Avian Flu Regulations in Vermont: What Every Poultry Owner Needs to Know

Vermont poultry owners — whether you manage a 10-bird backyard flock or a large commercial operation — are operating in an environment where avian flu remains an active and ongoing threat. Since spring 2022, the state has recorded multiple confirmed HPAI detections in domestic flocks, and wild birds carrying the virus have been found in every region of the state.

Understanding Vermont’s avian flu regulations is not just a matter of legal compliance; it is one of the most effective tools you have for protecting your birds, your livelihood, and your neighbors’ flocks. This guide walks you through every major regulatory area — from disease classifications and premises registration to quarantine zones, depopulation procedures, and the consequences of non-compliance.

HPAI vs. LPAI: Understanding Avian Flu Classifications in Vermont

Avian influenza is not a single uniform disease. It is classified by pathogenicity — that is, how severely it affects domestic poultry — and the classification determines everything from how officials respond to what your legal obligations are.

Highly Pathogenic Avian Influenza (HPAI) is the more dangerous of the two classifications. HPAI strains are deadly to domestic poultry and can wipe out entire flocks within a matter of days. While waterfowl can carry the disease without becoming sick, the HPAI H5 virus is generally fatal for domestic poultry. The strain currently circulating in Vermont and across the United States is H5N1.

Low Pathogenicity Avian Influenza (LPAI) presents very differently. LPAI strains typically cause few or no signs of illness and occur naturally in wild birds around the world. However, some LPAI strains can become highly pathogenic in poultry. APHIS has established specific guidance procedures for indemnity and compensation claims in cases of H5/H7 LPAI in poultry, which are handled separately from HPAI response protocols.

The regulatory response differs significantly between the two. Because LPAI does not typically kill poultry the way HPAI does, there may be control options beyond depopulation. For example, quarantine or controlled marketing may also be appropriate. If your farm is ever affected by LPAI, federal and state officials will work with you to determine what options are available.

Signs of HPAI in domestic poultry include sudden death without prior symptoms, severe respiratory distress, dramatic drops in egg production, swelling of the head and wattles, and neurological signs such as loss of coordination. LPAI-infected poultry usually don’t show any signs of illness, but if they do, you may see mild to severe respiratory distress, lack of energy and appetite, decreased egg production, and diarrhea. You can also read about related avian diseases such as avian tuberculosis and avian chlamydiosis to better understand the full spectrum of respiratory and systemic illnesses that can affect your flock.

Premises Registration Requirements for Poultry Owners in Vermont

One of the most important — and most overlooked — regulatory steps for Vermont poultry owners is premises registration. All poultry owners, regardless of size and business structure, should obtain a federal premises identification number by calling the State Veterinarian’s Office at (802) 828-2421.

This step matters more than many owners realize. A unique farm identifier will aid regulatory officials in providing information to owners pre-outbreak and assisting owners with disease control and business continuity during a disease response. In plain terms, if an outbreak occurs in your area, registered premises are the first to receive notification, guidance, and support.

• Registration applies to all poultry operations — backyard coops, hobbyist flocks, and commercial producers alike
• Contact the State Veterinarian’s Office at (802) 828-2421 to register and receive your premises ID
• Registration is free and is separate from any licensing or commercial permit requirements
• Your premises ID is used in all official disease response communications and movement permitting

Vermont also participates in the National Poultry Improvement Plan (NPIP). The NPIP was started in the early 1930s to coordinate state programs aimed at the elimination of pullorum disease from commercial poultry. Today it serves a broader biosecurity and disease management role, and NPIP certification is often required for interstate movement of poultry and hatching eggs. Commercial producers should confirm their NPIP status with VAAFM.

Biosecurity Requirements for Commercial and Backyard Flocks in Vermont

Biosecurity is the foundation of Vermont’s avian flu prevention strategy. Biosecurity refers to procedures used to prevent the introduction and spread of disease-causing organisms in poultry flocks. Initiating and maintaining a biosecurity program is an important aspect of a poultry health maintenance program.

The primary method of spreading disease-causing microorganisms between poultry flocks is the use of contaminated equipment or exposure to contaminated clothing and footwear of humans. Infected animals, such as wild birds and rodents, can also be a source of disease for poultry flocks. Disease-causing viruses and bacteria can be transported from one flock to another on bird-transporting equipment, trucks, tractors, and other farm equipment, as well as egg flats and cases.

