Avian Flu Regulations in Michigan: What Every Poultry Owner Must Know

Michigan has been one of the most heavily tested states in the nation when it comes to avian influenza, and the regulatory framework that governs poultry ownership here reflects that reality. Since late February 2022, Michigan has experienced die-offs in wild birds and mammals across the state due to HPAI. Whether you raise a small backyard flock or operate a large commercial turkey operation, the rules that apply to you are detailed, actively enforced, and carry real consequences for non-compliance.

Understanding the avian flu regulations in Michigan means knowing the difference between virus classifications, your registration and biosecurity obligations, how to report sick birds, and what happens if your flock is affected by an outbreak. This guide walks through each of those areas so you can protect your birds, stay compliant, and know exactly what to expect from state and federal agencies if the worst occurs.

HPAI vs. LPAI: Understanding Avian Flu Classifications in Michigan

Not all avian influenza strains are created equal. The regulatory response you face, and the severity of the disease threat to your flock, depends largely on which classification of the virus is involved. Michigan’s rules are primarily structured around two categories: highly pathogenic avian influenza (HPAI) and low pathogenicity avian influenza (LPAI).

Caused by influenza type A viruses, the disease varies in severity depending on the strain and species affected. Highly pathogenic avian influenza (HPAI) strains are deadly to domestic poultry and can wipe out entire flocks within a matter of days. Low pathogenicity avian influenza (LPAI) strains typically cause few or no signs of illness. They occur naturally in wild birds around the world. However, some LPAI strains can become highly pathogenic in poultry.

HPAI, commonly called “bird flu,” is a virus found among various species of birds. HPAI viruses can infect domestic poultry, which includes chickens, turkeys, pheasants, quail, ducks, geese, and guinea fowl. The virus also infects a wide variety of other birds, including wild migratory waterfowl. HPAI has even been detected in various species of mammals — presumably after the animals come into contact with infected wild birds.

From a regulatory standpoint, HPAI triggers the most aggressive response. In Michigan, HPAI is reportable in all species of animals. LPAI detections are also reportable and subject to regulatory oversight, but the mandatory depopulation and quarantine protocols that define Michigan’s HPAI response are specifically tied to the highly pathogenic classification.

According to the MSU Veterinary Diagnostic Lab, “The emergence and spread of avian influenza viruses, both LPAI and HPAI, is closely linked to the movement of migratory waterfowl travel along flyways.” This is why Michigan’s regulatory calendar is particularly active during spring and fall migration seasons. You can also learn more about other avian diseases that affect Michigan flocks, including avian tuberculosis and avian chlamydiosis, which carry their own reporting requirements.

Premises Registration Requirements for Poultry Owners in Michigan

One of the first steps any poultry owner in Michigan should take is registering their premises with the state. MDARD focuses on poultry health, biosecurity, disease tracking, and voluntary premises registration. While premises registration is not universally mandated at the state level for all flock sizes, it plays a critical role in how MDARD responds to disease outbreaks — and whether you are quickly notified if a detection occurs near your property.

MDARD requires no statewide permit but promotes registration and biosecurity. Many cities require local zoning or development permits; rural towns often need none for small flocks. However, voluntary registration through the USDA National Premises Identification System is strongly encouraged for all flock owners, and commercial operations are expected to be registered as a baseline for participating in state and federal disease response programs.

Registration gives MDARD the ability to contact you directly during an active outbreak, include your premises in surveillance mapping, and ensure you receive emergency alerts. To stay up-to-date with MDARD updates and alerts regarding the status of avian influenza in Michigan, poultry owners can subscribe to receive notifications from MDARD.

For commercial operations, premises registration is a prerequisite for participating in the National Poultry Improvement Plan (NPIP), which is the federal-state cooperative program that underpins biosecurity certification and interstate movement eligibility. In 2016, APHIS published an interim rule that amended indemnity regulations to require producers provide, as a condition for receiving indemnity payments, a statement that at the time of HPAI detection on their premises, they had in place and were following a poultry biosecurity plan consistent with NPIP biosecurity standards.

Biosecurity Requirements for Commercial and Backyard Flocks in Michigan

Biosecurity is the cornerstone of Michigan’s avian flu regulatory framework. Regardless of the species, biosecurity remains the best tool to combat HPAI. MDARD enforces biosecurity expectations across both commercial and backyard operations, and the standards for each are meaningfully different in scope and formality.

