Livestock Biosecurity Requirements in Arizona Every Producer Needs to Know

Arizona’s livestock industry spans millions of acres of rangeland, feedlots, dairies, and small-scale operations — and every one of those operations is a potential entry point for infectious disease. By following good biosecurity practices, you can reduce the chances of an infectious disease being carried to your farm, your backyard, your aviary, or your pet birds by people, animals, equipment, or vehicles, either accidentally or on purpose. That protection starts with understanding exactly what the state requires of you.

Whether you raise cattle, sheep, goats, swine, horses, or poultry, Arizona has specific rules governing how you register your property, identify your animals, control movement, manage visitors, and dispose of carcasses. This guide walks you through each requirement so you can stay compliant and keep your herd healthy.

What Is Livestock Biosecurity and Why It Matters in Arizona

Biosecurity is the foundation of any healthy livestock operation. Biosecurity refers to the planning and implementation of measures that maintain healthy environments for livestock and prevent the spread of disease. In practice, it means building deliberate barriers — physical, procedural, and administrative — between your animals and the pathogens that could devastate your operation.

Arizona’s position as a southern border state makes biosecurity especially critical. Modern practices need to be adopted as the landscape of animal agriculture, interconnected markets or production systems, regional and international trade, and origins of constituent feed ingredient commodities are vastly more complicated than they were 100 years ago, not to mention Arizona’s position as a southern border state.

The Arizona Department of Agriculture (AZDA) protects the public from contagious and infectious diseases in livestock, poultry, commercially raised fish, meat, milk, and eggs — and enforces laws about moving, selling, importing, transporting, slaughtering, and stealing livestock. The AZDA’s Animal Services Division and the Office of the State Veterinarian are your primary regulatory contacts for biosecurity compliance.

Beyond regulatory compliance, a strong biosecurity program has direct financial value. Having an active biosecurity plan in place can help reduce the number of sick animals in your herd and can reduce the negative impact of an infectious disease outbreak, such as foot and mouth disease. For Arizona producers, the cost of prevention is almost always far lower than the cost of an outbreak response.

Premises Registration and Identification Requirements in Arizona

The first concrete biosecurity step the state asks of you is registering the physical location where your animals live. It starts with registering your premises where the livestock are located. This creates an official link between your animals and a specific, traceable address in the national system.

A premises is any physical location where livestock or poultry are managed, or other locations associated with animal agriculture such as feed stores, feed mills, livestock markets, or exhibitions. If a business holds livestock or poultry in more than one location, each location should have a unique PIN.

Registered premises are assigned a seven-digit, alphanumeric Premises ID number. A PIN is validated with a 911 address or GPS coordinates. GPS coordinates are necessary in the case of a pasture with no buildings or a barn with no postal address. This matters in Arizona, where large rangeland operations may have no traditional mailing address.

The PIN is a permanent number and will not change if a premises is sold. PINs are used by animal health officials for animal disease traceability and emergency response. PINs are required by producers to request movement permits during a disease outbreak or to apply for indemnity. Losing access to your PIN during a disease event could delay your ability to move animals or receive compensation.

Beyond the premises PIN, individual animal identification is required for certain species. Arizona Flock IDs are for sheep and goats only and are also referred to as Scrapie IDs. A flock ID is required for all sheep and goats to comply with state and federal identification requirements. Sheep and goats must be identified with your Arizona Flock ID number by either a tattoo or a specially-made tamper-proof ear tag applied by you.

For cattle, AZDA will continue to distribute USDA-supplied electronic ID (EID) tags for animals requiring individual identification to make the transmission of data more efficient and to ensure compliance. Most female cattle in the state have individual IDs, but it is difficult to manually capture the data currently.

Biosecurity Plan Requirements in Arizona

Arizona does not currently mandate a written biosecurity plan for all livestock producers by statute, but the AZDA and University of Arizona Cooperative Extension strongly advise every operation to have one in place. The University of Arizona Extension specifically frames this as a proactive rather than reactive approach to disease control.

A working biosecurity plan for an Arizona livestock operation should address the following core areas:

• Animal sourcing and isolation protocols — procedures for quarantining new or returning animals before they join the main herd
• Visitor and traffic management — rules for who enters the premises and what cleaning steps are required
• Equipment and vehicle sanitation — cleaning and disinfection schedules for shared or incoming equipment
• Feed and water security — storage practices that prevent contamination by rodents, wild birds, or other vectors
• Surveillance and record-keeping — routine health monitoring and documentation of animal movements
• Emergency response contacts — the AZDA State Veterinarian at (602) 542-4293 and the University of Arizona Veterinary Diagnostic Laboratory at (520) 621-2356

For poultry operations, the National Poultry Improvement Plan (NPIP) provides a structured entry point. A one-on-one biosecurity session with an AZDA agent is provided at the initial NPIP visit. NPIP is a voluntary program and Arizona does not charge a fee for participation. Enrolling gives you direct access to AZDA guidance and positions your flock for interstate movement compliance. You can learn more about livestock disease reporting in California to understand how neighboring states structure their disease response frameworks.

