equine diseases being added to the reportable list. Texas equine
producers, veterinarians and livestock health officials have be-
come increasingly concerned about Equine Viral Arteritis (EVA),
which has recently been detected in New Mexico and Utah this
year.
EVA is an infectious viral disease of horses that causes a variety
of clinical symptoms, most significantly abortions. The disease
is transmitted through both the respiratory and reproductive sys-
tems. Many horses are either asymptomatic or exhibit flu-like
symptoms for a short period of time. An abortion in pregnant
mares is often the first, and in some cases, the only sign of the
disease. EVA has been confirmed in a variety of horse breeds,
with the highest infection rate found in adult Standardbreds.
Breeders, racehorse owners, and show horse owners all have
strong economic reasons to prevent and control this disease.
While it does not kill mature horses, EVA can eliminate an en-
tire breeding season by causing numerous mares to abort. In
addition, U.S. horses that test positive for EVA antibodies and
horse semen from EVA-infected horses can be barred from en-
tering foreign countries. While some infected equine exhibit no
signs of disease, owners should be alert and notify their accred-
ited private veterinary practitioner if horses or foals develop signs
of EVA, including fever, depression, diarrhea, coughing or nasal
discharge, or swelling of the legs, body or head. Laboratory test-
ing is necessary to confirm a diagnosis, as other equine diseases
can present similar clinical signs.
Equine Herpes Virus-1 (EHV-1) is the second disease that has
given Texas equine producers concern. EHV-1 is attributed to
outbreaks of neurological disease in different venues across the
country and has rightfully captured our attention. The most re-
cent clinical case of neurologic EHV-1 in California involves a
horse from Golden Gate Fields. Raceways, horse shows, farms,
and clinics in several states have been noticeably impacted by
multiple cases of illness including several deaths.
Also House Bill (HB) 9 was passed by the 77th Texas Legislative
Session which added requirements related to duty of a veterinary
diagnostic laboratory or a person having care, custody, or con-
trol of an animal to report specified animal health diseases. This
requirement amends the Texas Agriculture Code Chapter 161,
161.101. The section, prior to HB 9, required only a veterinar-
ian to report to the Commission the existence of any diseases
specified by the rule. We are adding that to the rule.
No comments were received regarding adoption of the amend-
ments.
STATUTORY AUTHORITY
The amendments are adopted under the Texas Agriculture
Code, Chapter 161, 161.041(a) and (b), and 161.046 which
authorizes the Commission to promulgate rules in accordance
with the Texas Agriculture Code. Section 161.101 provides that
the Commission may adopt rules that require a veterinarian,
a veterinary diagnostic laboratory, or a person having care,
custody, or control of an animal to report a disease not covered
by subsection (a) or (b) if the Commission determines that
action to be necessary for the protection of animal health in this
state. The Commission shall immediately deliver a copy of a
rule adopted under this subsection to the appropriate legislative
oversight committees. A rule adopted by the Commission under
this subsection expires on the first day after the last day of the
first regular legislative session that begins after adoption of the
rule unless the rule is continued in effect by act of the legislature.45.2. Duty To Report.
(a) A veterinarian, a veterinary diagnostic laboratory or a per-
son having care, custody, or control of an animal, shall report the ex-
istence of the following diseases among livestock, exotic livestock,
domestic fowl, or exotic fowl to the commission within 24 hours af-
ter diagnosis. The following listing includes diseases and conditions
that are Office International Des Epizooties List A Diseases, Foreign
Animal Diseases, National Program Diseases or Texas Animal Health
Commission Designated Diseases.

(b) In addition to reporting the existence of a disease under
subsection (a), the veterinarian shall also report to the commission in-
formation relating to:
(1) the species and number of animals involved;
(2) any clinical diagnosis or postmortem findings;
(3) any death losses;
(4) location; and
(5) owner.
This agency hereby certifies that the adoption has been reviewed
by legal counsel and found to be a valid exercise of the agency's