For commercial poultry operations, biosecurity requirements are formalized through NPIP standards and reinforced by state-level emergency orders. In 2024, Director Dr. Tim Boring signed a Determination of Extraordinary Emergency, HPAI Risk Reduction Response Order. The order requires dairy and poultry premises to implement biosecurity practices; prohibits all cattle from affected dairy herds and lactating or late pregnancy cattle from unaffected dairy herds from being exhibited until at least 60 days have passed with no new dairy detections; and prohibits all poultry from being exhibited until at least 30 days have passed with no new poultry detections.

For both commercial and backyard flock owners, MDARD recommends a consistent set of biosecurity practices. Biosecurity measures include limiting non-essential visitors to farms and washing hands before and after caring for animals. Owners are also advised not to share equipment between different farms and to clean all footwear and clothing used around sick animals with EPA-registered disinfectants. Animal owners should also secure feed to prevent contact with rodents or wild birds. MDARD suggests allowing sufficient downtime between visits to different poultry and dairy operations to prevent the virus from being carried between facilities.

• Prevent all contact between domestic birds and wild birds by housing them indoors or fully enclosing outdoor areas
• Wash hands before and after handling birds and when moving between coops
• Disinfect boots, clothing, and equipment using an EPA-registered disinfectant effective against avian influenza
• Do not share equipment, tools, or supplies between farms or coops
• Use well or municipal water as drinking water — avoid open water sources that wild birds may access
• Keep all poultry feed secured to prevent contact with wild birds or rodents
• Allow adequate downtime between visits to different poultry operations

The practice of raising chickens and turkeys indoors provides a healthy, safe, and controlled environment that minimizes the chances of spreading a variety of bird diseases including avian influenza. Poultry raised out-of-doors, often in small backyard flocks, have a much greater risk of being exposed to diseases like avian influenza which can be carried by wild birds.

Reporting Sick or Dead Birds in Michigan

Timely reporting is one of your most important legal obligations as a poultry owner in Michigan. In Michigan, HPAI is reportable in all species of animals. If avian influenza is suspected, contact MDARD immediately at 800-292-3939 (daytime) or 517-373-0440 (after-hours). These lines operate around the clock because early detection is critical to containing an outbreak before it spreads to neighboring flocks.

Knowing what signs to watch for is equally important. 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. 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 animals, by equipment, and on the clothing and shoes of caretakers.

The reporting process for domestic birds and wild birds follows separate channels in Michigan:

1. Domestic poultry and livestock: Call MDARD at 800-292-3939 (daytime) or 517-373-0440 (after-hours). MDARD will dispatch investigators and coordinate with MSU’s Veterinary Diagnostic Laboratory for testing.
2. Wild birds: If anyone notices what appears to be unusual or unexplained behaviors or deaths among wild birds and other wildlife, please report these cases to the Michigan Department of Natural Resources (DNR) through the Eyes in the Field app or by calling 517-336-5030.

MDARD cooperates with MSU’s Veterinary Diagnostic Lab (VDL) for diagnostic services. Residents who notice the death loss of three or more free-ranging birds should report it to the DNR through the Eyes in the Field app or by calling 517-336-5030.

Failing to report is not a passive risk. Federal and state indemnity programs that compensate producers for animals destroyed under official orders generally require that the producer complied with all reporting requirements. If you fail to report and the disease spreads before detection, you may be disqualified from receiving compensation for animals that are ultimately depopulated — even if those animals were on your premises through no fault of your own.

Michigan’s Current HPAI Status and Active Outbreak Zones

Michigan has been dealing with HPAI detections continuously since the current national outbreak began in early 2022. The disease has affected commercial flocks, backyard operations, dairy cattle, and wild bird populations across the state, making Michigan one of the most closely monitored states in the country for avian influenza activity.

In 2025, Michigan recorded 10 detections of HPAI in commercial poultry flocks and 12 detections in backyard flocks. Nearly all of these cases were identified during the early spring or late fall months, which coincide with wild bird migration patterns. With that latest instance of HPAI, Michigan had 10 commercial poultry flocks affected by the disease in 2025. All 10 flocks involved turkeys, and with the exception of one flock in Allegan County, all were in Ottawa County.

