California Applies Pre-emptive Depletion to Control END

11/21/2018

After 176 confirmed outbreaks of "Exotic" Newcastle disease among backyard flocks in three counties in California, authorities have instituted a pre-emptive depletion program. This action localized in designated localities in the most affected counties was taken somewhat belatedly given the fact that the first cases were diagnosed in mid-May and the outbreak demonstrated progressively ascending monthly incidence rates through September.

To date there has been no report of an epidemiologic study to ascertain the source of infection or the factors contributing to dissemination and persistence in non-commercial domestic galliform and anseriform species.

There has not been any indication of lateral spread from the clusters of backyard fowl to commercial poultry.


Message from State Veterinarian Dr. Annette Jones for Residents on VND-affected areas in Compton, Muscoy, and Mira Loma

Due to progression and duration of a virulent Newcastle Disease (VND) outbreak in parts of Southern California, the State Veterinarian has ordered mandatory euthanasia of birds in neighborhoods in Compton (Los Angeles County), Muscoy (San Bernardino County), and Mira Loma/Jurupa Valley (Riverside County). Unfortunately, even if birds and flocks have previously tested negative but now happen to fall within a designated mandatory euthanasia area, the birds must be euthanized. USDA/CDFA staff will contact affected bird owners.

While this action is difficult for all involved, it MUST be done to erradicate VND. Otherwise, the disease will continue to spread and kill additional flocks.
