Highly pathogenic avian influenza has infected more Michigan dairy farms only three weeks after it first spread to cattle.

The Michigan Department of Agriculture and Rural Development (MDARD) announced Friday that avian influenza was detected on three commercial farms in Ionia, Isabella and Ottawa counties. 

This brings the total number of infected Michigan dairy herds to four after avian influenza was confirmed at a Montcalm County farm in late March

An egg farm in Ionia County was also struck by the virus two weeks ago – impacting 4 million birds, federal data shows

“What is happening with HPAI in Michigan mirrors what is happening in states across the country," said Michigan Department of Agriculture and Rural Development Director Tim Boring in a statement. "This virus does not stop at county or state lines, which is why we must all be on high alert."

"This news is unfortunate and upsetting for our poultry and dairy farming families and communities, he added.

If cattle producers are noticing decreased lactation, low appetite, abnormal milk, abnormally tacky or loose faeces, and/or low fever within their herds, MDARD advises them to contact their veterinarian to determine the next appropriate steps to take before reporting.

  • Talk to a veterinarian about any animal health-related concern
  • Isolate sick animals from others
  • Minimise the number of visitors to the farm
  • Prevent contact between animals and wildlife
