subchapters B, C, and D of this chapter, and to perform functions 
required by cooperative State-Federal disease control and eradication 
programs.
    Administrator. The Administrator, Animal and Plant Health Inspection 
Service, United States Department of Agriculture, or any employee of the 
United States Department of Agriculture authorized to act in his or her 
stead.
    Animal. A sheep or goat.
    Animal and Plant Health Inspection Service (APHIS). The Animal and 
Plant Health Inspection Service of the United States Department of 
Agriculture.

    Breed associations and registries. Organizations which maintain the 
permanent records of ancestry or pedigrees of animals (including the

[[Page 265]]

and dam), individual identification of animals, and ownership of 
animals.
    Exposed animal. Any animal which has been in the same flock at the 
same time within the previous 60 months as a scrapie-positive animal, 
excluding limited contacts. Limited contacts are contacts between 
animals that occur off the premises of the flock, and do not occur 
during or immediately after parturition for any of the animals involved. 
Limited contacts do not include commingling (when animals concurrently 
share the same pen or same section in a transportation unit where there 
is uninhibited physical contact).
    Flock. All animals maintained on any single premises; and all 
animals under common ownership or supervision on two or more premises 
which are geographically separated, but among which there is an 
interchange or movement of animals.
    Flock plan. A written flock management agreement designed by the 
owner of a flock, an accredited veterinarian, and a Veterinary Services 
representative or State representative in which each participant agrees 
to undertake actions specified in the flock plan to control the spread 
of scrapie from, and eradicate scrapie in, an infected flock, source 
flock, or trace flock. The flock plan shall require an epidemiologic 
investigation to identify high-risk animals that must be removed from 
the flock, and shall include other requirements found necessary by the 
APHIS representative or State representative to control scrapie in the 
flock. These other requirements may include, but are not limited to, 
cleaning and disinfection of flock premises, education of the owner of 
the flock and personnel working with the flock in techniques to 
recognize clinical signs of scrapie and control the spread of scrapie, 
and maintaining records of animals in the flock.
    High-risk animal. An animal which is:
    (1) The progeny of a scrapie-positive dam;
    (2) Born in the same flock during the same lambing season as progeny 
of a scrapie-positive dam, unless the progeny of the scrapie-positive 
dam are from separate contemporary lambing groups (groups that are 
managed as separate units and are not commingled during lambing and for 
60 days following the date the last lamb was born, and that do not use 
the same lambing facility unless the lambing facility is cleaned and 
disinfected between lambings by removing all organic matter and spraying 
the lambing facility with a 2 percent sodium hydroxide solution or 0.5 
percent sodium hypochlorite solution); or
    (3) Born during the same lambing season as a scrapie-positive ewe or 
ram in a source flock or trace flock.
    Infected flock. Any flock in which an APHIS representative or a 
State representative has determined an animal to be a scrapie-positive 
animal after March 31, 1989. A flock will no longer be an infected flock 
after it has completed the requirements of a flock plan.
    Permit. An official document (VS Form 1-27) issued by an APHIS 
representative that indicates the following: the shipper's or 
consignor's name and address; the consignee's name and address; the 
State where the permit was issued; points of origin and destination of 
the animals being moved interstate; purpose of the movement; number and 
species of animals covered by the permit; whether the animals are from 
an infected flock or a source flock; transportation vehicle license 
number or other identification number; and seal number.
    Scrapie control pilot project. A pilot project authorized by the 
Administrator in writing, designed to test or improve program procedures 
or to facilitate research, in order to control and eradicate scrapie. In 
addition to APHIS, participants may include State animal health 
agencies, flock owners, and other parties as necessary.
    Scrapie-positive animal. An animal for which a diagnosis of scrapie 
has been made by the National Veterinary Services Laboratories, United 
States Department of Agriculture, or another laboratory authorized by 
the Administrator to conduct scrapie tests in accordance with this part, 
through histological examination of central nervous system samples from 
the animal for microscopic lesions in the form of neuronal vacuoles or 
spongy degeneration, or by the use of protease-resistant protein 
analysis or other confirmatory

[[Page 266]]

techniques used in conjunction with histological examination.
    Source flock. A flock in which an APHIS representative or a State 
representative has determined that at least two animals were born that 
were diagnosed as scrapie-positive animals at an age of 54 months or 
less. In order for the flock to be a source flock, the second scrapie-
positive diagnosis must have been made within 60 months of the first 
scrapie-positive diagnosis and after March 31, 1989. A flock will no 
longer be a source flock after it has completed the requirements of a 
flock plan.
    Source flock. A flock in which a Veterinary Services representative 
has determined that at least two animals, that were diagnosed as 
scrapie-positive animals at an age of 54 months or less, were born. In 
order to be a source flock, the second scrapie-positive diagnosis must 
be made within 60 months of the first scrapie-positive diagnosis. A 
flock will no longer be considered a source flock after it has completed 
the requirements of a flock plan.
    State. Each of the 50 States, the District of Columbia, the Northern 
Mariana Islands, Puerto Rico, and all territories or possessions of the 
United States.
    State representative. An individual employed in animal health 
activities by a State or political subdivision of a State, and who is 
authorized by the State or political subdivision to perform the function 
involved.
    Trace flock. A flock in which an APHIS representative or a State 
representative has determined that one animal was born that was 
diagnosed as a scrapie-positive animal at an age of 54 months or less. 
In order for the flock to be a trace flock, the scrapie-positive 
diagnosis must have been made after March 31, 1989. A flock will no 
longer be a trace flock after it has completed the requirements of a 
flock plan.
