Coggins Test Requirements in New Jersey: What Every Horse Owner Must Know

If you own, transport, or sell horses in New Jersey, the Coggins test is not optional — it is a legal requirement that carries real consequences for non-compliance. An EIA (Equine Infectious Anemia) test, commonly known as a Coggins test, is a blood test that determines whether a horse is carrying EIA, a viral and deadly disease among equines. New Jersey enforces this requirement under the authority of the New Jersey Department of Agriculture (NJDA) and aligns with federal USDA standards to protect the state’s equine population.

Whether you are heading to a show, crossing state lines, buying a new horse, or simply moving an animal on a public road, understanding when and how the Coggins test applies in New Jersey keeps you on the right side of the law. This guide walks you through every aspect of the state’s EIA testing rules, from which animals are covered to what happens when a test comes back positive.

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

Equine infectious anemia (EIA) is a bloodborne infectious disease of equids caused by Lentivirus equinfane. Clinical outcomes range from a subclinical carrier state to a range of clinical signs of variable severity, including fever, depression, thrombocytopenia, anemia, jaundice, dependent edema, increased heart and respiration rates, hemorrhages on mucous membranes, epistaxis, muscle weakness, and collapse, as well as death in a small percentage of cases.

Most often, horses with EIA are asymptomatic carriers — showing no signs or symptoms — which is one of the reasons testing is so important. An infected horse that looks completely healthy can still spread the virus to every animal in the same pasture or barn.

Infected horses remain infected for life, there is no preventive vaccine and no curative treatment. EIA is a reportable disease regulated by the United States Department of Agriculture (USDA) and state animal health regulatory agencies. Because the disease is incurable and horses become permanent carriers, New Jersey — like every other state — relies on mandatory testing as the primary tool for keeping EIA out of the general horse population.

In nature, equine infectious anemia virus (EIAV) is a vector-transmitted disease. Blood-feeding insects transfer virus-infective blood between horses. Horse flies, deer flies, and stable flies are the most common vectors. Other modes of transmission include re-used needles, blood-to-blood contact, or semen. New Jersey’s warm summer months create ideal conditions for these insect vectors, making annual testing especially relevant in the state.

Key Insight: EIA poses no risk to humans. There is no evidence that equine infectious anemia is a zoonotic risk. The regulation exists entirely to protect equine health and the broader horse industry.

Which Animals Require a Coggins Test in New Jersey

New Jersey’s EIA testing rules apply broadly across the equine family. Any animal in the Family Equidae — including horses, asses, mules, ponies, and zebras — falls under these regulations. If you own any of these animals and plan to move them, sell them, or bring them to a public event in New Jersey, a valid negative Coggins certificate is required.

The requirement extends to animals entering competitive or public settings. No horse shall enter the grounds of any track association absent presentation of a valid certificate of a negative Coggins test. The same principle applies at equine shows, fairs, exhibitions, and sales where multiple horses from different premises come into contact.

There are two narrow exceptions under New Jersey rules. Any horse claimed in a claiming race conducted by a race track licensed by the New Jersey State Racing Commission is exempt from retesting, so long as that horse and all other horses admitted to the track have been tested and found negative for EIA within 24 months before the date of the claim. Additionally, equidae being imported for immediate slaughter or veterinary care do not require a negative test for EIA.

When a Coggins Test Is Required in New Jersey

New Jersey triggers the Coggins test requirement in several distinct situations. Knowing each one prevents you from being caught off guard at a show gate, a state border, or a sale barn.

• Road travel: By New Jersey law, any horses traveling on state roads must have proof of a negative Coggins within the past 24 months.
• Health certificates for travel: NJ state law requires all animals to be examined within 30 days of writing the health certificate. The animal must be determined to be free of disease, have a normal rectal temperature, and have proof of a negative Coggins test within the past 12 months.
• Race track entry: No horse shall enter the grounds of any track association without a valid certificate of a negative Coggins test. The certificate must indicate the test was performed within one year prior to the date of presentation to the racing secretary and that it was conducted by a laboratory approved by the United States Department of Agriculture.
• Change of ownership: A negative EIA test is required any time a horse changes hands in New Jersey. The transferor must deliver to the transferee an unaltered copy of the official test report either personally or by certified mail.
• Shows and exhibitions: Officials at most every event or show will ask to see a copy of your horse’s current negative Coggins test and/or a certificate of veterinary inspection (CVI).

Pro Tip: Keep a physical and digital copy of your horse’s Coggins certificate at all times during transport. Ensure the Coggins test details match the Certificate of Veterinary Inspection exactly — if the Coggins says “Star, Strip, Snip” and your CVI says “Blaze,” you risk rejection. Make sure to list the Coggins number, lab, date, and result on the CVI.

