[Docket No. 96-013-1]


Official Pseudorabies Tests

AGENCY: Animal and Plant Health Inspection Service, USDA.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: We are proposing to amend the pseudorabies regulations by 
adding the glycoprotein I Particle Concentration Fluorescence 
Immunoassay test to the list of official pseudorabies tests and allow 
its use as an approved differential test. We are proposing to take this 
action based on a finding that the sensitivity and specificity of the 
glycoprotein I Particle Concentration Fluorescence Immunoassay test are 
equivalent to those of official tests for the diagnosis of 
pseudorabies. This proposed change would allow the glycoprotein I 
Particle Concentration Fluorescence Immunoassay test to be used as an 
official pseudorabies test to qualify certain pseudorabies vaccinated 
swine for interstate movement to destinations other than slaughter or a 
quarantined herd or quarantined feedlot. Adding the glycoprotein I 
Particle Concentration Fluorescence Immunoassay test to the list of 
official pseudorabies tests would also allow its use for the testing of 
nonvaccinated swine.

DATES: Consideration will be given only to comments received on or 
before February 13, 1998.

ADDRESSES: Please send an original and three copies of your comments to 
Docket No. 96-013-1, Regulatory Analysis and Development, PPD, APHIS,

SUPPLEMENTARY INFORMATION:

Background

    Pseudorabies is a contagious, infectious, and communicable disease 
of livestock, primarily swine, and other animals. The disease, also 
known as Aujeszky's disease, mad itch, and infectious bulbar paralysis, 
is caused by a herpes virus. The Animal and Plant Health Inspection 
Service's (APHIS') regulations in 9 CFR part 85 (referred to below as 
the regulations) govern the interstate movement of swine and other 
livestock (cattle, sheep, and goats) in order to help prevent the 
spread of pseudorabies.
    For the purposes of interstate movement, the regulations separate 
swine into four basic categories: (1) Swine infected with or exposed to 
pseudorabies; (2) pseudorabies vaccinated swine (except swine from 
qualified negative gene-altered vaccinated herds) not known to be 
infected with or exposed to pseudorabies; (3) swine not vaccinated for 
pseudorabies and not known to be infected with or exposed to 
pseudorabies; and (4) swine from qualified negative gene-altered 
vaccinated herds. Provisions governing the interstate movement of swine 
from each category are found in Secs. 85.5, 85.6, 85.7, and 85.8, 
respectively.
    Paragraphs (a) and (b) of Sec. 85.6 provide that pseudorabies 
vaccinate swine, except swine from qualified negative gene-altered 
vaccinated herds, that are not known to be infected with or exposed to 
pseudorabies may be moved interstate directly to slaughter or to a 
quarantined herd or quarantined feedlot under certain specified 
conditions. Paragraph (c) of Sec. 85.6 further provides that such 
pseudorabies vaccinate swine may be moved interstate to destinations 
other than slaughter or a quarantined herd or quarantined feedlot if 
the swine have been vaccinated for pseudorabies with a glycoprotein I 
(gpI) deleted gene-altered pseudorabies vaccine and they are 
accompanied by a certificate that is delivered to the consignee. The 
regulations in Sec. 85.6(c) also require that the certificate contain 
certain additional information, specifically: (1) The identification of 
each swine; (2) a statement that each swine was vaccinated with a gpI 
deleted gene-altered pseudorabies vaccine; (3) a statement that each 
swine has been subjected to an approved differential pseudorabies test 
no more than 30 days prior to the interstate movement and has been 
found negative; (4) the date of the approved differential pseudorabies 
tests; and (5) the name of the laboratory that conducted the approved 
differential pseudorabies test. Currently, the regulations provide only 
for the use of the gpI enzyme-linked immunosorbent assay (ELISA) as an 
approved differential pseudorabies test to qualify swine for interstate 
movement under Sec. 85.6(c).
    The Committee on Diagnostics and Interpretive Serology of the 
American Association of Veterinary Laboratory Diagnosticians (AAVLD) 
has recognized that the sensitivity and specificity of the gpI Particle 
Concentration Fluorescence Immunoassay (PCFIA) test are equivalent to 
those of official tests for the diagnosis of pseudorabies. Based on 
that finding, we are proposing to add the gpI PCFIA test to the list of 
official pseudorabies tests in Sec. 85.1 and allow its use as an 
approved differential pseudorabies test to qualify swine for interstate 
movement under Sec. 85.6(c).
    Adding the gpI PCFIA test as an official pseudorabies test would 
also mean that the gpI PCFIA test would be available for testing 
nonvaccinated swine to determine their pseudorabies status. As noted 
above, the AAVLD has recognized that the sensitivity and specificity of 
the gpI PCFIA test are equivalent to those of official tests for the 
diagnosis for pseudorabies. The gpI PCFIA test is specific for 
antibodies to the glycoprotein I present in the pseudorabies virus; 
nonvaccinated swine, as well as swine vaccinated with a gpI-deleted 
vaccine, would not produce positive results to the gpI PCFIA test 
unless the swine were infected with pseudorabies. Designating the gpI 
PCFIA test as an official pseudorabies test would enable swine

