Oregon biologists track ‘concerning’ bird flu outbreak impacting California seal pups

An ODFW spokesperson said the agency will track cases, although they're expected to remain near California's Año Nuevo State Park.
PORTLAND, Ore. (
KOIN) — Oregon scientists are tracking marine mammals after several animals in a neighboring coastline tested positive for a severe disease.
Last week, the U.S. Department of Agriculture’s National Veterinary Services Laboratory
confirmed the presence of highly pathogenic avian influenza in seven elephant seal pups located in California’s Año Nuevo State Park.
Meghan Dugan, a spokesperson for the Oregon Department of Fish & Wildlife’s Marine Program and West Region, told KOIN 6 the California outbreak is “concerning.”
“Oregon has a small breeding population of northern elephant seals in the state at Cape Arago, on the south coast,” Dugan said. “We hope and expect these H5N1 cases to remain fairly localized to Ano Nuevo State Park in California, as most of the older animals have already moved away from the area prior to clinical signs developing in younger animals. Nevertheless, biologists and stranding network personnel will be tracking any abnormal developments in our marine mammals in the state.”
Dugan noted this is the second time H5N1 has caused illness or death in marine mammals along the Pacific coastline, with the first incident happening in 2023. The
National Oceanic and Atmospheric Administration revealed three adult harbor seals in Washington’s Puget Sound had tested positive for the strain that September.

Dugan has also urged Oregonians to call the West Coast Region Stranding Hotline at 866-767-6114, and keep their distance, if they see deceased, injured or sick mammals along the coast.
