(Salem, OR) -- A quarantine in Lane County to help limit the spread of bird flu has been lifted. The quarantine was put into effect on May 17th after bird flu was detected in a backyard flock. The quarantine prevented birds in a six mile radius from being transported. The infected birds were euthanized. No new cases have been found in the area. The U.S. Department of Agriculture approved the state's request to lift the quarantine. Agriculture officials urge people with backyards flocks to take steps that will keep them separated from wild birds.
