Ch. 16 - Scrapie Eradication

100

Scrapie is a degenerative and eventually fatal disease affecting the central nervous systems of sheep and goats. This disease is a member of a class of diseases called transmissible spongiform encephalopathies (TSE's). The control of this disease is complicated because the disease has an extremely long incubation period without clinical signs. To control the spread of Scrapie within the United States , the Animal and Plant Health Inspection Service (APHIS), U.S. Department of Agriculture (USDA), administers regulations at 9 CFR part 79, which restrict the interstate movement of certain sheep and goats.

(Adopted January 6, 2005.)

101 In August of 2001 USDA published a final rule in the Code of Federal Regulations for the interstate movement of sheep and goats by requiring certain animal identification for sheep and goats moving interstate, by establishing a list of States that conduct an active State Scrapie program that is consistent with Federal requirements, by establishing requirements for moving sheep and goats interstate from those States and from States that do not conduct such programs, by reinstituting an indemnity program for certain sheep and goats affected by Scrapie, and by making other associated changes. These changes will help prevent the interstate spread of Scrapie, an infectious disease of sheep and goats. The compliance date for all requirements to identify animals that are not Scrapie- positive animals, suspect animals, high-risk animals, exposed animals, or animals from an infected or source flock is November 19, 2001. The compliance date for all requirements for the identification of commercial white faced breeding sheep less than 18 months of age and commercial breeding goats is February 18, 2002.

(Adopted January 6, 2005.)

102 In order that Mississippi retain “Scrapie Consistent” Status as defined in CFR Parts 54 and 79 “Scrapie in Sheep and Goats; Interstate Movement Restrictions and Indemnity Program; Final Rule” the following regulation is promulgated. States that are not listed as “Scrapie Consistent” will have the following restrictions imposed on interstate commerce from that state:

1. No breeding sheep can move out of an inconsistent state unless the Flock of origin is enrolled in the Scrapie Flock Certification Program (SFCP).

2. Sexually intact slaughter sheep under 18 months must either originate in an SFCP enrolled flock or be officially identified unless moving directly to slaughter or a terminal feedlot.

3. Slaughter sheep over 18 months must be officially identified and move on a CVI

4. Breeding and sexually intact exhibition goats that do not meet the definition of low risk can't move out of an inconsistent state unless the flock of origin is enrolled in the SFCP.

(Adopted January 6, 2005.)

Supervision Of The Scrapie Eradication Program

103 The Scrapie eradication program is a cooperative program between the Mississippi Board of Animal Health and APHIS and is supervised by full-time animal health veterinarians employed by the state or federal government.

Identification

105 Animals required to be officially identified shall have official identification applied upon, or before, departure from the current flock of origin by the flock owner or the owner's agent. If an animal was not identified prior to departing from its flock of birth or if its identification has been lost, then the animal must be identified upon, or before, departing from the current flock in which the animal resides and the flock of birth, or previous flock of origin, should be recorded, if known. No person shall apply a flock ID tag to an animal that has not resided in that flock. See definitions for allowable forms of identification.

1. Sheep

a. Sheep-official identification required. Sheep required to be officially identified include:

i. All sexually intact sheep, unless specifically excluded in these regulations;

ii. All sexually intact sheep for exhibition;

iii. All sheep over 18 months of age;

iv. All sheep residing in noncompliant flocks;

v. All exposed, suspect, positive and high-risk sheep; and

vi. Sexually intact sheep of any age imported into Mississippi , except as noted below

b. Sheep-official identification not required. Sheep that do not require official identification include:

i. Sheep under 18 months of age originating from outside the state of Mississippi moving into an approved terminal feedlot, and any sheep under 18 months of age moving directly to slaughter;

Restrictions On the Removal Of Official Identification

106 No person may remove or tamper with any approved means of identification required to be on sheep or goats, unless the identification must be removed for medical reasons, in which case new official identification must be applied to the animal as soon as possible and prior to commingling that could result in the loss of identity of the animal. A record documenting the change of official identification must be made.

For animals not born in the flock, records must include the flock-of-origin number or the previous owner's name and address, date of acquisition, a description of the animal (sheep or goat, and breed or class), and flock of birth, if known. When official ID tags are applied, it is recommended that the owner correlate official ID with production records, such as lambing dates, for all breeding animals. The owner shall maintain a record of the name and address of the market or buyer, the date, the number of animals sold, and a description of the animals (sheep or goat, and breed or class) for all animals moved from the flock.

(Adopted January 6, 2005.)

107.02 Record-keeping requirements for auction markets. Markets must collect a completed “Record of Ear Tags Applied” form from each seller presenting animals that require official identification. This form shall list existing tag numbers or the serial tag number applied at the sale.

(Adopted January 6, 2005.)

107.03 Record-keeping requirements for licensed sheep (livestock) dealers. The dealer must collect a completed “Record for Ear Tags Applied” form from the person from whom the dealer takes possession of the animals that require official identification. For animals that are resorted and sold, records must identify all potential buyers of any animal acquired. All records must be kept for five years and made available for inspection upon request.
