USDA says Michigan bird flu case no risk to humans
WASHINGTON (Reuters) – The U.S. Departments of Agriculture
and Interior said on Monday routine surveillance found the
presence of H5 and N1 avian influenza subtypes in samples from
two wild mute swans in Michigan.
But testing ruled out the possibility of it being the
highly pathogenic H5N1 strain that has spread through birds in
Asia, Europe and Africa.
Test results so far indicate this is low pathogenicity
avian influenza, which poses no threat to human health.
More extensive test results will be available in about two
weeks time, U.S. officials said.
