Livestock Biosecurity Requirements in Nevada: What Every Producer Needs to Know

Nevada’s wide-open rangelands and diverse livestock operations make the state a vital part of the western agricultural economy — and a place where a single disease outbreak can ripple across millions of acres and hundreds of herds in a matter of days.

If you raise cattle, sheep, goats, swine, horses, or poultry in Nevada, understanding your biosecurity obligations is not optional. It is the foundation of protecting your animals, your operation, and your neighbors. This guide walks you through every major livestock biosecurity requirement in Nevada, from premises registration to dead animal disposal, so you know exactly what is expected of you under state law and best-practice guidance.

What Is Livestock Biosecurity and Why It Matters in Nevada

Livestock biosecurity is the set of practices and measures aimed at protecting livestock from infectious diseases, pests, and contaminants. It involves preventing the spread of diseases on farms and ranches and between farms and ranches, as well as limiting the introduction of pathogens from outside sources. For Nevada producers, that definition carries real weight.

Stopping livestock movements in Nevada could be very challenging for livestock producers, particularly in the spring and fall when cattle typically ship out of state to new pastures and feeding locations. A foreign animal disease outbreak could trigger stop-movement orders that shut down those seasonal operations entirely — unless you have an approved plan in place.

Routine biosecurity is a cornerstone of livestock production systems — including poultry — to maintain food safety and security, protect the environment, and facilitate continuity of business by protecting animals and animal products. As a producer, this is your responsibility and your best option to prevent and reduce the risk of disease in your operation.

Nevada’s livestock industry faces a specific and acute threat from Foreign Animal Diseases (FADs). The University of Nevada, Reno Extension strives to increase producer awareness of the importance of biosecurity to protect livestock from disease, reduce the risk of disease transmission, minimize economic losses, and ensure food safety for consumers — with particular emphasis on the need for enhanced biosecurity measures given the acute risk of Foreign Animal Disease, including Foot and Mouth Disease.

You can learn more about Nevada-specific livestock movement rules by reviewing livestock trailer requirements in Nevada, which often intersect with biosecurity obligations during transport.

Premises Registration and Identification Requirements in Nevada

One of the most important — and most overlooked — steps you can take as a Nevada livestock producer is registering your premises and obtaining a national Premises Identification Number (PIN). This single action unlocks your ability to request movement permits, apply for indemnity, and participate in state and federal disease response programs.

A premises is any physical location where livestock and poultry animals are managed, including all locations where livestock are born, raised, marketed, or exhibited. A PIN is a unique number permanently assigned to a single physical location known as a premises — which also includes other locations associated with animal agriculture such as feed stores, feed mills, livestock markets, or exhibitions.

PINs are used by animal health officials for animal disease traceability and emergency response. They are required by producers to request movement permits during a disease outbreak or to apply for indemnity. In Nevada, the PIN is issued by the State Animal Health Official — the state veterinarian — through the Nevada Department of Agriculture (NDA).

Having contingency plans in place, establishing premises identification numbers (PINs) for traceability, and completing an approved enhanced biosecurity plan allows you to obtain livestock movement permits if your animals are not infected.

• Register your premises with the NDA’s Division of Animal Industry at agri.nv.gov or by calling (775) 353-3709
• Each physical location where you manage livestock requires its own unique PIN
• The number of livestock is not required to register for a PIN — only whether livestock are present, or that the premises is involved with the livestock industry, is recorded.
• Keep your PIN on file and include it on all official documents, health certificates, and movement permit applications

Nevada also maintains a robust livestock identification and brand inspection system. Reviewing the brand inspection requirements in Nevada alongside your premises registration will help you stay fully compliant with the NDA’s identification framework.

Biosecurity Plan Requirements in Nevada

Nevada operates on two tiers of biosecurity planning: routine (basic) biosecurity and enhanced biosecurity. Both are important, but they serve different purposes and carry different legal and operational consequences.

Routine Biosecurity Planning

Implementing basic or routine biosecurity plans involves applying specific tasks and practices in your day-to-day operations that provide the foundation for protecting animal health and well-being, as well as managing risks to your business. Nevada livestock producers practice routine biosecurity daily, from changing boots between barns, to handwashing, cleaning and disinfecting equipment, and quarantining new animals coming onto the farm and ranch.

However, routine plans alone are not sufficient in a crisis. Routine biosecurity programs will be insufficient to obtain movement permits during a foot-and-mouth disease outbreak — that will require an approved enhanced biosecurity plan.

Enhanced Biosecurity Planning

Enhanced biosecurity planning includes additional measures to prepare for future outbreaks of foreign animal diseases, such as foot-and-mouth disease. Such an outbreak would result in extraordinary measures taken by federal and state agencies to stop and limit animal movement, determine the extent of the disease in the U.S., stop its spread, and eliminate it from the U.S., if possible.

There are three major actions that all livestock operations should implement prior to an outbreak of foot-and-mouth disease in the U.S.: designate a biosecurity manager who develops the biosecurity plan with assistance from a veterinarian prior to an outbreak; complete a written operation-specific enhanced biosecurity plan; and obtain a national Premises Identification Number (PIN) issued by the State Animal Health Official.

