Pennsylvania enacts quarantine amid screwworm concerns
Tap title to read story
Pennsylvania issued a quarantine this month after Agriculture Secretary Russell Redding announced restrictions to limit animal movement and tighten biosecurity against New World screwworm. State officials said the order, effective in June, aims to prevent infected livestock from entering and to mandate veterinary clearance for animals moving from affected states after the first U.S. detection on June 3.
Harrisburg officials and the USDA outlined immediate measures this week including movement controls, veterinary examinations for transported animals, and heightened surveillance; Pennsylvania reported no confirmed cases. Federal planning for large-scale sterile-male release programs and state biosecurity guidance seeks to protect roughly 1.6 million cattle and mitigate economic risk as investigators track confirmed cases across Texas and New Mexico.
