FDA authorizes wound spray to help protect Texas livestock and wildlife from New World screwworm

Texas ranchers and wildlife managers now have a new tool to help protect animals from New World screwworm, as the parasitic fly continues to spread in the state. The U.S. Food and Drug Administration has issued an Emergency Use Authorization for CLiK Extra, a wound spray that can help prevent New World screwworm infestations in livestock and several species of wildlife. The authorization comes as the U.S. responds to an outbreak that has resulted in 45 confirmed New World screwworm infestations, according to the latest federal data. The FDA said CLiK Extra may be effective in preventing New World screwworm infestations, known as myiasis, when used as authorized. “Today's emergency use authorization provides a new tool for preventing the spread of New World screwworm infestations,” Acting FDA Commissioner Kyle Diamantas said.
