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

Ohio sits at the center of one of the most active avian influenza zones in the United States. Ohio was the hardest-hit state by HPAI in 2025, having lost 14,728,900 commercial poultry birds — a staggering toll that reshaped how the state enforces poultry disease regulations. Whether you manage a commercial egg operation or keep a small backyard flock, understanding Ohio’s avian flu rules is not optional. It is your legal obligation and your flock’s best defense.

This guide breaks down every major regulation you need to follow as an Ohio poultry owner — from premises registration and biosecurity standards to reporting requirements, quarantine restrictions, and compensation rules. Keep this page bookmarked and check the Ohio Department of Agriculture (ODA) website regularly, as rules can change rapidly during active outbreaks.

HPAI vs. LPAI: Understanding Avian Flu Classifications in Ohio

Before you can navigate Ohio’s avian flu regulations, you need to understand the two primary classifications of avian influenza and why they carry very different regulatory consequences.

Avian influenzas are categorized based on the severity of the symptoms they cause in chickens. Low Pathogenic Avian Influenza (LPAI) viruses do not cause illness in poultry and are common in wild birds around the world. Highly Pathogenic Avian Influenza (HPAI), such as H5N1 detected in 2022, often causes death to poultry, though symptoms in other birds can vary.

The HPAI virus is the most contagious form of avian flu and is responsible for causing large-scale outbreaks in poultry operations. HPAI spreads rapidly among birds, resulting in large numbers of sick and dead birds within a few days after the initial outbreak. LPAI, by contrast, may cause only mild respiratory symptoms or a drop in egg production, and while it is reportable in Ohio, it triggers a less aggressive regulatory response than HPAI.

HPAI was confirmed or suspected in just over half of reported wildlife mortality events during the fall 2025–winter 2026 monitoring period, marking the fourth consecutive year that the virus has affected wild birds in North America. This strain of H5N1 first reappeared in late 2021 and has since spread across all four major migratory flyways — Atlantic, Central, Mississippi, and Pacific. Ohio sits directly within the Mississippi Flyway, making it one of the highest-risk states in the country during spring and fall migration seasons.

You should also be aware that HPAI does not usually spread directly from bird to human, but it can be transmitted through direct contact with infected birds or their environment. This is relevant not just for your flock’s health but for your own personal safety obligations under state and federal guidance.

Premises Registration Requirements for Poultry Owners in Ohio

Ohio requires poultry premises to be registered with the Ohio Department of Agriculture. This registration system is a cornerstone of the state’s disease surveillance and emergency response infrastructure. Without a registered premises ID, you cannot participate in indemnification programs, and state responders will have difficulty locating your operation quickly during an outbreak.

The National Premises Identification (PIN) system, administered at the state level through the ODA, applies to anyone keeping poultry — including backyard flock owners. Registration is done through the ODA’s Animal Health Division and assigns your property a unique identifier used for disease tracing, movement documentation, and emergency notifications.

• Commercial poultry operations are required to maintain active premises registration at all times.
• Backyard flock owners are strongly encouraged — and in many outbreak scenarios effectively required — to register in order to receive official quarantine notifications and compensation eligibility.
• Registration information must be kept current; changes in flock species, size, or ownership require an update to your premises record.
• Your premises ID number will be required on all movement documents, health certificates, and HPAI response paperwork.

Interest in keeping backyard poultry has been increasing steadily, with a huge jump in growth around the COVID pandemic and HPAI outbreaks due to egg price increases and egg shortages. This surge in backyard flocks has made premises registration even more critical, as small flocks can serve as disease bridges between wild birds and commercial operations. Many cities and municipalities in Ohio require a certification before they allow you to keep backyard poultry, so check both state and local requirements before starting your flock.

Biosecurity Requirements for Commercial and Backyard Flocks in Ohio

Biosecurity is the first and most important line of defense against avian flu in Ohio. The ODA and USDA have issued detailed biosecurity protocols that apply to all poultry owners, with more stringent requirements for commercial operations. Failing to maintain adequate biosecurity can expose you to regulatory penalties and, more importantly, leave your flock vulnerable to a disease that spreads with devastating speed.

According to the Ohio Department of Agriculture, best biosecurity practices for commercial poultry owners include preventing contact with wild birds and waterfowl, keeping birds indoors when possible, and adding wildlife management practices around your farm.

Additional ODA-recommended biosecurity measures include:

• Keeping visitors to a minimum — only allow those who care for your poultry to have contact with them, and make sure they follow biosecurity principles.
• Washing your hands before and after contact with live poultry using soap and water. If using a hand sanitizer, first remove manure, feathers, and other materials from your hands.
• Providing disposable boot covers (preferred) and/or disinfectant footbaths for anyone having contact with your flock. If using a footbath, remove all droppings, mud, or debris from boots and shoes using a long-handled brush before stepping in.
• Establishing a rodent and pest control program, and storing and maintaining feed, ingredients, bedding, and litter to limit exposure to and contamination from wild animals.

