Emergency Management Warning 93:
Exotic Newcastle Disease Confirmed in the United
States
Exotic Newcastle disease (END) was confirmed on October 1, 2002, in the
State of California, and has now spread beyond backyard flocks to affect
22 commercial operations in California. On January 16, 2003, END was also
confirmed in a backyard flock in the State of Nevada. A backyard flock was
confirmed with END on February 4, 2003, in the State of Arizona. On April
9, 2003, END was also in backyard fowl in Texas. Clinical signs in
infected birds include respiratory, nervous, and gastrointestinal signs.
Mortality is up to 90% of exposed birds. Investigations are on-going and
all figures are pending final validation. Animal and Plant Health
Inspection Service (APHIS) personnel and other federal government
personnel are working with the States to consider additional resources to
meet the labor demands at the Task Forces. APHIS has implemented a plan
for enhanced national END surveillance.

Operational Update
• Effective January 7, 2003, APHIS imposed a federal quarantine that
regulates the interstate movement of all species of birds and poultry
products from Imperial, Los Angeles, Orange, Riverside, San Bernardino,
San Diego, Santa Barbara, and Ventura Counties, CA.
• Effective
January 17, 2003, APHIS imposed a federal quarantine that regulates the
interstate movement of all species of birds and poultry products from
Clark and a portion of Nye County, NV.
• Effective February 10,
2003, APHIS imposed a federal quarantine that regulates the interstate
movement of all species of birds and poultry products from all of La Paz
and Yuma Counties and a portion of Mohave County, AZ.
• Effective
May 14, 2003, Mohave and Yuma Counties, AZ, Nye County, NV, and portions
of La Paz County, AZ, and Clark County, NV, were removed from the list of
quarantined areas because of exotic Newcastle disease.
• Effective
April 10, 2003, APHIS imposed a federal quarantine that regulates the
interstate movement of all species of birds and poultry products from all
of El Paso and Hudspeth Counties, TX, and Dona Ana, Luna, and Otero
Counties, NM. The federal quarantine was placed on counties beyond the
infected county due to their proximity to the infected county.
• A
quarantine was placed on a portion of New Mexico because of its proximity
to the infected area in the State of Texas
• Effective May 14,
2003, APHIS imposed a federal quarantine that regulates the interstate
movement of all species of birds and poultry products from a portion of
Kern County, CA.
• The U.S. Department of Agriculture (USDA) has
declared an extraordinary emergency for the States of Arizona, California,
Nevada, Texas, and New Mexico. These declarations allow USDA to apply
federal authority within Arizona, California, Nevada, New Mexico, and
Texas.
• Currently there are still 18 commercial premises in the
State of California affected by END. The breakdown of the commercial
premises involved is as follows: 4 premises in Riverside County (3
infected and 1 contact), 5 premises in San Diego County (5 infected), and
9 premises in San Bernardino County (9 infected).
• DNA sequencing
analysis confirms that the Texas END outbreak was caused by a separate
introduction of virus and not by movement of virus from the affected areas
in California, Nevada, or Arizona. Intensified surveillance in El Paso
County, TX, and the surrounding areas has yielded no further positive
cases, suggesting that our early detection and swift response has worked
well to contain and eliminate this outbreak.
Outreach Activities
• END Task Force personnel passed out educational materials at their
booth during a Mother's Day celebration in Bakersfield, CA. The sponsor of
the celebration is a local Spanish-language radio station.
• In
conjunction with the Task Force, the Texas Animal Health Commission in
Austin continues to send out information packets to stakeholder
organizations; most recently, the commission has mailed materials to feed
stores, veterinary clinics and pet stores.
