Animal Disease Traceability (ADT)

Animal Disease Traceability (ADT) is a cooperative program that is jointly funded and administered by the United States Department of Agriculture (USDA) and the Texas Animal Health Commission.

Animal disease traceability, knowing where and when diseased and at-risk animals are or have been, is important to ensuring a rapid response when animal disease events take place. Although animal disease traceability does not prevent disease, an efficient and accurate traceability system reduces the number of animals and response time involved in a disease investigation; which, in turn, reduces the economic impact on owners and affected communities.

Before an official identification device can be ordered, applicators and/or owners must be assigned a nationally unique number. Once the nationally unique number has been assigned, the applicator and/or owner will provide the number to the official tag distributor.

There are three nationally recognized identification number options; Premised Identification Numbers (PINs), Location Identification Numbers (LIDs), and Scrapie Flock Identification Numbers. To learn more about nationally unique numbers click here.

To request a PIN, LID, or scrapie flock ID contact the TAHC Animal Disease Traceability Team at animal_id@tahc.texas.gov or 512-719-0733.

Official identification is fundamental to traceability and animal disease programs. Cattle, sheep, goats, swine and other livestock are subject to official identification requirements as outlined by the USDA and TAHC regulations.

Veterinarians interested in becoming an Animal Identification (AIN) device manager (tag distributor) is invited to read the USDA-APHIS AIN Device Manager Guidance Document.

The Texas Animal Health Commission (TAHC) has received a limited number of no-cost Radio Frequency Identification (RFID) ear tags from the USDA to distribute to Texas accredited veterinarians and cattle producers for use in replacement breeding cattle.

The complimentary RFID tags are to be used as an alternative to silver metal Brite tags and orange metal Official Calfhood Vaccination (OCV) tags.

Texas accredited veterinarians and cattle producers interested in ordering RFID tags at no-cost may submit their request to the TAHC Animal Disease Traceability (ADT) Department beginning Monday, January 11, 2021 at 8:00 AM.

• Only Texas accredited veterinarians and cattle producers may order the free RFID tags from the Texas allocation.
• These RFID tags are only intended for use in replacement stock.
• Two types of tags are available to order: white “840” button tags and orange “840” calfhood vaccination (OCV) button tags. Both RFID tags are low frequency tags. Veterinarians may receive both white and orange tags, while cattle producers may only receive white tags.
• Currently, no ultra-high frequency tags are available through this program.
• Tags are ordered in bags of 100 and will be made available for pick up at a TAHC region offices.
• RFID tag inventory may include more than one brand of tag. A specific brand cannot be requested.
• RFID tag readers are not required to distribute or apply 840-AIN RFID ear tags.

To place your order, contact the TAHC ADT Department by phone, 512-719-0733, or email, animal_id@tahc.texas.gov. TAHC staff will process your request in the order it is received. In the event of high call volume, please leave a voicemail and our staff will return your call in the order it is received.

Once the Texas tag allotment is depleted, no additional tags may be provided to the state. The TAHC will provide the most current information on availability and distribution on this webpage.