Sanitation efforts are a major part of changes being made in Ohio to prevent further outbreaks. Many farms are now set up with shower-in and shower-out facilities to protect birds. For commercial operations, the USDA’s APHIS Defend the Flock program provides free biosecurity assessments and resources.

Thoroughly washing hands with soap and water is a very effective way to inactivate any influenza virus, including HPAI H5N1. These viruses are also inactivated by many common disinfectants such as detergents, 10 percent household bleach, rubbing alcohol, and other commercial disinfectants. Make sure all disinfectants are applied at the correct dilution rates and contact times to be effective.

Reporting Sick or Dead Birds in Ohio

Ohio law requires you to report unusual illness or death in your flock promptly. This is not a suggestion — it is a legal obligation under the Ohio Revised Code and a critical part of the state’s ability to contain disease spread. Delays in reporting have been shown to dramatically increase the number of premises affected during an outbreak.

Here is who to contact and when:

1. Sick or dead poultry on your property: Contact the Ohio Department of Agriculture at agri.ohio.gov or 614-728-6220.
2. Sick or dead wild birds: Report to the Ohio Department of Natural Resources (ODNR) at 1-800-WILDLIFE.
3. After-hours emergencies: After-hour emergency calls regarding testing and sample submission can be made to the Animal Health After-Hours Line at (888) 456-3405.

You should report immediately if you observe any of the following in your flock:

• Sudden, unexplained death of multiple birds
• Significant drop in feed or water consumption
• Sudden decrease in egg production
• Respiratory distress, nasal discharge, or coughing
• Neurological signs such as lack of coordination, tremors, or twisted necks
• Swelling of the head, eyelids, comb, wattles, or hocks

When submitting samples to the Ohio Animal Disease Diagnostic Laboratory (ADDL), the ODA provides guidelines for submitting samples for Avian Influenza PCR testing. For gallinaceous birds such as chickens, turkeys, pheasants, and quail, oropharyngeal/tracheal swabs are recommended. For domestic waterfowl such as ducks and geese, cloacal swabs are used.

When submitting samples, let the Ohio ADDL know they are coming by calling 1-614-728-6220 or emailing submissions@agri.ohio.gov. Walk-ins are welcome Monday through Friday, 8:00 am to 5:00 pm.

Ohio’s Current HPAI Status and Active Outbreak Zones

Ohio experienced the most severe HPAI outbreak of any state in the country during 2025, and the threat remains ongoing as of mid-2026. Understanding the current outbreak landscape helps you assess your risk level and determine whether heightened precautions are warranted for your operation.

In 2025, 26 states lost commercial poultry or gamebird flocks to HPAI. According to data compiled by WATT Global Media from USDA APHIS records, 285 commercial flocks in the country were lost in 2025, and close to half of them were in Ohio and Indiana — 137 flocks combined.

No state lost more commercial flocks in 2025 than Ohio, which had 70 flocks infected. However, all 70 of those instances occurred during the first four months of the year. The types of flocks involved included commercial table egg layers, commercial meat turkeys, and commercial table egg layer pullets.

Ohio’s poultry industry was significantly impacted over the last several months in the western area of the state, particularly in Darke and Mercer counties. Mercer County had the most commercial poultry flocks affected by the virus in 2025, at 45 flocks.

As of the publication of this guide, the ODA maintains a live tracking map of active control areas and confirmed detections. The ODA website is kept up to date with information on detections, sample submission guidance, and biosecurity resources. On the web page, there is both a map of current active control areas under the “Take Action on HPAI” tab and a list of all detections under the “Tracking HPAI Across Ohio” tab. You should check this map regularly, especially during spring and fall migration seasons.

Wild birds in Ohio continue to be monitored for HPAI. The largest HPAI event involving black vultures in the Atlantic and Mississippi Flyways occurred in Ohio, where approximately 116 vultures died in late September 2025. Reports of sick or dead wild birds should go to the ODNR, not the ODA, as described in the reporting section above.

Poultry Movement and Quarantine Restrictions in Ohio

When HPAI is detected in Ohio, the ODA has authority to impose immediate movement restrictions on live birds, poultry products, and associated equipment within and around affected areas. These restrictions are among the most consequential regulations you will face as a poultry owner, and violating them carries serious legal consequences.

Ohio’s movement control framework operates on two levels: a federal control zone managed by USDA APHIS and a state-level quarantine or restricted zone managed by the ODA. Here is how each works:

A real-world example of how these restrictions work: The Ohio Department of Agriculture issued a proclamation imposing a temporary ban on the movement of live birds from non-commercial premises across 13 western Ohio counties. The decision came as HPAI continued to pose a significant threat to Ohio’s poultry industry, which ODA notes contributes $4.9 billion to the state’s economy and supports more than 16,000 jobs.

