Texas animal shelters face crisis as screwworm outbreak restricts pet movement

The emergence of the New World screwworm in the United States, marking the first crossing from Mexico in 60 years, has disrupted pet adoption processes across Texas. This flesh-eating parasite, which lays eggs in the wounds or mucous membranes of mammals, poses a significant threat to the $113 billion beef industry and has led federal officials to restrict cattle movements across the border.

Because the insect can also infect domestic pets, 44 states have implemented restrictions on moving animals from infested areas of Texas to other regions. This has caused significant overcrowding in Texas animal shelters that rely on transporting animals to the Northeast or Great Lakes regions to manage population levels.

Shelters, such as the Gulf Coast Humane Society in Corpus Christi, have reported sudden spikes in animal populations due to these movement restrictions. Without the ability to transfer animals, some organizations warn that they may face increased euthanasia rates to manage the surplus of dogs and cats.
