Livestock Disease Reporting in Louisiana: What Every Producer Needs to Know
August 23, 2026
If you raise cattle, poultry, swine, horses, or any other livestock in Louisiana, you carry a legal and civic responsibility that goes beyond feeding and housing your animals. When a serious disease appears — or even when you only suspect one — state and federal law may require you to act quickly, notify the right authorities, and cooperate with an investigation.
Understanding Louisiana’s livestock disease reporting system is not just about staying out of legal trouble. Reporting helps identify disease outbreaks, limits their spread, and minimizes the economic and health impacts on animals and people. This guide walks you through every stage of the process, from knowing which diseases trigger a report to understanding what happens after you make that call.
Reportable Livestock Diseases in Louisiana
A reportable animal disease is one that, by law, must be reported to state and/or federal animal or public health officials. “Reportable” means that the USDA Animal and Plant Health Inspection Service (USDA APHIS) has a control or eradication program in place for the disease. Louisiana follows both the national framework and its own state-specific list administered by the Louisiana Department of Agriculture and Forestry (LDAF).
These diseases are high risk with severe economic, animal health, and often public health consequences. Examples of reportable diseases include brucellosis, scrapie, bovine tuberculosis, pseudorabies, New World screwworm, and vesicular stomatitis. Louisiana producers should be familiar with each of these, as they are among the most commonly flagged conditions in the region.
Among reportable diseases are foreign animal diseases (FAD), also called transboundary animal diseases. These are high-risk animal diseases that are not normally present in the United States or have been previously eradicated. If you suspect a foreign animal disease, that report becomes even more urgent.
Beyond the national list, Louisiana has state-specific reportable diseases. In Louisiana, Trichomoniasis is a reportable cattle disease. Trichomoniasis is a bovine venereal disease that can cause substantial reproductive and economic loss in cow-calf operations that use natural service. Many states, including Louisiana, now have regulations on movement of bulls to prevent its spread.
Poultry producers face additional reporting obligations. Through the National Poultry Improvement Plan (NPIP), LDAF works with 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. Avian influenza — particularly the highly pathogenic strain — remains one of the most closely monitored diseases in the state. You can learn more about Newcastle disease and related poultry conditions that may overlap with reportable disease symptoms.
For cattle operations, bovine diseases covered under both state and federal frameworks can carry serious movement and trade consequences, making familiarity with the full reportable list essential for any beef or dairy producer.
| Disease | Species Affected | Reporting Authority |
|---|---|---|
| Brucellosis | Cattle, swine, goats | LDAF / USDA APHIS |
| Bovine Tuberculosis | Cattle, bison | LDAF / USDA APHIS |
| Scrapie | Sheep, goats | LDAF / USDA APHIS |
| Pseudorabies | Swine | LDAF / USDA APHIS |
| Highly Pathogenic Avian Influenza (HPAI) | Poultry, birds | LDAF / USDA APHIS |
| Vesicular Stomatitis | Cattle, horses, swine | LDAF / USDA APHIS |
| New World Screwworm | All livestock | LDAF / USDA APHIS |
| Trichomoniasis | Cattle (bulls) | LDAF |
| Equine Infectious Anemia (EIA) | Horses | LDAF |
| Chronic Wasting Disease (CWD) | Deer, elk | LDAF / LDWF |
Who Is Required to Report a Livestock Disease in Louisiana
Louisiana’s reporting requirements apply to a broader group of people than many producers realize. The obligation does not rest solely on veterinarians — it extends to anyone involved in the care, management, or observation of livestock.
Veterinarians are required to report diseases of both agricultural and public health importance. The Office of Public Health requests that conditions on both the agriculturally important diseases list and the State Sanitary Code be reported to the Public Health State Veterinarian and the Louisiana Department of Agriculture and Forestry.
Livestock owners who suspect the occurrence of a contagious disease should immediately contact the local practicing veterinarian, area regulatory veterinarian, or county agent who, in turn, will be responsible for reporting to the state veterinarian. This means that as a producer, your first step is contacting a professional — but you are not off the hook simply because you passed the information along.
The following parties carry reporting responsibility in Louisiana:
- Licensed veterinarians (private practice and regulatory)
- Livestock owners and producers
- County agents and agricultural extension personnel
- Livestock auction market operators and their employed veterinarians
- Diagnostic laboratory personnel
- Feed program operators who observe signs of contamination-related illness
The Louisiana Board of Animal Health is responsible for the prevention, control, and eradication of diseases in livestock and poultry, as well as the licensing and supervision of livestock dealers and the chartering and supervision of auction markets. Auction market operators carry a specific duty: they must observe all livestock being offered for sale and detect any showing or visible symptoms of disease so that these animals may be observed by a veterinarian and could be rejected and returned to the owner’s premises.
