Highly Pathogenic Avian Influenza Detected in Ionia County Flock

April 02, 2024

As wild birds complete their spring migration, prevention is essential to keeping Michigan's animals healthy and safe

LANSING, MI - Following a report to the Michigan Department of Agriculture and Rural Development (MDARD), the Michigan State University Veterinary Diagnostic Laboratory has detected the presence of highly pathogenic avian influenza (HPAI) in a commercial poultry facility from Ionia County. Since the disease was first detected in Michigan in 2022, this is the fourth detection of HPAI in a commercial facility, and the first detection in Ionia County. As wild birds complete their spring migration, it is crucial for every producer to protect their animals from wild birds and the germs they could be carrying.

"As the weather remains cool and wild birds continue their migration, conditions are ideal for the virus to thrive and spread. While these conditions persist, the need to take preventative measures will be high," said State Veterinarian Dr. Nora Wineland, DVM, MS, DACVPM. "Keeping HPAI out of Michigan s domestic animals remains a team effort, and it must be a top priority for all."

HPAI is a highly contagious virus that can be spread in various ways from flock to flock, including by wild birds, through contact with infected poultry, by equipment, and on the clothing and shoes of caretakers. To protect other facilities in Michigan, the premises is currently under quarantine, and the birds will be depopulated to prevent disease spread. These efforts also help to ensure the safety and integrity of the commercial food supply.

"Michigan's egg farmers are among the most proactive in the country, with their diligence leading to rapid detection of HPAI in this flock," said Dr. Nancy Barr, executive director of Michigan Allied Poultry Industries. "Strict biosecurity measures are in place to protect flocks from the increased threat of HPAI."

According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with avian influenza remains low. Also, no animals or products infected with HPAI will enter the commercial food chain. As a reminder, people should properly handle and cook all food.

Whether it's a few backyard birds or a large commercial flock, following a few key steps is fundamental to protect the health and vitality of Michigan s domestic birds:
  • Prevent contact between domestic and wild birds by bringing them indoors or ensuring their outdoor area is fully enclosed.
  • Wash your hands before and after handling birds as well as when moving between different coops.
  • Disinfect boots and other gear when moving between coops.
  • Do not share equipment or other supplies between coops or other farms.
  • Clean and disinfect equipment and other supplies between If it cannot be disinfected, discard it.
  • Use well or municipal water as drinking water for birds.
  • Keep poultry feed secure to ensure there is no contact between the feed/feed ingredients and wild birds or rodents.
MDARD is continuing to work diligently with local, state, and federal partners to quickly respond to reports of HPAI to best mitigate the spread of the disease and provide outreach.

Reporting Possible Cases

For Domestic Birds

Domestic bird owners and caretakers should watch for multiple sudden deaths in the flock, a drop in egg production, a significant decrease in water consumption, diarrhea, sneezing/coughing, or an increase in sick birds. If avian influenza is suspected in domestic birds, contact MDARD immediately at 800-292-3939 (daytime) or 517-373-0440 (after- hours).

For Wild Birds

If anyone notices what appears to be unusual or unexplained deaths among wild bird populations, please report these cases to the Michigan Department of Natural Resources (DNR) by:
  • Using the DNR's Eyes in the Field app. Choose the Diseased Wildlife option among the selections for Observation Forms.
  • Calling the DNR Wildlife Disease Laboratory at 517-336-5030.

Highly Pathogenic Avian Influenza Detected in Newaygo County Flock

April 16, 2024

The risk for HPAI will remain high as wild birds continue their spring migration; keeping wild birds away is essential to protecting animal health

LANSING, MI - Following a report to the Michigan Department of Agriculture and Rural Development (MDARD), the Michigan State University Veterinary Diagnostic Laboratory has detected the presence of highly pathogenic avian influenza (HPAI) in a commercial poultry facility from Newaygo County. Since the disease was first detected in Michigan in 2022, this is the seventh detection of HPAI in a commercial facility, and the first detection in Newaygo County. As wild birds complete their spring migration, it is crucial for every producer to protect their animals from wild birds and the germs they could be carrying.

