VIRULENT NEWCASTLE DISEASE ALERT




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.

For more information please refer to: Virulent Newcastle Disease FAQs or call the Sick Bird Hotline at 866-922-2473



Secure Food Supply (SFS) Plans

Commercial producers are encouraged to enforce biosecurity plans and develop Secure Food Supply (SFS) Plans, which are designed to provide business continuity in the face of a foreign animal disease outbreak.

Virulent Newcastle Disease (VND)


Virulent Newcastle disease (VND), formerly known as Exotic Newcastle Disease, is a serious, highly contagious viral disease that can affect poultry and other birds. In rare cases, humans that have exposure to infected birds may get eye inflammation or mild fever-like symptoms. These signs generally resolve without treatment, however, medical care should be sought if symptoms persist. Infection is easily prevented by using standard personal protective equipment. 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.

The virus is found in respiratory discharges and feces and may cause high rates of sickness and death in susceptible birds. For poultry, chickens are most susceptible and ducks and geese are the least susceptible. Mortality rates for Psittacine birds (parrots) can range from zero up to 75%. Certain parrots, especially Amazon parrots, can shed VND virus intermittently in excess of one year. Other birds may be infected, but may not show any symptoms and may still be able to spread the disease. Once VND is introduced into domestic avian populations, subsequent spread is normally caused by domestic bird-to-bird contact or through contact with contaminated people, feed or equipment. Other types of Newcastle disease known as lentogenic and mesogenic are less virulent and may cause mild symptoms or none at all.

There is no effective cure for virulent Newcastle Disease. It is important that all commercial and non-commercial poultry owners maintain effective barriers to mitigate the risk of VND. Biosecurity tips for commercial poultry owners can be found here. For Backyard and non-commercial poultry owners, biosecurity tips can be found here.

2018 Virulent Newcastle Disease Outbreak in Backyard Poultry in Southern California (More/Less)


Week of October 26–November 1, 2018: Additional Cases of Virulent Newcastle Disease in Los Angeles and Riverside Counties
Bird owners in Southern California are responding to outreach provided over the past several days related to virulent Newcastle disease (VND), and have reported sick birds. Samples from the flocks, which experienced increased mortality, were tested at the California Animal Health & Food Safety Laboratory System (CAHFS). The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Services (APHIS) National Veterinary Services Laboratories (NVSL) in Ames, Iowa, confirms all findings. Six additional cases of virulent Newcastle disease have been confirmed in backyard chickens in Los Angeles County and Riverside County in California. For a list of cases visit the USDA website at: https://www.aphis.usda.gov/animalhealth/vnd

To date, there have been no VND detections in commercial poultry. The presence of the 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 rare cases, humans that have exposure to infected birds may get eye inflammation or mild fever-like symptoms. Infection is easily prevented by using standard personal protective equipment.

The California Department of Food and Agriculture (CDFA) and United States Department of Agriculture (USDA) want to remind bird owners about the need for biosecurity to help protect their birds from VND and other infectious diseases. These include simple steps like washing hands and scrubbing boots before and after entering a poultry area; cleaning and disinfecting tires and equipment before moving them off the property; and isolating any birds returning from shows for 30 days before placing them with the rest of the flock. 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).

Samples from the flocks, which experienced increased mortality, were tested at the California Animal Health & Food Safety Laboratory System (CAHFS). The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Services (APHIS) National Veterinary Services Laboratories (NVSL) in Ames, Iowa, confirms all findings. Virulent Newcastle disease has been confirmed in one flock of backyard birds and one additional presumptive positive case also in backyard birds – both in San Bernardino County, California. CDFA is working closely with APHIS to respond to these findings, and is investigating any potential links between these cases and the case recently identified in Los Angeles County. Associated premises investigation and area disease control and surveillance is underway.

May 18, 2018: Virulent Newcastle Disease Confirmed in a Backyard Chicken Flock in Los Angeles County
The California Department of Food and Agriculture (CDFA) has detected virulent Newcastle disease in a small flock of backyard exhibition chickens in Los Angeles County. The detection has been confirmed by the United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS). This is the first case of virulent Newcastle disease, previously referred to as exotic Newcastle disease, in the U.S. since 2003.

CDFA is working with federal and local partners as well as poultry owners to respond to the finding. State officials have quarantined potentially exposed birds and are testing for the disease.

2002-2003 Exotic Newcastle Disease Outbreak in Backyard and Commercial Poultry in Southern California and Surrounding States (More/Less)

The 2002-03 END outbreak, originally confirmed in backyard poultry in Southern California, spread to commercial poultry operations in California and backyard poultry in Arizona, Nevada and Texas.  The Governor of California declared a State of Emergency, the Secretary of the United States Department of Agriculture (USDA) declared an Extraordinary Emergency, and local emergencies were declared in San Diego, Riverside, Los Angeles, and San Bernardino Counties.  A USDA and the California Department of Food and Agriculture (CDFA) Task Force was formed that involved over 7,000 individuals rotating in and out over the course of the outbreak.  Trade restrictions resulting from the disease had negative impacts on California and U.S. poultry and egg producers.  The outbreak, from discovery to eradication, lasted eleven months.  The outbreak response led to the depopulation of 3.16 million birds at a cost of $161 million.


1971 Exotic Newcastle Disease Outbreak in Commercial Poultry in Southern California (More/Less)


Outbreaks of END severely affect the poultry industry. In 1971, a major outbreak occurred in commercial poultry flocks in Southern California. In all, 1,341 infected flocks were identified and almost 12 million birds were destroyed. The eradication program cost taxpayers $56 million, severely disrupted the operations of many producers and increased the prices of poultry and poultry products to consumers.
