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

South Carolina’s poultry industry is one of the most economically significant agricultural sectors in the Palmetto State — and it faces a persistent, evolving threat from avian influenza. Whether you raise a backyard flock of six hens or manage a commercial turkey operation, the rules governing how you prevent, detect, and respond to avian flu apply to you.

Understanding avian flu regulations in South Carolina is not just a legal obligation — it is your first line of defense against a disease that can wipe out an entire flock within days. This guide walks you through every major regulatory requirement, from how the two strains of the virus are classified to what compensation you can receive if the worst happens.

HPAI vs. LPAI: Understanding Avian Flu Classifications in South Carolina

Influenza in poultry falls into two groups: low pathogenic avian influenza (LPAI) and highly pathogenic avian influenza (HPAI). These two classifications are not just scientific labels — they determine which regulatory requirements apply to your flock, how authorities respond to a detection, and what trade and movement restrictions go into effect.

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. That mutation risk is exactly why South Carolina treats even low-pathogenic detections seriously.

Birds infected with LPAI usually experience only mild signs if any, including respiratory signs such as conjunctivitis and nasal discharge, ruffled feathers, or a drop in egg production. Because the symptoms are subtle, LPAI can spread quietly through a flock before you notice anything is wrong.

Unlike LPAI, the first indication of HPAI in poultry is sudden death, often without signs of illness. HPAI strains are deadly to domestic poultry and can wipe out entire flocks within a matter of days. HPAI is an extremely infectious and fatal form of the disease that, once established, can spread rapidly from flock to flock.

Avian-origin influenza viruses are broadly categorized based on a combination of two groups of proteins on the surface of the influenza A virus: hemagglutinin (“H” proteins, of which there are 16) and neuraminidase (“N” proteins, of which there are 9). Many different combinations are possible, and each combination is considered a different subtype. Avian influenza viruses are classified as either “low pathogenic” or “highly pathogenic” based on their genetic features and the severity of the disease they cause in poultry.

The currently circulating AI virus affecting birds and dairy cattle in the United States is an H5N1-type virus, a strain commonly reported in wild birds and recognized as the HPAI variety. Understanding this distinction matters because HPAI triggers mandatory depopulation, quarantine zones, and federal indemnity processes — while LPAI may allow for alternative control measures.

For a broader look at other avian diseases that can affect South Carolina bird populations, the articles on avian tuberculosis and avian chlamydiosis provide helpful context on the range of threats poultry owners face.

Premises Registration Requirements for Poultry Owners in South Carolina

One of the most important — and often overlooked — obligations for South Carolina poultry owners is premises registration. Registering your property with the state creates a critical communication link between you and animal health officials, so that if HPAI is detected nearby, authorities can reach you quickly.

The farm will be given an Official Premises ID number with Clemson University Livestock Poultry Health. This ID number is the foundation of South Carolina’s disease surveillance system. Without it, your flock is effectively invisible to the state’s early-warning network.

The South Carolina NPIP office certifies commercial and small poultry flocks through specific disease testing and sanitation, record and reporting requirements. Participation in the National Poultry Improvement Plan (NPIP) — administered in South Carolina through Clemson Livestock Poultry Health — is the primary pathway for formal premises registration and flock certification.

• NPIP Flock Number: The farm and breeding flock will be registered with the NPIP National Office to receive a NPIP Flock Number and listed in the national directory.
• Pullorum-Typhoid Testing: Poultry entering or leaving South Carolina or going to public exhibition must be tested negative for Pullorum-Typhoid.
• AI Clean Certification: If you also show or move birds or hatching eggs to North Carolina, Georgia, Florida, Virginia, Texas, or Pennsylvania, your flock will also need to become NPIP Avian Influenza (AI) Clean, since these states have avian influenza testing requirements.
• Interstate Movement: If you are moving hatching eggs, babies, or older birds across state lines, it is required to become NPIP Certified in order to meet the other state’s entry requirements and the Federal Interstate Movement Law requirements.
• Annual Inspections: As a NPIP Certified participant, your breeder birds will need to be tested for Pullorum-Typhoid every year and your premises inspected every year.

