Delaware's agriculture department says a second poultry flock is infected with the bird flu virus.
The department said today the bird flu virus found in a commercial flock of roaster-type chickens in northern Sussex County was the same H7 strain found five miles away in southern Kent County late last week.
"The Delaware Department of Agriculture found Tuesday morning that avian influenza is present on a second farm in Delaware," it said in a statement.
The H7 virus, which is not transmissible to humans, is different from the strain that has killed at least 19 people and decimated poultry stocks in 10 Asian nations.
