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

Washington State has faced avian influenza pressure longer than most poultry owners would like. The first outbreak of high-pathogenic avian influenza occurred in Washington in 2014, and the disease has never fully left. Whether you raise a backyard flock of six hens or manage a large commercial operation, the rules governing how you register, protect, report, and respond to bird flu carry real legal weight.

This guide walks you through every layer of avian flu regulation in Washington — from understanding the two classifications of the virus to what happens if your flock tests positive. Knowing these rules before an outbreak reaches your county is the only way to stay ahead of it.

HPAI vs. LPAI: Understanding Avian Flu Classifications in Washington

Avian influenza is described as low-pathogenic avian influenza, or LPAI, and high-pathogenic avian influenza, or HPAI. The distinction between these two classifications drives nearly every regulatory decision you will encounter as a flock owner in Washington.

The low-pathogenic strain occurs naturally in wild birds and can spread to domestic birds. In this form, the disease is typically not fatal, however it can cause respiratory problems in some birds. Low-pathogenic avian influenza has been found in wild birds in Washington for many years.

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.

Avian influenza viruses are highly contagious among birds through saliva, nasal secretions, feces, and contaminated surfaces. Symptoms in birds may include eye swelling, respiratory illness, gastrointestinal problems, neurological signs such as tremors and seizures, and sudden death.

The regulatory response also differs by classification. 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. With HPAI, no such flexibility exists — depopulation is mandatory. You can also read about related poultry diseases such as avian tuberculosis and avian chlamydiosis to understand the broader spectrum of threats your flock may face.

Premises Registration Requirements for Poultry Owners in Washington

Registering your premises is one of the most important steps you can take as a poultry owner in Washington. The Washington State Department of Agriculture (WSDA) allows flock owners to register for a federal Premises Identification Number (PIN), which ties your property to the state and federal animal health tracking system. This registration is what allows WSDA to contact you quickly during an outbreak and is foundational to any compensation claim if your flock is ever depopulated.

For producers who want to sell or ship birds across state lines, the National Poultry Improvement Plan (NPIP) provides a higher tier of certification. The objective of the NPIP is to provide a cooperative Industry, State, and Federal program through which new diagnostic technology can be effectively applied to the improvement of poultry and poultry products throughout the country. The provisions of the NPIP, both technical and management, have been developed jointly by industry members and State and Federal officials. These provisions establish standards for the evaluation of poultry breeding stock and hatchery products with respect to freedom from egg-transmitted and hatchery-disseminated diseases. Through this work, the NPIP provides certification that poultry and poultry products destined for interstate and international shipment are free of all such diseases.

To become NPIP certified, and to remain certified, you must have a minimum of 30 birds, over the age of 16 weeks, tested for Pullorum Typhoid (PT) and Avian Influenza (AI) on an annual basis. NPIP also requires flock owners to annually report accurate flock numbers and stock codes for all birds on the premise at the time of reporting.

The Washington State Veterinarian’s office requires permits and Certificates of Veterinary Inspection for all animals moved into the state. If you are importing birds from out of state, this requirement applies to you regardless of flock size.

Biosecurity Requirements for Commercial and Backyard Flocks in Washington

Biosecurity is Washington’s primary regulatory tool against avian flu spread. Practicing good biosecurity is the way to protect your flock. That means taking steps to prevent your flock from coming in contact with wild birds — especially waterfowl — and their droppings. How you accomplish this depends on the setup of your farm. Some basic tips include keeping your birds confined in an area with a roof that does not allow water through (netting does not work.)

The WSDA recommends different levels of biosecurity depending on whether you operate a commercial or backyard flock, but the core principles are consistent across both.

Core Biosecurity Practices for All Flock Owners

• Limit and record your movements and the movement of vehicles onto farms.
• Wash and disinfect items going on and off farms, such as footwear, vehicles, and equipment.
• Feed and water should be kept indoors or under cover to prevent contamination.
• Flock additions or returning birds (e.g., from fairs or shows) should be quarantined for at least 30 days before mixing with existing birds.
• Use separate equipment for healthy and sick animals. Prevent contact between healthy animals and those suffering from illness.
• Clean and disinfect animal handling facilities and equipment.
• Do not allow poultry, waterfowl, and wildlife to share water sources and feeders.