How the Coggins Test Works and Approved Testing Methods in New Jersey

To perform a Coggins test, a licensed veterinarian must draw blood from the horse and send it to an accredited lab for analysis. The lab will conduct a test to detect the EIA antibody — a protein that allows the body to recognize the EIA virus, which will only be present if the horse has had the EIA virus. The lab then provides either a positive or negative test result back to the veterinarian, who shares it with the horse owner.

Two types of diagnostic tests are approved by the USDA for diagnosis of EIAV: the agar gel immunodiffusion (AGID) test and several enzyme-linked immunosorbent assay (ELISA) tests. The AGID test, commonly known as the Coggins test, is the most widely used tool for diagnosing equine infectious anemia. The Coggins test is highly specific and 95% accurate but may occasionally yield a false-negative result.

ELISA tests are popular for their simplicity and rapid results. They are more sensitive than the AGID but may occasionally yield false-positive results. All ELISA positive tests must be confirmed with an AGID test. In practice, this means a positive ELISA result is not the final word — the Coggins (AGID) test serves as the definitive confirmation.

In New Jersey, the NJDA Animal Health Diagnostic Laboratory (AHDL) is the primary state-approved testing facility. Samples may be submitted to the AHDL either on VS 10-11 form “Equine Infectious Anemia Laboratory Test” or digitally using USDA’s online program or GlobalVetLink’s online program. Accurate and detailed identification of the equine, the owner, and the submitting veterinarian is required.

Only a Category II federally accredited veterinarian, state animal health official, or federal animal health official may submit samples for EIA testing. You cannot self-collect a blood sample and submit it independently. The test must be initiated by a qualified veterinarian every time.

Regarding result delivery, the NJDA recently updated its process. Effective June 1, 2026, only scanned VS 10-11 EIA forms are distributed through the online portal. Original VS 10-11 Coggins result forms will only be mailed upon request. If you want all your original paper Coggins test results mailed to you, call the lab to confirm your choice.

Test Type	Common Name	Speed	Accuracy	Confirmatory Role
Agar Gel Immunodiffusion (AGID)	Coggins Test	Slower (days)	Highly specific, ~95%	Official confirmatory standard
Enzyme-Linked Immunosorbent Assay (ELISA)	ELISA / EIA Screen	Faster	More sensitive, may produce false positives	Screening only; positive must be confirmed by AGID

Interstate Movement and Import Requirements in New Jersey

Moving horses across state lines into or out of New Jersey adds another layer of documentation beyond the standard intrastate Coggins requirement. Proof of a negative EIA test performed at an accredited laboratory is required for entry into all 50 states. New Jersey is no exception, and the state actively enforces these requirements at the point of entry.

When importing horses into New Jersey from another state, you need both a valid Coggins certificate and a Certificate of Veterinary Inspection (CVI). Health certificates are required for any horse traveling out of the state and out of the country. Some shows within the state may require a health certificate or health statement in order to enter the show grounds.

In general, Coggins papers are valid for up to one year; however, some states or shows may require a negative Coggins test within six months of the event or transportation. In addition to Coggins papers, a CVI (Certificate of Veterinary Inspection), or horse health certificate is also required when transporting horses. Always verify the destination state’s specific requirements before you travel, as they may differ from New Jersey’s rules.

For frequent interstate travelers, a multi-state permit option exists. Many neighboring states have formed reciprocal livestock health arrangements so people who travel frequently with their horses between states can obtain an “equine passport” or equine interstate event permit (EIEP). Horse owners in the mid-Atlantic states and the South have the option of getting an EIEP that is good for six months and includes 15 states, from Texas to Virginia, as well as New York. New Jersey horse owners who regularly cross state lines for competitions should explore this option with their veterinarian.

If you need to move a horse that lacks a current negative EIA test for any reason other than slaughter or emergency veterinary care, you must obtain advance authorization. Any movement or transfer without a negative test requires advance authorization from the State Veterinarian. The animal’s custodian must always possess written prior authorization during movement. Contact the NJDA Division of Animal Health before attempting any such movement.

Important Note: State import requirements change faster than most people expect. Start your research at InterstateLivestock.com. If you are unsure, call the receiving state vet’s office — they would much rather answer a quick question than handle an illegal entry at the border.

What Happens When a Horse Tests Positive in New Jersey

A positive EIA result is a serious regulatory event that triggers an immediate response from state and federal animal health authorities. There is no cure for equine infectious anemia. Although most infected horses show no symptoms, they remain infectious for life, endangering the health of other horses. For this reason, the USDA and state animal health regulatory agencies require euthanasia or strict lifelong quarantine for horses testing positive for EIA.

