U.S.D.A. / A.P.H.I.S. Emergency Management Warning Issued October 3, 2002
Newcastle Disease (ND) Confirmed in California
ND has been confirmed in game fowl in the Los Angeles, CA area.ND is a
contagious and fatal viral disease affecting domestic, wild, and caged
birds. This disease in poultry is characterized by respiratory signs
accompanied by nervous manifestations, gastrointestinal lesions, and
swelling of the head.
On September 27, 2002, the National Veterinary Services Laboratory
(NVSL) received tissue specimens from game fowl suffering high (90%)
mortality; the owner lost 200 game fowl in 4-5 days. On September 29,
2002, NVSL isolated an avian paramyxovirus type-1 from the tissues. On
October 1, 2002, NVSL confirmed that the virus has multiple basic amino
acids at the fusion protein cleavage activation site, a sequence
compatible with that of mesogenic/velogenic pathotypes. Reisolation of
the virus from the original specimen is in progress.
The State of California has disease response teams in the field and are
placing hold orders on all involved premises. Currently, there are six
premises, three with clinical signs, involved in the ND situation in
California. The premises are located in Compton, Lancaster, Norco, and
Pico Rivers, CA, and a shipment that was intercepted in route to
Ontario, CA. Two premises have already been depopulated and a third
premises is waiting depopulation. None of the six premises involved are
adjacent to any commercial poultry facilities. Preliminary
epidemiological findings do not indicate that ND has spread to any other
areas outside of the areas stated.
The Animal and Plant Health Inspection Service is working with the
California Department of Food and Agriculture (CDFA) to assess the
extent of the spread and to contact bird owners about the disease.
Bird owners are urged to contact their local or State veterinarian
immediately to report birds showing suspicious clinical signs.
States are urged to notify their industry and veterinary counterparts to
be vigilant for clinical signs consistent with ND.

CDFA will issue a press release today notifying the public of the ND
