HARRISBURG, Pa. — The Pennsylvania Department of Agriculture has issued a quarantine order restricting the movement of certain animals into the state following confirmed cases of New World screwworm in Texas and New Mexico.
While no cases have been reported in Pennsylvania, state officials said the precautionary measure is intended to prevent the spread of the destructive pest, which poses a serious threat to livestock, pets and wildlife.
New World screwworm is a parasitic fly whose larvae infest living tissue, causing severe injury and, in some cases, death. The pest primarily affects livestock but can also impact pets, wildlife, birds and, in rare instances, humans.
Under the order, susceptible animals entering Pennsylvania from affected areas must meet enhanced health requirements, including veterinary inspections and proper certification. The regulations also include preventive measures designed to reduce the likelihood of the pest entering the commonwealth through animal transport.
Agriculture officials are urging farmers, veterinarians and animal owners to remain vigilant and report any unusual wounds or signs of infestation. Early detection is critical to limiting the spread and minimizing potential economic and animal health impacts.
Additional details, including the full quarantine order and guidance on identifying and preventing New World screwworm, are available through the Pennsylvania Department of Agriculture.
