The strain, H5N2, is different from the highly pathogenic H7 virus
detected in a chicken breeder flock in Tennessee farm contracted by
U.S. food giant Tyson Foods Inc.
"Testing of the commercial turkey flock occurred after the birds
exhibited signs of depression," the U.S. Department of Agriculture
said in a report posted on the OIE website.
"The infected premises was quarantined and the turkeys will be
depopulated through controlled marketing."
The virus detected in the flock of 84,000 turkeys in Wisconsin was
of North American wild bird origin and distinct from the H5N2
virsuses detected in 2015, the USDA said.
In 2014 and 2015, during a widespread outbreak of highly pathogenic
avian flu, the United States killed nearly 50 million birds, mostly
egg-laying hens.
