Livestock Biosecurity Requirements in Oregon Every Producer Should Know

Oregon’s agricultural economy depends on healthy livestock, and that health starts with biosecurity. Practicing biosecurity protects you and your animals from disease transmission, including zoonotic diseases that can be transmissible between humans and animals. Whether you raise cattle on Eastern Oregon rangeland or manage a small goat operation west of the Cascades, the rules governing how you protect your herd carry real legal and financial weight.

This guide walks you through the core livestock biosecurity requirements in Oregon — what the Oregon Department of Agriculture (ODA) expects, what state law mandates, and what practical steps you need to take to stay compliant and keep your animals safe.

What Is Livestock Biosecurity and Why It Matters in Oregon

Biosecurity refers to the set of practices and protocols designed to prevent the introduction and spread of infectious diseases on a livestock operation. Implementing biosecurity practices on your farm can protect livestock from infectious diseases, pests, and other harmful agents, and practicing these measures is essential in maintaining the health and productivity of animals while protecting the sustainability of the entire agricultural community.

The key principles of biosecurity are isolation, traffic control, and sanitation. These three pillars form the foundation of every ODA-recommended practice and every state-level compliance expectation for Oregon producers.

Oregon’s geography makes biosecurity especially critical. Oregon’s wet climate, especially west of the Cascades, can foster bacteria and parasites. On top of that, Oregon’s abundant wildlife — including deer, coyotes, and wild birds — can carry diseases, making secure fencing, netting, and rodent control critical to prevent disease transmission.

Biosecurity can be important in preventing disease introduction to your farm, reducing disease spread on or between farms, improving animal health and productivity, safeguarding public health, and promoting economic benefits through reducing costs associated with disease outbreaks and production losses.

Livestock operations are at risk of various animal disease threats. Work with your veterinarian to develop a plan for maintaining vaccinations and routine health checks, and monitor and report animals that show signs of illness to your veterinarian immediately. You can also find additional guidance through the livestock disease reporting requirements in Colorado for a comparative look at how neighboring western states approach animal health obligations.

Premises Registration and Identification Requirements in Oregon

One of the foundational administrative steps for Oregon livestock producers is registering your premises with the ODA and obtaining a Premises Identification Number (PIN). Animal disease traceability — knowing where diseased and at-risk animals are, where they’ve been, and when — is very important to ensure a rapid response when animal disease events take place. An efficient and accurate animal disease traceability system helps reduce the number of animals involved in an investigation, reduces the time needed to respond, and decreases the cost to producers and the government.

A Premises Identification Number (PIN) must be included on the order form that matches the farm or ranch’s address. PINs may be obtained by completing the premises registration application and returning it to the Oregon Department of Agriculture. If you move your operation to a new location, a producer who moves their farm’s location needs to apply for a new PIN.

Premises IDs are required for producers to order official RFID identification tags directly from manufacturers. These tags play a central role in Oregon’s animal disease traceability framework. There are several forms of RFID/EID tags available to producers to purchase, several of which count as official identification according to the USDA Animal Disease Traceability (ADT) program for interstate movement of livestock. Oregon livestock producers may order RFID/EID tags directly from tag manufacturers, and the fifteen-digit number should begin with 840 to ensure they count as official identification.

Premises registration allows rapid notifications to livestock and poultry stakeholders during an emergency and helps prepare for animal health and food safety emergencies. In addition to the PIN, cattle owners must get a brand inspection certificate for specific events, such as when cattle are moving out of state or are sent to a slaughterhouse or auction market. Learn more about how that process works in our detailed guide on brand inspection requirements in Oregon.

Biosecurity Plan Requirements in Oregon

Oregon does not universally mandate a written biosecurity plan for all livestock operations under routine conditions — but having one in place is strongly encouraged and becomes a legal requirement in specific circumstances. On-farm biosecurity practices and enhanced biosecurity mitigations are the basis for the Secure Food Supply plans and permitted movements during a disease outbreak, and developing a site-specific biosecurity plan is a critical step in the process toward implementing a Secure Food Supply plan.

If you want to participate in Oregon’s Secure Food Supply (SFS) program — which gives you the best chance of continuing to move animals and products during a foreign animal disease (FAD) outbreak — a written biosecurity plan is required. To enroll in the ODA Secure Food Supply program, you must either have ODA or a licensed, accredited veterinarian complete a biosecurity audit and submit the applicable Self Assessment Checklist for Enhanced Biosecurity, or review the appropriate commodity-specific Secure Food Supply plan and work with your veterinarian to develop or enhance and implement your biosecurity processes to satisfy plan standards — which includes a written biosecurity plan.

