Immediate Release: July 9, 2024

Highly Pathogenic Avian Influenza Detected in Gratiot County Dairy Herd


Today, Michigan Department of Agriculture and Rural Development (MDARD) Director Tim Boring announced the detection of highly pathogenic avian influenza (HPAI) in another dairy herd from Gratiot County, bringing the total number of affected dairy herds in Michigan to 26. Testing through the Michigan State University Veterinary Diagnostic Laboratory initially detected this case. Samples have been sent to the U.S. Department of Agriculture's (USDA) National Veterinary Services Laboratories for additional confirmatory testing.

Regardless of the species, biosecurity remains the best tool available to combat HPAI. On May 1, 2024, Director Boring issued the Determination of Extraordinary Emergency HPAI Risk Reduction and Response Order (HRRRO). In addition to other protocols, the order requires all dairy operations in Michigan to adopt enhanced biosecurity measures, collectively reducing the risk of introducing this virus on to farms. The order also prohibits the exhibition of all lactating dairy cattle, and those in the last two months of pregnancy, until there are no new cases of HPAI in Michigan dairy cattle for at least 60 consecutive days. No dairy cattle of any age from an infected premises may be exhibited until further notice.

In addition to these requirements, following a few key steps can also be fundamental to protecting the health and vitality of Michigan's dairy cattle:
  • Delay or stop incoming or returning animals from herds with unknown or suspect health status.
  • Isolate all animals that are new or returning to your farm.
  • Monitor the health of your animals daily.
  • Contact your veterinarian if there are ever any animal health-related concerns or if you would like to develop a secure food supply plan.
  • Sick animals should have dedicated equipment and be cared for after tending to healthy animals first.
  • Clothing, footwear, and equipment worn/used around sick animals should not be worn/used around other animals until they are cleaned and disinfected. Use an EPA-registered disinfectant effective against avian influenza.
  • Do not share tools, equipment, trailers, etc. with other farms.
  • Clean and disinfect the interiors of trailers used to haul animals from other operations.
  • Limit non-essential visitors to your farm.
  • If individuals have recently been on a poultry farm, they should not visit a dairy operation, and vice versa.
  • Require or provide clean clothing and footwear to those entering your farm.
  • Use hand-washing stations and provide gloves to those working on your farm.
As part of the disease response, MDARD is working with the herd veterinarian to monitor the health of the animals and conduct trace investigations. Additionally, MDARD and various federal and state partners continue to offer personal protective equipment at the request of dairy operations. The department continues diligently working with local, state, and federal partners to quickly respond to reports of HPAI to mitigate the spread of the disease and provide outreach.

"Current Strains in Cattle continue to be associated with bird migration and the Strain of the Virus seen in wild birds...."

Michigan Department of Agriculture meets to discuss bird flu
Published: Feb. 6, 2025 at 10:28 PM EST| Updated: 8 hours ago​


LANSING, Mich. (WILX) - The state Department of Agriculture and Rural Development met to discuss the state’s response to bird flu cases on Thursday.

The department says they are taking a multifaceted approach to mitigating the bird flu. This includes taking part in the USDA’s milk testing strategy program, which monitors for bird flu in milk supply and dairy herds.

“We’ve seen a couple of recovering dairy herds, but we haven’t seen any active infections going on in Michigan dairy farms. So those strains of the virus that we’ve seen across Michigan here continue to be associated with wild bird migration and the strain of the virus seen in wild birds,” an official said,” said MDARD Director Tim Boring.

The Centers for Disease Control and Prevention says it believes the current risk to humans from bird flu viruses remains low.

Two domestic cats infected with H5N1 virus in Michigan
Max Reinhart The Detroit News
18 hours ago

Experts are urging cat owners to refrain from feeding their pets raw meat or unpasteurized milk after the bird flu virus was detected in two indoor domestic cats in Michigan.

The Michigan State University Veterinary Diagnostic Laboratory said cats appear to be highly susceptible to the HPAI A(H5N1) strain of avian influenza and "increased vigilance is needed to both protect cats from infection and to better understand virus transmission between animal species."

The two cats that were infected with the highly pathogenic strain of bird flu both lived with dairy workers who had no known direct exposure to the virus, according to a CDC report. They had both consumed either raw meat or unpasteurized milk, as well.

Courtney White, vice president of veterinary medicine at the Humane Society of Huron Valley in Ann Arbor, said risk to humans and widespread exposure to community and domestic cats is considered low, but owners and caregivers at shelters should be aware of the risk factors.​..