When a positive result is confirmed, the NJDA Division of Animal Health is notified and will contact the horse owner directly. The veterinarian who conducted the test is also required to report the result. The positive horse is immediately placed under a regulatory hold — it cannot be moved, sold, or transferred without explicit authorization from the State Veterinarian.

Horses and other equids that have been in close contact with the confirmed positive animal are considered exposed and must be tested. Exposed equines will be quarantined and tested, and be subject to a retest 45–60 days after the removal of the EIA-positive horse. Quarantine will remain in effect until negative retest results are received.

If your horse tests positive for EIA, your options are limited. 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. The American Association of Equine Practitioners’ full disease guidelines are available through the AAEP EIA Disease Guidelines.

Quarantine, Euthanasia, and Isolation Rules in New Jersey

The quarantine and isolation standards for EIA-positive horses in New Jersey align with the USDA’s national framework. A confirmed EIA-positive equid must be euthanized or quarantined for life 200 yards away from any EIA-negative equid, as per USDA EIA program rules. This 200-yard distance is not arbitrary — it reflects the maximum flight range of the biting insects that transmit the virus between horses.

EIA-positive horses will always pose an unnecessary health risk to other horses, whether or not they show signs of illness. Even in the best management situations, blood-sucking insects cannot be totally controlled or eliminated. The only way to eradicate the disease is to eliminate the carriers.

If the owner elects lifelong quarantine instead of euthanasia, strict conditions apply. Horses testing positive for EIA are required by law to be permanently identified via branding or tattooing and to be quarantined. The quarantine facility must be screened to prevent insect contact and must maintain the 200-yard separation from all EIA-negative equids at all times. The NJDA will conduct follow-up inspections to verify compliance.

For horses on the same premises that were potentially exposed — but have not yet tested positive — a specific retesting protocol applies. These animals are quarantined in place and retested at 45–60 days after the positive horse is removed or euthanized. Potentially exposed horses that initially test negative for EIA will remain under quarantine until their 60-day retest, as per USDA program requirements. Only after a clean retest result can the quarantine be lifted.

Penalties for Non-Compliance in New Jersey

Failing to comply with New Jersey’s EIA testing requirements carries significant regulatory and legal consequences. The state enforces these rules through the NJDA Division of Animal Health under N.J.A.C. 2:5 (Quarantines and Embargos on Animals) and N.J.A.C. 2:3 (Livestock and Poultry Import regulations).

At race tracks, the penalty framework is clear. The trainer of a horse which races in violation of the Coggins test rule without evidence of a negative Coggins test and/or a vaccination for equine encephalitis is subject to the penalties provided for in the racing rules. This can include fines, suspension of racing privileges, and disqualification of the animal from competition.

Under New Jersey’s broader animal health statutes, knowingly exposing other animals to a horse with a contagious or infectious disease constitutes a violation that can trigger civil and criminal penalties. New Jersey law explicitly prohibits using or exposing a horse with an infectious disease dangerous to the health or life of animals, and violations carry fines ranging from $250 to $5,000 depending on the nature and severity of the offense, per the Animal Protection Laws of New Jersey.

Beyond fines, non-compliant owners may face:

• Mandatory quarantine of the entire premises at the owner’s expense
• Seizure of animals by the NJDA under quarantine and embargo authority
• Denial of entry to any licensed equine event, show, or race track in the state
• Rejection of interstate health certificates, blocking movement to other states
• Potential criminal charges if a non-compliant horse knowingly infects other animals

The most cost-effective way to avoid all of these outcomes is straightforward: schedule an annual Coggins test with a NJDA-accredited veterinarian, keep your paperwork current, and verify requirements before any transport or event. For horse owners who also deal with other animal health compliance in New Jersey, it is worth reviewing the state’s rabies vaccine requirements and related regulations to maintain full compliance across all animals on your property.

Pro Tip: Require proof of a negative Coggins test for horses coming onto your farm and/or interacting with your horse. Quarantine new horses entering the premises for at least 14 days after arrival, evaluating them for signs of illness during that time. Require proof of a negative Coggins test for horses you are considering buying or breeding. These biosecurity habits protect your herd and keep you legally covered.

Staying current with EIA testing is one of the most straightforward responsibilities of horse ownership in New Jersey. The test is inexpensive relative to the cost of a disease outbreak, the regulatory penalties, or the loss of an animal. Work with a licensed, federally accredited veterinarian, keep your Coggins certificates organized, and always check requirements before moving horses across state lines.