Ottawa County has been a persistent hotspot. Following an investigation by MDARD, the Michigan State University Veterinary Diagnostic Laboratory detected the presence of HPAI in a backyard poultry flock from Ottawa County in January 2026. This was the first detection of HPAI in a Michigan domestic flock in 2026, and the 16th case in an Ottawa County poultry flock since the virus was first detected in the state in 2022.

As of April 2026, the Michigan Allied Poultry Industry confirmed that control zones on turkey farms impacted by HPAI in the state have been lifted. However, the underlying risk has not disappeared. Monitoring of sick and dead wildlife for HPAI continues, and the disease is considered widespread and endemic across Michigan and North America.

On the dairy cattle front, Michigan made significant progress in 2025. Michigan was one of the first states to enroll in the U.S. Department of Agriculture’s National Milk Testing Strategy, requiring regular testing for HPAI in all of the state’s licensed dairy facilities. In July 2025, Michigan achieved Stage 4 / Unaffected Status, meaning the virus is no longer being detected in the state’s dairy cattle herds.

Poultry Movement and Quarantine Restrictions in Michigan

When HPAI is detected in Michigan, one of the first regulatory tools MDARD deploys is movement restriction. These restrictions are designed to prevent the virus from spreading to unaffected premises through the transport of birds, equipment, or personnel. Understanding how quarantine zones work — and what you can and cannot do within them — is essential if you operate anywhere near an active outbreak area.

Under the Animal Industry Act, MDARD has authority to quarantine your premises, restrict the movement of animals on or off your property, and require specific management or biosecurity measures while an investigation is ongoing. Quarantine orders are not punitive — they are a standard disease control tool used to prevent spread while the situation is evaluated. Cooperating fully with quarantine requirements is both a legal obligation and the most effective way to demonstrate good faith and resolve the situation as quickly as possible.

When a detection occurs, MDARD and USDA APHIS establish a structured set of geographic zones around the infected premises:

• Infected Premises (IP): The property where HPAI has been confirmed. Strict movement prohibitions apply and depopulation is initiated.
• Control Area / Quarantine Zone: A defined radius surrounding the IP, typically including a 3-kilometer infected zone and a 10-kilometer buffer zone, within which all poultry movement requires a permit.
• Surveillance Zone: A broader area beyond the control zone where enhanced monitoring and testing are conducted.

It is about a two-month process after an outbreak before producers can fill their barns again. During that window, movement of poultry into, out of, or within the control area is regulated through the Secure Poultry Supply (SPS) Plan, which provides permit pathways for non-infected operations that need to move birds while a control area is active.

Even with cold temperatures, the virus is still present in the environment and travelling through infected wild birds. MDARD continues to strongly recommend owners remain vigilant and actively protect their animals from HPAI. Movement restrictions apply to live birds, hatching eggs, and in some cases poultry products, depending on the specific emergency order in place at the time of the outbreak.

For context on how neighboring states handle similar regulatory frameworks, you can review horse boarding regulations in Wyoming and horse boarding regulations in Wisconsin, which illustrate how state-level animal regulations vary by region and species.

Flock Depopulation and Compensation Rules in Michigan

If HPAI is confirmed on your premises, depopulation will almost certainly follow. There is no treatment for HPAI. The only way to stop the disease is to depopulate all affected and exposed poultry. Understanding the depopulation process and the compensation programs available to you can make an already difficult situation more manageable.

Indemnity for depopulated poultry is authorized by APHIS as funds are available. The final determination to depopulate entire Infected Premises, or specific houses/barns on Infected Premises, or depopulate Contact Premises, is made by State or Tribal officials working in coordination with USDA APHIS. In Michigan, that means MDARD and USDA APHIS jointly direct the response.

USDA covers the cost of depopulating and disposing of HPAI-affected flocks. In most cases, USDA or its contractors carry out these activities and pay the costs directly. If you choose to manage your own depopulation activities, reimbursement is available through a formal financial plan process.

