Livestock Biosecurity Requirements in New York: What Every Producer Needs to Know

New York is one of the most agriculturally diverse states in the Northeast, and keeping its livestock operations healthy depends on every producer following sound biosecurity practices. Whether you raise dairy cattle, sheep, swine, or poultry, the rules governing how you protect your herd or flock from disease are not optional — they carry real legal weight and real consequences when ignored.

This guide walks you through the core livestock biosecurity requirements in New York, covering everything from premises registration and animal identification to dead animal disposal. Understanding these obligations helps you stay compliant, protect your investment, and contribute to the statewide disease prevention network that benefits every producer in the state.

What Is Livestock Biosecurity and Why It Matters in New York

Biosecurity refers to practices designed to prevent the introduction and spread of diseases on farms. It is crucial for livestock operations because it protects animals from pathogens, ensuring farm survival and profitability. In practical terms, biosecurity is the set of daily habits, structural controls, and documented protocols that stand between your herd and a potentially devastating outbreak.

The New York State Department of Agriculture and Markets’ Division of Animal Industry is responsible for ensuring animal and public health through control and eradication of infectious and contagious diseases in New York State livestock and poultry and implementation of pre-harvest food safety measures at the farm level. That mandate translates directly into enforceable requirements for producers across the state.

The stakes are significant. New York State has taken multiple preventative measures to protect animal and public health since the first detection of Highly Pathogenic Avian Influenza (HPAI) in dairy cattle in Texas in March 2024, including orders on import requirements for dairy cattle and testing requirements for lactating dairy cattle entering fairs or exhibitions. Biosecurity failures in one operation can trigger movement restrictions, testing mandates, and economic losses that ripple across an entire region.

Outbreaks of animal disease trigger heightened regulatory oversight, movement restrictions, and mandatory reporting. Producers should maintain readiness for rapid response, including quarantine, testing, and coordination with state and local authorities. Proactive biosecurity is always less costly than reactive containment.

Premises Registration and Identification Requirements in New York

Before you can move animals, apply for indemnity, or obtain official identification tags, your operation must be registered. A premises identification number (PIN) or location identifier (LID) is a unique code permanently assigned to a physical location and is required to purchase official animal identification tags. Each state administers PIN or LID registration.

A premises is any physical location where livestock and poultry animals are managed and includes all locations where livestock are born, raised, marketed, or exhibited. A PIN or location identifier is a unique number permanently assigned to a single physical location. This includes feed stores, feed mills, livestock markets, or exhibitions. If your business holds livestock in more than one location, each location should have a unique PIN.

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. You can register through the New York State Department of Agriculture and Markets by phone or online application. 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.

Beyond premises registration, animal identification is a core legal requirement for many species. Agriculture and Markets’ Part 61 and Article 5, Section 90 C requires all parties dealing in livestock, including horses, to obtain a Domestic Animal Health Permit (DAHP). Any person who buys or sells livestock — cattle, swine, horses, deer, camelids, sheep, goats, or poultry — as a business practice, not as part of a breeding, feeding, or dairy operation, needs a domestic animal health permit.

Cattle identification rules have also been updated at the federal level. USDA’s final rule for cattle ID requires all official tags applied to cattle after November 5, 2024 to be both RFID and visually readable. New York producers must comply with this federal standard when tagging cattle for interstate movement or sale. You can learn more about how identification requirements intersect with movement rules by reviewing livestock disease reporting requirements in Florida and livestock disease reporting requirements in California as comparative references for how neighboring states structure their programs.

Biosecurity Plan Requirements in New York

New York does not currently mandate a single universal written biosecurity plan for all livestock producers, but regulatory expectations — especially under disease response orders — effectively require that you have documented procedures in place. The Department encourages all producers to review their biosecurity plans and take precautions to protect their animals.

A functional biosecurity plan should address your operation’s specific risks and document how you manage them. At a minimum, a biosecurity plan should be reviewed and updated annually. Key components to include are:

• A labeled map of your premises showing access points and animal housing areas
• Identification of your Line of Separation (the boundary between clean and potentially contaminated zones)
• Protocols for animal movement onto and off the property
• Visitor, vehicle, and equipment entry procedures
• Cleaning and disinfection schedules
• Isolation and quarantine procedures for new or sick animals
• Emergency contact list including your veterinarian and NYSDAM’s Division of Animal Industry

The New York State Sheep/Goat Health Assurance Program is a disease prevention program developing farm-specific herd and flock health plans. If you raise sheep or goats, enrolling in this program gives you a structured framework for building and maintaining your biosecurity plan with state guidance. Producers should work with licensed veterinarians to establish herd health plans, disease prevention strategies, and response protocols for outbreaks.

