Coggins Test Requirements in Arkansas: What Every Horse Owner Must Know

Arkansas takes equine infectious anemia seriously — and the law reflects that. Whether you are buying a horse, hauling to a trail ride, or bringing an animal in from out of state, you are required to have documentation proving your horse has tested negative for EIA within the past 12 months. Failing to comply is not a minor oversight; it is a misdemeanor offense under Arkansas state law.

This guide walks you through every layer of Arkansas’s Coggins test requirements: which animals are covered, when testing is triggered, how the test works, what happens at the border, and what the consequences are if a horse tests positive or if you skip the paperwork altogether.

What Is Equine Infectious Anemia (EIA) and Why It Is Regulated in Arkansas

Equine infectious anemia is a blood-borne viral disease caused by equine infectious anemia virus (EIAV), a lentivirus in the family Retroviridae. EIA affects horses, mules, and donkeys, and spreads primarily through the bites of blood-feeding insects like horseflies and deerflies, as well as contaminated equipment such as needles and surgical tools.

Once infected, horses remain lifelong carriers of the virus. There is no cure for EIA, and although many infected horses show no symptoms, they remain contagious for life, endangering the health of other horses. The disease presents in three ways: acute cases involve high fever, weakness, swelling, and anemia; chronic cases bring intermittent fever, weight loss, and anemia; and inapparent carriers show no visible signs but remain contagious.

Arkansas has particular reason to enforce strict controls. EIA is also known as swamp fever because of its higher incidence in Gulf Coast states, where warm climates support large populations of blood-sucking insects that are the primary transmitters. Cases occur nationwide, but 80 percent are in the nine southeastern states. Historically, Arkansas ranked third in EIA incidence among all states in the reporting year ending October 1993, behind only Texas and Louisiana.

The Arkansas General Assembly determined that equine infectious anemia is significantly widespread and poses a serious threat to the equine population of the state, thereby threatening the livelihood of many citizens. That finding drove the passage of the state’s core EIA statute and has shaped every regulation that followed.

Key Insight: Because EIA has no cure and no approved vaccine in the United States, the Coggins test is the only tool available to identify and remove infected animals before they spread the virus to healthy herds.

Which Animals Require a Coggins Test in Arkansas

Arkansas law applies to the entire equidae family, not just horses. Any animal in the family Equidae — including horses, asses, mules, ponies, and zebras — falls under EIA testing requirements. Other livestock are not known to be affected by the EIA virus, so cattle, pigs, sheep, and goats are not subject to Coggins testing rules.

Every horse or other member of the equidae family that is sold, traded, exchanged, or otherwise involved in a change of ownership from one person, group, farm, corporation, association, or partnership to another must have been tested for equine infectious anemia within the preceding 12 months and must be accompanied by a certificate showing the animal was subjected to an official test with negative results.

The same 12-month testing standard applies when equines participate in congregating events. Arkansas Act 540 requires a Certified EIA Verifier to be present to check Coggins test papers at any equine event meeting one or more specified criteria. Those criteria include events that charge any fee of any kind (including entry, membership, camping, or grounds fees), events that provide prize money, trophies, ribbons, or awards of any kind, and events that cause a concentration of more than 50 equids.

In short, if your equine is being sold, traded, shown, raced, auctioned, or assembled with 50 or more other equines, a current negative Coggins certificate is required by Arkansas law. If you are unsure whether a specific event qualifies, contact the Arkansas Department of Agriculture Equine Programs office directly.

When a Coggins Test Is Required in Arkansas

The clearest trigger for a required Coggins test in Arkansas is a change of ownership. Every horse or other member of the equidae family that is sold, traded, exchanged, or otherwise involved in a change of ownership must have been tested within the preceding 12 months and must be accompanied by a certificate showing the test results were negative.

Beyond ownership transfers, testing is required before your horse participates in any qualifying congregating event — horse shows, trail rides, rodeos, livestock markets, and public auctions all fall within this category. It is the event sponsor’s responsibility to have a Certified EIA Verifier present for verification of Coggins tests. That means organizers share legal accountability alongside individual horse owners.

For horses entering Arkansas from another state, a negative EIA test within 12 months is required alongside a Certificate of Veterinary Inspection (CVI). The CVI and Coggins requirements work together — you need both documents for interstate movement, not just one. An Extended Equine Certificate of Veterinary Inspection (EECVI) is valid for six months from the inspection date or until the horse’s current EIA test expires, whichever comes first, since EIA tests are typically valid for 12 months from the blood draw date.

