Virulent Newcastle Disease Update from State Veterinarian Dr. Annette Jones

Ongoing surveillance and testing in the virulent Newcastle disease (VND) incident in Southern California has resulted in the detection of a new case on August 14 at a retail feed store in western San Bernardino County.

This is the first detection of VND since June 4.  Staff members from the California Department of Food and Agriculture (CDFA) and the U.S. Department of Agriculture (USDA) discovered the infected birds during a routine biosecurity check. Infected and exposed birds have been euthanized and the store has been temporarily closed while an investigation is under way.  

We are moving quickly to determine the origin of disease and working with the store to identify any customers who may have purchased infected birds and products like feed, equipment, or anything else that could carry infection. Our priority is to stop the spread of the virus and eradicate the disease, and while we’ve made significant progress, this case is instructive for all bird owners in Southern California to remain aware of VND signs, practice good biosecurity, don’t move birds, and report any sick birds immediately to the Sick Bird Hotline 866-922-2473.


The regional quarantine is still in effect (see map here). For a list of virulent Newcastle disease cases since the outbreak began in May 2018, visit the USDA VND website.


Attention: The United States Postal Service (USPS) is not allowing shipments of live birds (all) or hatching/embryonated eggs into or out of zip codes 90000-93599 in California. For more information:
