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

Delaware sits at the heart of one of the most productive poultry regions in the United States, and that distinction comes with serious regulatory responsibility. When highly pathogenic avian influenza sweeps through a flock, the consequences — mass depopulation, quarantine zones, and financial losses — can unfold within days.

If you keep poultry in Delaware, whether you manage a commercial broiler operation or a small backyard flock, understanding the state’s avian flu regulations is not optional. This guide walks you through every major rule, from how the virus is classified to what happens if you fail to comply.

HPAI vs. LPAI: Understanding Avian Flu Classifications in Delaware

Avian influenza is a contagious viral disease of domestic and wild birds and a major threat to the poultry industry, animal health, trade, and the economy worldwide. It is caused by influenza type A viruses, and the disease varies in severity depending on the strain and species affected. Understanding the two primary classifications — HPAI and LPAI — is the foundation of every regulatory response in Delaware.

Highly pathogenic avian influenza (HPAI) strains are deadly to domestic poultry and can wipe out entire flocks within a matter of days. The H5N1 strain has driven the most significant outbreaks in Delaware and across the U.S. in recent years. Low pathogenicity avian influenza (LPAI) strains, by contrast, typically cause few or no signs of illness. They occur naturally in wild birds around the world, but some LPAI strains can become highly pathogenic in poultry.

Each virus combination is considered a different subtype and can be further broken down into different strains that circulate within flyways and geographic regions. Avian influenza viruses are further classified by their pathogenicity — the ability of a particular virus strain to produce disease in domestic poultry.

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.

Premises Registration Requirements for Poultry Owners in Delaware

One of the most fundamental obligations for any poultry owner in Delaware is registering your premises with the state. This requirement applies whether you keep a few backyard hens or operate a large-scale commercial broiler house.

The Delaware Department of Agriculture requires the registration of all locations where live poultry is kept, which allows timely information on disease incidents to be sent to all poultry producers. Registration forms are available online at https://de.gov/poultry.

Registration serves a critical surveillance function. The Delaware Department of Agriculture, with the help of the University of Delaware laboratory system, performs active surveillance and testing of birds for avian influenza within the state every day. Surveillance is conducted at commercial poultry operations, exhibition and backyard flocks, and at livestock and poultry auctions. Without a registered premises, you cannot be included in this alert network — meaning you could miss urgent disease notifications affecting your area.

• Registration is required for all locations where live poultry is kept, regardless of flock size
• Forms are available online through the Delaware Department of Agriculture at de.gov/poultry
• Registered owners receive timely disease incident notifications
• Registration enables DDA to conduct targeted surveillance at your premises
• Commercial operations must also comply with the National Poultry Improvement Plan (NPIP) requirements

If you own or manage poultry in Delaware and have not yet registered your premises, visit the Delaware Department of Agriculture’s Avian Influenza Information Center or contact the Poultry and Animal Health Section at (302) 698-4500. You can also learn about related avian diseases like tuberculosis and avian chlamydiosis that require similar vigilance from flock owners.

Biosecurity Requirements for Commercial and Backyard Flocks in Delaware

Biosecurity is the single most effective tool available to Delaware poultry owners for preventing HPAI from reaching their birds. Both commercial producers and backyard flock owners are expected to follow specific protocols, and during active outbreak periods, the DDA may issue heightened biosecurity orders that carry the force of law.

On January 7, 2025, the Delaware Department of Agriculture issued Heightened Biosecurity Protocols Involving Delaware Poultry Farms. On January 8, 2025, the DDA issued a Control Order Requiring Specific Handling, Transport, and Storage of Poultry Litter Due to Highly Pathogenic Avian Influenza. These orders illustrate that biosecurity rules in Delaware are not merely advisory — they can become enforceable mandates during outbreak events.

Avian influenza is a highly contagious airborne respiratory virus that spreads quickly among birds through nasal and eye secretions and manure. The virus can be spread from flock to flock, including flocks of wild birds, through contact with infected poultry, equipment, and the clothing and shoes of caretakers.

The following biosecurity practices are expected of all Delaware poultry owners:

1. Exclude wild birds from flock areas. Keep your birds away from spaces where migratory waterfowl or wild birds have access, particularly during fall and spring migration seasons.
2. Disinfect all equipment and vehicles. All vehicles, crates, coops, and footwear must be in a completely clean condition before being used to load poultry from a Delaware farm. DDA personnel have the authority to inspect all vehicles and equipment prior to entry to a Delaware farm.
3. Control farm access. Limit visitors to essential personnel only. Limit, monitor, and record any movement of people, vehicles, or animals on or off your farm using a log book.
4. Isolate new or sick birds. It is recommended to quarantine newly arrived birds for at least 30 days before mixing them into an existing flock.
5. Change clothing and wash hands. When you, your employees, or family members have been to other farms or places where there are livestock or poultry, clean and disinfect your vehicle tires and equipment before returning home. Ensure you change your clothes and wash your hands before rejoining your flock.
6. Avoid sharing equipment. Avoid sharing equipment, tools, or supplies with nearby farms or other owners of livestock or poultry. If sharing becomes necessary, thoroughly clean and disinfect the items before bringing them back to your own property.

