The Woodland Park Zoo in Seattle is taking extra precautions after a confirmed case of the avian flu, according to a news release.

A red-breasted goose at the Woodland Park Zoo has died from the first suspected case of Highly Pathogenic Avian Influenza (HPAI), the zoo announced Thursday.

The infected goose, part of a rare and threatened species, was found deceased in an off-exhibit area of the zoo earlier this week.

Woodland Park Zoo is ramping up safety measures after a red-breasted goose died in what is the zoo’s first suspected case of Highly Pathogenic Avian Influenza (HPAI), or bird flu. The goose, a rare and threatened species, was found dead earlier this week, and preliminary tests received on Nov. 14 resulted in a positive result for HPAI.

Pending confirmatory testing, this would mark Woodland Park Zoo’s first case of bird flu, a viral infection carried by wild birds such as waterfowl. Bird flu is primarily spread through respiratory secretions and bird-to-bird contact, according to the zoo.

Test results confirmed that avian flu killed a rare bird at the zoo which is taking precautions to protect other birds.
