The USDA has established a regional quarantine in Lane County, Ore., to curb the spread of highly pathogenic avian influenza, which has been accelrating throughout the Pacific Northwest.

The quarantine for all avian species and vehicle traffic involved with avian species has been issued for an area extending a minimum of 6.2 miles around the infected property.

A map of the outbreak areas in Linn and Lane Counties and the quarantine area in Lane County is available online. People may enter their address to determine whether they are included in the quarantine area.

This regional quarantine will prevent the movement of poultry from within this area for a period of time sufficient to allow state and federal officials to conduct surveillance within the quarantine area to ensure no additional cases of HPAI exist. The quarantine also applies to importation of all birds from states where a state or federal quarantined area due to HPAI exists.

Organizers of events involving birds must immediately inform the Oregon State Veterinarian of any scheduled events. Additionally, they must share the new rules with the event exhibitors and vendors.

Temporary emergency rules were filed with the Oregon Secretary of State on May 19. Visit the avian influenza webpage here.

The quarantine comes after several Canada goose goslings collected from Alton Baker Park in Eugene tested positive for HPAI, and a larger outbreak is suspected as more sick and dead waterfowl have been observed at the park. A red-tailed hawk from Eugene and an osprey collected from Dorena Reservoir (east of Cottage Grove) May 10 have also tested positive.

Recent cases have also been found in Linn County, Ore., in seven counties in Washington and five in Idaho.

Outbreaks of the H5N1 bird flu have devastated commercial poultry operations in the Midwest this year, killing over 37 million chickens and turkeys. HPAI has yet to show up in commercial flocks in the West, but the disease has been found in backyard flocks throughout the region, including in Colorado, Wyoming, Montana and Utah.
