Screwworm Infestation Confirmed in Florida Livestock, Triggering Emergency Response Measures
ORLANDO, Florida — A confirmed screwworm infestation has been detected among livestock in central Florida, prompting state and federal agricultural officials to enact emergency containment protocols, officials announced Tuesday, February 25, 2025.
The identification of the parasitic larvae, known scientifically as Cochliomyia hominivorax, was made by the Florida Department of Agriculture and Consumer Services. The screwworm, which feeds on living tissue, poses a significant threat to warm-blooded animals, including cattle and pets. A coordinated response has involved the U.S. Department of Agriculture, which has established a quarantine zone to prevent further spread. The exact location of the infestation is being limited to specific ranch properties.
The outbreak has raised immediate concerns for the livestock industry, as the screwworm can cause severe wounds and lead to animal deaths if untreated. Authorities have deployed sterile fly release programs, a technique historically used to eradicate the pest, along with mandatory inspections for all animal movements within the affected region.
No human cases have been reported, officials confirmed. Recommendations for livestock owners include inspecting animals daily and applying approved wound treatments. The federal government is monitoring the situation closely, with further updates expected within 72 hours.