The indemnity and compensation process involves several steps:

1. Report immediately — Contact MDARD as soon as HPAI is suspected. Because you will only be indemnified for live birds and HPAI spreads quickly and can be fatal to flocks, it is critical that you report sick birds immediately and begin the indemnity process quickly if you have an infected flock.
2. Flock appraisal — A USDA case manager will be assigned to your premises. The Indemnity and Compensation Decision Determination is the first document that the producer fills out and signs for HPAI-affected birds. It captures basic information and confirms that the producer will accept fair market value for depopulated birds.
3. Depopulation and disposal — USDA or its contractors carry out depopulation. APHIS offers two methods to reimburse producers for the depopulation and/or disposal of birds affected with HPAI — the D&D Flat Rate method or the Detailed Financial Plan method.
4. Virus elimination compensation — Flat rates are paid for virus elimination activities, including barn preparation, a cleaning step, and a disinfection step. The amounts are calculated based on the area of the structures housing animals and eggs.
5. Payment — You will receive payment from USDA via direct deposit in about 2–3 weeks.

Compensation, however, is not unlimited. Producers never really made whole. They do receive indemnity for those birds, and they get support with the cleaning, disinfection, and virus removal. But they do not get any money for the loss of production. This gap in coverage is a significant financial reality for turkey and layer operations that face extended downtime following an outbreak.

Commercial poultry premises must successfully pass a biosecurity audit prior to restocking if they were previously HPAI-infected and wish to be eligible for indemnity for the restocked poultry. A biosecurity audit is also required for commercial poultry premises in the buffer zone prior to movement of poultry onto the premises, if the premises wishes to be eligible for indemnity for the poultry moved onto the premises.

Penalties for Non-Compliance in Michigan

Michigan’s animal health laws give MDARD significant authority to act against poultry owners who fail to meet their regulatory obligations. Non-compliance with avian flu regulations is not treated as a minor administrative matter — it can result in financial penalties, loss of compensation eligibility, and operational restrictions that affect your ability to keep and sell poultry.

The primary areas of non-compliance risk for poultry owners include failure to report suspected HPAI, violating quarantine or movement restrictions, and failing to meet biosecurity standards required under state or federal orders. Each carries distinct consequences.

Failure to Report

Federal and state indemnity programs that compensate producers for animals destroyed under official orders generally require that the producer complied with all reporting requirements. If you fail to report and the disease spreads before detection, you may be disqualified from receiving compensation for animals that are ultimately depopulated — even if those animals were on your premises through no fault of your own.

Violations of Quarantine and Movement Orders

Under the Animal Industry Act, MDARD has authority to quarantine your premises, restrict the movement of animals on or off your property, and require specific management or biosecurity measures while an investigation is ongoing. Violating a quarantine or movement order is a direct violation of Michigan’s Animal Industry Act and can result in civil penalties, seizure of animals, and referral for criminal prosecution in serious cases.

License and Permit Consequences

For licensed livestock dealers, transporters, and other regulated entities, a finding of non-compliance with reporting requirements can result in suspension or revocation of state-issued licenses and permits. This can effectively shut down commercial livestock operations and has long-term reputational consequences within the industry.

Biosecurity Audit Failures

If your premises previously experienced an HPAI outbreak, passing a biosecurity audit is a condition of restocking and maintaining indemnity eligibility. Because previously infected poultry premises have experienced an outbreak of HPAI and have the highest risk of reintroduction resulting from significant biosecurity lapses, APHIS must verify how well the plan is implemented and maintained on site. In order to ensure that reintroduction risks are being effectively mitigated at previously infected premises, biosecurity audits are required to be conducted in person, absent extenuating circumstances.

MDARD’s enforcement system is multilayered. MDARD enforces reporting requirements through routine inspections, laboratory notification systems, and reports from veterinarians, dealers, and other mandated reporters. Because multiple parties carry independent reporting obligations, a failure to report is often discovered through a parallel channel — a diagnostic lab result, a veterinarian’s submission, or a report from a connected farm. Assuming that non-reporting will go undetected is a significant miscalculation in Michigan’s integrated animal health surveillance system.

Staying current on Michigan’s avian flu regulations means checking MDARD’s official resources regularly, particularly during spring and fall migration seasons when outbreak risk is highest. MDARD continues to diligently work with local, state, and federal partners to quickly respond to reports of HPAI, mitigate the spread of the disease, and provide additional outreach to producers, industry, and other key stakeholders. Your compliance supports not just your own operation, but the health of Michigan’s entire poultry industry.

For related regulatory reading, Michigan poultry and livestock owners may also find value in reviewing Michigan’s reportable livestock disease rules, which cover the broader framework of disease reporting obligations that apply across species in the state.
