Texas animal health authorities are intensifying efforts to prevent the spread of screwworm infestations, a serious livestock threat that can cause severe wounds and even death in animals if left untreated.
The Texas Animal Health Commission (TAHC) has announced an expanded surveillance program, increased field inspections, and stronger coordination with ranchers, veterinarians, and border agencies. The move comes as part of ongoing vigilance against the pest, which historically caused significant economic losses before being eradicated from the U.S. decades ago.
Screwworms, the larvae of a parasitic fly, invade open wounds in warm-blooded animals. If not detected early, infestations can spread quickly and impact both animal welfare and livestock productivity.
“Prevention is our strongest defense,” said a TAHC spokesperson. “By working closely with producers and maintaining strict monitoring at entry points, we aim to keep Texas livestock safe and the state free of screwworms.”
Officials are urging livestock owners to promptly report any suspicious wounds or maggot infestations and to follow best practices for animal care and wound treatment. The program also includes public awareness campaigns and cooperation with neighboring states and Mexico to prevent cross-border introductions.
