The USDA and partners are intensifying controls on the screwworm threat, including releasing sterile screwworms, deploying 8,000 border fly traps, testing tens of thousands of samples, and planning new facilities and a factory in Texas and Mexico to breed sterile flies.

A 12-mile quarantine zone has been established around the detected case in Texas, with sterile flies released within the zone and ongoing heavy releases of more than four million flies weekly in the region.

Funding for eradication efforts is substantial, including hundreds of millions for a Texas factory project and a cross-border facility conversion in Mexico to boost containment and release capacity.

Outbreaks threaten cattle and poultry production and could influence beef prices amid broader inflation concerns, though officials stress there is no direct food-safety risk from the illness.

The screwworm pest endangers livestock, wildlife, and pets, with rare risks to humans, potentially impacting cattle health and beef prices if outbreaks worsen.

The pest does not infest meat or foods directly, but poses a major economic threat to livestock and could affect beef prices if the outbreak grows.

Historically, an outbreak in 2016 affected deer in the Florida Keys but was contained by the next spring.

Historically eradicated from North and Central America, the screwworm remains present in South America and has moved north in recent years, raising concern among farmers and scientists.

Officials report no other detections in the United States beyond the Texas case, and treated cases can recover, with no foodborne infestation indicated.

Residents in Zavala County are urged to inspect pets and livestock for signs like draining wounds or maggots and to contact authorities if infection is suspected.

Resurgence began around 2023 due to pandemic-related program disruptions and other factors; outbreaks have spread across Central America and Mexico, with a travel-related human case detected before the U.S. calf case.

The discovery marks a re-emergence after the species was eradicated in the U.S. in the 1960s, signaling new surveillance and containment challenges for authorities.