To reach the South Carolina NPIP office directly, the South Carolina NPIP Coordinator and Poultry Specialist Veterinarian is Julie Helm, DVM, DACVP, reachable at 803-726-7802 or jhelm@clemson.edu.

Birds either coming into SC or leaving SC need to be tested negative for two salmonella diseases of poultry called Pullorum and Typhoid, birds need to be individually identified with state-approved leg or wing bands, and need official movement documents.

Biosecurity Requirements for Commercial and Backyard Flocks in South Carolina

Biosecurity is the single most effective tool you have against avian flu. Clemson Livestock Poultry Health continues to work together with South Carolina’s poultry industry and other state and federal agencies to prepare for and respond to introductions of influenza in poultry. The state’s voluntary cooperative control plan includes education, monitoring, reporting, and response.

Avian influenza viruses spread through direct, bird-to-bird contact. They can also spread via contaminated surfaces or materials, such as manure; egg flats, crates, or other farming materials and equipment; and people’s clothing, shoes, or hands. That means biosecurity must address not just your birds, but everything and everyone that enters your property.

South Carolina State Veterinarian Michael Neault has stated that “poultry owners should take extra care to isolate domestic birds from wild waterfowl and from ponds, lakes and other water sources that wild birds may use.”

The USDA’s Defend the Flock program provides a detailed framework that South Carolina producers are encouraged to follow. Core biosecurity practices include:

• Keep it Clean: Clean cages and coops. Clean any equipment before it comes onto your property. Wear designated farm shoes and clothing to care for your birds. Wash your hands before and after working with your birds.
• Isolate wild bird contact: Keep domestic poultry away from waterfowl and any water sources frequented by migratory birds.
• Control vehicle traffic: Wash your vehicles and trailers after visiting other poultry facilities and before you come home.
• Monitor daily: Change birds’ food and water daily and observe your flock for any behavioral or physical changes.
• Restrict visitor access: Limit who enters your poultry areas and require all visitors to follow the same biosecurity protocols you use.

For commercial operations, biosecurity requirements are directly tied to compensation eligibility. Producers must provide, as a condition for receiving indemnity payments, 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.

A final federal rule amended regulations to require biosecurity plan audits. Specifically, facilities subject to these provisions must have their biosecurity plans audited at least once every two years.

Bring home only hatching eggs or day-old poultry to replenish or start a flock, preferably from an AI-clean, NPIP participant. Do not bring home adult birds. Low-path AI was spread in previous outbreaks by trading and selling adult birds between backyard flocks.

South Carolina’s wild bird populations — including the owls and hawks found across the state — are generally not direct vectors, but waterfowl and shorebirds are. Keeping your flock separated from any wild bird contact is the most important single step you can take.

Reporting Sick or Dead Birds in South Carolina

Speed is everything when it comes to avian flu containment. The faster you report, the faster authorities can respond — and the more birds (and farms) can be protected. South Carolina law requires that both LPAI and HPAI be reported to the State Veterinarian’s office.

To report sick or dead poultry in South Carolina, call 803-788-2260 Monday through Friday, 8:00 AM to 4:30 PM, or use the online report form. To report sick or dead wild waterfowl, call the SC Department of Natural Resources at 803-734-3886.

Testing for influenza in poultry is conducted at the Clemson Veterinary Diagnostic Center in Columbia. Commercial and non-commercial poultry flocks are routinely monitored for influenza.

Knowing what to look for is essential. Signs that should prompt an immediate report include:

• Sudden, unexplained death — especially multiple birds in a short period
• Lethargy, lack of appetite, decreased egg production, soft-shelled or misshapen eggs, purple discoloration of wattles, comb, and legs; runny nose, difficulty breathing, coughing, sneezing, diarrhea, and swelling of the head, comb, eyelid, wattles, and hocks.
• Any significant and unexplained drop in feed or water consumption

Producers or owners who suspect an animal disease should contact their veterinarian to evaluate the animal or herd. Your veterinarian can initiate the formal reporting chain and coordinate with Clemson Livestock Poultry Health on your behalf.

