KERRVILLE, Texas (AP) — Two more cases of the New World screwworm have been confirmed in Texas, demonstrating the difficulty of stopping the spread of a pest that could potentially devastate the nation’s cattle industry, the U.S. Department of Agriculture announced Monday.

The screwworm is actually a fly, which produces a larva that eats live flesh instead of dead material. Females lay their eggs in open wounds of any warm-blooded animal such as cattle, but wildlife, pets and occasionally even humans can be infested.

The USDA said the new cases were found in a calf and a dog, hundreds of miles apart in La Salle and Andrews counties. That brings the total number of confirmed cases to four. The screwworm was first discovered in a 3-week-old calf last week, and a second case was found only miles away in a young calf.

“While we address these instances that require immediate attention, and continue to sample suspected cases, we are simultaneously working to eradicate the pest entirely,” Dudley Hoskins, the USDA’s marketing and regulatory undersecretary, said in a statement.
