Exotic New Castle Disease in California 2002-2003
- Exotic New Castle: Term used for virulent strains of a virus that
dramatically affect poultry.
- (Not a public health concern)
- The event started for CDFA/USDA October 1, 2002: Backyard chickens in
Compton, Montebello (Los Angeles County), and Norco (Riverside County)
- State was declared free September 16, 2003 !!!
A Key to Success: Interagency Cooperation and the Use of
ICS
- Approximately 11 Federal Agencies
- 18 California State Agencies
- 6 Nevada State Agencies
- 3 Arizona State Agencies
- Texas and New Mexico State Agencies
- Numerous county, city, and local groups
- Numerous private stake holders
- Colorado River Indian Tribe
- Secretaria de Fomento Agropecuario, Baja, Mexico
- SAGARPA
Freedom Declared Sept. 16, 2003
- First detected almost year before
- Most of the activity was in California but disease was detected in 4
states
- To prevent a repeat episode, work continues in both Southern and Northern
California
Resources and Personnel
- CDFA commitment to response prior to approval of funding sources (fall
months)
- USDA declaration of extraordinary emergency! (Jan. 2003)
- (1,800+ at one time)
- Federal Employees – 5,352
- State and Local Employees – 2,338 (California, Nevada, Arizona, New
Mexico, Texas)
- Most returned for multiple rotations with some returning as many as 12
times
Exotic Newcastle Disease
- Initially spread in backyard pet and hobby chicken populations
- Challenges:
- Urban Setting
- Cultural Barriers
- Defining Population at Risk
- Disease Detection (Reporting)
- Disease Cross-cut Allied Industries
- (Pet and Exotic Birds, Ostriches, Poultry, Processors, Distributors,
Feed Mills, Rendering)
- Disposal!!
Key Factors Driving the END Epidemic in Southern
California
- Illegally Imported Birds
- A Population of Infected Pet Birds and/or Game Fowl
- Co-mingling of Pet Birds and Backyard Birds
- A Large Susceptible Population of Backyard Birds
- A Highly Mobile Population of Backyard Owners and Birds
- Within State and Out of State
- Feral and Free-Ranging Birds
- Employee Interaction Between Backyard Birds and Commercial Poultry
- Commercial Industry Marketing Channels
Pet and Hobby - Backyard Poultry
- Premises surveyed > 300,000
- 75,910 identified with poultry in target areas of California
- Cumulative premises quarantined = 19,056
- Cumulative positive or dangerous contact = 2,671
- Cumulative birds depopulated = 149,247
Commercial Poultry
- Commercial premises identified = 806
- 154 within the Regional Quarantine
- 652 in Northern California
- Last positive commercial premises = 3/26/03
- Infected premises = 21
- Dangerous contacts = 1
- Birds depopulated = 3,021,815
- Spent hens destroyed = 1,321,969
Disposal Challenges
- Safety concerns
- Can it be spread to people?
- Can it infect other birds or animals?
- Can chemicals used for disinfection be a problem?
- Communicating with task force employees, other government employees and
the public regarding safety
- Key materials that had to be destroyed/disposed of:
- Commercial
- Backyard
- Birds
- Contaminated materials and equipment!
Disposal Challenges
- Multiple cities/locations required a way to minimize disposal contracts
- Rapid decomposition
- Communication regarding safety
- Overdressing at the landfill sends the wrong message
Disposal Challenges
- Old USDA disposal rules-needed new thinking (depth and burying material)
- (answer: Innovative video presenting modern coverage techniques and
biosecurity at the land-fill (Riverside Co.))
- Solid waste vs. fluids (egg disposal)
- Identifying agencies and others that needed to be involved
- LEAs
- Regional Water Boards…. And how to contact
- OES can bring groups together..if they know who to bring together!
- Establishing local government working groups-very helpful during the
crisis
Challenges we faced and overcame with the help of others
- Timing of disposal (weekends/late days)
- Classification/ communication with others about status:
- Hazardous vs. nonhazardous material
- Transportation
- C/D at landfills
- Emergency declaration lessons
- What may be a crisis for one group may not be for another without the
use of tools like declarations
Take Away Messages for CDFA/USDA
- We had a Learning Curve regarding
- Routes of disposal and their relative challenges especially in an urban
environment
- Plans need to be revisited because of changes in Laws, Reg.s and public
opinion
- USDA burial guidelines as an example
- Periodic interaction between Animal Health Agencies and Environmental
Agencies can only HELP us in knowing what each others challenges are and how
we can overcome them together