VAAFM expects all poultry owners to follow a baseline set of biosecurity practices. The core requirements and recommendations include:

• Keep poultry away from wild birds, particularly waterfowl and shorebirds, and remove wild bird attractants from poultry housing areas.
• If poultry are housed indoors, don’t let wild birds or their fecal material into barns. Clean and disinfect all equipment prior to entry into a barn or poultry housing area.
• Do not introduce poultry from other farms without a quarantine period. Use personal protective equipment such as dedicated coveralls and boots.
• Restrict unrestricted human movement and interaction with poultry and backyard birds.
• If you exhibit your poultry at fairs or swaps, do not share cages or equipment with other poultry owners.

Commercial poultry producers face additional requirements. Commercial poultry producers — including egg producers and meat bird producers — should take additional proactive steps, such as evaluating carcass disposal options and ensuring easy access to complete farm records that include live poultry and poultry product movement on and off the property, as well as other non-poultry related routine farm traffic. They should also implement and consistently utilize a visitor’s log.

Regarding exhibitions and fairs: given the continued high risk of HPAI to poultry and livestock, no waterfowl such as ducks, geese, or swans may be shown or exhibited during Vermont fair seasons, regardless of origin. Vermont Animal Health Officials recommend against competitions, exhibitions, shows, swaps, or other in-person gatherings or commingling events of domestic fowl or poultry.

You can request a free biosecurity kit from the Animal Health Section by calling (802) 828-2421. The USDA’s Defend the Flock program also offers videos, checklists, and a full biosecurity toolkit that applies to both backyard and commercial operations.

Reporting Sick or Dead Birds in Vermont

Prompt reporting is both a regulatory obligation and a critical line of defense against wider spread. All bird owners, whether commercial producers or backyard enthusiasts, are encouraged to practice good biosecurity, prevent contact between their birds and wild birds, and report sick birds or unusual bird deaths to state and federal officials as soon as possible.

The Orleans County detection in December 2025 illustrates exactly how the reporting process should work. The flock of about 300 birds suffered its first mortality on Saturday, November 29th and then experienced ongoing losses. The owner contacted VAAFM to report the situation Saturday morning. That prompt call triggered an immediate response from both VAAFM and USDA APHIS.

Here is how to report in Vermont:

1. Contact VAAFM directly at (802) 828-2421 — this is the State Veterinarian’s Office line
2. Use the USDA toll-free number at 1-866-536-7593, available 24 hours a day
3. Contact your private veterinarian first if you want a professional assessment before calling officials — vets are required to report suspected HPAI to authorities

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. Delays in reporting not only risk wider spread but can also jeopardize your eligibility for compensation.

Animal health professionals — including veterinarians, diagnostic laboratories, and public health, zoo, or wildlife personnel — report diagnosed or suspected cases of nationally listed reportable animal diseases to APHIS Area Veterinarians in Charge and to the state animal health official as applicable under state reporting regulations.

Vermont’s Current HPAI Status and Active Outbreak Zones

Vermont has experienced multiple confirmed HPAI detections in domestic flocks since the current outbreak cycle began. Between the spring of 2022 and December of 2025, HPAI was detected in six Vermont flocks, including one in Windsor County in January of 2025, according to Agency of Agriculture news releases.

The most recent confirmed cases prior to this publication include:

• In December 2025, VAAFM and USDA APHIS detected the presence of HPAI in a backyard poultry flock in Orleans County.
• In January 2025, VAAFM and USDA APHIS confirmed HPAI in a non-commercial backyard flock in Windsor County.
• In December 2024, VAAFM and USDA APHIS confirmed HPAI in a non-commercial backyard flock in Franklin County.

Wild bird detections are also widespread throughout the state. HPAI has been detected in a variety of wild birds in Vermont, including bald eagles, red-tailed hawks, Canada geese, wood ducks, mallards, black ducks, and turkey vultures. Infected birds have been found in all regions of Vermont.

At the national level, A(H5) bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and U.S. dairy cows with sporadic human cases in U.S. dairy and poultry workers. While the current public health risk is low, CDC is watching the situation carefully and working with states to monitor people with animal exposures.

Vermont also participates in ongoing milk surveillance as part of the broader HPAI monitoring effort. On a bi-monthly basis, the Vermont Agency of Agriculture, Food and Markets samples and tests milk from each of the 450 dairy farms in Vermont in an effort to prevent the spread of HPAI. This surveillance helps provide an early warning signal for virus presence in agricultural settings across the state.