Animal Isolation and Movement Control Requirements in Arizona

Controlling how animals move into, within, and out of your operation is one of the most enforceable components of Arizona biosecurity law. The AZDA enforces specific import requirements that function as mandatory biosecurity checkpoints for any animal entering the state.

All livestock require an original health certificate issued by a veterinarian within 30 days prior to importation and an import permit (except horses). All photocopies of health certificates must have an original signature by the veterinarian.

The requirements vary by species. Arizona requires an ICVI (Interstate Certificate of Veterinary Inspection), an entry permit number (EPN), and a combination of TB, T. fetus, and brucellosis tests on cattle imports. The requirements vary between age groups, beef and dairy, and breeding versus slaughter or show animals. Additionally, Arizona has entry permit requirements for sheep, goats, and pigs. Horses and poultry require an ICVI, but no permit.

All horses six months of age and older require a negative test for Equine Infectious Anemia (Coggins test or CELISA) within 12 months prior to importation.

For movement within Arizona, the self-inspection program provides eligible producers with a documented pathway. If you are new to the self-inspection program, you are required to submit an application. This application must be renewed every three years pursuant to Arizona Administrative Code (R3-2-702.B.3). However, a self-inspection certificate cannot be used for changes of ownership in range cattle, removal of range cattle from the state, or cattle custom slaughter, because a livestock inspector must inspect these occurrences.

Once new animals arrive, a quarantine or isolation period before mixing them with your existing herd is a critical biosecurity step. The standard recommendation is a minimum 21- to 30-day isolation period in a separate pen or pasture with no shared water, feed, or fencing contact with resident animals. Livestock under quarantine by the Department shall not be shipped or sold by use of a self-inspection certificate. See also how livestock disease reporting in Florida handles movement controls during quarantine events for a comparative reference. For producers who transport animals regularly, understanding livestock trailer requirements in Nevada and livestock trailer requirements in Pennsylvania can also inform best practices for sanitation between loads.

Visitor, Vehicle, and Equipment Sanitation Rules in Arizona

People, vehicles, and equipment are among the most common routes of disease introduction onto a livestock premises. Arizona biosecurity guidance — reinforced by AZDA and the University of Arizona Extension — establishes clear expectations for how you manage these entry points.

AZDA encourages voluntary registration and simple biosecurity practices to protect your flock and prevent outbreaks. Key steps include isolating new birds, cleaning equipment, and keeping feed secure from rodents and wild birds. These principles apply equally to all livestock species, not just poultry.

For visitor management, your biosecurity plan should establish a defined entry point with sanitation supplies available. Best practices include:

1. Designated parking areas — keep visitor vehicles away from animal housing and feeding areas
2. Footwear sanitation — require boot washing or disposable boot covers before entering animal areas
3. Visitor logs — record the name, date, and previous farm visits of all non-resident visitors, especially veterinarians, feed representatives, and livestock buyers
4. Restricted access zones — limit entry to maternity pens, nurseries, and quarantine areas to essential personnel only
5. Clean/dirty line enforcement — establish a physical boundary between the “clean” animal zone and the “dirty” outside zone

Vehicle and equipment sanitation is particularly important when shared equipment — trailers, squeeze chutes, loading ramps — moves between multiple farms. All incoming vehicles and equipment should be cleaned of organic material and disinfected before entering your premises. By following good biosecurity practices, you can reduce the chances of an infectious disease being carried to your farm by people, animals, equipment, or vehicles, either accidentally or on purpose.

Feed storage is another critical sanitation point. Under municipal codes in Tucson and Phoenix, chicken feed must be stored in metal, rodent-proof containers. While this rule applies specifically to those municipalities, the principle of secure, pest-proof feed storage is a biosecurity best practice for all Arizona livestock operations regardless of location. Rodents and wild birds that access feed supplies can introduce pathogens directly into your animals’ food and water.

Wildlife and Pest Control Obligations in Arizona

Arizona’s diverse wildlife — including javelinas, coyotes, deer, feral pigs, and a wide variety of wild birds — creates persistent biosecurity pressure on livestock operations. Managing the interface between your animals and local wildlife is both a practical necessity and a regulatory expectation.