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. Delayed reporting does not just risk your neighbors’ flocks — it can cost you compensation for birds that die before officials can assess them.

Birds that sing at night or behave abnormally can sometimes signal environmental stressors — but sudden daytime lethargy and death in your flock is a different matter entirely.

South Carolina’s Current HPAI Status and Active Outbreak Zones

South Carolina has not been immune to the ongoing national HPAI outbreak that began in February 2022. HPAI was detected again in wild birds in the United States in January 2022, when USDA APHIS identified an H5N1 strain of HPAI in a wild bird in South Carolina — making the state one of the first points of entry for the current outbreak wave.

For the first time during the 2022–2026 North American HPAI outbreak, a commercial poultry flock in South Carolina was hit by the virus. USDA APHIS confirmed the presence of HPAI in a commercial meat turkey flock in Lee County on February 23, 2026. There were 36,000 turkeys involved.

Until that point, the state’s only instance of HPAI in a commercial operation was when a commercial upland gamebird flock in Spartanburg County was struck on the final day of 2024. The state also had five non-commercial flocks struck by HPAI from 2022 to 2025.

The North Carolina Department of Agriculture reported on January 6, 2026, that a backyard flock in Franklin County tested positive for HPAI. In addition, the Georgia Department of Agriculture reported confirmed cases in commercial poultry facilities in January 2026. These neighboring-state detections significantly elevated the risk level for South Carolina producers.

While state-by-state wild bird detection numbers fluctuate due to migration patterns, significant detections of the H5N1 strain continued into early 2026, with thousands of wild birds affected nationwide as of January.

There have been no human cases of Highly Pathogenic Avian Influenza (H5N1) in South Carolina since it was first detected in the United States in 2022. The CDC and South Carolina DPH assess the risk of H5N1 avian influenza to the public as low.

South Carolina DPH continues to work closely with the State Veterinarian at Clemson University’s Livestock Poultry Health Division, the South Carolina Department of Natural Resources, the Centers for Disease Control and Prevention, and USDA APHIS as they monitor for any new cases of this virus.

Poultry Movement and Quarantine Restrictions in South Carolina

Movement restrictions are one of the most powerful tools available to stop HPAI from spreading between properties and across county or state lines. South Carolina’s State Veterinarian has authority to impose both statewide importation restrictions and localized quarantine zones when the situation warrants.

The State Veterinarian’s office is temporarily prohibiting importation of backyard poultry, waterfowl, and ratites (e.g., emu, ostrich, rhea) from counties with confirmed infections of HPAI for public sales, exhibitions, and expositions under SC Code of Laws section § 47-4-30.

Public sale, exhibition, and exposition of backyard poultry, waterfowl, and ratites from counties without cases of HPAI infections may continue with normal business operations following South Carolina Code of State Regulations § 27-1014 – Importation of Poultry and South Carolina Code of State Regulations § 27-1027 – Importation of Ratites.

When a confirmed HPAI case is identified on a specific premises, a more localized control zone is established:

1. Infected Premises Quarantine: Premises infected with HPAI are placed under quarantine, prohibiting the movement of poultry and poultry products on or off of the infected site.
2. 10 km Control Zone: A 10 km zone is established around infected flocks. Within this zone, animal health officials work to identify premises with commercial and backyard poultry. Poultry flocks inside of the control area undergo surveillance in accordance with USDA protocols.
3. Movement Permitting: All poultry producers in the control area must comply with stringent biosecurity and permitting protocols in order to move poultry or poultry products off of their farms.

The State Veterinarian’s office strongly recommends that all producers review the specific restrictions that markets, shows, and exhibitions may implement in addition to or in tandem with state restrictions prior to bringing birds.

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.

