Confirmed New World screwworm infestations in the United States rose to 116 across Texas, New Mexico and Arizona, up nearly 47% from the previous Sunday; 56 cases remain active. Most cases involve livestock or pets, with detections in cattle, horses and a dog, while authorities also captured a wild screwworm fly in a New Mexico surveillance trap.
The expanding livestock parasite threat could increase cattle losses and raise animal-health and control costs, tightening effective supply and supporting cattle prices if the outbreak worsens.
