CHICAGO, Jan 14 (Reuters) - The U.S. Department of
Agriculture on Friday confirmed the first case of a highly
pathogenic type of avian influenza in a wild bird since 2016 in
South Carolina.
The virus, Eurasian H5 avian influenza, was found in a wild
duck that was hunted in Colleton County, in the southern part of
South Carolina, officials said.
The USDA said it is determining the exact strain of the
virus and results should be available in the next few days.
One case of the H7N3 strain of highly pathogenic avian influenza
(HPAI) was found in a commercial turkey flock in South Carolina
in 2020.
The Eurasian H5 type is considered a low risk to people but
can be dangerous for the poultry industry, South Carolina
officials said. No human infections from Eurasian H5 viruses
have occurred in the United States, they said.
The USDA advised poultry producers to review safety measures
to assure the health of their flocks. Wild birds can carry avian
flu without showing symptoms and transmit it to poultry through
their feathers or feces.
"So far we have no indication that HPAI has jumped from wild
migratory birds to poultry and we'd very much like to keep it
that way," said Michael Neault, South Carolina's state
veterinarian.
The spread of highly pathogenic avian influenza, commonly
called bird flu, in Europe and Asia late last year put poultry
producers on alert after previous outbreaks led to the culling
of tens of millions of birds. Outbreaks also often lead to trade
restrictions.
In 2015, an outbreak of avian flu led to the deaths of about
50 million U.S. chickens and turkeys.
