FDA Greenlights Emergency Wound Spray as Screwworm Threat Looms for U.S. Livestock

F-10 Wound Spray can now be used for livestock and other animals as officials monitor the ongoing New World Screwworm outbreak in Mexico.

NASHVILLE, TENN. (RFD NEWS) — The U.S. Food and Drug Administration (FDA) issued an emergency use authorization for a wound spray to help combat potential outbreaks of New World Screwworm as the current outbreak just south of the U.S. Border in Mexico enters its second year.

The agency states that F-10 Wound Spray, an antiseptic spray manufactured in South Africa, can now be used on cattle, horses, birds, and other animals. The product contains ingredients designed to protect wounds and kill parasites.

Officials emphasize that the spray is not fully approved for this use, but the emergency authorization allows it to be used as outbreaks of the screwworm threaten livestock and wildlife.
