Livestock Biosecurity Requirements in Louisiana Every Producer Should Know

Louisiana’s warm, humid climate and sprawling agricultural landscape make it one of the most productive livestock states in the South — and one of the most vulnerable to rapid disease spread. A single biosecurity lapse can move a pathogen through an entire parish before state officials even receive a report.

Whether you raise cattle, swine, poultry, sheep, or goats, understanding Louisiana’s livestock biosecurity requirements is not optional — it is the foundation of a compliant, financially protected operation. This guide walks you through every major requirement, from premises registration to dead animal disposal, so you know exactly what the Louisiana Department of Agriculture and Forestry (LDAF) expects from you.

What Is Livestock Biosecurity and Why It Matters in Louisiana

Biosecurity refers to everything people do to keep diseases — and the viruses, bacteria, fungi, parasites, and other microorganisms that cause diseases — away from birds, livestock such as cattle, swine, sheep, and goats, property, and people. In practice, it is the sum of every policy, habit, and physical barrier you put between your herd and the outside world.

Anyone involved with poultry or livestock production, from a small backyard operation to a large commercial producer, should review their biosecurity activities to ensure the health of their animals. Louisiana’s subtropical conditions — high humidity, standing water after storms, and year-round insect pressure — accelerate the transmission of pathogens that drier states manage more easily.

In general, there are four major categories of diseases that can affect livestock. Some are considered high-consequence, meaning they spread rapidly from animal to animal and herd to herd, and are expensive and difficult to eradicate. Outbreaks of foot-and-mouth disease, Highly Pathogenic Avian Influenza (HPAI), and brucellosis have all demonstrated how quickly a single infected animal can trigger state-wide quarantines and market shutdowns.

The Louisiana Board of Animal Health — governed under Louisiana Administrative Code 7:XXI — is the regulatory body responsible for preventing, controlling, and eradicating diseases in livestock and poultry statewide. It is also responsible for licensing and supervision of livestock dealers and the chartering and supervision of auction markets in Louisiana. Compliance with its rules protects not just your animals, but the broader agricultural economy of the state.

Premises Registration and Identification Requirements in Louisiana

Before you can legally move animals or participate in state disease-response programs, you need a Premises Identification Number (PIN). A Premises ID (PIN) is a federal program that assigns a unique number to a specific geographic location where livestock animals are located. Premises ID numbers are used by animal health officials to help identify the location of an animal in the event of a disease outbreak or animal emergency.

To be registered, you fill out the application form and email questions to vetreports@ldaf.state.la.us. Registration is free, and your PIN stays with the physical location — not with the animals themselves. If you sell your property, the new owner will need their own registration.

Beyond premises registration, Louisiana requires individual animal identification for specific species and movement scenarios. Any person who keeps, breeds, raises, contains, harvests, kills, slaughters, buys, sells, trades, or transfers ownership of any type of farm-raised alternative livestock in Louisiana must obtain a farm-raising license from the department prior to engaging in such activities. Species considered alternative livestock under this license include any imported or domestically raised exotic deer, antelope, elk, or farm-raised whitetail deer.

For cattle moving to exhibitions and shows, individual identification is mandatory. All cattle consigned to fairgrounds, livestock show grounds, sale grounds, and rodeos must meet the general requirements of the applicable regulation. Official identification must appear on a Certificate of Veterinary Inspection (CVI) that accompanies every animal. The LDAF strictly monitors biosecurity; if you import chicks from out-of-state, you must have a Certificate of Veterinary Inspection (CVI).

Poultry producers have an additional registration pathway through the National Poultry Improvement Plan (NPIP). The LDAF uses the NPIP program to protect Louisiana’s poultry sector. Through the program, LDAF works with NPIP participants to test poultry for Salmonella pullorum, avian influenza, Mycoplasma gallisepticum, and Mycoplasma synoviae using tests and methods that meet or exceed NPIP program standards. NPIP certification also opens interstate commerce channels that are closed to non-certified flocks.

Biosecurity Plan Requirements in Louisiana

Louisiana does not mandate a single universal biosecurity plan template for all livestock operations, but LDAF strongly directs producers to develop and maintain a written plan. You should develop a biosecurity plan to protect your herd. For commercial dairy and poultry operations, a documented plan is effectively a regulatory expectation, particularly in the context of HPAI preparedness.

Biosecurity plans control the introduction and spread of disease by evaluating and addressing the primary routes of disease transmission. An effective biosecurity plan will control several diseases at one time. This means a single well-designed plan can simultaneously address brucellosis, trichomoniasis, HPAI, and other pathogens without requiring separate protocols for each.