The ODA proclamation prohibited the movement of all live birds — including poultry, wild game birds, fancy poultry species, and exotic species — from non-commercial premises, including public and private shows, exhibitions, sales, and all activities involving these birds, in the affected counties. The restriction remained in effect until May 15, 2025.

Even outside of formal quarantine zones, you should be aware that:

• Interstate movement of poultry requires a Certificate of Veterinary Inspection (CVI) and may require negative AI test results.
• Moving birds to fairs, exhibitions, or sales requires compliance with ODA event biosecurity requirements and may be suspended entirely during active outbreaks.
• Vehicles and equipment that have been on an infected or quarantined premises must be cleaned and disinfected before leaving.
• Products from any HPAI-affected flocks are prohibited from entering the food system.

Flock Depopulation and Compensation Rules in Ohio

If HPAI is confirmed on your premises, the state and federal response will move quickly. Understanding what happens during depopulation — and what financial assistance you may be entitled to — can help you prepare before a crisis occurs.

After a case is detected, ODA and USDA staff work closely with the Ohio Poultry Association and poultry producers on the response, which includes depopulation, disposal, biosecurity audits, and environmental sampling of the premises.

Once disease is detected in a flock, it is “depopulated” — meaning all the animals are killed. This is a mandatory, non-negotiable step under both federal and Ohio law. The purpose is to eliminate the source of infection as rapidly as possible to protect surrounding operations.

USDA records show that between February 2022 and July 2024, infected farms containing 10,000 to 25,000 birds took an average of 1.86 days to depopulate, while farms of 1 million to 5.5 million birds took an average of 9.54 days. According to the USDA, depopulation delays may increase HPAI transmission risk, as viral particles continue to disperse into the environment. This is why having a written response plan prepared in advance is strongly encouraged by Ohio’s State Veterinarian.

Regarding compensation, the federal indemnification program is administered by USDA APHIS and covers the appraised value of depopulated birds and some associated costs. However, Ohio producers encountered significant challenges with this program during the 2024–2025 outbreak:

As a result of the outbreak and its impact on Ohio’s poultry industry, Governor Mike DeWine and Lt. Governor Jim Tressel asked USDA Secretary Brooke Rollins to support Ohio’s poultry farmers by backdating the effective date of USDA’s indemnification program. Governor DeWine noted that of the 74 confirmed cases in the past 13 weeks, only 3 would qualify for compensation based on the effective date.

The USDA’s $1 billion strategy to combat HPAI includes $500 million for ramped-up biosecurity to help keep HPAI from entering farms in the first place, and $400 million in financial relief for affected producers in the fiscal year. The agency is also exploring new programs to help farmers speed up repopulation, including ways to simplify the approval process to speed recovery.

After depopulation, your premises must go through a mandatory cleaning, disinfection, and downtime period before you can repopulate. The length of this period is determined by USDA APHIS in coordination with the ODA and is based on environmental sampling results from your premises.

Penalties for Non-Compliance in Ohio

Ohio takes avian flu regulation enforcement seriously, and the penalties for non-compliance are designed to reflect the severity of the risk that a single non-compliant operation poses to the entire industry. Violations can result in civil penalties, criminal charges, loss of compensation eligibility, and mandatory flock destruction at the owner’s expense.

Here is a breakdown of the primary compliance obligations and the consequences of violating them:

Under Ohio Revised Code Chapter 941, the ODA has broad authority to quarantine premises, restrict movement, and order the destruction of animals that are infected or exposed to a dangerous disease. Interference with an ODA inspector or veterinarian carrying out these duties is itself a separate violation.

It is also worth noting that HPAI spreads quickly and can be fatal to flocks and devastating to poultry owners. The ODA urges poultry owners to intensify biosecurity and best management practices — not just because it is required, but because prevention is far less costly than the consequences of an outbreak. The regulatory penalties described above are in addition to the economic losses from losing your flock, the emotional toll of depopulation, and the operational downtime required before you can repopulate.

For comparison, Ohio’s approach to regulating animal operations in other areas of agriculture follows a similar compliance-first philosophy. If you are interested in how regulatory frameworks apply to other animal-related activities in the region, you may find it useful to review horse boarding regulations in Wyoming or horse boarding regulations in Wisconsin for context on how states structure animal care compliance requirements.

Staying compliant with Ohio’s avian flu regulations is not just about avoiding fines — it is about protecting your livelihood, your neighbors’ flocks, and the broader agricultural economy that contributes $4.9 billion to Ohio’s economy and supports more than 16,000 jobs. Keep your premises registered, maintain your biosecurity protocols year-round, report any signs of illness immediately, and monitor the ODA’s active outbreak map every migration season. Those steps are your best protection against both the disease and the regulatory consequences that follow it.
