Chapter 16-89 WAC

SHEEP AND GOAT SCRAPIE DISEASE CONTROL


NEW SECTION
WAC 16-89-005
Purpose.

(1) Scrapie is an insidious, fatal neurological disease of sheep and goats. The disease agent has not been definitively characterized. The incubation period is very long, usually over eighteen months. There is no treatment, and the disease is always fatal. Currently there is no live animal diagnostic test for the presence of the disease. Diagnosis is made by observation of characteristic signs in the live animal and is confirmed by post-mortem examination of brain tissue.

(2) The United States Department of Agriculture (USDA) Voluntary Scrapie Flock Certification program is designed to monitor flocks and certify the scrapie status of the animals that are enrolled in the program. Any sheep or goat owner may apply to the USDA Veterinary Services area office in Olympia, Washington to participate in this program. It requires individual animal identification, keeping of good records, the reporting of acquisitions and deaths of animals to the USDA, Animal and Plant Health Inspection Service (APHIS) veterinary representative and annual inspections by the APHIS veterinary representative. At the end of five years, if all criteria have been met, the flock may be certified as being free of scrapie, as long as the flock remains on the USDA Voluntary Scrapie Flock Certification Program.

(3) The Washington state scrapie program requires that every blackface or blackface crossbred breeding sheep which is one year or older be identified with a Washington state flock identification number. Ninety seven percent of all diagnosed scrapie cases in the United States have occurred in blackfaced breeds or crosses although whitefaced individuals can occasionally be susceptible. Blackface or blackface crossbred breeding stock of any age must be identified before transfer of ownership or possession. Few records need to be maintained, no reports of deaths or new acquisitions are required. The program is strictly a control and eradication program and does not lead to flock certification.

Enrollment in the USDA Voluntary Scrapie Flock Certification Program will fulfill the requirements of the Washington state program.

Definitions.

For the purposes of this chapter:

(1) "Director" means the director of agriculture of the state of Washington or his or her duly authorized representative.

(2) "Department" means the Washington state department of agriculture.

(3) "Blackface breeding stock" means intact male or female sheep of blackface breeds and intact male or female sheep that are crosses of blackface and other breeds of sheep.

(4) "Flock" means a number of animals of sheep or goat species which are kept, fed and herded together having single or multiple ownership. The term "flock" shall be interchangeable with the term "herd" and shall apply to purebred and commercial sheep.

(5) "Washington flock identification number" means a unique flock identification number assigned to the owner or owners of each flock of blackface breeding sheep in the state of Washington.

(6) "Official individual identification" means the unique identification of individual animals with an alphanumeric number applied as a tamper proof tag, tattoo, electronic device, or other tag approved by USDA or the director. The Washington flock identification number can serve as the official individual identification number if it contains a unique individual animal number in addition to the flock number.

(7) "Scrapie" means a transmissible spongiform encephalopathy that is a nonfebrile, transmissible, insidious, degenerative disease affecting the central nervous system of sheep and goats.

(8) "Scrapie exposed animal" means any animal, which has been in the same flock at the same time within the previous sixty 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 up to sixty days after parturition for any of the animals involved. Limited contacts do not include commingling or transportation to other flocks for the purposes of breeding. Examples of limited contacts include incidental contact in the show/sales ring. (See Appendix III of USDA's Voluntary Scrapie Flock Certification Program.)

(9) "Scrapie high risk animal" means an animal determined by epidemiologic investigation to be a high risk for developing clinical scrapie because the animal was the progeny of a scrapie-positive dam, was born in the same contemporary lambing group as a scrapie-positive animal or was born in the same contemporary lambing group as progeny of a scrapie-positive dam. Based upon evidence from the latest research information available and upon recommendation of the state scrapie certification board, animals that fit the criteria for high risk animals may be exempted by the director as high risk animals if they are determined by genetic testing to be QR or RR at the 171 codon or are determined by other recognized testing procedures to pose no risk.

(10) "Scrapie infected flock" means any flock in which a scrapie-positive animal has been identified by a state or federal animal health official.

(11) "Scrapie positive animal" means an animal for which a diagnosis of scrapie has been made by the National Veterinary Services Laboratories, USDA, laboratories accredited by the American Association of Veterinary Laboratory Diagnosticians (AAVLD) or another laboratory authorized by state or federal officials to conduct scrapie tests through histological examinations of central nervous system or by other diagnostic procedures approved for scrapie diagnosis by USDA. Animals diagnosed by experimental tests for abnormal prion will not be considered infected animals for the purposes of this rule.

(12) "Scrapie source flock" means a flock in which an animal was born and subsequently diagnosed as scrapie-positive at less than fifty-four months of age.

(13) "Voluntary scrapie flock certification program" means a national voluntary program for classification of flocks relative to scrapie.

NEW SECTION
WAC 16-89-020
Identification of blackface breeding stock.

(1) The state veterinarian will designate the form and content of the Washington state flock identification number, approve identification devices for utilization of the flock identification number, assure availability of flock identification devices, and assign Washington flock identification numbers to owners or possessors of blackface breeding stock.

(2) Owners and possessors of blackface breeding stock will bear the costs of obtaining the identification devices and placing the device in or on the animal except the department may provide tamper proof eartags to 4-H, FFA or other organized youth projects dependent upon the availability of funds. The department may also provide such tags for cooperative research programs and under the provisions of other interagency agreements.

(3) All owners or possessors of blackface breeding stock in Washington state must identify all blackface breeding stock in the flock which are one year of age or older with a Washington state flock identification number. Blackface breeding stock of any age will be identified with a flock identification number before transfer of ownership or possession.

(4) Blackface breeding stock imported into the state will be identified with a flock identification number within sixty days after entry into the state.

(5) Blackface breeding stock of any age must be identified with a flock identification number prior to movement of such sheep from the premises of origin for show, sale, purchase or other movement.

(6) Blackface breeding stock sold within the state must retain the original flock identification number. In the event an animal loses a flock identification device, the owner of the animal must reidentify the animal with his or her flock identification number and must maintain records to document the original and new flock identification numbers.

(7) Acceptable devices for application of the flock identification number to blackface breeding stock will include: Tamper proof ear tags bearing the flock identification number, legible tattoos bearing the flock identification number, electronic devices with owner records correlated to the flock identification number, approved voluntary scrapie flock certification program identification devices, and other identification devices approved by the state veterinarian.

(8) Blackface animals exempt from the state requirement for identification with a state flock identification number will include:

(a) Neutered animals.

(b) Sexually intact market lambs consigned directly to an approved slaughter facility or consigned directly to an approved lamb feedlot for finish feeding for slaughter only. Animals in approved feedlots may be removed only to approved slaughter facilities or other approved feedlots. Owners or livestock dealers delivering market lambs to Washington state slaughter facilities or approved feedlots must provide to the managers of such facilities the Washington flock numbers from which the market lambs have originated. A record of the flock numbers must be maintained for two years and available for review by the director.

(c) Lambs under one year of age that have not been sold or transferred to the possession of another person or entity.

(d) Sheep over one year of age that have not been sold or transferred to the possession of another person where management practices preclude applying the identification devices within the flock. This exemption must be specifically approved by the state veterinarian for each flock.

(e) Blackface animals within a flock enrolled in the federal Voluntary Scrapie Flock Certification Program.