For backyard flock owners specifically, the DDA advises keeping birds in covered outdoor coops to prevent contact with wild birds. Backyard flock owners should keep birds in outdoor coops and not bring birds that have been living outside into the home. Children and pets should be kept away from wild birds and bird droppings.

You can explore additional biosecurity measures from University of Maryland Extension and the USDA-APHIS avian influenza resource hub for detailed guidance on protecting your flock.

Reporting Sick or Dead Birds in Delaware

Prompt reporting is one of your most important legal and civic obligations as a poultry owner in Delaware. Delaying a report when birds show signs of HPAI can allow the virus to spread to neighboring farms and wild bird populations, compounding losses across the region.

The reporting process differs depending on whether you operate a commercial or backyard flock:

For backyard flock owners: Delaware backyard flock owners who notice any unusual symptoms in their flock should email poultry.health@delaware.gov or call the Delaware Poultry Health Hotline at 302-698-4507 and provide their contact information, size of flock, location, and concerns.

For commercial producers: Commercial poultry producers should follow the procedures of contacting the company they grow for when they notice signs of disease. Your integrator company has established protocols that feed directly into the state and federal reporting system.

For dead wild birds: If Delaware residents see a sick or dead bird, they should report sightings through the DNREC Division of Fish and Wildlife’s sick and injured wildlife reporting form. The Delmarva Chicken Association also advises that in Delaware, you can call DNREC at 302-735-3600 (Ext. 2) or use the Wildlife Mortality Survey form to report dead waterfowl or raptors to DNREC.

Signs that should trigger an immediate report include:

• Sudden, unexplained death in multiple birds
• Severe or rapid respiratory distress
• Swelling around the head, neck, or legs
• Decreased water or feed consumption, increased mortality, nasal discharge, or lack of energy
• Significant drop in egg production without other explanation

If you or anyone working with your flock develops flu-like symptoms after contact with poultry, contact 888-295-5156 (after hours) or 302-744-4990 (business hours) for a referral to a DPH clinic to obtain a flu swab.

Delaware’s Current HPAI Status and Active Outbreak Zones

Delaware has experienced repeated HPAI detections in recent years, and the 2025–26 waterfowl migratory season brought new confirmed cases to the state. Staying current on active outbreak zones is essential for adjusting your biosecurity posture and understanding any movement restrictions that may apply to your operation.

In the winter of 2024–2025, several thousand snow geese and other wild birds died throughout the state, and multiple poultry producers were affected. The outbreak prompted a wave of state control orders and heightened biosecurity mandates across the Delmarva Peninsula.

The 2025–26 season brought additional confirmed cases. The Delaware Department of Agriculture announced in November 2025 that testing of a Kent County backyard poultry flock returned presumptive positive for H5 HPAI. That was the first Delaware detection of avian influenza during the 2025–26 waterfowl migratory season.

Commercial flocks were soon affected as well. What was earlier reported as a presumed positive outbreak of HPAI in a commercial broiler flock in Delaware was confirmed by USDA-APHIS on January 13, 2026. The affected flock included 147,900 broilers and is located in Kent County. Earlier in 2026, another Kent County broiler flock was hit by HPAI, with 32,800 birds involved.

Looking at the broader recent history: Delaware had three commercial poultry flocks affected by HPAI in 2025 that collectively involved 465,600 birds. Delaware also had three commercial poultry flocks struck by HPAI in 2022, but the state was spared of any cases in 2023 and 2024.

Detections are higher in the fall and spring, because wild birds continue spreading the virus as they migrate to their seasonal homes. Delaware’s position along the Atlantic Flyway makes it particularly vulnerable during these migration windows. 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.

For real-time HPAI detection data across the U.S., you can consult the USDA-APHIS confirmed flock detection tracker. You may also find it useful to review how neighboring states handle similar regulatory frameworks, such as Virginia’s animal and natural resource regulations.

Poultry Movement and Quarantine Restrictions in Delaware

Movement restrictions are among the most operationally impactful regulations a Delaware poultry owner can face. When HPAI is detected, the state and federal governments impose strict controls on where birds, equipment, and byproducts can travel — and violations carry serious consequences.

When serious, highly contagious diseases are diagnosed, the State Veterinarian, through the authority of the Secretary of Agriculture, may quarantine the animal, herd, or flock to prevent the spread of disease to other premises. This authority is exercised rapidly once a presumptive positive is identified.

Live poultry and other avian species originating from an area that is under quarantine for an infectious disease may not move within Delaware or enter the State of Delaware without an official movement permit approved in advance by the Delaware State Veterinarian. This applies to birds moving both intrastate and interstate.