Signs and Symptoms That Trigger a Report in Louisiana
Knowing when to act is as important as knowing who to call. Several disease conditions have recognizable symptom profiles that should put you on alert. You do not need a confirmed diagnosis to initiate a report — suspicion alone is enough to trigger the obligation under Louisiana regulations.
General warning signs across all livestock species:
- Sudden or unexplained death in multiple animals
- Rapid spread of illness through a herd or flock
- Unusual neurological signs (circling, tremors, loss of coordination)
- Blistering or ulcerative lesions on the mouth, feet, or teats
- Severe respiratory distress or nasal discharge
- Unexplained abortions or reproductive failure
- Dramatic drop in milk production
- Extreme weight loss or wasting
For poultry specifically, if domestic poultry or other farm birds exhibit signs of avian influenza, bird owners should consult their local veterinary professional and notify state or federal animal health officials. Birds infected with the HPAI virus may show one or more of the following signs. These include sudden death without prior symptoms, lack of energy, decreased egg production, swelling of the head and wattles, and discoloration of the comb and legs.
For deer and cervid operations, signs of Chronic Wasting Disease include weight loss, uncoordinated movement, listlessness, excessive thirst or urination, drooling, drooping ears, and behavioral changes.
For cattle showing unusual wound activity, anyone who suspects suspicious wounds, maggots, or infestations should notify a veterinarian immediately — this may indicate New World Screwworm, a federally regulated foreign animal disease.
Many serious livestock conditions share symptoms with common zoonotic diseases. Understanding how zoonotic diseases spread between animals and people can help you assess the urgency of a situation and protect both your herd and your family.
How to Report a Livestock Disease in Louisiana
When you observe signs that warrant a report, Louisiana provides several clear pathways to notify the appropriate authorities. The channel you use may depend on the type of disease, the species involved, and whether the situation is an emergency.
Step 1: Contact your local veterinarian or county agent first. Livestock owners who suspect the occurrence of contagious disease should immediately contact the local practicing veterinarian, area regulatory veterinarian, or county agent who, in turn, will be responsible for reporting to the state veterinarian.
Step 2: Report directly to LDAF if necessary. Producers should report any possible symptoms to the Louisiana Department of Agriculture and Forestry at 225-925-3980. This line connects you to the LDAF Office of Animal Health and Food Safety (AHFS).
Step 3: Use disease-specific reporting channels when applicable.
- Sick or dead farm birds can be reported to USDA toll-free at 1-866-536-7593, or in Louisiana, contact the LDAF Diagnostic Lab at (318) 927-3441.
- To report diseases and deaths that may be related to adulterated or contaminated animal food, contact the LDAF Feed Program at (225) 935-2176 or Feedprogram@ldaf.state.la.us, or for animal food-related emergency incidents contact the LDAF Emergency Hotline at 1-(855)-452-5323.
- For veterinary health matters and permit requests, contact the LDAF Office of the State Veterinarian at vetreports@ldaf.state.la.us or call (225) 925-3980.
Step 4: Register your Premise ID if you have not already done so. A Premise ID (PIN) is a federal program that assigns a unique number to a specific geographic location where livestock animals are located. Premise 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. Having a registered PIN allows officials to respond to your location faster and trace animal movements more efficiently.
Producers in neighboring states follow similar frameworks. If you also manage operations across state lines, reviewing livestock disease reporting in Florida or livestock disease reporting in Texas can help you stay compliant wherever your animals travel.
Reporting Deadlines and Timeframes in Louisiana
Louisiana does not use a single uniform deadline for all reportable diseases. Timeframes vary based on the disease category, the species involved, and the urgency of the public or animal health risk. Understanding these differences helps you act within the required window.
| Scenario | Required Timeframe | Authority |
|---|---|---|
| Suspected foreign animal disease (FAD) | Immediately / same day | LDAF / USDA APHIS |
| HPAI in poultry or livestock | Immediately upon suspicion | LDAF Diagnostic Lab |
| Trichomoniasis in bulls (post-purchase testing) | Within 30 days of purchase | LDAF |
| NPIP poultry/hatching egg shipment records (VS 9-3) | Within 7 days of shipment or movement | USDA APHIS / LDAF |
| General contagious disease suspicion | Immediately — contact vet or county agent | LDAF State Veterinarian |
For trichomoniasis specifically, in Louisiana, Trichomoniasis is a reportable cattle disease, 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 poultry record-keeping, producers should keep records of poultry purchases using VS 9-3 forms (Report of Sales of Hatching Eggs, Chicks and Poults) and submit electronic VS 9-3 forms to MBAH within seven days of poultry or hatching egg shipment or movement.
For high-consequence diseases like HPAI, the expectation is immediate action. For after-hours and weekends, call the FAD Hotline at 866-536-7593. This 24-hour line exists precisely because foreign animal diseases cannot wait until Monday morning.
