Avian Flu Regulations in Massachusetts Every Poultry Owner Must Know

If you keep poultry in Massachusetts — whether a backyard flock of six hens or a commercial turkey operation — avian flu regulations directly affect how you manage, move, and report on your birds. Massachusetts farmers and experts have been protecting the state’s livestock from Highly Pathogenic Avian Influenza A (HPAI) H5N1 virus since early 2022 in order to provide a safe and stable food supply for consumers. The rules governing your obligations are set by the Massachusetts Department of Agricultural Resources (MDAR), reinforced by federal USDA-APHIS standards, and carry real legal and financial consequences if ignored.

This guide walks you through every layer of avian flu regulation in Massachusetts — from understanding the difference between HPAI and LPAI, to what happens if your flock tests positive. Whether you are a first-time backyard chicken keeper or an experienced commercial producer, knowing these rules is the first step to protecting your birds, your livelihood, and your neighbors’ flocks.

HPAI vs. LPAI: Understanding Avian Flu Classifications in Massachusetts

Avian influenza A viruses are classified into two categories: low pathogenic avian influenza (LPAI) A viruses and highly pathogenic avian influenza (HPAI) A viruses. These categories refer to the molecular characteristics of the virus and the virus’s ability to cause disease and mortality in chickens in a laboratory setting — not the virus’s ability to cause disease in humans. Understanding this distinction is essential because Massachusetts law and MDAR response protocols treat the two classifications very differently.

Low Pathogenic Avian Influenza (LPAI) is a respiratory disease of poultry, turkeys, game birds, and waterfowl. Symptoms are typically mild and in many cases not present at all. The disease can manifest through depression, decreased food consumption, respiratory signs such as coughing and sneezing, and a decrease in egg production. Critically, some types of LPAI can mutate into HPAI.

HPAI is a far more serious threat. HPAI is a deadly disease for poultry that can infect all types of chickens, turkeys, and many other kinds of birds. It can strike suddenly and spread fast — infected poultry may die within hours of becoming infected. HPAI can cause a variety of clinical signs including respiratory illness, blue combs and wattles, decreased feed consumption, and decreased egg production. In some cases, sudden death has been the only sign.

When referencing an HPAI outbreak, the World Organization of Animal Health (WOAH) describes poultry flocks as “poultry” or “non-poultry.” The WOAH defines poultry as all birds reared or kept in captivity for the production of commercial animal products or for breeding for this purpose. Birds kept in a single household whose products are used exclusively within that household — and that have no direct or indirect contact with poultry or poultry facilities — are not considered poultry. Birds kept for shows, racing, exhibitions, zoological collections, and competitions, as well as pet birds, are also not considered poultry under this definition. This distinction affects which regulatory pathways apply to your specific situation.

You can learn more about related avian diseases that affect Massachusetts flocks, including avian tuberculosis and avian chlamydiosis, both of which share some reporting and biosecurity overlap with avian influenza regulations.

Premises Registration Requirements for Poultry Owners in Massachusetts

Before you can legally sell, exhibit, or move birds in Massachusetts, you must meet specific registration and licensing requirements administered by MDAR’s Division of Animal Health. These requirements apply whether you operate a commercial facility or keep a small backyard flock that you plan to show at a fair.

Diagnostic testing services for Salmonella pullorum and avian influenza in poultry are available to all residents of the Commonwealth who plan to sell, exhibit, or otherwise move birds off of their premises. This testing is not optional — it is a legal prerequisite for movement.

Pursuant to MGL Chapter 94, Section 152A, no person or business entity shall engage in the business of buying, selling, or transporting live poultry unless they have first obtained a license from the Division of Animal Health. Such a license expires on December 31 of the year in which it was issued, and there is currently no fee for this license.

All licensees must keep and maintain, for a period of one year, records of each transaction. Adult poultry entering the Commonwealth of Massachusetts must be accompanied by proof of an NPIP-approved negative test for Salmonella pullorum. Adult poultry entering Massachusetts must be accompanied by proof of an NPIP-approved negative test for Salmonella pullorum-typhoid and an NPIP/VS 9-3 form issued by the state of origin. Day-old chicks and hatching eggs must originate from flocks that are NPIP Salmonella pullorum-typhoid negative and be accompanied by an NPIP/VS 9-3 form issued by the state of origin.

Massachusetts law under MGL Chapter 129, Section 26B requires that all live poultry or hatching eggs moving within the Commonwealth originate from current certified Salmonella pullorum clean flocks. The definition of “poultry” in regard to testing requirements includes chickens, turkeys, guinea fowl, and gamebirds. All other avian species require a general health certificate for entry into the Commonwealth.

