    Chicken-killing Newcastle disease prompts widespread quarantines in Southern California
    About a million birds have died so far.

    With virulent Newcastle disease killing a growing number of Southern California chickens, state Veterinarian Annette Jones announced Wednesday a poultry quarantine for all of Los Angeles County and large portions of San Bernardino and Riverside counties.

    The highly contagious respiratory virus is nearly always fatal for all poultry and has most affected chickens in the current outbreak. Though the number of infections went down for several months after the disease was identified, in May, the number of cases has increased since November.

    In addition to the latest quarantines, communities in the three counties continue to have mandatory euthanasia decrees for all poultry. With past and currently planned euthanasia orders, the disease will have led to the death of 1 million birds. The numbers of birds euthanized has doubled since Jan. 25.

    “There are no human health concerns provided that any meat or eggs are cooked properly,” according to Wednesday’s announcement by the state Department of Food and Agriculture...

        Deadly chicken disease spreads to Bay Area, flocks at risk
        First-ever case of Virulent Newcastle Disease in Northern California leads to cancellation of events

        REDWOOD CITY — The live poultry show has been canceled at this spring’s San Mateo County Fair. A major Peninsula veterinary hospital is postponing all chicken appointments. And worried Bay Area backyard bird hobbyists are taking special steps to protect their flocks.

        News that a highly contagious and deadly bird virus was detected at a veterinary clinic in Redwood City on Thursday has alarmed the Bay Area’s poultry community, indicating that the dreaded Virulent Newcastle Disease has moved north from Southern California.

        The disease, first reported on May 17 in Riverside County, has led to the euthanasia of nearly 500,000 backyard and commercial birds in Southern California...
