Sec. 50.4  Classification of cattle, bison, captive cervids, and other livestock as infected, exposed, or suspect.

    (a) Cattle, bison, and captive cervids are classified as infected 
with tuberculosis on the basis of an intradermal tuberculin test applied 
by a Federal, State, or an accredited veterinarian or by other 
diagnostic procedure approved in advance by the Administrator.
    (b) Cattle, bison, and captive cervids are classified as exposed to 
tuberculosis when such cattle, bison, and captive cervids (1) are part 
of a known infected herd, or (2) are found to have moved from an 
infected herd before the time infection was disclosed in such herd and 
after the time such herd had apparently become infected, or (3) are 
found to have been exposed by virtue of nursing a reactor dam: Provided, 
That cattle, bison, and captive cervids classified as exposed to 
tuberculosis shall be removed direct to slaughter.
    (c) Cattle and bison are classified as suspects for tuberculosis 
based on a positive response to an official tuberculin test, in 
accordance with the ``Uniform Methods and Rules--Bovine Tuberculosis 
Eradication'' (incorporated into the regulations by reference in part 
77). Captive cervids are classified as suspects for tuberculosis in the 
same manner as cattle and bison.
    (d) The designated tuberculosis epidemiologist will determine 
whether livestock other than cattle, bison, or captive cervids are 
classified as exposed to tuberculosis by reason of association with an 
affected herd of cattle, bison, or captive cervids.