Your biosecurity plan should address the following core components:

• Disease transmission routes — Aerosol transmission via droplets that pass through the air; direct contact through open wounds, mucous membranes, blood, or saliva; reproductive transmission; fomite transmission through contaminated objects such as brushes, needles, shovels, trailers, and humans; and oral transmission through contaminated feed or water.
• Herd health baseline — Check the health status of your cattle herd to determine whether diseases are present on the farm. Start with a healthy herd because an unhealthy herd increases the risk of infection.
• Emergency contact protocols — Your plan should name your accredited veterinarian and include LDAF’s disease-reporting line at 225-925-3980.
• Record-keeping system — Document all animal movements, visitor logs, cleaning events, and testing results.

Biosecurity is not a one-time single-step process. It is a dynamic activity that requires continuous evaluation and improvement along the way. Effective biosecurity practices might seem like a lot of work and investment, but it is a cost-effective way to secure strong and steady returns from your beef production operation.

LDAF encourages producers to use USDA APHIS resources as a supplement to their plans. USDA’s Animal and Plant Health Inspection Services (APHIS) has materials about biosecurity, including videos, checklists, and toolkits available online. You can also find HPAI-specific biosecurity checklists and toolkits directly on the APHIS website.

Animal Isolation and Movement Control Requirements in Louisiana

Controlling how animals enter and move through your operation is one of the most powerful biosecurity tools available to you. Keeping infected animals and contaminated material away from uninfected animals is the most important and effective part of biosecurity.

Quarantine of new arrivals is a firm LDAF recommendation. In addition to adhering to strict biosecurity practices in operations, LDAF recommends quarantining new animals for 30 days before introducing them into a herd. This 30-day window allows subclinical infections to become visible before a new animal mixes with your resident herd.

For bulls specifically, Louisiana law goes further than a recommendation. In Louisiana, Trichomoniasis is a reportable cattle disease. This means that this disease is regulated by LDAF, and within 30 days of purchase, all bulls must be tested and placed in an approved holding pen that has been inspected by LDAF personnel. If testing is not performed, the bull must be resold to slaughter at a USDA-approved livestock market.

For animals attending exhibitions, the movement control rules are detailed and species-specific:

No cattle from brucellosis quarantined herds or brucellosis quarantined areas are allowed to be exhibited in the state of Louisiana or consigned to breeders’ association sales in Louisiana.

For interstate movement of dairy cattle, LDAF has implemented heightened CVI validity rules. In an effort to protect the dairy herds and poultry flocks in Louisiana, a Certificate of Veterinary Inspection (CVI) being used to ship dairy cattle from any state that has, or has had, a detection of HPAI virus in dairy cattle in the past 30 days will be valid for not more than 7 days.

If you also transport your animals across state lines, be sure to review trailer-specific compliance requirements, such as those covered for neighboring states like Nevada and Wisconsin, which illustrate how transport standards vary by jurisdiction.

Visitor, Vehicle, and Equipment Sanitation Rules in Louisiana

Every person, vehicle, or piece of equipment that crosses onto your property is a potential disease vector. Louisiana’s biosecurity framework, aligned with LDAF and USDA APHIS guidance, places the responsibility for managing that risk squarely on the producer.

Biosecurity measures can include keeping visitors to a minimum, changing clothes before entering areas, and cleaning tools or equipment before moving them to a new facility. These are not suggestions — in a disease investigation, failure to maintain visitor and equipment logs can expose you to liability and complicate quarantine proceedings.

The following sanitation standards apply to all livestock premises in Louisiana:

• Visitor access control: Restrict access to your premises to employees and service personnel, since pathogens can be introduced by vehicles, clothing, and equipment.
• Clean/dirty zone separation: Establish a clean/dirty line, where only certain people, vehicles, and equipment are allowed on the clean side.
• Waiting periods between farm visits: Require a waiting period of 24 to 48 hours between livestock premises visits for your employees and also your veterinarian.
• Designated vehicle parking: Designated parking is required for both small and large farms to prevent the transmission of diseases onto a farm. Possibly contaminated vehicles such as carcass disposal trucks and feed trucks should have separate entrances and parking areas to avoid cross-contamination between vehicles.
• Equipment decontamination: Do not cross-use shovels, feed buckets, brushes, or other equipment between isolated animals and other livestock.
• Personal protective equipment (PPE): Use disposable plastic boots if the visit requires entering animal facilities. If animal contact is possible, coveralls should be worn.

Signage is an underutilized but important compliance tool. Post signs within and outside the farm that are legible, clearly written, visible, sturdy, and hung or pasted. Signs provide information on how people should act within and outside the farm. Within the farm, signs direct and guide employees. Outside the farm, they help guide visitors and prevent accidental entry.

For transport vehicles specifically, cleaning and disinfection protocols should be documented. Use your own trailer to transport your animals. If you do not have your own transportation, it is crucial to disinfect all returning animals’ hooves prior to entering your barn or stable. Producers in neighboring states such as Pennsylvania face similar transport sanitation expectations, underscoring that this is a national standard, not unique to Louisiana.

