Overview of virulent Newcastle Disease:
Virulent Newcastle Disease is a highly contagious and deadly virus in birds; the virus is found in respiratory discharges and feces. Clinical signs in birds include:
- Nasal discharge
- Green watery diarrhea
- Neck twisting
- Muscle tremors
- Decreased egg production
- Swelling around eyes and neck
- Sudden death
It is essential that all poultry owners follow good biosecurity practices to help protect their birds from infectious diseases such as Newcastle. These include simple steps like:
- Washing hands before and after entering a poultry area
- Using dedicated shoes and clothes when caring for birds and do not to use/wear those clothes/shoes in other areas.
- Cleaning and disinfecting tires and equipment before moving them off the property
- Not borrowing or buying "used" poultry equipment
- Ensuring waterers and feeders are kept clean
- Limiting contact with wild birds
Virulent Newcastle disease is not a food safety concern. No human cases of Newcastle disease have ever occurred from eating poultry products. Properly cooked poultry products are safe to eat. In very rare instances people working directly with sick birds can become infected. Symptoms are usually very mild, and limited to conjunctivitis and/or influenza-like symptoms. Infection is easily prevented by using standard personal protective equipment.

Reporting and Necropsy Services
|In addition to practicing good biosecurity, all bird owners should report sick birds or unusual bird deaths through California’s Sick Bird Hotline at 866-922-BIRD (2473).|
Sick or dead backyard birds can be submitted to CAHFS laboratories for post-mortem examination ($20 plus shipping and handling). Information on this program can be found on the CAHFS website. The test requested would be a "Necropsy exam - Backyard birds" (Test Code 10843).