Producers in other states operate under similar urgency requirements. See how livestock disease reporting in Michigan and livestock disease reporting in Illinois handle comparable deadlines for context.
What Happens After You Report in Louisiana
Once a report is made, Louisiana’s regulatory system moves through a structured response process. You should expect official contact, possible on-site investigation, and — depending on the disease — potential movement restrictions on your animals and property.
Investigation: An investigation of the reported contagious disease will be made by representatives of the Livestock Sanitary Board, preferably with the veterinarian or county agent reporting the disease. This cooperative approach means the person who initially identified the problem is usually part of the on-site evaluation team.
Disease outbreak coordination: Reports of disease outbreaks will be coordinated by the state veterinarian. The state veterinarian serves as the central authority for managing the response, communicating with federal agencies, and directing field personnel.
Quarantine: If necessary to protect the animal and poultry populations, a quarantine may be imposed on involved and exposed animals and areas. The quarantine will remain in effect until the threat has been removed. A quarantine can restrict the movement of animals on and off your property and may affect neighboring operations if exposure is suspected.
In addition to protecting the livestock industry from theft and animal diseases through prevention, diagnosis, eradication, and other measures, AHFS also coordinates emergency response for LDAF. This means that in serious situations, the response may involve not just animal health personnel but also broader emergency management coordination.
For auction markets where disease is detected, after the occurrence of an infectious or contagious disease in a livestock auction market, it must be cleaned and disinfected in an approved manner with a disinfectant before livestock will be permitted to enter the establishment for any purpose.
If the disease has public health implications, the response involves multiple agencies. Veterinarians are required to report diseases of both agricultural and public health importance. The Office of Public Health requests that conditions on both the agriculturally important diseases list and the State Sanitary Code be reported to the Public Health State Veterinarian and the Louisiana Department of Agriculture and Forestry.
Understanding how livestock disease reporting in Colorado and livestock disease reporting in California handle post-report procedures can give you a broader picture of how state systems typically respond to confirmed disease events.
Penalties for Failing to Report in Louisiana
Louisiana takes non-compliance with livestock disease reporting requirements seriously. Failing to report a suspected or confirmed reportable disease can expose you to regulatory, civil, and criminal consequences — and can significantly worsen the outcome of a disease event for your operation and your neighbors.
Regulatory consequences: The Louisiana Board of Animal Health has broad authority to enforce animal health regulations. Any person operating a livestock auction market without a valid livestock auction permit will be in violation of this regulation and subject to prosecution. This principle extends to disease reporting failures — operating outside the regulatory framework invites enforcement action.
For trichomoniasis quarantine facilities specifically, a trichomoniasis quarantine facility permit may be canceled upon written notice that the operation does not meet the requirements of this Section, or when the owner or operator of such facility has been found to be in violation of a rule or has been found to be in violation of any provision of Chapter 16 of Title 3 of the Louisiana Revised Statutes.
Federal consequences: Because many reportable diseases fall under federal jurisdiction through USDA APHIS, failure to report can also trigger federal enforcement. 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 permit will be required to follow all USFWS authorizations and conditions. Failure to do so could result in Federal citations and fines. Similar federal authority applies to USDA-regulated livestock disease reporting.
Economic consequences: Beyond legal penalties, failure to report promptly can dramatically increase the economic damage to your own operation. A disease that spreads unchecked through a herd or region results in larger quarantine zones, more animals under movement restrictions, and potentially higher depopulation costs. Some diseases are considered high-consequence, meaning they spread rapidly from animal to animal and herd to herd, and are expensive and difficult to eradicate. The response to high-consequence diseases involves various state and federal agencies in efforts to control further spread.
- Permit cancellation or suspension for auction markets and dealers
- Civil fines under Louisiana Revised Statutes Title 3
- Criminal prosecution for willful violations
- Loss of eligibility for state and federal indemnity programs
- Expanded quarantine zones affecting neighboring operations
- Mandatory depopulation without compensation in cases of deliberate concealment
The Louisiana Board of Animal Health governs compliance across the livestock industry. The Board is responsible for the prevention, control, and eradication of diseases in livestock and poultry, as well as the licensing and supervision of livestock dealers and the chartering and supervision of auction markets. The Board also ensures that all auction market services are in compliance with all laws and regulations pertaining to animal health.
If you manage multiple species or multi-state operations, staying current on reporting obligations in every state where your animals are located is essential. Review how Florida handles livestock disease reporting to understand the variation in penalty structures across state lines. For species-specific health guidance beyond livestock, resources on common diseases in pet birds and pigeon diseases can help poultry producers recognize overlapping conditions in mixed-bird environments.
Louisiana’s livestock disease reporting system exists to protect producers, animals, and the public. Knowing your obligations — and meeting them promptly — is one of the most effective biosecurity measures available to any operation, regardless of size.