Records of vaccinations, deworming, medical treatments, and emergency care should be maintained. These records are not just good practice — they are the documentation you will need if a disease event triggers an investigation or indemnity claim. For context on how disease reporting ties into biosecurity obligations, see livestock disease reporting requirements in Colorado.

Animal Isolation and Movement Control Requirements in New York

Controlling how and when animals move onto, off of, and within your premises is one of the most effective disease prevention tools available. The Department oversees the proper requirements for livestock, poultry, and companion animals being imported or exported from the state. Requirements vary for the type of animal; however, owners generally need to supply a Certificate of Veterinary Inspection and proof of identification.

When importing poultry into New York for any purpose other than slaughter, a Certificate of Veterinary Inspection issued within 30 days prior to entry or a USDA VS Form 9-3 is required. Additionally, poultry must be from an NPIP US Pullorum-Typhoid Clean flock or be tested for pullorum-typhoid within 90 days prior to entry. Poultry must also be from an NPIP US H5/H7 Avian Influenza Clean Flock or from a flock in which 30 birds were tested for avian influenza within 10 days prior to entry.

For new animals arriving at your operation regardless of species, isolation is essential before commingling with your existing herd or flock. Isolate any purchased cattle from the rest of your herd for at least four weeks. After four weeks, check the health status of all purchased cattle. During isolation, monitor animals daily for signs of illness and consult your veterinarian before introducing them to the general population.

Movement restrictions become mandatory during a declared disease event. Outbreaks of animal disease trigger heightened regulatory oversight, movement restrictions, and mandatory reporting. Your premises PIN is what allows animal health officials to locate your operation and issue or clear movement permits quickly during an emergency. Having your PIN registered before a crisis is not optional — it is the foundation of your ability to legally move animals during a control area situation.

For fair and exhibition movement, New York imposes species-specific testing requirements. In June 2024, the state announced new testing requirements for lactating dairy cattle entering fairs or exhibitions — they must be tested and show negative results for HPAI within seven days prior to entering a fair, including The Great New York State Fair, county fairs, or other exhibitions. The test must be conducted by an approved National Animal Health Laboratory Network (NAHLN) lab.

If you transport livestock across state lines, trailer compliance is also part of your biosecurity and legal obligations. Review livestock trailer requirements in Pennsylvania and livestock trailer requirements in Nevada to understand how neighboring and comparison states regulate transport vehicles.

Visitor, Vehicle, and Equipment Sanitation Rules in New York

People, vehicles, and equipment are among the most common pathways for disease introduction onto a farm. It is important to be aware that people can play a role in the spread of disease by carrying the virus on their hands, shoes, and clothing. This is why New York’s regulatory guidance — and the biosecurity best practices endorsed by NYSDAM — place significant emphasis on controlling who and what enters your operation.

For poultry operations specifically, NYSDAM has published official guidance that includes the following visitor protocols:

• Require all visitors to use covers on their footwear and to disinfect all footwear.
• Ask all visitors if they have had any contact with any kind of bird in the past five days.
• Forbid entry to employees and visitors who own any kind of fowl. Discourage unnecessary visitors and use biosecurity signs to warn people not to enter buildings without permission.

These protocols apply broadly to livestock operations as well. Control access to your farm by limiting entry points — one entry point is preferable — and locking restricted areas. Restrict unauthorized vehicle entry into farm facilities. Have visitors report to management and sign a visitor register or logbook on arrival.

Vehicle and equipment sanitation is equally critical. Clean and disinfect the wheels of farm vehicles both before and after use. For incoming deliveries, require feed delivery trucks to use separate road access to your designated loading and unloading area that is away from other livestock when possible. Make sure feed delivery truck tires are cleaned and disinfected before entering the farm. Make sure truck drivers wear disposable boot covers or provide them with some.

Cleaning and disinfection — also referred to as C&D — is a key part of biosecurity. C&D reduces or kills germs that can persist on surfaces for days or weeks. Always remove visible organic matter such as manure and bedding before applying disinfectants, as organic material significantly reduces the effectiveness of most chemical agents. Keep a log of all C&D activities as part of your biosecurity documentation. You can also review how brand inspection requirements in Washington integrate with movement and sanitation protocols for additional context.

