The Agriculture Department says turkeys at a farm in Virginia do not appear to have been exposed to the highly deadly strain of avian flu seen in other parts of the world.
State officials this week banned all live poultry sales and shows for the rest of the month in Virginia after a flock of 54,000 turkeys at a Shenandoah County farm tested positive for avian flu antibodies. West Virginia followed with a 30-day ban.
But the USDA's National Veterinary Services Laboratories has confirmed the presence of antibodies that indicate a possible prior exposure to an avian influenza virus that does not pose a threat to humans.
The department says the National Veterinary Services Laboratories will do further testing to better characterize the virus to which these birds may have been exposed.
