| (a) All flocks determined to be infected (as per definition
of a scrapie positive animal in 60.1) shall be placed under quarantine.
(1) All animals and the flock shall be identified.
(A) Red tags for positive or QQ animals.
(B) White tags for all other animals.
(2) The following options shall be offered to the owner.
(A) Standard flock plan
(B) Pilot project flock plan
(C) Post-exposure, management, and monitoring flock plan
(D) Complete depopulation of the flock with indemnity (while
funds are available)
(E) Flocks whose owners decline the options listed in subparagraphs
(A)-(D) of this paragraph will be designated as non-compliant and remain under
quarantine until the requirements for quarantine release are met.
(b) All flocks containing animals suspicious of scrapie, and
source flocks, will be placed under hold order and investigated pending final
determination:
(1) Scrapie suspect animals and animals suspected of other
neurological or chronic debilitating disease are required to be made available
for destruction (depending on the decision of the Designated Scrapie Epidemiologist)
so that diagnostic specimens can be collected and submitted to an APHIS approved
laboratory for diagnostic purposes.
(2) The Designated Scrapie Epidemiologist for any of the following
reasons may remove the suspect designation, of animals reported as positive
on the live animal test:
(A) If the animal is not showing clinical signs of scrapie,
is over 18 months of age, is negative on the third eyelid test, and is RR
at the 171 codon on the genotype test; or,
(B) An epidemiological investigation shows the animal is not
likely to be infected and the third eyelid test cannot be done due to lack
of sufficient tissue; or,
(C) The animal is purchased for diagnostic purposed, is sacrificed,
and is negative on the histopathological tests conducted on tissues submitted.
(3) Require removal of the following animals
(A) Offspring of positives regardless of genotype
(B) Suspects - i.e., animals showing clinical signs or that
are positive on an unofficial test
(C) Scrapie positive animals
(D) Female goats
(E) QQ sheep unless exempted and maintained as described in
paragraph (4)(E) of this subsection
(4) Cleanup options
(A) Full flock depopulation - they must either do full genotype
plan or take full depopulation, we will allow them to pick and choose QR and
RR sheep to keep.
(B) Genotype the flock.
(C) Retain RRs only. (There was some concern about paying indemnity
for QR animals.) Require an enhanced basis PEMMP which would be reviewed annually.
(D) Retain RRs and QRs. Follow with enchanted basic PEMMP.
(E) Retain RRs, QRs and some QQs under the following conditions:
(i) All QQ sheep are quarantined to premise or move by VS 1-27
to slaughter only and arrangements must be made for them to be sampled for
testing at slaughter, culling or death.
(ii) Keep QQ sheep only if they have negative third eyelid
tests (APHIS pays for one test on each QQ sheep, owner is responsible for
additional tests).
(iii) Full PEMMP as defined in 9 CFR plus the requirements
listed here for 5 years after the last positive animal is removed or until
all of the original QQs have been removed which ever is longer.
(iv) Use double tested RR bucks on entire flock i.e. male animals
must be castrated, removed to another premises or tested twice as RR before
they reach sexual maturity. Owner could use a QR ram but would be required
to genotype the offspring, the first year APHIS would pay for testing, subsequent
years would be at owners' expense. (This will allow producers additional time
to find a RR ram.)
(v) QQ sheep will be identified with two forms of ID, one of
which will be an official ear tag or APHIS assigned tattoo in the case of
animals that can not retain an ear tag.
(vi) QR, HR, or RR genotype of animals sold for breeding purposes
must be documented using an official ID and test document or retested at owners'
expense prior to sale.
(vii) The DSEs determination, based on low scrapie prevalence
in flock and adequate management and facilities, that theses retained animals
poses a minimal risk.
(viii) Establish separate flock with separate equipment for
QQ animals.
(ix) Require proper lambing hygiene.
(c) High-risk animals in other flocks that have been traced
out of source or infected flocks will be placed under quarantine until depopulated
and tested or the Designated Scrapie Epidemiologist makes another determination.
(d) Exposed animals will be placed under hold order and a post-exposure
management and a monitoring plan formulated. The Designated Scrapie Epidemiologist
will determine the final disposition of the animals.
