§ 50.6 Identification of animals to be destroyed because of tuberculosis. ( a ) Livestock to be destroyed because of tuberculosis must be identified as follows: ( 1 ) Livestock classified as reactors for tuberculosis must be identified within 15 days after being classified as reactors, except that the veterinarian in charge may extend the time limit for identification to 30 days when he or she receives a request for such an extension prior to the expiration date of the original 15-day period allowed and circumstances beyond the control of the owner warrant such an extension, and the Administrator may extend the time limit for identification beyond 30 days upon request in specific cases when circumstances beyond the control of the owner warrant such an extension.
( 2 ) Livestock other than reactors for tuberculosis that are to be destroyed because of tuberculosis must be identified prior to movement from the premises of origin to the place of destruction.
( b ) *Reactor cattle, bison, and captive cervids.* Reactor cattle, bison, and captive cervids must be identified by branding the letter “T,” at least 5 by 5 centimeters (2 by 2 inches) in size, high on the left hip near the tailhead and by attaching to the left ear an approved metal eartag bearing a serial number and the inscription “U.S. Reactor,” or a similar State reactor tag. Reactor cattle, bison, and captive cervids may be moved interstate to slaughter without branding if they are permanently identified by the letters “TB” tattooed legibly in the left ear, they are sprayed on the left ear with yellow paint, and they are either accompanied by an APHIS or State representative or moved directly to slaughter in vehicles closed with official seals. The official seals must be applied and removed by an APHIS representative, State representative, accredited veterinarian, or an individual authorized for this purpose by an APHIS representative.
( c ) *Exposed cattle, bison, and captive cervids.* Exposed cattle, bison, and captive cervids must be identified by branding the letter “S,” at least 5 by 5 centimeters (2 by 2 inches) in size, high on the left hip near the tailhead and by attaching to either ear an approved metal eartag bearing a serial number. Exposed cattle, bison, and captive cervids may be moved interstate to slaughter without branding if they are either accompanied by an APHIS or State representative or moved directly to slaughter in vehicles closed with official seals. The official seals must be applied and removed by an APHIS representative, State representative, accredited veterinarian, or an individual authorized for this purpose by an APHIS representative.
( d ) *Other exposed livestock.* Livestock other than cattle, bison, or captive cervids that are destroyed under the provisions of § 50.3 must be identified by tagging with a serially numbered metal eartag attached to either ear. All such animals to be destroyed must be transported to the place of destruction in vehicles closed with seals provided by APHIS or shall be accompanied to the place of destruction by an APHIS or State representative: *Provided, however,* that animals destroyed and disposed of under the direct supervision of an APHIS or State representative on the premises where they were exposed do not require individual identification.
