9 CFR Part 71
[Docket No. 97-099-2]
EIA; Handling Reactors at Livestock Markets
AGENCY: Animal and Plant Health Inspection Service, USDA.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are amending the regulations pertaining to livestock
facilities under State or Federal veterinary supervision to require
that any livestock facility accepting horses classified as reactors to
equine infectious anemia must quarantine these animals at all times at
least 200 yards from all equines that are not reactors to this disease.
Currently, livestock facilities accepting reactors to equine infectious
anemia are required to quarantine the reactors that will remain at the
facility for longer than 24 hours at least 200 yards away from all
other animals. This rule will help to prevent the interstate spread of
equine infectious anemia, a contagious, vector-borne disease affecting
equines.
EFFECTIVE DATE: July 13, 1998.

SUPPLEMENTARY INFORMATION:
Background
The regulations in subchapter C, ``Interstate Transportation of
Animals (Including Poultry) and Animal Products,'' of chapter I, title
9, of the Code of Federal Regulations contain provisions designed by
the Animal and Plant Health Inspection Service (APHIS) to prevent the
dissemination of animal diseases in the United States. Part 71 of
subchapter C includes general provisions. Section 71.20 pertains to
APHIS approval of livestock facilities, which include stockyards,
livestock markets, buying stations, concentration points, or any other
premises under State or Federal veterinary supervision where livestock
are assembled. Section 71.20(a) includes an agreement that livestock
facilities must execute to obtain APHIS approval. According to the
agreement, any approved livestock facility that elects to accept horses
that are reactors to equine infectious anemia (EIA) must place EIA
reactors in a quarantine pen at least 200 yards from any non-EIA-
reactor horses and other animals, unless the EIA reactors will be
moving out of the facility within 24 hours of arrival. (According to
the definitions in Sec. 71.1, ``horses'' includes ``horses, asses,
mules, ponies, and zebras.'' Throughout this document, the same
definition applies.)
EIA is a contagious, potentially fatal disease affecting horses
that is spread by infected blood coming into contact with the blood in
a healthy animal. Therefore, humans can spread EIA from horse to horse
through unsafe vaccination or blood-testing practices; naturally, the
disease is spread by insect vectors. Although, theoretically, EIA could
be spread by any type of blood-consuming insect, such as mosquitoes and
deer flies, the disease is generally spread by large horse flies. EIA
spreads when a blood-consuming insect is interrupted during a feeding
on an infected animal and then resumes feeding on an uninfected animal
while the infected blood is still on the insect's mouthparts. While
mosquitoes have finely structured mouthparts that directly penetrate
small blood vessels, the mouthparts of horse flies and deer flies
include scissorlike blades that cut and slash the horse's skin leaving
relatively large amounts of blood on the mouthparts. Research has shown
that deer flies and smaller species of horse flies are not as easily
disrupted from their bloodmeals on horses as are large horse flies. The
large flies cause painful bites that trigger a physiological response
from the horse. If disrupted by the horse while feeding, the horse fly
may then move to another horse to complete the bloodmeal.1

Regulations pertaining to the interstate movement of animals
affected with EIA are located in 9 CFR part 75. According to these
regulations, EIA reactors may be moved interstate only for immediate
slaughter, to a diagnostic or research facility, to the animal's home
farm, or to an approved stockyard for sale for immediate slaughter.
Approximately 1,500 horses in the United States test positive for EIA
each year. Currently, an estimated 40 percent of these animals move
through livestock markets on their way to slaughter.
On January 27, 1998, we published in the Federal Register (63 FR
3849-3851, Docket No. 97-099-1) a proposal to amend the regulations at
Sec. 71.20(a). Because EIA is transmitted by horse flies that feed on
the blood of horses, allowing healthy horses to come into close contact
with EIA reactors for any length of time could allow for infection of
the healthy horses. Therefore, we proposed to remove the exemption from
the quarantine requirement for EIA reactors that will be in an approved
livestock facility for fewer than 24 hours. We also proposed to remove
the requirement that EIA reactors be quarantined at least 200 yards
away from nonequine animals because we no longer believe this
requirement is necessary to prevent EIA transmission.
We solicited comments concerning our proposal for 60 days ending
March 30, 1998. We received six comments by that date. They were from
representatives of State departments of agriculture, organizations
representing the veterinary profession, an equine industry association,
and an organization that represents livestock auction markets and
livestock dealers. Five of the comments supported the proposed rule as
written. These commenters generally stated that the proposed rule would
help to prevent the interstate spread of EIA and that APHIS should
implement the proposed rule to help protect healthy horses from this
disease. The concerns expressed by the one commenter not in favor of
the proposed rule are discussed below.