"MDARD continues to thoroughly and robustly respond to the detection of HPAI with an all-hands-on-deck approach with our federal, state, and local partners," said MDARD Director Boring. "Biosecurity remains the best tool available to combat HPAI, and we continue to encourage producers of all sizes to enhance their biosecurity measures to reduce the risk of introducing this disease to their farm. MDARD is addressing this outbreak from every angle, including working to help mitigate the economic impacts on local communities. We remain laser-focused on our mission to protect animal and public health."

"Taking preventative measures to keep wild birds away from farms is essential to combatting HPAI and limiting its impact," said State Veterinarian Dr. Nora Wineland, DVM, MS, DACVPM. "As wild birds continue to migrate and the outside temperatures remain cool and temperate, conditions are ideal for the virus to spread. This is why it is so vital for producers to assess the risks on their premises and tighten protocols. Protecting animal health is of the utmost importance."

HPAI is a highly contagious virus that can be spread in various ways including by wild birds, through contact with infected poultry, by equipment, and on the clothing and shoes of caretakers. To protect other facilities in Michigan, the premises is currently under quarantine, and the birds will be depopulated to prevent disease spread.

Avian flu infects another Michigan turkey flock
This is the first time the H5N1 virus has been confirmed in Ottawa County poultry, but it was previously reported in a dairy herd in that county.
Roy Graber
April 25, 2024​

The presence of highly pathogenic avian influenza (HPAI) has been confirmed in another commercial poultry flock in Michigan.

According to the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), the latest case involved a commercial meat turkey flock in Ottawa County. The flock included 104,000 turkeys. The case was confirmed on April 24.

This is the first instance of HPAI in Ottawa County poultry during the 2022-24 HPAI outbreak.

However, no state has been hit as hard by H5N1 HPAI in recent weeks as Michigan. In April alone, five commercial flocks have been affected, involving nearly 6.7 million birds. Two of those flocks involved turkeys, while the other three involved laying hens. All three layer flocks were in Ionia County, while the other turkey flock was in Newaygo County...

Michigan: Neighbors report smell, hazmat suits after bird flu outbreak at Michigan’s top egg producer,

Posted: May 15, 2024 / 10:51 PM EDT
Updated: May 16, 2024 / 12:03 PM EDT
by: Amber Krycka​

BOSTON TOWNSHIP, Mich. (WOOD) — About 2.6 million birds have been affected by the Highly Pathogenic Avian Influenza, or bird flu, during the latest outbreak in Michigan, according to the United States Department of Agriculture.

Last month, the virus was detected at Michigan’s top egg producer, Herbruck’s Poultry Ranch in Ionia County. Neighbors nearby say it’s been an active few weeks as state and federal regulators respond.

“It has been very smelly, lots of flies,” remarked one nearby resident who did not want to be named.

That’s how neighbors living along Grand River Avenue in Saranac describe what it’s been like over the last few weeks. ...

Pictures taken beside this neighbor’s home show workers in hazmat suits and large piles of what looks like dirt.
“They’ll take one piece of equipment, fill it up — it looks like a big pile of dirt — put it in the back of a semi, take it out to the back field,” explained the neighbor.

The poultry ranch released a statement this week:

“Herbruck’s is working closely with federal and state regulators and implementing the protocols and procedures we are required to follow as we disinfect our facilities. We are working as safely and quickly as possible to resume normal operations at our facilities,” the statement read. ...

Regulators have to dispose of birds properly, sanitize and disinfect facilities so it doesn’t spread, according to Boring (director of the Michigan Department of Agriculture and Rural Development) ...

“Composting is our preferred method of how bird disposal is conducted. It keeps the virus on site,” explained Boring. ...
