A second case of the New World screwworm, a dangerous flesh-eating parasite, has been confirmed in Texas by the U.S. Department of Agriculture. This detection has led Canada to implement temporary restrictions on livestock imports from affected U.S. areas to prevent the spread of the pest.
Officials assure the U.S. food supply remains safe, as the screwworm does not infest food products and affected animals would be intercepted.

The U.S. Department of Agriculture (USDA) has confirmed a second case of the New World screwworm, a parasitic fly whose larvae feed on living flesh, in Texas. The discovery in Zavala County, approximately 5.6 miles from the initial detection, has prompted immediate action from international trading partners concerned about potential spread.
The affected animal was a one-month-old calf. While additional samples from the surrounding area have tested negative, officials are reinforcing containment measures. The New World screwworm poses a significant threat to livestock, wildlife, pets, and, in rare cases, humans, as its larvae can cause fatal wounds if left untreated.
In response to the confirmed cases, Canada's Food Inspection Agency (CFIA) has announced temporary restrictions on livestock imports from affected U.S. regions. This measure specifically prohibits the entry of animals, including horses, that have originated in or been present in Texas within the 21 days prior to crossing the border.
Federal and state officials are emphasizing that the new case was identified within an established movement-control zone, where efforts to suppress the pest population through the release of sterile insects are already underway. The USDA assures the public that the U.S. food supply remains safe, as screwworms do not infest food products and any affected animals would be identified and prevented from entering commerce.
"USDA has not wasted any time in this fight, we have defeated New World screwworm before, and we will do it again," stated Dudley Hoskins, the agency's Under Secretary for Marketing and Regulatory Programs. Texas Farm Bureau President Russell Boening urged continued vigilance among livestock owners, highlighting the importance of prompt surveillance and reporting for swift eradication.