MDAR also conducts ongoing surveillance testing. MDAR continues to conduct HPAI surveillance testing for hundreds of Massachusetts flock owners that sell birds or participate in shows at agricultural fairs and other events. Registering your premises with MDAR and participating in the National Poultry Improvement Plan (NPIP) ensures you are part of this surveillance network and eligible for federal indemnity programs if an outbreak occurs on your property.

Biosecurity Requirements for Commercial and Backyard Flocks in Massachusetts

Biosecurity is the single most important tool you have for keeping avian flu out of your flock. Since wild migratory birds are natural carriers for avian influenza viruses, including HPAI, preventing wild birds from mixing with or having contact with domestic flocks is essential to disease control and prevention. MDAR has published biosecurity guidance in multiple languages to ensure all Massachusetts poultry owners can access and implement these requirements.

Domestic poultry are exposed to HPAI through contact with infected birds, their droppings, or feathers. Pastures, yards, ponds, and equipment can easily become contaminated with HPAI virus. Flock owners and visitors may accidentally expose their flocks to HPAI through contaminated shoes, clothing, or equipment.

MDAR and state health officials have outlined the following core biosecurity practices that all poultry owners — commercial and backyard alike — are expected to follow:

• Separate domestic birds from wild birds: Poultry owners should practice strong biosecurity measures to keep birds away from wild birds, particularly wild waterfowl, feathers, and droppings. Owners with water bodies on their property should take steps to mitigate wild waterfowl from frequenting those areas. Eliminating standing water and preventing domestic birds from having access to ponds, streams, and wetland areas that attract wild waterfowl is critical.
• Quarantine new arrivals: New birds should be completely isolated for at least one month prior to being added to a domestic flock.
• Isolate returning birds: Birds returning home from fairs or shows should also be isolated from the home flock as if they were new arrivals.
• Limit access: Limit the number of people that have access to your flock. Do not share equipment with other bird owners without thoroughly cleaning and disinfecting between locations.
• Avoid unnecessary movement: Avoid unnecessary movement of poultry between locations and be aware of the potential to carry HPAI-contaminated materials onto properties where domestic birds are kept.

APHIS has established requirements for certain poultry premises to complete a biosecurity audit as a condition for receiving indemnity payments for poultry depopulated because of an HPAI outbreak. This means that if you have not documented and implemented a biosecurity plan before an outbreak occurs, you may forfeit your eligibility for financial compensation — making proactive biosecurity planning both a regulatory and financial necessity.

Reporting Sick or Dead Birds in Massachusetts

Timely reporting is one of your most important legal obligations as a poultry owner in Massachusetts. Timely reporting of sick and dying birds is a critical factor to prevent the virus from spreading to other poultry flocks. Delays in reporting not only risk spreading disease to neighboring farms but can also disqualify you from receiving compensation for depopulated birds.

Massachusetts uses a two-track reporting system depending on whether the birds are domestic or wild:

The public should report observations to MassWildlife of sick or deceased birds if five or more birds are found at a single location. For domestic birds, the public should report sick or dead poultry or other domestic birds by calling MDAR’s Division of Animal Health at (617) 626-1795 or through mass.gov/reportpoultry.

You should not wait for multiple birds to die before making a call. Reimbursement does not apply to birds that die of the disease, so it is essential that flock owners notify the Department immediately upon signs of trouble. The moment you observe symptoms consistent with HPAI — such as sudden death, respiratory distress, blue discoloration of the comb or wattles, or a sharp drop in egg production — contact MDAR without delay.

For public health concerns related to potential human exposure, people with questions about the public health impact of HPAI can visit DPH’s Avian Influenza webpage or call the Division of Epidemiology, available 24/7, at 617-983-6800. If you had direct exposure to sick or dead birds without wearing personal protective equipment, contact that number promptly.

Massachusetts’s Current HPAI Status and Active Outbreak Zones

Massachusetts has experienced recurring HPAI detections since the current national outbreak began. Massachusetts has faced recurring outbreaks of Highly Pathogenic Avian Influenza virus since 2022. Understanding the current status of the virus in the state helps you assess your flock’s risk level and whether enhanced precautions are warranted in your area.

As of January 2026, the Massachusetts Department of Agricultural Resources and its partner agencies depopulated and disposed of one non-commercial, backyard flock (WOAH non-poultry) in Dukes County due to Highly Pathogenic Avian Influenza. Birds on the affected premises exhibited clinical signs consistent with HPAI and tested positive for the disease. A previous detection was confirmed in Barnstable County, where MDAR and its partner agencies depopulated and disposed of a non-commercial, mixed-species backyard flock. Birds on the affected premises exhibited clinical signs consistent with HPAI and tested positive for the disease.

