The U.S. Department of Agriculture on Monday confirmed two additional cases of New ‌World screwworm in Texas, ​involving a calf in La Salle County ⁠and a dog in ​Andrews County. The USDA added that epidemiological investigations ⁠are ongoing for both cases.

New World screwworm is a serious pest ‌that threatens livestock, pets, ​wildlife, and, in ‌rare cases, people, the ‌USDA said. The larvae burrow into the living tissue of animals, causing ⁠severe wounds, ‌animal suffering, ⁠and significant economic losses.

A second case ⁠of ⁠the flesh-eating screwworm parasite was confirmed in ‌Texas by the USDA on Friday, emerging just miles from ‌where ​the first ‌U.S. detection in decades was reported last week.