Wildlife and Pest Control Obligations in New York

Wild animals and farm pests are significant disease vectors, and New York law provides specific guidance on how producers must manage them. Poultry owners should keep their birds away from wild ducks and geese and their droppings. Outdoor access for poultry should be limited, particularly as the state continues to see HPAI detections in wild bird populations.

Rodents and insects are also major biosecurity risks. Pests and rodents are known vectors of disease transmission. Effective pest management strategies must be implemented to prevent disease from spreading on the farm. Your biosecurity plan should include a documented integrated pest management (IPM) strategy that covers:

• Installing effective barriers like buried fencing and fine mesh screens to prevent wildlife intrusions.
• Creating a rodent and insect management plan including monthly inspections and integrated pest management techniques. This approach maintains effective control while reducing chemical dependency.
• Removing attractants like spilled feed and standing water. Regular monitoring helps detect and address pest issues before they become major problems.

When wildlife directly threatens your livestock, New York law provides specific remedies. If a bear is killing or worrying livestock or destroying an apiary on cultivated land, the landowner may take the bear at any time. The landowner is then required to contact the DEC promptly and to deliver the carcass to the DEC officer for disposal.

For rabies-vector species such as raccoons, bats, and skunks, stricter handling rules apply. Wildlife control operators must follow the directives of their DEC permits and the local county health department concerning the handling and disposal of bats, raccoons, and skunks, and any other directives about rabies. Livestock producers dealing with these species on their property should coordinate with a licensed wildlife control operator or their local DEC office rather than attempting removal independently.

Livestock guardian dogs can also play a meaningful role in deterring predators and wildlife from your operation. Learn more about their capabilities and management in this overview of facts about livestock guardian dogs.

Dead Animal Disposal Requirements in New York

Proper disposal of livestock carcasses is both a biosecurity necessity and a legal requirement in New York. Improper disposal can contaminate water sources, attract pests, and spread pathogens across your property and to neighboring farms.

New York Agriculture and Markets Law Section 377 establishes the baseline rule: the carcasses of large domestic animals, including but not limited to horses, cows, sheep, swine, goats, and mules, which have died otherwise than by slaughter, shall be buried at least three feet below the surface of the ground or otherwise disposed of in a sanitary manner by the owner. Such disposal shall be completed within seventy-two hours after the owner is directed to do so by any peace officer or designated representative of the commissioner.

In New York, a farm has 72 hours to have a removal service take away a dead animal. Beyond removal services, the other legally recognized disposal methods are burial, composting, and — under very limited circumstances — incineration. The other options are burial, incineration, and composting. Burial is relatively quick and easy and may be appropriate for emergency mass casualties such as a disease outbreak. But there are legal requirements farmers need to consider before going this route, many of which are outlined in NYSDEC Solid Waste rules NYCRR-NY 363-2.1(b).

Composting is an increasingly viable option for many New York operations. For effective composting, a base layer should be able to absorb leachate and allow air to enter. Woodchips — not sawdust — are ideal. Use about two feet of materials on all sides of the animal. If built correctly, the piles should reach 130 to 170 degrees Fahrenheit within 12 to 24 hours. If that temperature is maintained for five days, it will kill pathogens.

Regarding incineration, no livestock incineration equipment is legal in New York as of the time of the most recent guidance available from Cornell Pro-Dairy. Do not invest in incineration equipment without first confirming current DEC regulations with your county or regional DEC office, as this area of the rules continues to evolve.

Document each mortality and disposal method used to maintain biosecurity records and demonstrate regulatory compliance. This documentation is critical if your operation is ever subject to an inspection or if you need to demonstrate compliance during a disease investigation. Keep records of the date of death, the animal’s identification, the disposal method used, and the location of disposal.

For disease-related mortalities, contact NYSDAM’s Division of Animal Industry at (518) 457-3502 before disposal to determine whether the carcass must be tested or handled under special protocols. Outbreaks of animal disease trigger heightened regulatory oversight, movement restrictions, and mandatory reporting. Producers should maintain readiness for rapid response, including quarantine, testing, and coordination with state and local authorities.

Staying current with New York’s livestock biosecurity requirements takes ongoing attention, but the framework is manageable when broken down into its component parts. Register your premises, maintain your permits, document your protocols, control access to your operation, and handle mortalities promptly and lawfully. These actions protect your animals, your neighbors’ animals, and the broader agricultural economy that depends on disease-free livestock production across the state.
