The U.S. Department of Agriculture confirmed June 3 that a case of the New World screwworm, a parasitic fly, was detected on a cattle ranch in South Texas.
The overview: The case marks the first domestic detection of screwworm in a decade and the first Texas case in approximately 50 years. The flesh-eating parasite is a threat to the state’s $15.5 billion cattle industry.
Zooming in: No additional infestations have been identified, U.S. Secretary of Agriculture Brooke Rollins told reporters. Federal and state officials have emphasized that they do not anticipate issues with the food supply chain, as the screwworm only targets live animals and does not infest meat, fruit or vegetables.
However, experts have warned that a larger, prolonged screwworm outbreak could cause a spike in beef prices.
A widespread infestation is estimated to cost Texas at least $1.8 billion per year in damages, according to a USDA analysis of a 1976 screwworm outbreak. Texas cattle, sheep and goat producers would face about $732 million in annual losses.
