Market Impact

The confirmed spread of the New World screwworm, particularly into Mexico and additional counties in United States — Texas, poses a significant threat to the U.S. livestock industry.

Event Summary

The New World screwworm, a flesh-eating fly larva, has spread in the United States with five confirmed cases across United States — Texas and Mexico. The U.S. Department of Agriculture (USDA) is actively working to eradicate the pest, which poses a severe threat to cattle, wildlife, and pets. The USDA plans to invest over $1 billion, including building a $750 million fly factory in United States — Texas, to increase sterile fly production as a long-term solution. However, United States — Texas Agriculture Commissioner Sidney Miller has criticized the federal response as too slow, advocating for a poison bait solution. The outbreak has led to temporary import restrictions on livestock from United States — Texas by Canada and movement restrictions by Georgia, raising concerns for the U.S. beef industry already facing supply tightness.
