Screwworm parasite reemerges in U.S., threatening cattle industry amid debate over causes and containment
SUMMARY
The New World screwworm, a parasitic fly eradicated from North America decades ago, has reappeared in Texas and New Mexico, prompting a federal response using sterile fly releases. The USDA estimates over $1 billion in containment costs, including a new facility to produce 300 million sterile flies weekly. While all sources agree on the threat to livestock and the control strategy, there is divergence on the cause: one source emphasizes political blame between administrations, while another points to illegal cattle smuggling by organized crime in Central America as the root driver. Experts warn that without addressing underlying regional issues, the parasite may continue to spread.
