Nearly 5 million domestic birds affected by deadly avian flu in Nebraska this year

OMAHA — Twelve cases of a highly contagious and deadly avian flu have now been confirmed in Nebraska this year. 

The disease has affected nearly 5 million chickens, gamebirds and other poultry in the state, in both commercial and backyard flocks.

The Nebraska Department of Agriculture, working with the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture, announced the most recent case Oct. 21, affecting a commercial flock of 33,500 gamebirds in York County. 

HPAI, or highly pathogenic avian influenza, is a virus that spreads easily among birds through nasal and eye secretions, as well as manure. It can spread in different ways from flock to flock, including by wild birds, through contact with infected poultry, equipment or the clothing and shoes of caretakers.

Wild birds can carry the virus without getting sick, while domesticated birds can become very sick, said state experts.

The infections have occurred in two waves this year. The first began in mid-March and lasted until late April. 

The second began in mid-September and has affected two commercial flocks and two backyard flocks since then, as recently as last week.

Before this year, Nebraska hadn’t seen a confirmed HPAI case since 2015. 

Roger Dudley, veterinarian for the State Department of Agriculture, said in a release that the York County flock was “humanely depopulated” and will be disposed of in an approved manner.

Nebraska officials will establish a 6.2-mile control zone around the affected area, as is national policy. Those in the area are advised of the signs and symptoms of HPAI and of the need to notify the state about sick or dying poultry.

According to the Centers for Disease Control and Prevention, the risk of the flu being transmitted from birds to people is low. Among the symptoms of the disease are:

  • Decreased water consumption.
  • Lack of energy and appetite.
  • Decreased egg production or soft-shelled, misshapen eggs.
  • Nasal discharge, coughing or sneezing.
  • Incoordination.
  • Diarrhea.
  • Sudden death even without other symptoms.

For more information or to report sick birds call (402) 471-2351. Early detection is vital in preventing the spread of the disease, officials said.
