Administrator. The Administrator, Animal and Plant Health Inspection Service, or any person authorized to act for the Administrator.

Affected herd. A herd of livestock in which there is strong and substantial evidence that Mycobacterium bovis exists.

Animal and Plant Health Inspection Service (APHIS). The Animal and Plant Health Inspection Service of the United States Department of Agriculture.

Animal identification number (AIN). A numbering system for the official identification of individual animals in the United States that provides a nationally unique identification number for each animal. The AIN consists of 15 digits, with the first 3 being the country code (840 for the United States or a unique country code for any U.S. territory that has such a code and elects to use it in place of the 840 code). The alpha characters USA or the numeric code assigned to the manufacturer of the identification device by the International Committee on Animal Recording may be used as an alternative to the 840 or other prefix representing a U.S territory; however, only the AIN beginning with the 840 or other prefix representing a U.S. territory will be recognized as official for use on AIN tags applied to animals on or after March 11, 2015. The AIN beginning with the 840 prefix may not be applied to animals known to have been born outside the United States.

APHIS representative. An individual employed by APHIS who is authorized to perform the function involved.

Area veterinarian in charge. The veterinary official of APHIS who is assigned by the Administrator to supervise and perform the official animal health work of APHIS in the State concerned.

Epidemiologic investigation. An investigation that is conducted by a State in conjunction with APHIS representatives, in which an official test for tuberculosis is conducted on all livestock in any tuberculosis-affected herd in a State or zone, all livestock in any herd into which livestock from the affected herd have been moved, all potential tuberculosis source herds, and all livestock herds and animals that are likely to have been exposed to the affected herd.

Herd. Except for livestock assembled at feedlots, any group of livestock maintained for at least 4 months on common ground for any purpose, or two or more groups of livestock under common ownership or supervision, geographically separated but that have an interchange or movement of livestock without regard to health status, as determined by the Administrator.

Interstate. From one State into or through any other State.

Interstate certificate of veterinary inspection (ICVI). An official document issued by a Federal, State, Tribal, or accredited veterinarian certifying the inspection of animals in preparation for interstate movement.

(1) The ICVI must show:

(i) The species of animals covered by the ICVI;

(ii) The number of animals covered by the ICVI;

(iii) The purpose for which the animals are to be moved;

(iv) The address at which the animals were loaded for interstate movement;

(v) The address to which the animals are destined; and

(vi) The names of the consignor and the consignee, and their addresses if different from the address at which the animals were loaded or the address to which the animals are destined.

(vii) Additionally, unless the species-specific requirements for ICVIs provide an exception, the ICVI must list the official identification number of each animal, except as provided in paragraph (2) of this definition, or group of animals moved that is required to be officially identified, or, if an alternative form of identification has been agreed upon by the sending and receiving States, the ICVI must include a record of that identification. If animals moving under a GIN also have individual official identification, only the GIN must be listed on the ICVI. An ICVI may not be issued for any animal that is not officially identified, if official identification is required. If the animals are not required by the regulations to be officially identified, the ICVI must state the exemption that applies (e.g., the cattle and bison do not belong to one of the classes of cattle and bison to which the official identification requirements of this part apply). If the animals are required to be officially identified but the identification number does not have to be recorded on the ICVI, the ICVI must state that all animals to be moved under the ICVI are officially identified.

(2) As an alternative to recording individual animal identification on an ICVI, if agreed to by the receiving State or Tribe, another document may be attached to provide this information, but only under the following conditions:

(i) The document must be a State form or APHIS form that requires individual identification of animals, or a printout of official identification numbers generated by computer or other means;

(ii) A legible copy of the document must be attached to the original and each copy of the ICVI;

(iii) Each copy of the document must identify each animal to be moved with the ICVI. The document must not contain any information pertaining to other animals; and

(iv) The following information must be included in the identification column on the original and each copy of the ICVI:

(A) The name of the document; and

(B) Either the unique serial number on the document or both the name of the person who prepared the document and the date the document was signed.
