The ban threatens Texas cattle exports amid rising producer costs and operational disruptions for U.S. beef suppliers.
U.S. officials confirmed a second screwworm case, prompting Canada to bar Texas livestock imports. The outbreak adds pressure to the already shrinking U.S. cattle herd, increasing emergency measures and costs for producers.
Texas livestock exporters face lost revenue from the cross-border ban, while major beef producers may encounter operational challenges. The U.S. cattle herd has declined in recent years, amplifying concerns over supply constraints.
Authorities stated the food supply remains unaffected, as screwworms do not contaminate beef products.
