Laboratory tests have confirmed that a dead swan found in the Krasnodar Territory was infected with H5 bird flu virus, but not with the N1 strain, a source in the local administration said Monday.

This is the only case of bird flu detected in the territory since 410 chickens died from the virus and 22,000 birds were culled at a local poultry farm in southern Russia.

A regional laboratory identified the lethal H5N1 virus in the dead chickens, and took steps to contain the spread.

The losses from the outbreak are estimated at 20 million rubles ($702,000).
