The return of screwworm comes after the Musk-led Department of Government Efficiency, launched by the Trump administration, last year cut funding for a project dedicated to monitoring and containing New World screwworm in Central America.
The funding was axed days before the U.S. ended a temporary suspension of cattle imports from Mexico, meaning livestock was allowed to cross the border without any of the monitoring previously funded by the U.S. Agency of International Development (USAID).
Agriculture officials and cattle industry leaders raised alarm about the cuts at the time and, for the last several months, pleaded with the government to step in as they monitored screwworm infections moving north through Mexico-but they were ignored, Texas Agriculture Commissioner Sid Miller told NBC News.

"Instead of using every available tool, USDA moved too slowly and relied solely on a partial solution that takes years to fully implement," Miller said, adding a plea for President Donald Trump to "throw every available federal resource at this threat before it becomes a full-blown agricultural disaster."
What Is Screwworm?
New World screwworm is a fly that lays its eggs in open wounds and body openings of warm-blooded animals. Infestations start when a female fly lays eggs on open wounds-wounds as small as a tick bite can attract a female fly to lay her eggs-or other parts of the body in live animals. Eggs hatch into maggots that feed on the living flesh for about 7 days before the larvae drop to the ground, burrow into the soil, and emerge as adult screwworm flies-starting the cycle again. Most infestations occur in animals, but they can occur in people. The most recent human case in the U.S. was reported in Maryland last year in a traveler who'd returned from El Salvador. The person recovered.
Key Background
The United States eradicated screwworm in the 1960s through a massive sterile fly program, but outbreaks in Mexico and Central America have raised concerns about the parasite moving north again. The eradication was the result of multiple sterile fly programs across the south that cost roughly $42 million in the mid 1960s, the equivalent of about $452 million today. Despite the programs' success, there have been stand-alone instances of screwworm since, including an isolated outbreak in Texas in 1976 that cost ranches an estimated $452 per head of cattle in today's dollars, totaling $732 million. Those losses came from cattle death, weight loss and hide damage and the cost of surveillance and treatment. Evidence suggests screwworm outbreaks of the past did drive the price of beef higher, though not necessarily in a dramatic nationwide surge, because ranchers in the 1950s and 60s were working in a much stronger industry with higher herd numbers.The U.S. cattle herd had dropped to 86.2 million head of cattle and calves on U.S. farms as of Jan. 1, the lowest number of cattle in America since 1951. In May, the USDA said it predicts beef production will decline by 0.9 percent to 25.310 billion pounds in 2027 and said cattle prices are "projected to reach new highs as supplies remain limited." The average price of ground beef has risen from $3.95 in December of 2020 to $6.89 in April, according to the Federal Reserve.
Big Number
$1.8 billion. That's how much economic damage could be caused by another outbreak on the scale of the Texas incident in 1976, according to USDA estimates.
What To Watch For
How the officials try to contain the spread. The Canadian Food Inspection Agency has barred livestock that originated in or passed through Texas within 21 days from crossing the border, CNBC reported, and Florida separately enacted emergency rules restricting warm-blooded animal imports from infested zones, according to CBS News. The USDA is spending $750 million on a new Texas facility capable of producing roughly 300 million sterile screwworms per week, but it won't be operational until at least 2027, per NBC News. Officials from Texas and the USDA are taking steps to "contain and eradicate" screwworm, the agency said, including implementing cattle quarantines, movement controls and surveillance within a roughly 12 mile area of the infected calf; trapping flies along the border; and releasing millions of sterile male New World screwworm flies in the region. There are 75 personnel actively responding on the ground to the Texas screwworm outbreak, with hundreds more providing laboratory, logistics and air operations support nationwide, according to the USD