Enhanced biosecurity plans can be reviewed and approved ahead of time by the Nevada Department of Agriculture state veterinarian. Once approved, livestock producers would be able to apply for movement permits, even if there is a stop-movement order in place.

In Nevada, Gary McCuin, Extension’s agricultural and natural resource advisor in Eureka County, and Tracy Shane, Extension’s state livestock specialist, have been trained in enhanced biosecurity planning by ASI and the Secure Sheep and Wool Supply Program. They are available to help Nevada livestock producers write individualized enhanced biosecurity plans to enable movement permits and continuity of operations during a foot-and-mouth disease or foreign animal disease outbreak.

Animal Isolation and Movement Control Requirements in Nevada

Controlling how and when animals move — both onto your premises and off of it — is one of the most direct ways you reduce disease risk. Nevada law sets specific requirements for animal movement, quarantine, and entry that you must follow.

Quarantine of New and Incoming Animals

Isolating newly acquired animals before introducing them to your existing herd or flock is a foundational biosecurity practice. Consider isolation of animals that have moved onto the holding before these are introduced to the rest of the herd or flock. This isolation period gives you time to observe animals for signs of illness and confirm health certificate compliance before any contact occurs.

Under Nevada law, animals infected with or exposed to disease are subject to strict movement controls. Removal of a quarantined or infected animal or animal product is prohibited without a permit from the State Quarantine Officer. If you discover a sick animal, do not move it off your premises without first contacting the NDA.

Entry Requirements for Incoming Livestock

Nevada imposes specific health and testing requirements on livestock entering the state. All horses, cattle, swine, sheep, and goats from a state where Vesicular Stomatitis Virus (VSV) has been diagnosed, or visiting an infected state and then returning to Nevada, except those moving directly to slaughter, must be accompanied by a Certificate of Veterinary Inspection (CVI) that includes a statement confirming the animals are free from signs of VSV.

For cattle and bison, brucellosis requirements are particularly detailed:

• Female cattle or bison that are at least 4 months of age and not more than 12 months of age must be vaccinated for brucellosis before any change of ownership occurs in Nevada, unless the cattle or bison are sold and immediately transported to a qualified feedlot.
• Sexually intact cattle or bison of any age moving from a Designated Brucellosis Surveillance Area (DSA) require a negative brucellosis test within 30 days prior to entry into Nevada.
• All bison, regardless of state of origin, that are 12 months and older must have a negative TB and brucellosis test within 30 days prior to entry.

For sheep, all sheep need to be officially identified with scrapie tags, and all scrapie tags need to be listed on the health certificate.

Livestock in Transit

Any class of livestock covered by the regulations on entry of foreign livestock may pass through the state in a railroad car or truck without restriction, if no part of the shipment is diverted within this state or unloaded for feed and rest for not more than 48 hours. If the livestock is held at any point within this state for more than 48 hours, immediate notice must be sent to the Administrator.

Proper trailer sanitation during transport is also a compliance requirement. For a full overview of transport-related rules, see livestock trailer requirements in Wisconsin and livestock trailer requirements in Pennsylvania for comparison with how neighboring states approach transport biosecurity.

Visitor, Vehicle, and Equipment Sanitation Rules in Nevada

Every person, vehicle, and piece of equipment that enters your operation is a potential disease vector. Nevada’s biosecurity framework — and the enhanced biosecurity plan template used by the NDA — addresses access control as a critical layer of protection.

Access Control Fundamentals

Key aspects of livestock biosecurity include access control: restricting access to farms, minimizing contact between livestock and people or animals that could carry diseases, and ensuring visitors follow strict hygiene protocols.

Your routine biosecurity plan should establish a clear access policy. Practical steps include:

• Provide signage indicating where vehicles can or cannot go, especially around livestock areas, and instruct and supervise visitors on biosecurity requirements with clear signage.
• When appropriate, provide PPE such as foot covers and coveralls, provide facilities for handwashing, and provide facilities for cleansing and disinfection of vehicles.
• Minimize the number of vehicles and people on site to essential only, and ensure all contractors — including veterinarians, AI technicians, foot trimmers, shearers, and staff — have clean clothes, vehicles, and equipment before handling livestock.

Conveyance Sanitation Under Nevada Law

Nevada law directly addresses the sanitation of livestock transport vehicles. An owner or operator of a conveyance used for transporting livestock shall maintain the conveyance in a sanitary condition. If a conveyance is used to transport livestock infected with or exposed to an infectious disease, the owner or operator must have the conveyance cleaned and disinfected if so ordered by the Administrator.

When disease is confirmed on a premises, Nevada’s administrative code requires thorough decontamination. All troughs and other feeding and watering appliances must be emptied. All litter, garbage, manure, and other organic material must be removed from floors, posts, and other parts of the equipment, and handled in such a manner as not to allow contact with any animals. All surfaces must be cleaned with water and detergent, and the entire surface of the equipment, fencing, troughs, chutes, floors, walls, and all other parts of the facilities must be saturated with an approved disinfectant.

