Two More Texas Screwworm Cases Confirmed as USDA Escalates Emergency Response

The United States Department of Agriculture has confirmed two additional New World Screwworm infections in Texas, intensifying fears that the flesh-eating parasite could once again threaten America’s livestock industry after being absent from the United States for nearly six decades.

The newly confirmed cases involve a calf in La Salle County and a dog in Andrews County, hundreds of miles apart, bringing the total confirmed U.S. cases to four.

Federal officials say the discovery demonstrates how difficult the dangerous parasite may be to contain as it spreads northward from Mexico.

Flesh-Eating Parasite Expands in Texas

The New World Screwworm is not actually a worm, but the larval stage of the Cochliomyia hominivorax fly.

Unlike ordinary flies that feed on dead tissue, female screwworm flies lay eggs inside open wounds or body openings of living warm-blooded animals.

Once hatched, the larvae aggressively burrow into living flesh using hook-like mouthparts, causing horrific tissue destruction, infection, and, in severe cases, death.

The USDA confirmed the latest infected dog had reportedly recently traveled from Mexico, where outbreaks have continued expanding northward.

Officials say the parasite threatens:

  • Cattle
  • Horses
  • Wildlife
  • Pets
  • Goats
  • Deer
  • Humans in rare cases

Before eradication efforts succeeded in the 1960s, the screwworm caused massive economic damage to the U.S. cattle industry every year.

USDA Launches Aggressive Counterattack

Federal authorities say they are moving aggressively to stop the spread.

The USDA and Texas Animal Health Commission currently have more than 75 personnel directly involved in response operations, while hundreds more support laboratory testing, logistics, aerial operations, and surveillance nationwide.

Agriculture officials are now releasing approximately 10 million sterile flies weekly across Texas and northern Mexico.

The sterile male flies mate with wild females, which only reproduce once during their lifespan. Because the sterile males produce nonviable eggs, the population gradually collapses over time.

USDA has also activated its sterile fly dispersal facility at Moore Air Base in Edinburg, Texas.

Under Secretary Dudley Hoskins stated:

“While we address these instances that require immediate attention, and continue to sample suspected cases, we are simultaneously working to eradicate the pest entirely.”

Quarantines and Surveillance Intensify

For each confirmed case, officials are implementing strict containment measures outlined in the USDA’s New World Screwworm Response Playbook.

These include:

  • 20-kilometer quarantine zones
  • Movement restrictions for animals
  • Expanded trapping operations
  • Increased wildlife surveillance
  • Enhanced veterinary outreach

Officials are urging livestock owners and pet owners to immediately inspect animals for:

  • Draining wounds
  • Visible maggots or eggs
  • Unusual lesions
  • Excessive licking or biting
  • Restlessness or pain

Anyone spotting suspicious infestations is instructed to immediately contact veterinarians or state agricultural authorities.

Political Tensions Rise Over Response

The crisis has also sparked political friction inside Texas.

Agriculture Secretary Brooke Rollins rejected criticism from Texas Agriculture Commissioner Sid Miller, who accused federal agencies of moving too slowly.

Rollins defended the Trump administration’s response, saying officials are moving at “Trump speed” and investing over a billion dollars to stop the outbreak before it becomes entrenched.

She also emphasized that the U.S. food supply remains safe.

According to USDA officials, screwworms do not infest processed meat, fruits, or vegetables, and infected animals would never enter the food chain under federal inspection procedures.

Prophetic Context: Pestilence and the Fragility of Nations

The growing screwworm outbreak comes amid rising global concerns over pestilence, agricultural instability, food security, and biological threats.

Luke 21:11 (NASB 1995) warns:

“And there will be great earthquakes, and in various places plagues and famines; and there will be terrors and great signs from heaven.”

Throughout Scripture, agricultural devastation and pest outbreaks often symbolized both judgment and the fragility of human systems apart from God.

As modern governments struggle to contain increasingly complex biological threats, many Christians view these events as reminders of how quickly food systems, economies, and national stability can become vulnerable.

The world’s dependence on centralized systems continues to reveal dangerous weaknesses.

Strategic Implications

The discovery of multiple screwworm cases hundreds of miles apart raises serious concerns about how widespread the infestation may already be.

If containment efforts fail, the economic consequences for America’s cattle industry could become enormous.

Texas alone generates approximately $15 billion annually from cattle production, making it one of the most critical agricultural regions in the nation.

Federal authorities are now racing to stop the parasite before it establishes permanent breeding populations inside the United States once again.