Disinfection Standards

Don’t forget that in order to disinfect, you must first clean the surface — removing any debris. Once the surface is cleaned, you can apply the disinfectant to sanitize the surface. WSDA references the Center for Food Security and Public Health disinfectant list as a guide for choosing products with the right active ingredients.

Personal Protective Equipment (PPE)

PPE requirements are especially important during periods of elevated HPAI risk. In general, wearing coveralls, boots that can be disinfected, gloves, and eye protection can help protect workers from splashes and sprays on a farm. Use more than your usual PPE if there are cows, birds, or other animals sick with signs of H5N1 or if H5N1 has been confirmed.

Washington state has PPE in stock and can make it available to commercial facilities upon request. Available PPE includes disposable gloves, N95 masks, and eye protection including safety goggles and face shields.

Reporting Sick or Dead Birds in Washington

Timely reporting is one of Washington’s most critical regulatory requirements. By state law, certain animal diseases must be reported to the State Veterinarian’s Office. The full list is identified in WAC 16-70-020 of the state’s Administrative Code. Both HPAI and LPAI are on that list.

The reporting pathway depends on whether you are dealing with domestic or wild birds:

Please report sick or dead birds to the appropriate agency. Wild birds should not be touched or moved; they should be reported using the Washington Department of Fish and Wildlife’s online reporting tool. Domestic birds experiencing illness or death should be reported to the Washington State Department of Agriculture’s Avian Health Program at 1-800-606-3056 or using their online reporting tool.

Once you submit a report, the process moves quickly. Once WSDA receives your report, one of their veterinarians will review it and contact you to learn more about your specific situation and to evaluate how likely it is that you may have signs of HPAI in your flock. If there are enough signs that your flock seems high risk for having HPAI, a veterinarian will visit your flock to test it for HPAI. If it seems less likely that your flock has HPAI, the veterinarian will provide tips for continuing to monitor your flock and how to enhance biosecurity.

If you submit a bird flu report and WSDA veterinarians believe you may have HPAI, they will test your flock at no charge to you. Testing will usually happen within 24 hours of when a WSDA veterinarian reviews your report if they believe you may have HPAI.

Washington’s Current HPAI Status and Active Outbreak Zones

Washington has experienced ongoing HPAI pressure since the national outbreak began. Since the beginning of the outbreak period in 2022, 4.1 million domestic birds have been euthanized across 24 counties in Washington state.

WSDA has confirmed cases of HPAI in domestic flocks in Jefferson, San Juan, and Clark counties (as of December 2025), bringing that year’s total number of affected counties to 10. Over that same period, WSDA also recorded first-time detections in Clark, Grant, Island, and Grays Harbor counties, underscoring how widely the virus is circulating.

WSDA maintains a 2026 table of highly pathogenic avian influenza cases in Washington domestic birds, last updated March 30, 2026. You should check that table regularly if you are in a county with recent detections, as outbreak zones and quarantine boundaries can shift with each new confirmation.

The Washington State Department of Fish and Wildlife (WDFW) has reported detections in wild birds, and WSDA has confirmed cases in domestic poultry within Washington. Wild waterfowl migrating through the state are the primary vector driving new introductions each season. The WDFW bird flu page tracks wild bird detections and is updated regularly.

For the most current national picture, 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. The CDC’s current situation page and the USDA APHIS avian influenza page provide federal-level tracking.

Poultry Movement and Quarantine Restrictions in Washington

When HPAI is confirmed in Washington, movement restrictions activate quickly and apply to a defined geographic area around the affected premises. Understanding how these zones work before an outbreak reaches your area will help you avoid unintentional violations.

In the event that a control zone is established in the area of a commercial farm, specific permit forms can be used to request authorization to move animals or products, including slaughter movement permits. Completed permits can be emailed to WSDA’s Animal Health program.

Movement restrictions in Washington generally follow the federal HPAI response framework, which establishes:

• Infected Zone: The premises where HPAI has been confirmed. No movement of live birds, eggs, or poultry products is permitted without an approved permit.
• Control Area: A buffer zone surrounding the infected premises, typically extending several miles. Poultry movement within or out of this zone requires permits and may require negative testing.
• Surveillance Zone: A broader monitoring area where heightened biosecurity and reporting requirements apply.

With HPAI detections, APHIS coordinates the emergency response, working closely with Federal, State, Tribal, and industry partners. WSDA operates within this federal framework, meaning Washington’s movement restrictions align with national HPAI response protocols.

