Livestock Biosecurity Requirements in North Dakota Every Producer Should Know

North Dakota is one of the most livestock-dense states in the country, with more than 1.83 million beef cattle and calves spread across every county in the state. That scale means a single disease event — whether foot-and-mouth, highly pathogenic avian influenza (HPAI), or another contagious illness — can ripple through the agricultural economy with devastating speed.

Understanding and following livestock biosecurity requirements in North Dakota is not optional for producers who want to protect their herds, stay compliant with state law, and keep their operations running during a disease event. This guide walks you through every major requirement and best practice, section by section, so you know exactly what is expected of you.

What Is Livestock Biosecurity and Why It Matters in North Dakota

Biosecurity is the combination of practices and protocols designed to keep disease out of your operation and prevent it from spreading if it does get in. The term “bio” means life and “security” means safety or protection, so biosecurity means “protecting life” — and it includes measures to prevent disease introduction into a healthy population of animals as well as steps to limit the spread of a disease should it be introduced.

In practical terms, biosecurity operates on two levels. External biosecurity refers to procedures and practices that reduce the transmission of pathogens from sources off your farm, including the management of routine visitors such as milk trucks, feed deliveries, custom harvesters, and borrowed equipment, as well as bought or leased animals. Internal biosecurity refers to procedures and practices on the farm to prevent transmission of pathogens between areas of your own operation.

North Dakota’s geography makes these concerns especially acute. The state lies within a primary migration corridor for waterfowl, with millions of birds migrating through it each year. HPAI is shed in feces and respiratory secretions and can survive for extended periods in cool, damp conditions — making spring and fall migration especially high-risk times for animal owners. Beyond avian disease, the state’s large cattle, swine, and sheep populations mean that any breach in biosecurity can quickly affect neighboring operations.

“Biosecurity is not a single action — it’s a system of daily management practices that create a clear line of separation between healthy animals and potential disease threats,” explains Mary Keena, NDSU Extension livestock environmental management specialist. Treating it as a system — rather than a checklist you complete once — is the foundation of everything that follows.

Premises Registration and Identification Requirements in North Dakota

Before you can participate in the state’s animal health tracking system, your operation must be formally registered. The North Dakota Department of Agriculture (NDDA) uses a location premises registration system that assigns a unique identifier to each livestock site. This registration is the foundation of traceability — it allows state officials to quickly identify which premises may have been exposed during a disease investigation.

You can submit a Location (Premises) Registration form directly through the NDDA. The form captures contact information for your livestock business entity, which may be different from the location where the animals are actually kept. Make sure the physical address and GPS coordinates of the primary animal housing location are accurate, as this is what emergency responders and investigators will use.

Animal identification requirements vary by species. Cattle entering the state must be officially identified by a method approved by the state veterinarian, though feeder heifers, feeder steers, and spayed heifers are exempt from identification rules unless they are dairy source or exhibition or rodeo animals. For cattle coming from foreign countries, permanent official identification is required under a method prescribed by the state veterinarian.

For non-traditional livestock, identification obligations are more extensive. Inventory reports for nontraditional livestock are due on January 31st of each year. Any change of animal identification must be reported on the annual inventory report. Poultry dealers face their own registration layer: the North Dakota Board of Animal Health has implemented a registration requirement for all poultry dealers in the state, and all retail stores selling chicks are considered poultry dealers.

You can learn more about how identification intersects with animal movement in our guide on brand inspection requirements in North Dakota, which covers the branding and inspection rules that apply when cattle change ownership or cross state lines.

Biosecurity Plan Requirements in North Dakota

North Dakota does not currently mandate a written biosecurity plan for all general livestock producers under a single statewide statute. However, having a documented plan is strongly advised by both the NDDA and NDSU Extension — and for certain regulated operations, documentation becomes effectively required. “Creating and consistently following a strong biosecurity plan is the best defense poultry and dairy owners have against HPAI,” says Dr. Jake Galbreath, NDSU Extension veterinarian.

A well-constructed plan should address both external and internal disease pathways. Writing down a specific protocol and set of practices is essential — you, your employees, and everyone else that visits your farm needs to have something they can reference. Even if the protocol is simple, write it down. Consider making materials that are visual reminders to yourself and staff, such as signs and posters.

The NDDA’s biosecurity page provides access to biosecurity templates and continuity of business planning resources, including templates from the Secure Food Supply program. The goal of biosecurity is to protect people, animals, and plants from diseases and contaminants, and taking basic precautions can keep people and animals healthy — common-sense steps prevent contamination and the spread of diseases.

Your plan should be built around the following core components:

• Disease risk assessment: Identify which diseases are most relevant to your species and region
• Clean/dirty line designation: Clearly define where the biosecure zone begins and ends on your premises
• Standard operating procedures: Written protocols for animal entry, visitor access, equipment cleaning, and dead animal disposal
• Emergency contacts: Veterinarian, state veterinarian’s office, and NDDA contact information
• Record-keeping: Logs of animal movement, visitor entries, and sanitation events

Your veterinarian is one of the only people you work with that can comment on your entire system and how everything works together. They have specific biosecurity training that can help you develop a plan that targets your most significant transmission risks.