The ODA provides commodity-specific resources to help you build a compliant plan. Resources are available for beef producers, milk producers, pork producers, poultry producers, sheep producers, and goat producers — including customizable templates for writing biosecurity plans and self-assessment checklists for enhanced biosecurity.

In the event of an FAD outbreak, movement of animals and animal products is likely to be restricted to prevent the outbreak from spreading. Yet for producers to maintain continuity of business, it is critical to be able to move animals and animal products to the next stage of production. The Secure Food Supply plans provide animal producers with guidance to proactively prepare for an FAD outbreak.

Participating in a Secure Food Supply plan offers producers the best opportunity to move their animals and animal products during an FAD event. You can also review how other states structure these obligations — for example, see livestock disease reporting requirements in California and livestock disease reporting in Illinois for comparison.

Animal Isolation and Movement Control Requirements in Oregon

Controlling how animals move onto, off of, and around your property is one of the most direct ways to prevent disease introduction. Oregon’s ODA and state law set clear expectations here.

No livestock that are affected with or that have been known to be exposed to any infectious, contagious, or communicable disease shall be shipped or in any manner moved or transported into Oregon except as authorized. Except as otherwise provided, all livestock transported or moved into Oregon are required to obtain an import permit from the Department before entry.

When bringing animals onto your Oregon operation from another state, you generally must obtain a Certificate of Veterinary Inspection (CVI) or a grazing permit before they enter. These documents ensure that incoming animals are healthy and have not been exposed to contagious diseases.

For animals already on your property, isolation of new arrivals is a core requirement. Keep new or returning animals quarantined for at least 2–4 weeks before integrating them with the herd. ODA guidance goes further: isolate livestock that have been to shows, fairs, or other gathering activities for 4 weeks.

When moving animals within Oregon, you should also be aware of brand inspection requirements. The ODA enforces brand inspection for cattle in several situations, such as when they are sold or moved across state lines. See our guide on brand inspection requirements in Washington for a look at how a neighboring state handles similar movement controls. For livestock trailer compliance when transporting animals, you may also find it useful to review livestock trailer requirements in Nevada and livestock trailer requirements in Pennsylvania.

Limiting the movements of animals on and off your farm can help reduce the risk of introducing or spreading disease. If animals need to be moved, quarantine new arrivals to monitor for signs of illness, only purchase animals from reputable sources, and if possible, avoid mixing livestock from different sources and of different species.

Visitor, Vehicle, and Equipment Sanitation Rules in Oregon

People, vehicles, and equipment are among the most common vectors for pathogen introduction on a livestock operation. Oregon’s ODA guidance establishes specific expectations for how you manage these entry points.

Visitors can unknowingly carry harmful pathogens on their clothes, shoes, or equipment. To limit risk, restrict access to your farm as much as possible, and if visitors must enter, ensure they wear clean protective gear such as boots, coveralls, and gloves, and provide hand sanitizers or footbaths at entry points.

Monitor and limit the movement of vehicles, people, and equipment entering and exiting your farm. This includes service providers, feed delivery drivers, veterinarians, and anyone else who may have had contact with other livestock operations before arriving at yours.

For equipment and vehicles that have been used around animals, the ODA is specific about cleaning protocols. After moving animals, clean and disinfect all equipment before using it again: saturate by submersion or spray with 10 percent bleach (sodium hypochlorite), 1% Virkon S (DuPont), or other applicable disinfectants per label instructions.

• Footwear: Remove all visible organic debris from items to be disinfected such as cages, feeding equipment, waterers, and footwear. Wash items thoroughly with soap and water, rinse well, and let dry. Allow prolonged exposure to sunlight when possible. Items made of organic material, such as wood, are best discarded or burned.
• Hand hygiene: After handling animals, their feed, or equipment, reduce the spread of harmful bacteria and viruses by washing your hands thoroughly with soap and water, and avoid touching your face after handling livestock. Use hand sanitizers when soap and water aren’t available.
• Vehicles and trailers: Regularly disinfect items that encounter animals, including feeders, trailers, and vehicles.

If you have farm employees, their training is part of your compliance obligation. If you have employees or others working on the farm, ensure they are well-trained in proper biosecurity practices and ensure everyone understands the importance of hygiene and safety measures that will protect themselves and the animals on the farm. Conduct regular biosecurity training sessions on how to safely handle animals.

