Branch Hillsdale St. Joseph Community Health Agency has been notified by the Michigan Department of Health and Human Services that a Trumpeter Swan collected by Michigan Department of Natural Resources tested positive for HPAI H5.
The swan was collected in Hillsdale County.
There are no additional cases identified at this time, nor has there been identified transmission to backyard or commercial flocks in the area. No human illnesses have been identified. There is not a food safety concern.
Health officer Rebecca Burns said she encourages residents to continue monitoring birds for illness and practicing bio-security measures to protect their backyard flocks of poultry.
There may be no routine signs of illness, Burns said, adding that sudden death of a bird is a major indicator of HPAI.
