Exotic Newcastle Disease Prevention and Control

Information about how to prevent and control further spread of Exotic Newcastle Disease.

Be aware that this disease affects all types of birds, not just poultry, game birds and game fowl. Pet birds can get the disease and can spread the disease. Recognize also that the disease can be transmitted by people who have been contaminated. Those people will not contract the disease, but may carry it on skin and clothing. Until this outbreak has been contained, visiting among breeders and travel between establishments where birds (even pets) are housed is discouraged.

Commercial Poultry:
The only way to eradicate END from commercial poultry is by rapidly destroying all infected flocks and imposing strict quarantine and verifying controls with in-depth surveillance programs.

Poultry producers should strengthen biosecurity practices to prevent the introduction of the disease to their flocks. Biosecurity is also important to protect backyard and hobby flocks.

The following are tips on proper biosecurity practices:

  • Permit only essential workers and vehicles on the premises.
  • Provide clean clothing and disinfection facilities for employees.
  • Clean and disinfect vehicles (including tires and undercarriages) entering and leaving the premises.
  • Avoid visiting other poultry operations.
  • Maintain an “all-in, all-out” philosophy of flock management with a single-age flock.
    • Control the movement of all poultry and
      poultry products from farm to farm.
    • Do not “skim” mature birds from a flock for
      sale to a live-poultry market.
    • Clean and disinfect poultry houses between
      each lot of birds.
  • Do not keep pet birds on the farm. Employing workers who own pet birds exposes your poultry to increased disease risk.
  • Exclude vaccination crews, catching crews, and other service personnel who may have been in contact with other poultry operations within 24 hours.
  • Protect flocks from wild birds that may try to nest in poultry houses or feed with domesticated birds.
  • Control movements associated with the disposal and handling of bird carcasses, litter, and manure.
  • Take diseased birds to a diagnostic laboratory for examination.

Hobby Flocks and Pet Birds:
To prevent END from being introduced into U.S. poultry flocks, USDA's Animal and Plant Health Inspection Service (APHIS) requires that all imported birds (poultry, pet birds, birds exhibited at zoos, and ratites) be tested and quarantined for diseases before entering the country.

Birds illegally smuggled into the United States are not quarantined and tested by the U.S. Department of Agriculture (USDA) and therefore may carry the exotic Newcastle virus.

Owners of pet birds should:

  • Request certification from suppliers that birds are legally imported or are of U.S. stock, are healthy prior to shipment, and will be transported in new or thoroughly disinfected containers.
  • Maintain records of all sales and shipments of flocks.
  • Isolate all newly purchased birds for at least 30 days.
  • Restrict movement of personnel between new and old birds.

Don’t wait. Early detection can make a difference. If your birds are sick or dying, call

  • Your local veterinarian,
  • MT State Veterinarian 406-444-2043 and MT USDA APHIS Veterinary Services 406-449-2220. or
  • U.S. Department of Agriculture (USDA) Veterinary Services office to find out why. USDA operates a toll-free hotline (1-866-536-7593) with veterinarians to help you.

Approved residual disinfectants:
The Newcastle disease virus is extremely sensitive to many disinfectants. However, it is very difficult to inactivate the virus if it is in organic material, such as feces. Therefore, it is very important to use a combination of both cleaning and disinfection to get rid of this virus.

Disinfectants that will kill Newcastle Disease Virus1

    1. Phenols such as One-Stroke EnvironTM
    2. Formaldehyde
    3. Hypochlorite such as bleach
    4. Quaternary Ammonia disinfectants such as Roccal DTM
    5. Peroxygens such as Virkon STM
    6. LysolTM