Wild birds are a primary concern because of their role in transmitting Highly Pathogenic Avian Influenza (HPAI). Because avian influenza has affected the poultry industry with significant losses, municipalities and owners alike emphasize humane housing and biosecurity. For poultry producers, this means housing birds in fully enclosed structures or covered runs that prevent direct contact with migratory and wild birds.

For all livestock species, wildlife and pest control obligations include:

• Fencing integrity — maintain perimeter fencing that prevents wildlife from entering feeding, watering, and housing areas
• Feed and water security — store feed in sealed, rodent-proof containers and use water systems that minimize spillage attractive to wildlife
• Carcass removal — promptly remove dead animals to avoid attracting scavengers that can spread disease (see the next section for disposal requirements)
• Rodent control programs — implement ongoing rodent monitoring and control, particularly around feed storage and animal housing
• Wild pig exclusion — feral swine are a known reservoir for multiple diseases including pseudorabies and brucellosis; report any feral swine activity near your operation to AZDA

Report unusual illness or high mortality to the AZDA State Veterinarian’s Office. If you observe unexplained deaths or neurological signs that could indicate a foreign animal disease or wildlife-borne pathogen, do not wait. In the event of an outbreak, emergency “Control Area” restrictions may limit animal movement near commercial operations.

Livestock guardian animals — including dogs — can play a role in deterring predators that might otherwise breach your perimeter and introduce disease risk. Learn more about livestock guardian dogs and their role in protecting your herd. For operations in areas with significant wildlife pressure, working with your county cooperative extension office to develop a site-specific pest management plan is strongly recommended.

Dead Animal Disposal Requirements in Arizona

Proper disposal of livestock carcasses is both a biosecurity requirement and a public health obligation in Arizona. Carcasses that are left exposed attract scavengers, contaminate soil and groundwater, and can sustain pathogens long after an animal’s death — making prompt, compliant disposal essential.

Arizona law gives the AZDA Director broad authority over carcass management during disease events. The Director of the AZDA, with the advice of the State Veterinarian, may make rules to govern the slaughter of animals and poultry affected by contagious or infectious diseases and the disposition of carcasses of animals and poultry so slaughtered when the action appears necessary to prevent the spread of contagion or infection among livestock and poultry.

Outside of declared disease events, Arizona producers are responsible for routine carcass disposal under state and county rules. The four primary approved methods are:

1. Burial — carcasses must be buried at sufficient depth (typically a minimum of three feet of cover) to prevent scavenger access, and must be located away from water sources, drainage channels, and property lines. Check with your county for specific setback requirements.
2. Incineration — burning is permitted in rural areas where local air quality regulations allow it; always verify with your county air quality district before incinerating large carcasses
3. Composting — on-farm composting of livestock carcasses is an approved method when managed correctly; the compost pile must reach sufficient internal temperatures to destroy pathogens and must be contained to prevent scavenger access
4. Rendering or licensed disposal service — contracting with a licensed rendering company or large animal removal service is the preferred option for large carcasses or during disease events

For smaller operations and backyard producers, under Arizona SCR1048, the improper disposal of biological waste — including feathers, offal, and blood — that causes odor for more than 30 consecutive minutes is a public nuisance. All remains must be bagged and disposed of per municipal solid waste rules or composted in a closed, pest-proof vessel.

Waste placement also matters at the property level. Animal wastes shall not be stored any closer than 50 feet from any property line, open space, drainage channel, or surface waters. While this specific code applies to Taylor, Arizona, similar setback principles appear across Arizona county codes and represent the general standard you should apply.

During a confirmed disease event, the goal is to be able to trace back to origin any disease within 48 hours of its recognition. Your cooperation with AZDA inspectors regarding carcass preservation and documentation is legally required during those investigations. Producers who have already registered their premises and maintained accurate animal records will be in the strongest position to respond quickly and limit their exposure to further losses.

For a broader picture of how disease reporting and disposal obligations work across the region, review livestock disease reporting in Florida and livestock disease reporting in California — two states with similarly complex livestock regulatory environments. Arizona producers operating near state lines may also want to familiarize themselves with Nevada’s livestock trailer requirements and Wisconsin’s livestock trailer rules if you ship animals interstate.

Staying current with AZDA guidance, maintaining your premises registration, and building a written biosecurity plan are the three most impactful steps you can take right now to protect your operation, your neighbors’ operations, and Arizona’s agricultural economy as a whole.
