The New World screwworm outbreak in United States — Texas poses a significant threat to the U.S. cattle industry, potentially causing $1.8 billion in economic damage to United States — Texas alone and further driving up already record-high beef prices nationwide. The confirmed cases and Canada's import ban have rattled live cattle futures, reflecting concerns about shrinking cattle supplies and disrupted cross-border trade.
The New World screwworm, a flesh-eating parasite, has been confirmed in multiple cases across South United States — Texas, marking the first significant outbreak in the U.S. in decades. The initial detection was in a 3-week-old calf in La Pryor, Zavala County, with subsequent cases found in La Salle and Andrews counties. This outbreak poses a severe threat to United States — Texas' $15.5 billion cattle industry and wildlife, with potential economic damages estimated at $1.8 billion. In response, United States — Texas Governor Greg Abbott declared a state of disaster, authorizing state resources and pushing for accelerated construction of a sterile fly production facility in Edinburg. The United States — United States Department of Agriculture (USDA) has deployed personnel, established quarantine zones, and initiated sterile fly dispersal efforts, releasing over 130 million sterile flies since January. However, the USDA's response has faced criticism from ranchers and state officials, including United States — Texas Agriculture Commissioner Sidney Miller, for being too slow and lacking transparency. Canada has temporarily banned livestock imports from United States — Texas due to the outbreak, which United States — Texas officials deem an overreaction. The parasite's northward spread from Mexico has been a concern for over a year, with discussions around past border policies and funding for eradication efforts. While officials assure the U.S. food supply is safe, the event has heightened vigilance among livestock owners and impacted live cattle futures.