There was also a reported case of HPAI in a domestic flock in Plymouth County in January 2025. As of that time, there had never been a reported positive case of bird flu in a commercial poultry operation in Massachusetts.

The wild bird population continues to be the primary driver of risk. HPAI has been detected across Massachusetts and is the suspected cause of mass mortality events for wild birds in numerous municipalities. Avian influenza is considered to be widespread in waterfowl and other birds in Massachusetts. The HPAI virus is continuing to circulate in the wild bird population, particularly in wild waterfowl.

On the dairy side, Massachusetts has been proactive. MDAR, along with the Massachusetts Department of Public Health, completed H5N1 avian flu testing of all 95 licensed dairy farms in the state, with no positive samples found. MDAR stated it is the only state in the nation to test all dairy herds and find no evidence of H5N1 infection. Bulk milk tank testing in Massachusetts continues and to date has shown no evidence of infection in Massachusetts dairy cattle herds.

For the most current outbreak zone information, check the MDAR Avian Influenza page and the USDA APHIS HPAI detection page, both of which are updated as new cases are confirmed.

Poultry Movement and Quarantine Restrictions in Massachusetts

When HPAI is detected in Massachusetts, MDAR and USDA-APHIS establish geographic control zones that impose strict restrictions on the movement of poultry, eggs, equipment, and people. Understanding how these zones work — and what they mean for your operation — is critical to staying in compliance during an active outbreak.

The federal response framework establishes two primary zones around an infected premises:

1. Infected Zone (Infected Premises): The property where HPAI has been confirmed. All birds on the premises are subject to immediate depopulation. No poultry, eggs, manure, or flock-related equipment may leave without authorization from state and federal officials.
2. Control Area: A defined perimeter surrounding the infected premises, typically encompassing a larger radius. The current regulations do not provide a sufficient incentive for producers in control areas or buffer zones to maintain biosecurity throughout an outbreak — which is precisely why APHIS has strengthened requirements for biosecurity compliance audits as a condition of receiving indemnity within these zones.

Poultry owners should avoid unnecessary movement of poultry between locations and be aware of the potential to carry HPAI-contaminated materials onto properties where domestic birds are kept. During an active outbreak in your county or a neighboring county, this guidance effectively becomes a mandatory precaution backed by quarantine authority.

For birds entering Massachusetts from other states, adult poultry entering the Commonwealth must be accompanied by proof of an NPIP-approved negative test for Salmonella pullorum-typhoid and an NPIP/VS 9-3 form issued by the state of origin. Day-old chicks and hatching eggs must originate from flocks that are NPIP Salmonella pullorum-typhoid negative and be accompanied by an NPIP/VS 9-3 form issued by the state of origin.

Birds used for restocking after depopulation must be from flocks tested for HPAI and/or from an NPIP commercial flock. If birds used for restocking are being sourced from a premises located in an active Control Area, then testing and permitting requirements must be met before movement. State or federal animal health officials may require producers to test birds used for restocking from premises located outside an active Control Area as well.

You can also review how neighboring states handle animal movement regulations — for example, horse boarding regulations in Wyoming and horse boarding regulations in Wisconsin illustrate how states vary in their approach to livestock movement and premises registration requirements.

Flock Depopulation and Compensation Rules in Massachusetts

If HPAI is confirmed on your premises, depopulation is not optional. Once a flock is tested and confirmed as infected with HPAI, any remaining birds will need to be humanely euthanized to control the spread of the disease. This process is carried out under the joint authority of MDAR and USDA-APHIS, and it follows a structured protocol designed to eliminate the virus as quickly as possible while protecting the financial interests of affected producers.

The U.S. government’s primary control strategy is the “stamping-out policy.” This strategy is defined by international standards and WOAH as the killing of animals that are affected and those suspected of being affected in the herd or flock, and where appropriate, those in other herds or flocks that have been exposed to infection. Depopulation of the flock is followed by disposal of carcasses and decontamination of the areas that sick animals had come in contact with via thorough cleaning and disinfection.

In almost all cases, water-based foam, carbon dioxide, or alternative methods will be the depopulation methods available to rapidly stamp out the HPAI virus in poultry. The specific method used on your premises will depend on flock size, housing type, and available resources.

Compensation and Indemnity

A program has been established by the USDA to compensate flock owners for any animals depopulated as part of the control efforts. The reimbursement does not apply to birds that die of the disease, so it is essential that flock owners notify the Department immediately upon signs of trouble.