Wildlife and Pest Control Obligations in Nevada

Nevada’s vast public lands and diverse wildlife populations create unique biosecurity challenges that producers in other states may not face at the same scale. Wildlife can transmit diseases including brucellosis, tuberculosis, and foot-and-mouth disease to domestic livestock — making wildlife and pest management a legal and operational obligation, not just a best practice.

Wildlife Interaction Risks

Nevada’s livestock operations frequently border or overlap with public lands managed by the Bureau of Land Management and the U.S. Forest Service. The University of Nevada, Reno Extension works to help producers voluntarily prepare for and defend against an outbreak to provide for continuity of business for the livestock industry in the advent of an FMD outbreak regardless of whether they operate solely on private land or also on public lands. This acknowledgment of public-land operations underscores why wildlife contact management is built into Nevada’s biosecurity planning guidance.

Feral livestock also present a specific risk. Feral livestock means any formerly domesticated livestock or progeny of domesticated livestock which have become wild and are running at large upon public or private lands in the State of Nevada and which have no physical signs of domestication. Contact between your herd and feral animals should be reported to the NDA and prevented through proper fencing and range management.

Pest Control Best Practices

Rodents, birds, and insects can carry and spread pathogens across your operation. Your biosecurity plan should include:

• Secure feed storage in rodent-proof containers to eliminate attraction points
• Regular inspection and maintenance of facility perimeters to identify entry points
• Control of standing water to reduce insect breeding habitat
• Coordination with the NDA’s Wildlife Services division for persistent wildlife intrusion problems

The NDA’s Wildlife Services program is accessible through the agency’s animal industry resources at agri.nv.gov and can provide guidance on integrated pest management strategies appropriate for your operation type and region.

Livestock guardian animals — particularly dogs — can play a role in deterring wildlife from entering your operation. Learn more about their role and limitations in our overview of facts about livestock guardian dogs.

Dead Animal Disposal Requirements in Nevada

Proper disposal of dead animals is one of the most tightly regulated aspects of livestock biosecurity in Nevada. Carcasses that are not disposed of quickly and correctly can become a disease reservoir, attract scavengers, and contaminate water sources — all of which create both public health and legal liability for your operation.

Disposal Methods and Timelines

Nevada Administrative Code NAC 571.200 establishes the approved methods and timelines for disposing of carcasses of diseased animals. A person who is required to dispose of the carcass of an animal pursuant to NRS 571.200 may comply with the requirements of that section by burying the carcass within 24 hours after death or discovery so that no part of the carcass remains within 3 feet of the surface at grade, or by causing the carcass to be consumed by fire within 24 hours after death or discovery.

The 24-hour window is strict. If you discover a dead animal — particularly one that may have died from an infectious disease — you are required to act immediately. Do not leave carcasses exposed on pasture or in pens, as this creates disease and pest risks for your entire operation.

Transport of Carcasses on Public Roads

The Department will issue permits for the conveyance of carcasses subject to NRS 571.200 on public highways and roads. Each holder of a permit shall handle and dispose of carcasses in a manner prescribed by the Division of Animal Industry of the Department and set forth in the permit. If you need to transport a carcass to a rendering facility or approved disposal site, contact the NDA Division of Animal Industry before doing so.

Diseased Animal Disposal Under Quarantine

When animals are under a hold order due to confirmed disease, the disposal process involves additional oversight. If the State Quarantine Officer deems it necessary to destroy any infected or exposed livestock in order to prevent the spread of an infectious, contagious, or parasitic disease which cannot be extirpated by means other than destroying the infected or exposed livestock, the State Quarantine Officer may have the livestock destroyed and burned, buried, or otherwise disposed of in any manner specified by the Department.

For brucellosis-positive animals specifically, an animal which reacted positively must remain on the immediate premises where it was discovered until a state or federal permit has been obtained to move the animal to a location where it can be slaughtered.

Putting It All Together: Your Nevada Biosecurity Compliance Checklist

Meeting Nevada’s livestock biosecurity requirements is an ongoing process, not a one-time task. Producers who have taken steps to prepare their operations and livestock prior to an outbreak can tip the scales in favor of surviving it in much better shape. The framework outlined in this guide — premises registration, a written biosecurity plan, animal isolation protocols, sanitation rules, wildlife management, and proper carcass disposal — represents the minimum standard of care expected of Nevada livestock producers.

As Nevada Department of Agriculture Director J.J. Goicoechea stated, “Advanced planning is the best thing you can do for yourself and your operation. During a foreign animal disease outbreak, those with enhanced plans and accurate records can and will be released for movement first.”

Start by registering your premises with the NDA if you have not already done so, then work with a veterinarian and a University of Nevada, Reno Extension specialist to develop your written biosecurity plan. For additional compliance context across related regulatory areas in Nevada, review the brand inspection requirements in Nevada and explore how other states approach disease reporting, such as livestock disease reporting in Florida and livestock disease reporting in California, for comparative insight.
