Confirmatory tests being conduced on Pennsylvania wild bird samples

2 September, 2006

The U.S. Departments of Agriculture and Interior today announced that the presence of the H5 and N1 avian influenza subtypes in samples from wild mallard ducks in Pennsylvania. Testing has ruled out the possibility of this being the highly pathogenic H5N1 strain that has spread through birds in Asia, Europe and Africa. Test results thus far indicate this is low pathogenic avian influenza (LPAI), which poses no threat to human health.
The ducks were sampled August 28, 2006 in Crawford County, Pennsylvania. The ducks were showing no signs of sickness, which also suggests this is LPAI. The samples were taken by Pennsylvania Game Commission personnel under a cooperative agreement with USDA, as part of an expanded wild bird monitoring program. The Departments of Agriculture and Interior are working collaboratively with States to sample wild birds throughout the U.S. for the presence of highly pathogenic avian influenza (HPAI).