For dairy operations specifically, the Secure Milk Supply (SMS) Plan offers a continuity-of-business framework. The SMS Plan is a voluntary program to help dairy producers prepare before an outbreak of foot-and-mouth disease — it can better position dairy operations with cattle that have no evidence of infection to limit exposure of animals through enhanced biosecurity and move raw milk to processing under a movement permit issued by regulatory officials.

Animal Isolation and Movement Control Requirements in North Dakota

Controlling when and how animals move — both onto your premises and between locations — is one of the most regulated aspects of livestock biosecurity in North Dakota. The state’s rules are enforced by the North Dakota State Board of Animal Health and carry real legal consequences for non-compliance.

No animal or poultry that is infected with, or has been recently exposed to, any infectious or transmissible disease shall be imported into this state. This prohibition applies regardless of species or purpose.

Certificates of veterinary inspection (CVI) are required on most animals imported into North Dakota. The certificate must be made on official state or federal forms and contain names and addresses of consignor and consignee, with an accurate description and identification of all animals. A CVI documents that the animal is free of signs of infectious, contagious disease and has met the health requirements set by the State Board of Animal Health for import into North Dakota.

For cattle, additional testing is required for certain categories of breeding animals. Veterinarians signing CVIs for breeding-age bulls entering the state must certify either a series of negative Trichomonas foetus culture tests or a qualifying PCR test result within 60 days prior to entry with no female contact since the qualifying test.

Once new animals arrive on your premises, isolation is a mandatory practice. Isolate new animals for a period specified by a veterinarian. In practice, NDSU Extension guidance for poultry operations recommends a minimum 30-day quarantine period. New birds should be kept separate from a flock for at least 30 days. During isolation, the new animals should have no shared airspace, water, feed, or direct contact with your existing herd or flock.

Importation permits are required on certain animals entering North Dakota and can be obtained by calling the State Board of Animal Health at 701-328-2655 during business hours. The North Dakota State Board of Animal Health plans to step up surveillance and enforcement of animal movement regulations at fairs and events in 2026.

For cattle leaving and returning to the state, cattle leaving the state for exhibition or competition with a valid certificate of veterinary inspection may return to the state with the same certificate of veterinary inspection if the animal has not been out of the state for more than thirty days.

Visitor, Vehicle, and Equipment Sanitation Rules in North Dakota

Every person, vehicle, and piece of equipment that enters your livestock area is a potential disease vector. North Dakota biosecurity guidance treats visitor and equipment management as one of the highest-priority layers of protection — and with good reason. A single contaminated truck tire or a pair of boots worn at another farm can introduce pathogens that no vaccine can prevent.

NDSU Extension’s recommended protocols, issued as recently as March 2026, are clear on what you should require of anyone entering your operation:

1. Change clothing and footwear before entering the livestock area. Change clothing, wash hands, and disinfect footwear before and after handling animals.
2. Restrict nonessential access. Restrict access to livestock areas and minimize nonessential visitors.
3. Clean and disinfect vehicles. Clean and disinfect tools, equipment, and vehicles that travel between farms.
4. Do not share equipment between operations. Do not borrow disease from a neighbor — do not share lawn and garden equipment, tools, or bird supplies with a neighbor or other flock owners.
5. Establish a clean/dirty line. Designate a clear boundary between the biosecure area and the outside world, and enforce it consistently for every visitor.

For hunters and anyone who spends time in fields or wetlands, the risk of cross-contamination is especially high during fall and spring migration seasons. After walking in fields or wetlands while hunting, change clothing and footwear before crossing the clean/dirty line to care for animals. Do not walk through or drive trucks, tractors, or equipment through areas where waterfowl or other wildlife feces may be — and if unavoidable, clean shoes, vehicles, and equipment thoroughly to prevent transferring disease.

For operations that receive regular service vehicles such as feed delivery trucks, milk haulers, or custom harvesters, designate a specific entry and exit route that minimizes contact with animal housing areas. Post sanitation requirements at the entrance to your property so all visitors are aware of your protocols before they step out of their vehicles. You can find guidance on effective disinfectants and appropriate contact times for specific animal diseases through the NDSU Animal Biosecurity resource page.

Wildlife and Pest Control Obligations in North Dakota

North Dakota’s position in a major waterfowl flyway means that wildlife contact with your livestock is not a hypothetical risk — it is a seasonal certainty. HPAI is shed in feces and respiratory secretions and can survive for extended periods in cool, damp conditions, making spring and fall migration especially high-risk times for animal owners. Managing wildlife interaction is therefore a core biosecurity obligation, not an optional enhancement.

