FDA Authorizes New Medications to Combat Spreading Screwworm Infestations Along U.S.-Mexico Border
The FDA has authorized additional medications to prevent and treat New World screwworm infestations, a flesh-eating parasite, which is spreading along the U.S.-Mexico border.
Tampa St. Petersburg, FL, August 15, 2026 —
The U.S. Food and Drug Administration (FDA) has authorized the use of additional medications aimed at preventing and treating New World screwworm infestations. This development comes as the parasitic infection, known for consuming living flesh, continues to spread along the border region between the United States and Mexico.
New World screwworms are a type of fly larva that feed on living mammalian tissue. The parasite’s spread raises concerns for both animal and, in rare instances, human health. While primarily affecting animals, the increasing presence of the infestation in border areas has prompted regulatory action to control its expansion.
The authorization by the FDA allows for broader access to and utilization of specific medications designed to combat the parasite. Details regarding the specific types of medications authorized or the quantities were not immediately available. The agency’s move is intended to provide more tools to veterinarians, public health officials, and potentially livestock owners in affected areas.
The U.S. Department of Agriculture (USDA) has also been involved in monitoring and managing the screwworm situation. Efforts to control the spread typically involve a multi-faceted approach, including surveillance, treatment of infected animals, and potentially the release of sterile insects to disrupt the parasite’s life cycle.
The exact timeline for the increased spread or the specific areas most affected by the current outbreak were not detailed in the information provided. However, the FDA’s action signifies an elevated response to a growing concern in the region. Further information regarding the implementation of these new medications and the ongoing containment strategies is expected from relevant federal agencies.
