(a) Has either had limited contact with the scrapie-positive animal, or
(b) Has been determined by a designated scrapie epidemiologist to be a low risk animal.
(2) An animal that resided on the premises of a scrapie source or infected flock or herd before the flock or herd completes the requirements of a flock plan.
(H) "Exposed flock" means a flock that contains an exposed or suspect female animal; or a flock or herd that once contained either an exposed or suspect female animal and the animal was neither tested for scrapie nor tested and found negative for scrapie.
(I) "Flock" means:

(N) "Post exposure management and monitoring plan (PEMMP)" means a written agreement signed by the owner, an accredited veterinarian (if one is employed) and a State or federal representative in which each participant agrees to undertake specific actions to reduce the risk of the occurrence of scrapie and to monitor for the occurrence of scrapie in the flock for at least five years after the last high-risk or scrapie-positive animal is removed or exposed to a scrapie-positive animal.