Flock Depopulation and Compensation Rules in South Carolina

If HPAI is confirmed on your property, depopulation is mandatory — and it happens fast. Understanding the process in advance helps you act quickly and protect your eligibility for compensation.

There is no treatment for HPAI. The only way to stop the disease is to depopulate all affected and exposed poultry. The USDA works with infected flock owners to develop a flock plan which includes appraisal and indemnity agreements for depopulation of poultry that remain on the premises.

After depopulation of the flock, all poultry carcasses on the infected farms are composted inside of the barns or buried with approval of SC DHEC. DHEC also regulates the disposal of HPAI-infected flocks.

On the compensation side, both USDA and South Carolina have structured processes to help you recover losses:

USDA covers the cost of depopulating and disposing of HPAI-affected flocks. In most cases, USDA or its contractors carry out these activities and pay the costs directly. If you choose to manage your own depopulation, USDA will reimburse you according to a financial plan at a rate equal to what would otherwise be paid to a contractor for the same work.

From February 2022 to February 2025, APHIS committed a total of $1.811 billion for HPAI response activities. Producers who meet biosecurity plan requirements and pass audits are eligible to access this federal support.

Penalties for Non-Compliance in South Carolina

South Carolina takes avian flu compliance seriously, and failure to follow state and federal regulations can carry significant consequences — both financial and legal. Non-compliance not only puts your flock at risk; it can expose neighboring operations to disease and eliminate your eligibility for any government assistance.

The key areas where non-compliance penalties apply include:

• Failure to Report: Both LPAI and HPAI are reportable diseases under South Carolina law. Failing to report a known or suspected case is a violation of state animal health statutes. Animal health professionals — including veterinarians, diagnostic laboratories, and public health personnel — are required to 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.
• Illegal Movement of Birds: Moving poultry from HPAI-affected counties into South Carolina for sales or exhibitions violates SC Code of Laws § 47-4-30. Violations can result in civil penalties and seizure of birds.
• Biosecurity Plan Non-Compliance: APHIS is establishing requirements for certain poultry premises to complete a biosecurity audit as a condition for receiving indemnity payments for poultry depopulated because of an outbreak of HPAI. Failing a biosecurity audit or not having a documented plan in place at the time of an HPAI detection can result in denial of indemnity payments.
• Quarantine Violations: Premises infected with HPAI are placed under quarantine, prohibiting the movement of poultry and poultry products on or off of the infected site. Violating a quarantine order is a serious federal and state offense.

When a South Carolina premises is identified with HPAI, on-the-ground response efforts begin immediately. Animal health officials carry out a number of activities according to protocols established by USDA. During an HPAI event, DHEC will coordinate with animal health agencies and the poultry industry to identify, protect, and monitor the health of poultry workers and responders in direct contact with HPAI-infected birds.

Beyond formal penalties, non-compliance carries a practical cost: unregistered premises are not in the state’s notification network, meaning you may not receive timely alerts about outbreaks in your area. Registering your premises and following biosecurity protocols is both a legal requirement and a sound business decision.

South Carolina’s poultry sector shares the landscape with a wide variety of wildlife. Staying informed about the animals on and around your property — from snakes to bats — helps you understand which species interact with your flock environment and where biosecurity gaps might exist. Waterfowl and shorebirds remain the primary wild vectors for HPAI, but a well-maintained, wildlife-aware operation is your best protection across the board.

For additional regulatory context in neighboring states, the guide on bass fishing regulations in North Carolina and fly fishing regulations in North Carolina illustrate how regional wildlife management frameworks operate across the Carolinas — a useful backdrop for understanding how interstate animal health coordination works.

The bottom line: avian flu regulations in South Carolina exist to protect your flock, your neighbors’ flocks, and the state’s broader agricultural economy. Registering your premises, maintaining a documented biosecurity plan, reporting sick birds immediately, and staying current on outbreak zone information are the four pillars of compliance — and the four most effective actions you can take to keep your birds healthy.
