FDA Authorizes Emergency Screwworm Treatment for Cats and Dogs as Texas Outbreak Response Expands
Federal regulators have authorized emergency use of nitenpyram as a treatment option for cats and dogs affected by New World screwworm infestations, broadening the federal response to the growing Texas outbreak.
The authorization comes as federal and state officials continue efforts to contain confirmed screwworm infections that have primarily affected livestock. While public attention has focused on cattle and potential economic losses, veterinarians have long warned that companion animals can also be vulnerable when open wounds attract screwworm flies.
The FDA action is designed to ensure treatment options are available should veterinarians encounter cases involving household pets. Nitenpyram is commonly used in veterinary medicine for parasite control, and the emergency authorization provides additional flexibility in responding to screwworm infestations.

The announcement quickly drew attention from veterinary professionals, animal shelters, and pet owners. Educational posts and veterinary guidance circulated widely online, focusing on wound monitoring, early intervention, and recognizing potential symptoms.
The move also highlights how the outbreak has evolved beyond agriculture. Ranchers remain concerned about livestock impacts and cattle supplies, but pet owners are now increasingly engaged in the story as awareness grows regarding risks to companion animals.
Federal officials continue to stress that containment remains the primary objective. The authorization nevertheless reflects a broader preparedness effort aimed at ensuring treatment resources are available across multiple categories of animals if additional cases emerge.
