📣Today, U.S. Secretary of Agriculture Brooke Rollins provided an update on the ongoing response to the New World Screwworm, a flesh-eating parasite that can affect cattle, horses, sheep, goats, wildlife, pets, and, in rare cases, people.
🐄Federal officials recently confirmed several cases in Texas and New Mexico, prompting increased surveillance and response efforts.
🏜 While there are currently no reported cases in Arizona, livestock owners play an important role in early detection and prevention.
What ranchers can do:
• Inspect livestock regularly, especially animals with cuts, wounds, branding
sites, or recent procedures.
• Pay close attention to newborn animals and healing wounds.
• Watch for unusual wound drainage, foul odors, maggots, or wounds that
appear to worsen instead of heal.
• Promptly report suspicious cases to your veterinarian or the Arizona
Department of Agriculture.
• Maintain good wound care and fly control practices.
Protecting livestock starts with awareness. Early detection remains one of the most effective tools for preventing the spread of this pest.
