(a)Official [Equine Piroplasmosis] Test. [
:] A complement fixation test (CFT) or competitive enzyme
linked immunosorbent assay (cELISA) are the official tests for equine
piroplasmosis. [A test for Equine Piroplasmosis applied
and reported by a laboratory approved by the Commission. The sample
must be collected by or under the direct supervision of an authorized
veterinarian. A completed Equine Piroplasmosis Laboratory Test chart
(Form 10-07) must be submitted with the sample, listing the description
of the equine to include the following: age, breed, color, sex, animal's
name, and all distinctive markings (i.e., color patterns, brands,
tattoos, scars, or blemishes), and any RFID numbers applied to the
equine. In the absence of any distinctive color markings or any form
of visible permanent identification (brands, tattoos or scars), the
equine must be identified by indicating the location of all hair whorls,
vortices or cowlicks with an "X" on the illustration provided on the
chart. In lieu of the manual illustration, digital photographs clearly
showing the equine from the left side, right side, and full face may
be incorporated in the chart. All charts must list owner's name, address,
the equine's home premises and county, the name and address of the
authorized individual collecting the test sample, and laboratory and
individual conducting the test. The Piroplasmosis test document shall
list one equine only.]
(b)Authorization to conduct test.
Only a test applied and reported by a laboratory approved by the commission
will be considered an official test. Only samples collected by or
under the direct supervision of an authorized veterinarian accompanied
by a completed Equine Piroplasmosis Laboratory Test chart (form 10-07)
will be accepted for official testing.
(c)[(b)] Reactor. A reactor
is any equine which discloses a positive reaction to the official
test [for Piroplasmosis on a Complement Fixation (CF) or
competitive Enzyme Linked Immunosorbent Assay (cELISA) applied at
a laboratory approved by the Commission]. The individual collecting
the test sample must notify the equine's owner of the quarantine within
48 hours after receiving the results. Movement of all piroplasmosis [
Piroplasmosis] positive equine and all equine epidemiologically
determined to have been exposed to a piroplasmosis [Piroplasmosis
] positive equine will be restricted. Retests of a reactor may
only be performed by a representative of the commission [
Commission].
(d)[(c)] Official identification
of reactors [Identification of Reactors].
(1)A reactor must be identified with an implanted
radio frequency microchip identification device that provides unique
identification for each individual equine and complies with ISO 11784/11785
and one of the following methods as determined by the commission [
Commission]:
(A)The reactor [equine] may be identified
with a [permanent mark as described herein or as approved by
the Commission. If] branded [the] letter "P" [will
be] applied as a hot-iron brand, freeze-marking brand, [
or a] hoof brand, or as approved by the commission.
For a freeze [Freeze] or hot-iron [
Hot-Iron] brand, the "P" brand must be not less than
two inches high and shall be applied to the left shoulder or left
side of the neck of the reactor. For a hoof brand, the
"P" brand must be applied to the front left hoof and reapplied as
necessary to maintain visibility;
(B)Using an identification device or a unique tattoo,
approved by the commission [Commission], that
provides unique identification for each individual equine; or
(C)Using digital photographs sufficient to identify
the individual equine.
(2)Reactors must be identified by an authorized veterinarian
or representative of the commission [Commission]
within 10 [ten] days of the date the laboratory
completes the test unless the equine is destroyed [equine
being classified as a reactor by the Commission]. Any equine
destroyed prior to identification must be described in a written statement
by the authorized veterinarian or other authorized personnel certifying
to the destruction. [The description must be sufficient to identify
the individual equine including, but not limited to, name, age, breed,
color, gender, distinctive markings, and unique and permanent forms
of identification when present (e.g., brands, tattoos, scars, cowlicks,
blemishes or biometric measurements).] This certification must
be submitted to the commission [Commission]
within 10 [ten] days of the date the equine
is destroyed.
(d)Any equine [Equine] entering
a racetrack facility, with the exception of thoroughbreds, must
have a negative piroplasmosis [Piroplasmosis]
test [(Theileria equi)] within the past 12 months. A racetrack
facility is grounds used to conduct live horse racing events and is
not limited to facilities licensed by the Texas Racing Commission.
The agency certifies that legal counsel has reviewed
the proposal and found it to be within the state agency's legal authority
to adopt.