[[Page 65631]]

producers to use a single test on both gpI vaccinates and nonvaccinated 
swine.

Executive Order 12866 and Regulatory Flexibility Act

    This proposed rule has been reviewed under Executive Order 12866. 
For this action, the Office of Management and Budget has waived its 
review process required by Executive Order 12866.
    This proposed rule would amend the pseudorabies regulations by 
adding the gpI PCFIA test to the list of official pseudorabies tests. 
This proposed change would allow the gpI PCFIA test to be used as an 
official pseudorabies test to qualify certain pseudorabies vaccinated 
swine for interstate movement to destinations other than slaughter or a 
quarantined herd or quarantined feedlot. Adding the gpI PCFIA test to 
the list of official pseudorabies tests would also allow its use for 
the testing on nonvaccinated swine.
    The total U.S. inventory of hogs and pigs was approximately 56 
million, valued at $5.283 billion, in 1996. The gross income of the 
inventory is approximately $11 billion. More than 99 percent of swine 
producers are considered to be small entities. According to the 
standard set by the Small Business Administration for agricultural 
producers, a producer with less than $0.5 million annually in sales 
qualifies as a small entity.
    Nearly 95 percent of the swine inventory within the United States 
has not yet achieved pseudorabies-free status. The addition of this new 
test would provide an extra choice of official pseudorabies test for 
those who raise swine, when a test is required for interstate movement. 
Testing costs would be incurred only when an owner chose to move gpI 
vaccinates interstate to destinations other than slaughter or a 
quarantined herd or quarantined feedlot, since pseudorabies vaccinated 
swine do not require a test prior to interstate movement for slaughter 
or to a quarantined herd or quarantined feedlot. The cost of the gpI 
PCFIA test is within the range of the currently available tests. The 
test is highly automated and those laboratories that have the test kit 
would be expected to accomplish the testing on large numbers of samples 
with greater speed. The test results have been found to produce fewer 
false negatives, reducing the need for tracebacks. The positive effect 
of having accurate results in a short time would be beneficial in all 
stages of pseudorabies eradication.
    The provisions of this proposed rule that would allow the use of 
the gpI PCFIA test to determine the pseudorabies status of 
nonvaccinated swine are not expected to have a significant economic 
impact on the owners of nonvaccinated swine, as it only introduces an 
additional pseudorabies testing tool to ensure the health of the U.S. 
swine population. It is likely, though, that since the new gpI PCFIA 
test may be slightly higher in cost than other testing tools that are 
on the market, most owners of nonvaccinated swine would continue using 
less expensive official pseudorabies test until the cost of the gpI 
PCFIA test became comparable to that of other official tests.
    Under these circumstances, the Administrator of the Animal and 
Plant Health Inspection Service has determined that this action would 
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 12988

    This proposed rule has been reviewed under Executive Order 12988, 
Civil Justice Reform. If this proposed rule is adopted: (1) All State 
and local laws and regulations that are in conflict with this rule will 
be preempted; (2) no retroactive effect will be given to this rule; and 
(3) administrative proceedings will not be required before parties may 
file suit in court challenging this rule.

Paperwork Reduction Act

    This proposed rule contains no new information collection or 
recordkeeping requirements under the Paperwork Reduction Act of 1995 
(44 U.S.C. 3501 et seq.).
