Low Pathogenic Avian Influenza found in Virginia

USA: Virginia 10 July, 2007 During routine, pre-slaughter testing on July 6, 2007, officials with the Virginia Department of Agriculture and Consumer Services determined that a turkey flock (54,000 birds) in Shenandoah County tested suspicious for antibodies of presumed low pathogenic avian influenza (LPAI). Testing over the weekend by the USDA’s National Veterinary Services Laboratory (NVSL) in Ames, Iowa confirmed the presence of H5 avian influenza antibodies. NVSL has not yet identified the actual virus that caused the birds to produce the antibodies.
The farm is under quarantine and the birds are awaiting depopulation. State and federal officials and the poultry industry are increasing surveillance within a six-mile radius of the affected farm and have enhanced already strict biosecurity.
West Virginia health officials culled about 25,000 turkeys in April after a flock on a farm was struck by a strain identified as H5N2.
The Shenandoah Valley, located in Northwest Virginia, is situated between the Blue Ridge mountain range to the east and Shenandoah Mountains to the west. H7N2 LPAI virus moved from live-poultry markets to infect 197 commercial farms of turkey and broiler breeders, meat turkeys and broilers during the spring 2002 in the Shenandoah Valley of Virginia.
