New World Screwworms, a destructive parasitic larvae that burrow into animal flesh and cause fatal infections, have reportedly been discovered in South Texas after decades of containment in Central America.
The parasites, sometimes called "flying piranha," hatch from eggs laid in wounds and create gaping ulcers, often killing infected animals.
A resurgence in the United States could devastate cattle ranches, disrupt supply chains, and spike beef prices.
Trump administration cuts to public agricultural programs, combined with pandemic disruptions, allowed the infestation to spread northward. Texas officials across both parties are responding urgently.
Republican Agriculture Commissioner Sid Miller called for direct presidential intervention and immediate deployment of eradication resources.
Democratic Senate nominee James Talarico emphasized the need for fully staffed USDA oversight to provide ranchers guidance and protect herds.
Republican state Rep. Don McLaughlin (R-TX) pledged coordinated action across local, state, and federal agencies.