APHIS offers two methods to reimburse producers for the depopulation and disposal of birds affected with HPAI: the D&D Flat Rate method or the Detailed Financial Plan method. The process for receiving payment works as follows:

1. Work with your case manager or Field Reimbursement Specialist to fill out and sign an indemnity request form. USDA will begin depopulation work and prepare the initial indemnity value. You will receive paperwork indicating the indemnity amount.
2. Register your business with the U.S. Government System for Award Management (SAM). Complete and sign the paperwork, including your bank information and SAM registration information, and return it to your case manager or Field Reimbursement Specialist.
3. You will receive payment from USDA via direct deposit in about two to three weeks. If you appeal the initial indemnity value and your appeal is successful, additional funds would be deposited at a later time.

USDA will also compensate you for materials, such as contaminated feed or egg packaging, that must be destroyed because they cannot be safely or adequately cleaned. To receive compensation for these items, your Field Reimbursement Specialist must review and approve the items in writing before you remove or disassemble them.

Owners of fancy or exotic birds should keep receipts and sales records that will help establish the value of your flock before any outbreak occurs. Having documentation of purchase prices, breeding records, and show certifications will support a stronger indemnity claim.

After depopulation, restocking is subject to a mandatory waiting period. A premises may only seek approval to restock after completing a 14- or 28-day fallow period after final virus elimination, after environmental sampling is complete and shows no evidence of HPAI, and after the premises meets requirements of the State Quarantine Notice/Hold Order and the USDA Flock Plan.

Penalties for Non-Compliance in Massachusetts

Failing to comply with Massachusetts avian flu regulations carries consequences that range from loss of financial compensation to criminal liability under state law. MDAR has the authority to enforce the Commonwealth’s animal health statutes, and USDA-APHIS can enforce federal requirements independently. Non-compliant poultry owners face exposure on both fronts.

Loss of Indemnity Eligibility

The most immediate financial penalty for non-compliance is the loss of federal indemnity payments. As a condition for receiving indemnity payments, producers must provide 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. If you cannot demonstrate that a biosecurity plan was in place and actively followed at the time of detection, APHIS can deny or reduce your indemnity claim — meaning you absorb the full financial loss of a depopulated flock.

Experience with the 2022–2024 HPAI outbreak indicated that previous indemnity rules were insufficient to address initial introduction of HPAI into flocks on premises in proximity to infected sites. As a result, APHIS strengthened its requirements, and biosecurity non-compliance is now a formal disqualifying factor for compensation.

State Law Violations

Massachusetts General Laws governing animal health — including MGL Chapter 129 and MGL Chapter 94, Section 152A — establish criminal and civil penalties for violations related to unlicensed poultry trading, failure to comply with quarantine orders, and obstruction of disease control efforts. Violations of the licensing requirement under MGL Chapter 94, Section 152A can result in fines and loss of operating authority. Failure to comply with a MDAR quarantine or hold order is a violation of MGL Chapter 129, which governs animal disease control and grants MDAR broad enforcement authority, including the power to seize animals and seek injunctive relief.

Federal Penalties

At the federal level, violations of USDA-APHIS movement orders and quarantine restrictions can result in civil penalties under the Animal Health Protection Act (7 U.S.C. § 8313), which provides for fines of up to $50,000 per violation for individuals and up to $250,000 per violation for businesses. Knowingly moving birds in violation of a federal quarantine order — or concealing a suspected HPAI infection — can escalate to criminal charges.

Compliance Audit Requirements

As part of the biosecurity audit required for indemnity eligibility, the Official State Agency will evaluate the poultry biosecurity plan itself against 14 biosecurity principles articulated in the NPIP Program Standards policy document, and review documentation showing that the poultry biosecurity plan is being implemented. Keeping written records of your biosecurity practices — cleaning logs, visitor logs, quarantine records for new birds — is the most effective way to demonstrate compliance and protect your indemnity eligibility.

Staying informed through official MDAR channels is your best defense against inadvertent non-compliance. Bookmark the MDAR Avian Influenza page, register your premises with the Division of Animal Health, and contact MDAR at 617-626-1795 any time you have questions about your specific obligations. You may also find it useful to review how other states structure their animal health and outdoor activity regulations — resources such as bass fishing regulations in Ohio and fly fishing regulations in Vermont illustrate how state agencies publish and update compliance requirements across different sectors.

Avian flu regulations in Massachusetts are designed not to burden poultry owners, but to protect them — and the broader agricultural community — from a disease that can devastate a flock overnight. By registering your premises, implementing a documented biosecurity plan, reporting sick birds immediately, and staying current on MDAR guidance, you put yourself in the strongest possible position: legally protected, financially eligible for compensation, and prepared to respond effectively if HPAI arrives at your door.