Additional movement rules under Delaware’s Poultry Disease Prevention Regulations include:

• Poultry transported out of the state for the purpose of sale or change of ownership and brought back into Delaware is prohibited and will result in the quarantine and possible destruction of the entire flock.
• Complete and accurate records must be maintained including the name, address, and telephone number of the purchaser, the number, species, and weight of the poultry sold, and the date of the sale. These records, invoices, or receipts must be retained for at least one year.
• It is the responsibility of the owner of the birds to obtain all pertinent information from the state of destination regarding any health diagnostic testing or inspection requirements that must be fulfilled prior to the birds leaving Delaware. Furthermore, it is the owner’s responsibility to make the necessary arrangements with the approved diagnostic laboratory, accredited veterinarian, or other persons needed to provide the official documentation required.

At the federal level, under current USDA-APHIS policies, when an HPAI case is discovered, all poultry farms located within a 10-kilometer radius of the case are banned from placing flocks until the virus is contained. This control zone approach means your operation can be restricted even if your own birds have not tested positive.

The Delmarva Chicken Association offers a control area release FAQ and movement permit guidance specifically tailored for Delmarva producers navigating HPAI restrictions.

Flock Depopulation and Compensation Rules in Delaware

If your flock tests positive for HPAI, depopulation will follow quickly. This is a difficult but legally mandated process designed to prevent further spread of the virus. Understanding both the depopulation procedure and the compensation pathway available to you can help you prepare for the worst-case scenario.

Because bird flu can be very deadly in poultry, all bird flocks on an affected farm are likely to be depopulated under federal and state policy to prevent the avian influenza virus from spreading. This is an unfortunate but necessary measure when dealing with catastrophic diseases like HPAI. This process is carried out using approved veterinary protocols. All methods are carried out with guidance from USDA, state animal health officials, and poultry veterinarians.

After depopulation, carcass disposal follows a regulated composting process. After the flocks are depopulated, the carcasses will be composted. For broiler chickens, they will be composted in the poultry house itself. Composting is the method used for normal poultry mortality, though on a smaller scale. Like any composting, this process will raise the heat to 130 degrees Fahrenheit for sufficient time to kill the virus. Once the compost has been sufficiently heated, it can be removed from the house and disposed of in a variety of ways.

On the compensation side, USDA-APHIS provides indemnity and compensation to producers to remove animals APHIS classifies as affected, suspect, or exposed to diseases of concern, and to eliminate dangerous viruses from the environment. When a farm is identified as a premises with HPAI, a case manager will be assigned to help the producer navigate the indemnity process.

However, a significant gap in the current compensation framework has drawn attention from Delaware’s congressional delegation. The program currently only compensates farmers whose flocks test positive, not those in the control area who are disallowed from placing flocks until the virus is contained, which sometimes takes months. In response, U.S. Senators Chris Coons (D-Del.) and Roger Wicker (R-Miss.) introduced the Healthy Poultry Assistance and Indemnification Act (HPAI Act) to ensure that all poultry growers and laying operations in HPAI control areas whose operations are affected receive compensation.

A proposed improvement to the compensation calculation would make payments more transparent: payments to farmers would be calculated based on the average income they earned from the last five flocks. This method is more transparent and ensures that farmers will not face a cash shortfall in the face of an HPAI outbreak in their area.

Penalties for Non-Compliance in Delaware

Delaware’s poultry disease prevention regulations are backed by enforceable legal penalties. Failing to follow premises registration requirements, movement restrictions, biosecurity orders, or reporting obligations can result in civil penalties, forced quarantine, and even the destruction of your flock at your expense.

The legal foundation for Delaware’s poultry regulations is found in Title 3 of the Delaware Administrative Code. Failure to comply with these regulations may result in the assessment of a civil penalty. No civil penalty shall be imposed until an administrative hearing is held before the Secretary of Agriculture or his or her designee.

The administrative hearing process follows a defined timeline: administrative hearings for violations shall be conducted within 30 days of the violation. The Department shall issue a decision in writing to the person charged with a violation within 30 days of the conclusion of the administrative hearing.

Movement violations carry particularly severe consequences. Poultry transported out of the state for the purpose of sale or change of ownership and brought back into Delaware is prohibited and will result in the quarantine and possible destruction of the entire flock and penalties as described in the regulation.

Key compliance obligations that carry penalty risk include:

• Failing to register your premises — required for all locations where live poultry is kept
• Moving poultry without a permit from a quarantined area without prior approval from the Delaware State Veterinarian
• Violating control orders — such as the poultry litter handling and transport order issued in January 2025
• Failing to maintain movement records — sales records must be retained for at least one year
• Allowing uninspected vehicles on farm — DDA personnel have authority to inspect vehicles and equipment before farm entry
• Failing to report suspected HPAI signs in your flock in a timely manner

For the full text of Delaware’s Poultry Disease Prevention Regulations, visit the Delaware Administrative Code, Title 3, Section 901. For questions about specific compliance obligations, contact the Delaware Department of Agriculture’s Poultry and Animal Health Section directly at (302) 698-4500 or email DEanimalhealth@delaware.gov.

Staying compliant is not just about avoiding penalties — it is about protecting your operation, your neighbors’ operations, and Delaware’s broader agricultural economy. Poultry owners who stay registered, follow biosecurity protocols, and report promptly are the first line of defense against an outbreak that can affect the entire Delmarva region.
