During the week of May 10-16, the United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service confirmed 2 additional premises as positive for virulent Newcastle disease in Riverside County, California. APHIS also completed sequencing on 6 additional samples that had been collected previously, so those will also be added to the list of positive premises.

Affected flocks are quickly euthanized. Together, these actions will help us prevent additional disease spread and eradicate the disease more quickly.  

USDA is announcing new premises confirmed with vND in California weekly. Samples are still being tested and confirmed as they are identified.  If there is a finding in a new state, USDA will issue an announcement immediately. A complete list of confirmed positive premises is available on our website at www.aphis.usda.gov/animalhealth/vnd.

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. Infection is easily prevented by using standard personal protective equipment. 

Samples from the flocks were tested at the California Animal Health & Food Safety Laboratory System (CAHFS). The APHIS National Veterinary Services Laboratories in Ames, Iowa, confirms all findings. APHIS is working closely with the California Department of Food and Agriculture to respond to these findings and to conduct an epidemiological investigation. Federal and State partners are also conducting additional surveillance and testing in the area.

In addition to practicing good biosecurity, all bird owners should report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or USDA’s toll-free number at 1-866-536-7593.
