9 CFR Part 78
[Docket No. 93-044-2]
Official Brucellosis Tests
AGENCY: Animal and Plant Health Inspection Service, USDA.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are amending the brucellosis regulations by adding the D-
Tec Brucella A test to the list of official tests for
determining the brucellosis disease status of test-eligible cattle and
bison. We are taking this action because the D-Tec Brucella A
test has exhibited a high degree of specificity in identifying Brucella
abortus antibodies. Adding the D-Tec Brucella A test to the
list of official tests for brucellosis in cattle and bison will help
prevent the spread of the disease by making available an additional
means by which animal health personnel may obtain timely and accurate
diagnoses of brucellosis.
EFFECTIVE DATE: March 30, 1994.

SUPPLEMENTARY INFORMATION:
Background
Brucellosis is an infectious disease of animals and humans caused
by bacteria of the genus Brucella. In its principal animal hosts--
cattle, bison, and swine--brucellosis is characterized by abortion and
impaired fertility. The regulations in 9 CFR part 78 (referred to below
as the regulations) govern the interstate movement of cattle, bison,
and swine in order to help prevent the spread of brucellosis.
Official brucellosis tests are used to determine the brucellosis
disease status of cattle, bison, and swine. The regulations stipulate
that certain cattle, bison, and swine must, among other requirements,
test negative to an official brucellosis test prior to interstate
movement. Official brucellosis tests are also used to determine
eligibility for indemnity payments for animals destroyed because of
brucellosis. In Sec. 78.1 of the regulations, the definition of
official test lists those tests that have been designated as official
tests for determining the brucellosis disease status of cattle, bison,
and swine.
On September 27, 1993, we published in the Federal Register (58 FR
50290-50291, Docket No. 93-044-1) a proposal to amend the regulations
by adding the D-Tec Brucella A test to the list of official
tests for determining the brucellosis disease status of test-eligible
cattle and bison.
We solicited comments concerning our proposal for a 30-day comment
period ending October 27, 1993. We received one comment by that date,
from a veterinary medical association. The commenter supported our
proposed rule.
Therefore, based on the rationale set forth in the proposed rule,
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 change will not add any costs for agricultural producers.
It will, however, benefit farmers and ranchers who, without access to
this or the other available diagnostic tests, quarantine or destroy
animals on the basis of ``false positive'' reactions to presumptive
tests. We estimate that between 200 and 300 animals are unnecessarily
slaughtered or quarantined each year after having falsely tested
positive on presumptive tests. These losses could be prevented by the
use of diagnostic tests. The addition of the D-Tec Brucella A
test as an official test will prevent losses to farmers and ranchers if
they opt to use it. While losses resulting from false positives affect
only a few farmers and ranchers each year, this rule could modestly
benefit all those entities that avail themselves of the D-Tec
Brucella A test.
This rule is expected to have a beneficial effect on the producer
of the D-Tec Brucella A test and a negligible negative impact
on the only other producer of diagnostic tests. Both producers are
small entities.
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.
Executive Order 12372
This program/activity is listed in the Catalog of Federal Domestic
Assistance under No. 10.025 and is subject to Executive Order 12372,
which requires intergovernmental consultation with State and local
officials. (See 7 CFR part 3015, subpart V.)
Executive Order 12778
This rule has been reviewed under Executive Order 12778, Civil
Justice Reform. This rule: (1) Preempts all State and local laws and
regulations that are in conflict with this rule; (2) has no retroactive
effect; and (3) does not require administrative proceedings before
parties may file suit in court challenging this rule.
Paperwork Reduction Act
This rule contains no information collection or recordkeeping
requirements under the Paperwork Reduction Act of 1980 (44 U.S.C. 3501
et seq.).
List of Subjects in 9 CFR Part 78
Animal diseases, Bison, Cattle, Hogs, Quarantine, Reporting and
recordkeeping requirements, Transportation.
Accordingly, 9 CFR part 78 is amended as follows:
PART 78--BRUCELLOSIS
1. The authority citation for part 78 continues to read as follows:
Authority: 21 U.S.C. 111-114a-1, 114g, 115, 117, 120, 121, 123-
126, 134b, 134f; 7 CFR 2.17, 2.51, and 371.2(d).
Subpart A--[Amended]
2. In Sec. 78.1, in the definition of official test, paragraph
(a)(11) is redesignated as (a)(12), and a new paragraph (a)(11) is
added to read as follows:
Sec. 78.1 Definitions.
* * * * *
Official test.
(a) * * *
(11) D-Tec Brucella A test. An automated serologic test
to determine the brucellosis disease status of test-eligible cattle and
bison when conducted according to instructions approved by APHIS. The
degree of reactivity is measured by the ratio of the average optical
density of the sample to that of the Negative Control (S/N) and is
expressed as Percent Inhibition (1-S/N) x 100. The brucellosis
disease status of the animals is classified according to the following
established criteria:
------------------------------------------------------------------------
Percent inhibition Classification
------------------------------------------------------------------------
Less than or equal to 40 percent.................... Negative.
Greater than 40 percent and less than or equal to 70 Suspect.
percent.
Greater than 70 percent............................. Reactor.
