The New World screwworm was eradicated from the U.S. in 1966, but was detected in Mexico in 2024, concerning leaders that it could come to Texas next.
AUSTIN, Texas — Texas Gov. Greg Abbott is directing state agencies to do more to handle what he calls a “serious threat” to livestock and cattle in the state.
Abbott has directed the Texas Animal Health Commission (TAHC) and Texas Parks and Wildlife Department (TPWD) to team up to combat New World screwworms before the species arrives in Texas.
According to state officials, the New World screwworm was eradicated from the U.S. in 1966. But in 2024, the parasite moved through Central America and established its presence in southern Mexico, leading to concern that it could end up in Texas next.
“Texas played a critical role in eradicating this pest from the United States in the 1960s and will do so again if the need arises,” Abbott said in his directive. “We stand ready to protect our land, livestock and wildlife.”
The response team will share information with stakeholders and the public, as well as coordinate the state’s preparedness and response efforts.
“Texans can be assured that staff have been actively preparing and training for a possible New World screwworm response for over a year,” TAHC Executive Director and State Veterinarian Dr. Lewis R. “Bud” Dinges said in a news release sent on Wednesday. “While we hope we don’t have to deal with the pest on our soil, joint efforts to mitigate damage and protect all commodities from NWS are ongoing and will be bolstered by this well-rounded team.”
The TPWD said the two agencies have worked together for decades in the past on disease management efforts to ensure the health and safety of livestock and wildlife in Texas.
