FDA Issues Emergency Use Authorization for Ointment to Prevent and Treat New World Screwworm in Multiple Species, Including Cattle, Sheep, Goats, Horses, Wild and Exotic Mammals, Wild and Pet Birds

Washington, D.C., April 24, 2026-Today, the U.S. Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) for F10 Antiseptic Barrier Ointment with Insecticide (benzalkonium chloride, polyhexanide and cypermethrin topical ointment) for the prevention and treatment of New World screwworm (NWS) infestations (myiasis).

The FDA has concluded that based on the scientific evidence available, it is reasonable to believe that F10 Antiseptic Barrier Ointment with Insecticide may be effective in the prevention and treatment of NWS myiasis in cattle, horses, minor species of hoof stock (e.g., sheep, goats, deer), raptors and other wild birds, pet birds, and captive wild, exotic, and zoo mammals, and the known and potential benefits of the product outweigh its known and potential risks. F10 Antiseptic Barrier Ointment with Insecticide may not be used in domestic dogs and cats.