Pro Tip: Even if your horse never leaves your property, you still need a current negative Coggins certificate before selling or transferring ownership. Get the test done before you list the animal for sale so you are not scrambling at closing time.

How the Coggins Test Works and Approved Testing Methods in Arkansas

The Coggins test is a blood test that detects antibodies against the equine infectious anemia virus (EIAV). Developed in the 1970s by Dr. Leroy Coggins, it remains the gold standard for EIA diagnosis. A licensed, accredited veterinarian must draw the blood sample and submit it to an approved laboratory — you cannot self-collect or use an uncredentialed practitioner.

Two laboratory methods are approved for official EIA testing:

• AGID (Agar Gel Immunodiffusion): Results are returned in 24 to 48 hours. This is the original “Coggins test” method and remains the confirmatory standard.
• ELISA (Enzyme-Linked Immunosorbent Assay): This method is faster but requires AGID confirmation if the result is positive. A positive ELISA alone is not sufficient for a final diagnosis.

The ELISA test can detect antibodies earlier than the AGID test, but because it may produce false positive results, the confirmatory test for EIA is the AGID. Laboratories must use USDA-approved EIA test forms. Starting April 15, 2020, all veterinarians and laboratories must use USDA-approved EIA test forms; digital certificates that meet federal requirements include the statement “Official EIA Test Form, Approved by USDA Veterinary Services March 2020.”

The Arkansas Livestock and Poultry Commission recognizes all EIA test forms from other states that are considered official test forms in those respective states. The federal form VS 10-11 is the nationally recognized EIA test form for all states. Digital Coggins certificates are accepted in Arkansas and can be stored and presented electronically through platforms connected to USDA-approved laboratories.

One important timing note: when laboratory tests are performed before there has been sufficient time for antibody production against the virus — during the initial 45-day exposure period — false negatives can occur. If you suspect recent exposure, discuss retesting timing with your veterinarian before relying on a fresh test result.

Interstate Movement and Import Requirements in Arkansas

Horses entering Arkansas require a Certificate of Veterinary Inspection (CVI) and a negative EIA (Coggins) test within the past 12 months. Both documents must travel with the horse. The CVI confirms that a licensed veterinarian has inspected the animal and certified it meets Arkansas entry requirements; the Coggins certificate confirms the EIA test result specifically.

Arkansas participates in the Extended Equine Certificate of Veterinary Inspection (EECVI) program, which gives horse owners more flexibility for multi-trip travel. EECVIs function the same as regular health certificates but allow horse owners to move for up to six months. Prior to each movement under an EECVI, owners log in to their account, enter travel dates, origin, and destination, and confirm the horse is healthy. The system generates a Health Declaration and Movement Permit (HDMP) that serves as documentation when crossing state borders, and it must be kept together with the EIA/Coggins test for the EECVI to remain valid.

For identification purposes when using an EECVI, four forms of official ID are accepted: lifetime brand inspection, microchip, photo EIA/Coggins test, or EIA/Coggins accession number from a complete and legible test. Southern states, including Arkansas, typically accept either a microchip or a photo Coggins.

Document	Validity Period	Required For
Coggins Certificate (VS Form 10-11)	12 months from blood draw date	All interstate movement, sales, events
Certificate of Veterinary Inspection (CVI)	Typically 30 days from issue	Interstate entry into Arkansas
Extended Equine CVI (EECVI)	Up to 6 months (or until Coggins expires)	Multi-trip interstate movement

If you regularly haul horses across state lines for competitions or trail riding, the EECVI option can reduce paperwork significantly. Contact your accredited veterinarian to determine whether your horse qualifies and which identification method Arkansas will accept for your specific situation.

What Happens When a Horse Tests Positive in Arkansas

A positive EIA test result sets a formal regulatory process in motion. If any animal of the equidae family within Arkansas is found to be a reactor to the official test in Arkansas laboratories or out-of-state laboratories, the owner may request that an additional second test be administered to the animal within 30 days by any USDA-approved laboratory at the owner’s expense. This second test is the owner’s opportunity to challenge an initial positive result before permanent disposition decisions are made.

If the second test also returns positive, the animal is confirmed as a reactor and must be reported to state and federal animal health authorities. Cases must be reported to state and federal animal health authorities. The Arkansas Department of Agriculture will then initiate an investigation to determine which other equines may have been exposed.

