As New World screwworm infections expand across Texas and hundreds of human cases emerge in Mexico following federal funding cuts, the US Department of Agriculture and Customs and Border Protection are deploying a surveillance fleet of at least 200 Department of Homeland Security drones to track livestock infections and prevent an economic crisis.
The Cost of Cutting Animal Disease Surveillance
A few months ago, the return of screwworm infections to Texas marked the first time the parasite had reappeared in the state in decades. Foreign surveillance programs designed to stop this exact scenario in partnership with countries south of the border dissolved after losing funding. The DOGE bros decided the program simply wasn’t worth the investment. Much like the resurgence of preventable diseases such as measles, the nation is once again forced to manage a threat that had been essentially eradicated through sustained public health initiatives.
Screwworm infestations present an aggressive biological threat to agriculture. Flies deposit their eggs within the flesh of livestock, predominantly cattle, and the resulting larvae can kill the host in a matter of weeks. While the initial detections surfaced in South Texas in June, the crisis has expanded rapidly. Recent reports indicate that hundreds of Mexican citizens have also contracted infections, and the problem on the US side of the border continues to deteriorate.
Deploying the Border Patrol Drone Fleet
To combat the spread without traditional ground-level funding, the federal government has pivoted tactical hardware away from standard border security duties. The US Department of Agriculture and US Customs and Border Protection launched what the USDA described on August 10 via social media platforms including X and Facebook as “one of the most extensive animal-health surveillance operations in the country.”
This biological monitoring effort relies heavily on aerial hardware. At least 200 drones owned by the Department of Homeland Security—managed primarily through CBP—have been reassigned to scan livestock for screwworm. According to a USDA spokesperson speaking with Ars Technica, the exact number of active airframes “varies depending on availability and need.” By August 11, the USDA recorded 1,226 drone flights surveying upwards of 23,000 animals.
The Economic Calculus of Eradication
The government has directed $21 million toward operations in Mexico aimed at releasing sterile screwworm flies to suppress wild populations. Millions more are funneled into a facility at Moore Air Base in Texas, alongside a fresh $25 million commitment to construct a secondary facility in Arizona.
For perspective, the broader animal disease surveillance grant canceled under budget cuts totaled $170 million. The federal response to the current outbreak has likely already eclipsed the cost required to maintain preventative border barriers in the first place.
- Economic Exposure: USDA estimates place potential damages from an outbreak matching the scale of the 1976 Texas incident at $1.8 billion.
- Current Outbreak Scale: USDA records show 1,226 drone flights surveying over 23,000 animals by August 11.
- Infrastructure Spending: $21 million spent in Mexico, millions allocated to Moore Air Base, and $25 million for a new Arizona facility.
With nearly $2 billion in economic value tied directly to the Texas economy, the decision to defund proven eradication protocols stands as a stark lesson in fiscal mismanagement.
