| (6) The movement restrictions will be released as provided
for in this section utilizing an approved test that will identify
vaccine titers.
(g) Qualified pseudorabies negative herd.
(1) Qualified pseudorabies negative herd status is
attained by 100% testing of the adult breeding herd over six months
of age plus a number of progeny equal to 20% of the breeding swine
population in the herd and finding them negative to an official pseudorabies
serologic test. Progeny shall be randomly selected from the oldest
swine in the herd less than six months of age. The herd must not have
been a known infected herd within the past 30 days. A minimum of 90%
of the swine in the herd must have been on the premises and part of
the herd for at least 90 days prior to the qualifying official pseudorabies
serologic test or have entered directly from another qualified pseudorabies
negative herd.
(2) Qualified pseudorabies negative herd status is
maintained by conducting an official pseudorabies serologic test at
least once each year on at least 80% of the swine over six months
of age and on a number of progeny equal to 20% of the breeding swine
population of the herd. All swine tested shall be randomly selected
and in the case of adult swine, representative of all age groups on
the premises. This must be accomplished by testing 25% of the required
breeding swine and progeny every 80 to 105 days and finding all swine
so tested negative, or by testing 10% of the required breeding swine
and progeny each month and finding all swine so tested negative. No
swine shall be tested twice in one year to comply with the 25% requirement
or twice in 10 months to comply with the 10% requirement.
(3) If on a qualifying official pseudorabies serologic
test or any subsequent official pseudorabies test, any swine are tested
positive, qualified pseudorabies negative herd status is suspended
until the infection status of the herd is determined through testing
and an epidemiological study of the herd. Before qualified pseudorabies
negative herd status may be attained or regained, all seropositive
swine must be sold for slaughter and the herd tested and released
from movement restrictions as provided for in subsections (e) and
(g) of this section.
(4) All swine intended to be added to a qualified pseudorabies
negative herd shall be isolated until the swine are tested negative
on two official pseudorabies serologic tests, one conducted 30 days
or more after the swine have been placed in isolation and the second
conducted 30 days or more after the first test, unless any of the
following exceptions apply:
(A) Swine intended to be added to a qualified pseudorabies
negative herd directly from another qualified pseudorabies negative
herd may be added without isolation or testing;
(B) Swine intended to be added to a qualified pseudorabies
negative herd from another qualified pseudorabies negative herd, but
with interim contact with swine other than those from a single qualified
pseudorabies negative herd, shall be isolated until the swine have
been found negative to an official pseudorabies serologic test, conducted
30 days or more after the swine have been placed in isolation; or
(C) Swine returned to the herd after contact with swine
other than those from a single qualified pseudorabies negative herd
shall be isolated until the swine have been found negative to an official
pseudorabies serologic test conducted 30 days or more after the swine
have been placed in isolation.
(5) Test records will be maintained by the commission
at its Central Office. Herd owners or caretakers will receive a letter
from the Executive Director's designee listing test dates, test results,
the laboratory in which the test was run, and the qualified herd status
of the herd.
(h) Requirements for a pseudorabies-monitored feeder-pig
herd. To qualify as a pseudorabies-monitored feeder-pig herd, breeding
swine must sample and test negative to an official pseudorabies serologic
test during the last 12 months at the following rate:
(1) 10 head--test all;
(2) 11 to 35 head--test 10;
(3) 36 head or more--test 30% or 30, whichever is less.
Breeding swine that are tested are to be selected at random from all
age groups, including herd boars, with all groups to be proportionately
represented.
(i) Requirements for continuous flow feeder facilities
in which there are no breeding animals on the premises. When provisions
of the State-Federal-Industry Program Standards for Pseudorabies Eradication
require surveillance testing of these feeder facilities for advancement
of the state to the next stage of the eradication program, one of
the following methods will be used to satisfy this requirement.
(1) Collection of blood from a random sample of swine
in the feeder facility in the following representation:
(A) less than 100 head in the feeder facility--test
25;
(B) 100-200 head--test 27;
(C) 201-999 head--test 28;
(D) 1,000 head and over--test 29.
(2) Collection of blood from swine consigned from a
feeder facility at slaughter using the criteria shown in paragraph
(1) of this subsection, to determine the number of swine to be tested.
(j) Owner assistance. If ordered by the commission
or its representative, the owner or caretaker of swine shall submit
the swine and furnish labor and facilities used in normal operation
in order that the swine may be tested, vaccinated, or otherwise handled
in accordance with this chapter.
