Efforts Intensify to Combat New World Screwworm Outbreak in Texas

In Austin, Texas, concerns are mounting over the spread of the New World screwworm after recent cases were confirmed. This parasitic fly lays larvae, which consume living tissue, primarily affecting livestock and other animals. On Monday, officials reported a case in a goat in Gillespie County, Texas, adding to two earlier reports—a calf in La Salle County, Texas, and a dog in Lea County, New Mexico.

State and federal officials are intensifying measures to control the parasite’s spread. Dr. Lewis R. “Bud” Dinges, Executive Director of the Texas Animal Health Commission, stated that teams are actively engaged in affected areas. They conduct animal surveillance, establish checkpoints, collaborate with landowners for sterile fly release, conduct both ground and aerial releases of sterile flies, and provide education on pest prevention.

The cattle and beef industry in Texas is already experiencing stress from high prices and limited supply. At County Line Barbecue, a significant rise in brisket costs has necessitated menu adjustments. Owner Skeeter Miller noted how creating diverse platters helps manage these costs. According to the U.S. Department of Agriculture, brisket wholesale prices have risen significantly—from around $2.40-$3.00 per pound in 2021 to $5.75-$7.00 per pound in 2025.

Emily Williams Knight, President and CEO of the Texas Restaurant Association, highlighted the slow replenishment of beef herds compared to previous shortages like the chicken and egg crises. Demand for beef has grown, but supply struggles to match, increasing pressure on the restaurant industry. Knight emphasized that beef holds economic and cultural significance in Texas, where barbecue is a cultural staple.

The confirmed screwworm cases in Texas add uncertainty to the strained beef supply chain. Veteran operators like Miller acknowledge the challenge, having endured other industry crises such as mad cow disease and bird flu. Miller reassures customers that quality beef remains a priority. “We want to ensure patrons have a great experience,” he said.

Officials at Monday’s briefing encouraged immediate reporting of suspected screwworm cases among ranchers and livestock owners. Prompt reporting is crucial, as resources like sterile flies are limited and necessary for halting the spread efficiently.