The NDDA and NDSU Extension recommend the following wildlife and pest management practices for all livestock producers:

• Limit contact between domestic animals and wild birds by housing animals when possible, and eliminate spilled feed that would attract wildlife.
• Do not allow poultry and livestock to share water sources, feedstuffs, or living environments with each other or wildlife.
• Reduce the attractiveness for wildlife by cleaning up litter and spilled feed around domestic animal housing.
• If anyone comes in contact with or handles wildlife, change into clean clothes, wash hands, and disinfect footwear before contact with domestic animals.
• Seal gaps in poultry houses, barns, and feed storage areas that could allow rodents, wild birds, or other animals to enter.
• Use physical barriers such as netting or enclosed runs to prevent wild bird access to poultry enclosures during migration peaks.

For rodent and pest control, the goal is to eliminate harborage and food sources. Keep feed in sealed, rodent-proof containers and remove standing water that could attract insects or waterfowl. Tall grass and brush piles near animal housing should be cleared regularly, as these areas shelter rodents and other pests that can carry disease.

If possible, keep animals housed until the risk for transmission has decreased. Nonlethal methods to deter wildlife are available on the USDA Wildlife Services website.

When sick or dead wildlife is found on or near your premises, report it immediately. Producers who observe unusual illness or unexplained deaths in poultry or dairy animals are encouraged to contact their veterinarian or the North Dakota State Veterinarian’s Office at 701-328-2655. You can also report sick or dead wildlife online. Direct wild bird avian influenza questions to the North Dakota Game and Fish Department at 701-204-2161.

Understanding the wildlife species that share your landscape helps you assess risk more accurately. Our articles on types of flies in North Dakota and types of bats in North Dakota cover common pest and wildlife species that producers should be aware of, including those with known disease transmission potential.

Dead Animal Disposal Requirements in North Dakota

Proper disposal of livestock carcasses is both a biosecurity necessity and a legal requirement in North Dakota. A dead animal left exposed on your property can attract scavengers, contaminate water sources, and serve as a reservoir for the same pathogens that killed the animal in the first place. Prompt and compliant disposal is one of the most direct ways you can prevent disease spread.

North Dakota Century Code Chapter 36-14 governs the disposition of animal carcasses, particularly those dying from contagious or infectious diseases. Under this statute, if burial of the animal is permitted, the burial may be made upon the premises of the owner or person in charge of the animal at any place more than one thousand feet (304.8 meters) from any dwelling house or barn.

If you fail to properly dispose of a carcass, the state has authority to act on your behalf and charge you for the cost. If the owner or person in charge of a dead animal fails to comply with the provisions of the statute, the overseer of highways shall comply with those provisions for the owner or person. The owner is liable to the county for any amount paid out for disposal services, and if the owner does not pay that amount within thirty days after written demand, the sum may be recovered in a civil action, with the judgment including the costs of the suit and a reasonable attorney’s fee.

Approved disposal methods in North Dakota generally include:

• Burial: Must meet the 1,000-foot setback from dwellings and barns; check with your county for additional depth and groundwater requirements
• Rendering: Contracting with a licensed renderer is one of the cleanest and most biosecure options, as it removes the carcass from your premises entirely
• Composting: On-site composting can be effective when done correctly; follow NDSU Extension guidelines for temperature, carbon-to-nitrogen ratios, and containment
• Incineration: Permitted in some jurisdictions; check local ordinances and air quality regulations before using this method

For poultry operations, the NDDA provides a dedicated checklist for cleaning and disinfecting poultry enclosures following a disease event. After any mortality event — especially one involving unexplained or sudden deaths — a thorough cleaning and disinfection of the affected housing area must precede the reintroduction of any new birds. One of the first clinical signs of HPAI is sudden unexplained death, and most HPAI cases report a decline in water and feed consumption prior to the unexplained death. If you observe these signs, contact your veterinarian immediately rather than waiting to see if the situation resolves.

Record-keeping is an important companion to disposal. Document the date of death, species, estimated weight, disposal method used, and location. This information is essential if a disease investigation is opened and can also support insurance or indemnity claims under federal programs.

For a broader look at how compliance requirements connect across animal operations in the region, see our guides on brand inspection requirements in North Dakota and the related rules for livestock trailer transport in neighboring states such as Nevada, Wisconsin, and Pennsylvania, which are relevant if you ship animals across state lines.

Staying compliant with North Dakota’s livestock biosecurity requirements is ultimately about protecting your investment, your neighbors’ operations, and the state’s agricultural economy. The rules around premises registration, animal identification, movement documentation, sanitation, wildlife management, and carcass disposal form a connected system — and a weakness in any one area creates vulnerability across all the others. Work with your veterinarian to develop a written biosecurity plan, keep your premises registration current, and treat every animal entry and every visitor as a potential disease risk that deserves a documented response.