Wildlife and Pest Control Obligations in Oregon

Oregon’s diverse wildlife population is a persistent disease transmission risk for livestock producers. Managing the interface between your animals and local wildlife is both a biosecurity best practice and an implicit regulatory expectation under ODA’s disease prevention framework.

Oregon’s abundant wildlife — including deer, coyotes, and wild birds — can carry diseases, and secure fencing, netting, and rodent control are critical to prevent disease transmission. This is particularly relevant for poultry operations facing avian influenza pressure, but it applies equally to cattle, sheep, goat, and swine operations.

Your facility design and maintenance practices should reflect these risks:

• Perimeter fencing: Maintain fencing that physically separates your livestock from wildlife, particularly deer and feral pigs that may carry brucellosis or other transmissible diseases.
• Feed and water security: Store feed in sealed containers and covered structures to prevent wildlife and rodent access. Open feed sources attract animals that can contaminate feed with pathogens.
• Rodent control: Disposal and storage buildings should be fly-tight and constructed to exclude rats, other rodents, and vermin. While this standard applies specifically to carcass disposal facilities, the principle extends to all livestock housing and feed storage areas.
• Netting for poultry: Use bird netting or enclosed housing to limit contact between domestic poultry and wild birds, which are a primary vector for highly pathogenic avian influenza (HPAI).

Report any unusual illnesses or deaths to your veterinarian or the Oregon State Veterinarian’s Office at 503-986-4711 or email AHHotline@oda.oregon.gov. By state law, certain animal diseases must be reported to the State Veterinarian’s Office. The full list is identified in ODA’s Veterinary Disease Reporting Page.

Livestock guardian animals can also play a role in deterring wildlife from your operation. For more on their role in herd protection, see our overview of facts about livestock guardian dogs.

Dead Animal Disposal Requirements in Oregon

Oregon has specific statutory requirements governing how and when you must dispose of livestock carcasses. These rules exist to protect groundwater, surface water, neighboring properties, and the broader livestock population from secondary disease exposure.

Improper disposal of animal carcasses can pollute groundwater and surface water and can jeopardize the health of livestock, wildlife, and pets. Carcass disposal must be safe for animals and the environment, and people must comply with state law. Some counties also have their own disposal-related ordinances.

The core timing requirement under Oregon law is clear: animal carcasses within one-half mile of any dwelling or within one-quarter mile of any running stream of water must be disposed of as soon as possible, but no later than 15 hours after the time of death or discovery (ORS 601.140).

Oregon law under ORS Chapter 602 governs dead animal disposal and outlines several approved methods. The ODA’s Natural Resources Program administers these requirements. Approved disposal methods for livestock carcasses in Oregon generally include:

1. Burial: On-site burial is permitted in many areas, but must be conducted away from water sources and in compliance with depth requirements to prevent groundwater contamination and scavenger access.
2. Rendering: If you are unable to haul animals yourself or prefer to use a hauling service, ODA maintains a list of haulers licensed in Oregon. Licensed rendering facilities must meet specific construction and operational standards under ORS 601.
3. Landfill disposal: ODA maintains a list of landfills and transfer stations that accept animal carcasses.
4. Burning: Open burning of carcasses may be permitted in some jurisdictions but is subject to Oregon Department of Environmental Quality (DEQ) air quality rules and local fire regulations.
5. Composting: On-farm composting of livestock mortality is permitted under ODA guidelines when done correctly, using proper carbon-to-nitrogen ratios and monitoring protocols.

For operations that process carcasses on-site, all storing, skinning, and dismembering of dead bodies, carcasses, or parts of animals must be done within a building on the premises in such a manner that no public annoyance or nuisance is caused by the unsightly appearance or stench.

Proper carcass disposal also intersects with your biosecurity obligations. Carcasses left exposed can attract the same wildlife — coyotes, ravens, vultures — that may then spread pathogens to your living herd. Prompt, compliant disposal closes this loop. For a look at how disease reporting and mortality management intersect in another state, see our guide on livestock disease reporting in Florida.

For full guidance, the ODA recommends consulting the Landowner’s Guide to Managing Livestock Mortality, available through the ODA Natural Resources Program, and contacting your county extension office for any local ordinances that may apply to your specific location. You can reach the Oregon State Veterinarian’s Animal Health Hotline at 503-986-4711 or by email at AHHotline@oda.oregon.gov with questions about any aspect of your biosecurity or disposal obligations.
