Pa. issues quarantine order after New World screwworm cases confirmed in U.S.

Key Points:

• The Pennsylvania Department of Agriculture has issued a quarantine order effective June 9 to restrict movement of susceptible domestic animals from areas affected by New World screwworm, aiming to protect the state's livestock, pets, wildlife, and agricultural economy.
• The first U.S. case of New World screwworm was confirmed on June 3 in Texas, with additional cases reported in Texas and New Mexico, but no cases have been reported in Pennsylvania.
• New World screwworm larvae feed on living tissue, causing severe wounds that can be life-threatening if untreated; animal owners and producers are urged to inspect animals regularly and seek veterinary care if infestation is suspected.
• The quarantine order requires veterinary inspections, animal health certification, and preventive measures to reduce the risk of pest introduction through transported animals, with coordination ongoing among state health and environmental agencies.
• Residents are advised to watch for signs of infestation such as unusual irritation, head shaking, decay odor, and maggots in wounds, and to report suspected cases immediately to the Pennsylvania Department of Agriculture.
