Animal Health, Feeds, and Livestock ID

​USDA Animal Disease Traceability

Animal disease traceability, or 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. Animal Disease Traceability is not a food safety tool, and it cannot prevent animal disease. It is a livestock-tracing tool necessary to efficiently respond to animal health disease events.

Identification requirements

Identification may be recorded directly on the certificate of veterinary inspection (CVI) or on an attached list.

  • Dairy cattle: All classes of dairy cattle require official individual identification, regardless of age. Dairy steers moving directly to slaughter require official identification, however the identification does not need to be recorded on the CVI.
  • Beef cattle (and bison): Sexually intact cattle greater than 18 months of age require official identification. If they are less than 18 months of age or moving directly to slaughter, they are exempt. Cattle of any age used for rodeo, recreational events, shows, and exhibition require identification.
  • Sheep: Scrapie ear tags are accepted. No identification required on market lambs less than 18 months of age.

Acceptable official individual identification

  • USDA silver “bright” tags (part of the National Uniform Eartagging System-NUES). ODA will provide these free of charge to producers.
  • Bangs calfhood vaccination tags.
  • 840 ID tags (also referenced as animal identification number-AIN). The tag has 15 digits beginning with 840, which is the numeric code for the USA. The tag comes in various sizes, shapes, and colors. Radio frequency identification (RFID) also is available. Producers need a premises identification number, available from ODA, to purchase these tags. Producers purchase these directly from commercial vendors (PIN number required).
  • Brands. A single iron hot brand will be allowed, when accepted by both the shipping and receiving states. Oregon has agreements in place for CA, ID, MT, NV, and UT. Individual identification is required, but animals may be shipped on brand assurance. Indicate on CVI that individual identification is in place.
  • Breed registry tattoos. Tattoos are allowed, when accompanied by breed registry papers and when accepted by both the shipping and receiving states.

Premises identification number (PIN)

Premises identification is another component of animal disease traceability. The number links livestock and poultry locations to a national database for better management of emergencies.

Benefits to livestock and poultry owners and operators with a national PIN:

  • Allows rapid notification of livestock and poultry stakeholders during an emergency
  • Helps prepare for animal health and food safety emergencies
  • Helps track animals in an emergency
  • Reduces the impact of an emergency
  • Allows producers to purchase commercially available 840 ID tags
  • Maintains or provides greater market access​

Ordering RFID tags

Oregon livestock may order tags directly from the Oregon Department of Agriculture (ODA) Animal Health Program using the Producer RFID tag order form.

A Premises Identification Number (PIN) must be included on the order form that matches the farm/ranch's address. PINs may be obtained by completing the premises registration application and returning it with the supplies order.​

​​​RFID reader loan

ODA has several RFID readers available to loan, free of charge, to Oregon livestock producers. The reader loan program is intended to provide producers an opportunity to evaluate the use of RFID in their operation without requiring an up-front investment in an RFID reader. RFID readers available for loan include the TruTest XRS2 VHF reader.
​UHF readers will hopefully be added to this program soon.
