protection Agency (EPA).
  • “Destroyed" means rendered unusable for food or feed or used for research purposes only.
  • Any adverse environmental effects will be immediately reported to the department.
