Highly pathogenic avian influenza found in 3 more Michigan counties
The highly pathogenic virus has been detected in dairy herds in Ionia, Isabella and Ottawa counties.
An outbreak of bird flu is affecting dairy cows in the U.S.
Three new dairy herds in Michigan have been affected by avian influenza, according to the state Department of Agriculture and Rural Development.
The highly pathogenic virus has been detected in dairy herds in Ionia, Isabella and Ottawa counties — bringing the total number of outbreaks in Michigan to four.
The first herd to test positive was in Montcalm County on March 29 — marking the first time the virus has appeared in Michigan cattle. MDARD also confirmed an outbreak at a commercial poultry facility in Ionia County.
Michigan’s state veterinarian says the virus originated in cows that were transported from Texas, where several outbreaks have been popping up in cattle populations across the Lone Star State.
While the virus can be fatal among poultry, veterinarians say it doesn’t affect cows the same and, with care, they can recover.
The risk to humans remains low.
The department’s director says the virus does not stop at county or state lines and asks all producers and farm owners to be on high alert.
They are urged to tighten up biosecurity measures to avoid spreading the virus between groups of farm animals, or from wild birds which can carry it.
The virus can be spread directly between animals, or indirectly through items such as feed, equipment,and the clothing and shoes of caretakers.
Officials say the commercial milk and egg supplies remain safe, and there is no increased risk to consumer health.
