Information received on 17 November 2003 from Dr Peter Fernandez, Associate Administrator, Animal and Plant Health Inspection Service, United States Department of Agriculture (USDA), Washington, DC:

The exotic strain of Newcastle disease virus detected primarily in backyard flocks in the States of California(1), Nevada(2), Arizona(3) and Texas(4) has been completely eradicated.

The confirmation of this exotic strain of Newcastle disease virus triggered an emergency response resulting in the depopulation of almost 4.5 million birds.

During the epizootic, 21 commercial operations and 911 backyard establishments were confirmed positive. The last infected commercial operation was found on 26 March 2003 and the last infected backyard establishment was found on 31 May 2003. During the peak of the eradication activities, over 19,000 establishments were quarantined and over 2,500 of these establishments were depopulated.

With the successful eradication of the virus, effective 16 September 2003, all States and Federal quarantines in all areas were officially lifted.

Enhanced surveillance in commercial flocks as well as targeted surveillance in backyard flocks has not detected any further evidence of the virus. Surveillance continues and efforts have now been shifted to prevention and mitigation through outreach and education programmes.

The virus has been completely stamped out and, in accordance with Article 2.1.15.3 of the Terrestrial Animal Health Code, there are no further infected zones. All restrictive measures in relation to Newcastle disease in the United States of America have therefore been lifted.