The commenter stated that perhaps effective alternatives to the
200-yard separation requirement exist that were not considered by
APHIS. The commenter raised questions about other control measures,
such as using covered facilities to separate reactors and nonreactors,
reducing the 200-yard separation requirement for horses not showing
clinical signs of EIA, and using insecticide sprays to control the
vector that transmits EIA. The commenter requested that the proposed
rule be substantially altered or withdrawn for further consideration
``because much more information is needed on effective, practical
control measures in the movement of EIA reactors through livestock
markets.''
We disagree that such information is lacking. Separating EIA
reactors from healthy horses by a distance of 200 yards is a
scientifically proven and time-tested method of preventing EIA
transmission by insect vector. This prevention measure is absolute;
covered facilities and pesticides are only partial control measures. In
regard to the suggestion to reduce the 200-yard separation requirement
for horses not showing clinical signs of EIA, horses that are
asymptomatic reactors are capable of spreading the disease.
The commenter also expressed concerns regarding two economic
issues. The first was that markets with extremely limited land area
will not be able to meet the 200-yard separation requirement and that
this situation could have two effects: The number of livestock markets
available to owners of EIA reactors would be limited, and livestock
markets that cannot comply with the rule and that are near slaughter
facilities will lose trade in EIA reactors to the slaughter facilities.
The second concern was that this rule would give an unfair economic
advantage to entities that compete with livestock markets because this
rule would apply only to livestock markets and not other types of
related businesses, such as independent buying stations.
In regard to the first concern, we believe that there are few
livestock facilities that cannot comply with this rule because of a
lack of adequate land area. Further, the effect of this rule on all
livestock markets will be minimal. The number of EIA reactors moving
through livestock markets annually is extremely small compared to the
number of healthy horses and all other livestock combined that move
through these markets. During the last decade, an average of 1,500 EIA
reactors have been identified annually. We estimate that fewer than
half of these animals are sent to slaughter. The business derived from
the sale of EIA reactors to livestock markets is an extremely small
percentage of the total business derived from the sale of all other
U.S. livestock to these facilities.
In regard to the issue of this rule not applying to entities that
compete with livestock markets, APHIS does not
[[Page 32119]]
regulate intrastate movement of horses unless an extraordinary
emergency is declared. Therefore, EIA reactors sold intrastate are
normally outside of our jurisdiction. However, any facility that deals
in EIA reactors sold interstate must be approved by APHIS and abide by
this rule.
Therefore, based on the rationale set forth in the proposed rule
and in this document, we are adopting the provisions of the proposal as
a final rule without change.
Executive Order 12866 and Regulatory Flexibility Act
This rule has been reviewed under Executive Order 12866. The rule
has been determined to be not significant for the purposes of Executive
Order 12866 and, therefore, has not been reviewed by the Office of
Management and Budget.
The regulations in 9 CFR part 71 require that any horses classified
as EIA reactors and accepted by a facility for sale are to be placed in
quarantine pens at least 200 yards from all non-EIA-reactor horses or
other animals, unless moving out of the facility within 24 hours of
arrival. This rule removes the ``less-than-24-hours'' exemption:
Quarantine will be required regardless of the length of time between an
EIA reactor's arrival and departure from a facility. This rule also
amends the regulations by requiring that EIA reactors be quarantined at
least 200 yards away from all horses that are not reactors, rather than
at least 200 yards away from all other animals.
Facilities that buy and sell horses are included in the Small
Business Administration's SIC (Standard Industrial Classification)
category ``Livestock Services, Except Veterinary.'' Firms in this
category with annual receipts of less than $5 million are considered
small entities. It is likely that most, if not all, of the
approximately 200 facilities that buy and sell horses are ``small''
under this definition.
Most facilities that buy and sell horses already have quarantine
pens, in accordance with current regulations. The estimated 20 percent
that do not have quarantine pens could build or modify existing pens
for quarantine use at a relatively minor cost: APHIS estimates that, at
most, construction of a quarantine pen would cost about $1,000.
However, costs of quarantine pen construction are not attributable
to this rule because quarantine, per se, is not a new requirement. Only
those facilities that accept EIA reactors and that in the past have
always moved all EIA reactors within 24 hours of arrival would need to
construct or modify pens for quarantine purposes as a consequence of
this rule. As no facility can always be certain of movement of EIA
reactors within 24 hours, no costs should be incurred strictly because
of this rule. Moreover, by requiring all EIA reactors at approved
livestock facilities to be quarantined, the horse industry in general
will benefit from a further reduction in the risk of EIA transmission.
Under these circumstances, the Administrator of the Animal and
Plant Health Inspection Service has determined that this action will
not have a significant economic impact on a substantial number of small
entities.
