Animal. Any farmed or captive cervid. Animal identification. A device or means of animal identification approved for use under this part by APHIS. Examples of animal identification devices that APHIS has approved are listed in § 55.25 . Animal identification number (AIN). A numbering system for the official identification of individual animals in the United States. The AIN contains 15 digits, with the first 3 being the country code (840 for the United States), the alpha characters USA, or the numeric code assigned to the manufacturer of the identification device by the International Committee on Animal Recording. Approved State CWD Herd Certification Program. A program operated by a State government for certification of cervid herds with respect to CWD that the Administrator has determined to meet the requirements of § 55.23(a) . Commingled, commingling. Animals are commingled if they have direct contact with each other, have less than 10 feet of physical separation, or share equipment, pasture, or water sources/watershed.

Herd plan. A written herd and/or premises management agreement developed by APHIS in collaboration with the herd owner, State representatives, and other affected parties. The herd plan will not be valid until it has been reviewed and signed by the Administrator, the State representative, and the herd owner. A herd plan sets out the steps to be taken to eradicate CWD from a CWD-positive herd, to control the risk of CWD in a CWD-exposed or CWD-suspect herd, or to prevent introduction of CWD into that herd or any other herd. A herd plan will require specified means of identification for each animal in the herd; regular examination of animals in the herd by a veterinarian for clinical signs of disease; reporting to a State or APHIS representative of any clinical signs of a central nervous system disease or chronic wasting condition in the herd; maintaining records of the acquisition and disposition of all animals entering or leaving the herd, including the date of acquisition or removal, name and address of the person from whom the animal was acquired or to whom it was disposed; and the cause of death, if the animal died while in the herd.

A herd plan may be reviewed and changes to it suggested at any time by any party signatory to it, in response to changes in the situation of the herd or premises or improvements in understanding of the nature of CWD epidemiology or techniques to prevent its spread. The revised herd plan will become effective after it is reviewed by the Administrator and signed by the Administrator, the State representative, and the herd owner.

Herd status. The status of a herd assigned under the CWD Herd Certification Program in accordance with § 55.24 , indicating a herd's relative risk for CWD.

Official animal identification. A device or means of animal identification approved for use under this part by APHIS to uniquely identify individual animals. Examples of approved official animal identification devices are listed in § 55.25 . The official animal identification must include a nationally unique animal identification number that adheres to one of the following numbering systems: (1) National Uniform Eartagging System. (2) Animal identification number (AIN). (3) Premises-based number system. The premises-based number system combines an official premises identification number (PIN), as defined in this section, with a producer's livestock production numbering system to provide a unique identification number. The PIN and the production number must both appear on the official tag. (4) Any other numbering system approved by the Administrator for the identification of animals in commerce.

The premises identification number may consist of: (1) The State's two-letter postal abbreviation followed by the premises' assigned number; or (2) A seven-character alphanumeric code, with the right-most character being a check digit. The check digit number is based upon the ISO 7064 Mod 36/37 check digit algorithm. Trace back herd. A herd in which a CWD-positive animal formerly resided. Trace forward herd.