Poultry Movement and Quarantine Restrictions in Vermont

When an HPAI detection is confirmed, Vermont and USDA officials immediately establish geographic control zones that impose strict movement restrictions. The Orleans County response in December 2025 provides a clear example of how this works in practice.

As part of the response, VAAFM established a 10-kilometer control zone around the flock location. Movement of poultry and poultry products in this area was restricted — in and out — and could only occur with permitting. Additionally, VAAFM established a 20-kilometer surveillance zone around the affected premises.

The standard APHIS control area structure works as follows:

Vermont’s Secure Egg Supply (SES) Plan promotes food security and animal health through continuity of market planning for an HPAI outbreak. This plan makes specific science- and risk-based recommendations that state officials and emergency planners can use to rapidly decide whether to issue or deny permits for the movement of egg industry products during an HPAI outbreak.

Outside of active control zones, general movement best practices still apply. It is recommended that new poultry being brought to farms be quarantined before being introduced to an existing flock. This applies during both outbreak and non-outbreak periods. You should also maintain records of all poultry movements on and off your property, as these will be required if your premises falls within a control zone.

Flock Depopulation and Compensation Rules in Vermont

If HPAI is confirmed on your premises, depopulation — the humane destruction of the entire affected flock — is the required response. There is no treatment for HPAI. The only way to stop the disease is to depopulate all affected and exposed poultry.

The Windsor County case in January 2025 and the Orleans County case in December 2025 both followed this protocol. In the Orleans County case, the remaining flock was quarantined to prevent the spread of disease and was depopulated by officials from VAAFM and USDA, with the agreement and understanding of the flock’s owners.

Federal compensation is available to offset your losses. APHIS provides indemnity and compensation to producers to remove animals classified as affected, suspect, or exposed to diseases of concern, including HPAI. Here is how the process works:

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 2–3 weeks. If you appeal the initial indemnity value and your appeal is successful, additional funds would be deposited at a later time.

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. 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.

Regarding indemnity table values: the 2026 USDA Indemnity Table posted April 30, 2026 was published in error. The document is under review, and USDA anticipates it will be available by the end of June 2026. The 2025 Indemnity Table values remain in effect until further notice.

There is an important condition on compensation eligibility. A December 2024 federal interim rule — effective December 31, 2024 — 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. 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.

For smaller backyard flocks, a simplified process applies. If the flock has more than 500 birds or a total indemnity and compensation cost of more than $10,000, use the 1H – Indemnity and Compensation Request form. If the flock has 500 birds or less or a total indemnity and compensation cost equal to or less than $10,000, use the 2H – HPAI-Affected Backyard Flock Management Agreement.

A proposed federal bill — the Healthy Poultry Assistance and Indemnification Act (HPAI Act), introduced in 2025, proposes financial compensation for producers who suffer losses due to depopulation orders. As of April 2025, the Act had been introduced but not yet enacted. Monitor updates through the USDA APHIS indemnity page for any changes to compensation programs.

Penalties for Non-Compliance in Vermont

Vermont’s avian flu regulatory framework is backed by both state and federal enforcement authority. Failure to comply with reporting requirements, movement restrictions, or biosecurity orders can result in serious consequences — including loss of compensation eligibility, civil penalties, and criminal liability in the most severe cases.

Key areas where non-compliance carries direct consequences include:

The December 2024 interim rule was specifically designed to reduce the risk that a producer becomes inclined to disregard biosecurity because they believe that APHIS will continue to cover the costs associated with HPAI damages through indemnity payments regardless of their biosecurity status. The prior regulations did not provide a sufficient incentive for producers in control areas or buffer zones to maintain biosecurity throughout an outbreak.

Under the federal Animal Health Protection Act, willful violations related to interstate movement of diseased animals can result in civil penalties of up to $50,000 per violation for individuals and up to $250,000 per violation for organizations. Criminal violations can carry fines and imprisonment. Vermont state law also grants VAAFM authority to issue stop-movement orders, quarantine premises, and pursue enforcement through the Vermont Agency of Agriculture’s administrative process.

The most effective way to stay compliant — and to protect your birds — is to stay informed, register your premises, maintain strong biosecurity, and report any signs of illness immediately. Bookmark the Vermont Agency of Agriculture’s avian influenza preparedness page and check it regularly, especially during spring and fall wild bird migration seasons when HPAI risk is highest.
