No signs of emerging New World screwworm threat in WA

Washington state officials are breathing easy as the re-emergence of the New World screwworm, a parasitic fly that's a menace to livestock and pets, hasn't shown signs of spreading there. The fly can't survive in colder climates, and Washington has bolstered its inspection protocols to prevent any potential infestations. This development is significant because the New World screwworm was eradicated in the U.S. back in 1968, and its return would pose a serious threat to agriculture and pet health nationwide.
