A strain of highly pathogenic bird flu has been detected in Michigan at a non-commercial backyard bird farm in Kalamazoo County, federal authorities said Thursday.
Samples from the herd were tested at the Michigan State University Veterinary Diagnostic Laboratory and confirmed by USDA Animal and Plant Health Inspection Service laboratories in Ames, Iowa.
State officials have quarantined the Kalamazoo County site and all 34 birds on this property “will be depopulated to prevent the spread of disease,” the USDA said, noting that birds from this flock will not will not enter the food system.
This is the first case of bird flu in Michigan, said USDA spokeswoman Lyndsay Cole. It’s unclear how he reached the barnyard herd, she said.
The virus strain is potentially lethal to commercial poultry.
The bird flu cases are among the latest in the United States that has put farms that raise turkeys and chickens for meat and eggs on high alert, fearing a repeat of a 2015 bird flu outbreak that killed 50 million birds in 15 states and cost the federal government. nearly $1 billion.
Avian influenza has also been detected in commercial turkey flocks in southern Indiana, a commercial broiler flock in Kentucky, a commercial poultry flock in Delaware, a backyard flock of birds of mixed species in northern Virginia, as well as New York and Maine, both to a single noncommercial backyard flock.
The US Centers for Disease Control say recent bird flu detections do not present an immediate public health concern. No human cases of these viruses have been detected in the United States
Yes, the case in backyard poultry in Kalamazoo County is the first case of HPAI in Michigan. There were 34 birds in the flock and they were depopulated.
APHIS is working closely with state animal health officials to conduct epidemiological testing to trace the origins of these cases. Importantly, this is the same H5 clade of the Eurasian lineage that was introduced to the United States in 2014/2015 by wild birds, as well as the same that was found in wild birds in the Atlantic flyway in January.
