54-2717. Flock, defined.

Flock means a group of sheep or goats or a mixture of both species, residing on the same premises, and all animals under common ownership or supervision on two or more premises with animal interchange between the premises. Changes in ownership of part or all of a flock do not change the identity of the flock or the regulatory requirements applicable to the flock. Animals maintained temporarily on a premises for activities such as shows and sales or while in marketing channels are not a flock. More than one flock may be maintained on a single premises if:

(1) The flocks are enrolled as separate flocks in the scrapie flock certification program; or

(2) The department or APHIS representative determines, based upon examination of flock records, that:

(a) There is no interchange of animals between the flocks;

(b) The flocks never commingle and are kept at least thirty feet apart at all times or are separated by a solid wall through, over, or under which fluids cannot pass and through which contact cannot occur;

(c) The flocks have separate flock records and identification;

(d) The flocks have separate lambing facilities, including buildings and pastures, and a pasture or building used for lambing by one flock is not used by the other flock at any time; and

(e) The flocks do not share equipment without cleaning and disinfection in accordance with 9 C.F.R. 54.7(e). Additional guidance on acceptable means of cleaning and disinfection is also available in the federal scrapie flock certification program standards and the federal Scrapie Eradication Uniform Methods and Rules.