Wildlife and Pest Control Obligations in Louisiana

Louisiana’s diverse ecosystem — including migratory bird flyways, feral hog populations, and abundant waterfowl — creates ongoing wildlife-related biosecurity pressure that producers in drier states rarely face.

To the extent possible, prevent contact between your animals and poultry, pets, wildlife (particularly ruminants and waterfowl), and rodents. This is especially critical in Louisiana, where migratory waterfowl are a known reservoir for avian influenza viruses that can cross into livestock populations.

LDAF provides a specific legal mechanism for managing black vultures, which are federally protected but can pose serious risks to newborn livestock. The Migratory Bird Depredation Permit is a federal permit, and all Louisiana landowners, farmers, ranchers, and livestock producers applying for and receiving approval of a LDAF-AHFS Black Vulture Depredation Sub-Permit will be required to follow all USFWS Migratory Bird Depredation Permit authorizations and conditions. Failure to do so could result in federal citations and fines.

Feral hogs are another major wildlife biosecurity concern in Louisiana. People get trichinellosis after eating raw or undercooked meat, such as feral (wild) swine. Feral hogs can also transmit brucellosis and pseudorabies to domestic pig herds through fence-line contact or shared water sources.

Practical wildlife and pest control obligations for Louisiana livestock producers include:

1. Secure feed storage — Store all feed in rodent-proof containers and bins. Rodents contaminate feed with urine and feces carrying leptospirosis and salmonella.
2. Perimeter fencing maintenance — Inspect all perimeter fencing regularly and repair damaged areas to ensure your livestock stays in and straying livestock and wild animals stay out.
3. Water source protection — Cover or fence stock ponds and troughs to limit waterfowl access, which is a primary HPAI transmission pathway.
4. Feral hog exclusion — Use hog-proof fencing (minimum 4-foot woven wire with a hot wire at the base) around swine operations and pastures where pigs graze.
5. Rodent control programs — Implement routine bait station programs around feed storage areas, poultry houses, and livestock barns.

Producers interested in managing wildlife interactions alongside hunting activities on their land should also review Louisiana hunting license requirements to ensure any depredation or wildlife management activities remain legally compliant. You may also find it useful to learn about livestock guardian dogs, which can serve as a non-lethal deterrent against predatory wildlife near your herd.

Dead Animal Disposal Requirements in Louisiana

Improper carcass disposal is one of the fastest ways to spread disease from a dead animal to a living herd. Louisiana law places the responsibility for compliant disposal directly on the producer.

The owners, agents, firms, or corporations, or persons in charge of any or all livestock on ranges, pastures, or other premises shall be responsible for disposition of all carcasses in those herds over which they have jurisdiction, with reference to complying with the provisions of this Part. This language from Louisiana Revised Statutes § 3:2131 makes clear that there is no ambiguity about who bears the legal obligation.

Louisiana law recognizes several approved disposal methods for livestock carcasses. The primary options available to producers on rural or agricultural land are:

• Burial — Carcasses must be buried deep enough to prevent access by scavengers and to avoid contaminating groundwater. Check with your parish for any local setback requirements from property lines, water bodies, and wells before digging.
• Incineration — On-farm incineration using an approved unit is permitted. The provisions of the disposal statute shall not apply to animal carcasses within the limits of a city or town which is provided with an incinerator or in which a rendering plant is operated, provided such incinerator or rendering plant is equipped with facilities to properly transport or handle carcasses in a manner to prevent dissemination of infection.
• Rendering — Contracting with a licensed rendering facility is an approved and biosecure method of disposal. Rendered carcasses are processed in a way that destroys pathogens.
• Composting — On-farm composting is permitted under LDAF guidelines when done correctly, with proper carbon-to-nitrogen ratios, temperature monitoring, and containment to prevent leachate runoff.

Timing matters as much as method. In Louisiana’s heat and humidity, carcasses decompose rapidly and attract scavengers within hours. You should plan to dispose of dead animals within 24 hours of discovery to minimize disease transmission risk and to comply with the spirit of the state’s nuisance and sanitation statutes.

Producers raising cervidae or alternative livestock species face additional oversight. The Office of the State Veterinarian has established a surveillance zone for herds near affected deer farms and is diligently reviewing recent movement records. All deer farms in the surveillance zone are under restricted movement until further notice. If you operate a deer farm and an animal dies, notify LDAF before disposal to confirm whether CWD surveillance sampling is required.

For a broader view of how livestock disease reporting and disposal obligations are structured in comparable states, see how requirements are handled in Florida, California, Colorado, and Illinois — all of which share similar frameworks rooted in USDA APHIS standards.

Meeting Louisiana’s livestock biosecurity requirements is not a one-time checklist exercise. It is an ongoing commitment that protects your investment, your neighbors’ herds, and the state’s agricultural economy. Start with your Premises ID registration, build a written biosecurity plan with your accredited veterinarian, and review each of the areas covered in this guide at least annually — or any time disease pressure increases in your region.
