Emergency management warning 9: Newcastle disease in California in backyard 
poultry
------------------------------
Officials with the California Department of Food and Agriculture (CDFA) and 
the Animal and Plant Health Inspection Service (APHIS) are conducting an 
eradication campaign for Newcastle disease. The disease was confirmed on 1 
Oct 2002, and is restricted to backyard poultry. Clinical signs in infected 
birds include respiratory, nervous, and gastrointestinal signs. Mortality 
is up to 90 per cent of exposed birds. Commercial poultry, at this time, 
are not involved in the disease occurrence. Investigations are ongoing and 
all figures are pending final validation.

Situation update:
Number of premises positive: 81
Number of contacts: 237
Number of premises depopulated: 225
Premises waiting to be depopulated: 93
Birds depopulated to date: 21 700 (approximate)
Counties with positive flocks: Los Angeles, Riverside, San Bernardino

Operational Update:
The date of the last discovered positive case of Newcastle disease in 
California was 1 Dec 2002. Effective 13 Nov 2002, the California State 
Veterinarian has imposed a quarantine (Food and Agriculture Code Section 
9562) on the following counties:
- all of Los Angeles County
- portions of Riverside County
- portions of San Bernardino County

Effective 21 Nov 2002, APHIS has imposed a federal quarantine that 
regulates the interstate movement of poultry and poultry products from 
California's already quarantined areas.

Poultry species affected by California's quarantine are: chickens, turkeys, 
ducks, geese, grouse, partridges, pheasants, quails, Guinea fowl, peafowl 
(peacocks), doves, pigeons, swans, ratites, ratite eggs

State and federal animal health officials are conducting door-to-door 
surveys to identify fowl and other birds in the affected areas and are 
following up on all epidemiological associations. To date, depopulation, 
cleaning and disinfecting, and carcass disposal are being conducted by CDFA 
and APHIS. CDFA has closed all poultry exhibits and fairs and expositions 
within the State of California.

The Newcastle disease situation is contained and is still considered a 
single outbreak cluster within a 30 mile radius in Los Angeles County and 
along the Los Angeles/Riverside/San Bernardino County border.

Affected and exposed backyard poultry are being euthanized and 
double-bagged. Task force members are disinfecting the bags and 
transporting the carcasses to restricted landfills for burial. All 
door-to-door surveillance, along with interviews, has established that 
there have been no links to eastern states within the United States and no 
exposure to other backyard poultry in other states. Local commercial table 
egg layer birds are being closely monitored and will only be allowed to 
move intrastate under CDFA monitoring and spent-hen movements restricted to 
the day they are scheduled for processing.

New trade issues:
Effective 29 Nov 2002, China has suspended the importation of all poultry 
and poultry products originating in the State of California.

Please forward this information to your federal, State, and industry 
counterparts as necessary. If you have questions about this situation 
please contact USDA, APHIS, Veterinary Services, Emergency Programs