The USDA and state animal health regulatory agencies require euthanasia or strict lifelong quarantine for horses testing positive for EIAV. Federal and state health agencies, as well as the American Association of Equine Practitioners, support euthanasia as the most prudent option, albeit a difficult one. Lifelong quarantine in a screened stall is another, less acceptable, alternative.

Arkansas law also provides a third option for confirmed reactors: the infected equidae may be sent with an accompanying official VS Form 1-27 certificate confining them to an approved equine slaughtering facility or to a livestock market for sale directly to a slaughtering facility to be destroyed. This option is rarely chosen but remains available under state statute.

Important Note: The 30-day window to request a second test is your only formal avenue to dispute an initial positive result. If you do not request the retest within that period, the initial positive stands and disposition requirements apply automatically.

Quarantine, Euthanasia, and Isolation Rules in Arkansas

If a horse is confirmed as an EIA reactor, the quarantine and isolation requirements are strict and non-negotiable. In the United States, if an equine tests positive for EIA, it must be separated and quarantined within 24 hours of receiving the positive test results and must be quarantined at least 200 yards away from other equine residents. This distance requirement is designed to reduce the risk of insect-borne transmission to nearby negative horses.

Horses testing positive for EIA are required by law to be permanently identified via branding or tattooing and to be quarantined. Transportation and housing are severely restricted, and owners who choose quarantine must post signs clearly stating the housing of a quarantined animal.

The fate of other horses on the same property is also regulated. If one animal tests positive, all other equine residents must be tested as well. They must remain in place and be considered under quarantine until they are confirmed free of EIA. No new residents should be introduced during this period, and they will need to be tested again 30 to 60 days after the initial positive test. Once everyone has tested negative for at least 60 days, they can be considered out of quarantine.

For owners who choose permanent quarantine over euthanasia, the practical challenges are substantial. You may find yourself unable to meet the 200-yard separation requirement, and if you cannot meet the stipulations, the government will likely require euthanasia. Infected horses will always pose a health risk to other horses, whether or not they show signs of illness, and even in the best management situations, blood-feeding insects cannot be totally controlled or eliminated.

Penalties for Non-Compliance in Arkansas

Arkansas treats EIA certification violations as criminal offenses, not civil infractions. Any person who sells or exchanges ownership of any equidae in this state without having the required certification; any person or chief official of a livestock market, public horse auction, or other sales event who sells or offers for sale equidae without proper certification; or any person or chief official of a horse show, trail ride, or other equidae congregating event who allows equidae to participate without certification, shall be guilty of a misdemeanor.

Upon conviction, a violator may be punished by a fine of not less than $200 nor more than $1,000, and each violation constitutes a separate offense. That last point matters: if you bring five untested horses to a horse show, you are not facing one charge — you are potentially facing five separate misdemeanor counts, each carrying its own fine.

Liability extends beyond individual horse owners. Event organizers and livestock market officials who knowingly allow non-compliant equines to participate face the same misdemeanor exposure. According to USDA Animal and Plant Health Inspection Service guidance, falsification of the Coggins form or knowingly using a falsified form is a criminal offense under federal law and may result in a fine or imprisonment. Forging or altering a Coggins certificate therefore carries consequences at both the state and federal level.

Beyond fines, non-compliance can expose you to civil liability if an undetected EIA-positive horse spreads the disease to another owner’s herd. Mandating proof of a negative Coggins test before travel or participating in an event helps prevent the spread of EIA across regions or among horse populations, protecting not only individual animals but also safeguarding economic interests. Skipping the test is not just a legal risk — it is a financial one as well.

Violation	Classification	Penalty Range
Selling/trading equine without Coggins certification	Misdemeanor	$200–$1,000 per offense
Allowing uncertified equine at a horse show or trail ride	Misdemeanor	$200–$1,000 per offense
Livestock market selling without certification	Misdemeanor	$200–$1,000 per offense
Falsifying or knowingly using a falsified Coggins form	Federal criminal offense	Fine and/or imprisonment

The simplest way to stay compliant is to schedule your horse’s annual Coggins test before the testing window expires, keep the certificate accessible whenever you haul, and verify that any horse you purchase comes with a current negative result. If you manage an event or operate a livestock market in Arkansas, confirm that your Certified EIA Verifier is on-site before the first horse arrives.