The Washington State Veterinarian’s office requires permits and Certificates of Veterinary Inspection for all animals moved into the state. Veterinarians are tracking all animals imported from affected states. If you are purchasing birds from another state during an active outbreak period, this requirement is non-negotiable.

Flock Depopulation and Compensation Rules in Washington

If your flock tests positive for HPAI, depopulation is mandatory. There are no treatment options and no exceptions. There is no treatment for HPAI. The only way to stop the disease is to depopulate all affected and exposed poultry.

If your flock tests positive for bird flu, the entire flock will need to be euthanized — both to prevent the spread of the disease and because it is humane; dying of bird flu is a slow and painful death for the bird. WSDA staff will euthanize the birds and will also usually dispose of the birds depending on your situation. Only birds on your property will be euthanized; neighboring flocks will not be euthanized unless they also test positive.

Compensation Through USDA

For flock owners who have invested in their birds or earn income from them, in some cases the USDA will provide compensation for the loss of birds euthanized to contain an outbreak of avian influenza. This compensation program is administered at the federal level through USDA APHIS.

To help producers enhance their biosecurity practices, USDA is offering additional support for producers who have HPAI confirmed positive herds so they have tools to eliminate the virus and can protect their animals, themselves, their families, and their employees. Producers with premises that have been confirmed positive for HPAI are eligible for USDA support to conduct activities that best fit their operations.

Support for these interventions is available for a period of up to 120 days from the date of confirmation of HPAI on the affected premises.

What Compensation Typically Covers

Penalties for Non-Compliance in Washington

Washington takes animal health law violations seriously, and the penalty framework reflects that. The Animal Services Division Compliance Program provides law enforcement in support of the Animal Health, Avian Health, Animal Disease Traceability, and Livestock Identification programs. Designated by statute as Agriculture Officers, they are State of Washington Limited Authority Law Enforcement Officers and conduct investigations and enforcement to detect and apprehend violators of the laws relating to any division under the supervision of the Director of Agriculture.

The following RCW Chapters are commonly investigated by the Compliance Program, both containing civil and criminal violations, with penalties ranging from civil fines up to criminal prosecution: RCW 16.36 (Animal Health) and RCW 16.57 (Identification of Livestock). RCW 16.36 is the primary statute governing avian disease reporting and control obligations.

Key Violations and Their Consequences

• Failure to report suspected HPAI: Reporting is required by state law under WAC 16-70-020. Failure to report a suspected case can result in civil penalties and potential criminal charges under RCW 16.36.
• Moving birds in violation of a quarantine or control zone order: Unauthorized movement of poultry out of a restricted zone is a serious violation that can result in both civil fines and criminal referral, and can accelerate disease spread, compounding liability.
• Obstructing a WSDA investigation: If you visit a farm and suspect birds there are infected with highly pathogenic avian influenza, you are required to stay on the farm and contact WSDA immediately. Leaving a premises when HPAI is suspected — or preventing WSDA access — can constitute obstruction.
• Importing birds without required permits or health certificates: The Washington State Veterinarian’s office requires permits and Certificates of Veterinary Inspection for all animals moved into the state. Bypassing this requirement is a direct violation of state import law.

If you receive a notice of a permit denial, revocation, or suspension from WSDA, you do have recourse. Upon notice by the Department to deny, revoke, or suspend a permit, a person may request a hearing under chapter 34.05 RCW. This administrative hearing process is your formal avenue to contest a WSDA enforcement action.

The best way to avoid penalties is straightforward: register your premises, practice consistent biosecurity, report sick birds without delay, and follow any movement restrictions issued by WSDA. Do not wait to report unusual signs of disease or unexpected deaths among your birds. Call your agricultural extension agent, local veterinarian, the WSDA State Veterinarian (1-360-902-1878), or the U.S. Department of Agriculture (USDA) Veterinary Services office. Early action protects your flock, your neighbors’ flocks, and your legal standing.

Washington’s regulatory framework for avian flu is built around speed and transparency. The rules are strict because the disease demands it — WSDA expects the disease will remain an ongoing risk for poultry in the state. Staying informed, staying registered, and staying in contact with WSDA when something looks wrong are the three habits that will keep you on the right side of every regulation covered here.
