Current through Register Vol. 48, No. 38, September 20, 2024
a) The
following definitions shall be applicable to this Section:
"Accredited laboratory" means a laboratory operated by the
Illinois Department of Agriculture or the University of Illinois College of
Veterinary Medicine, or a laboratory approved by the Director (on the basis
that it is using USDA approved methods).
"Herd" or "premises" means all animals under common ownership
or supervision on a specific geographic area. The herd or premises is defined
by the owner and veterinarian, and may include all or a portion of pork
production under their control. A premises describes a physical space that is
dedicated for use by the producer when entering the PRRS monitored herd
program. For an entire production system to be monitored, all phases of
production must be sampled and participate in the program. Producers can select
the production group they wish to monitor. All phases of production up to and
including the "selected" group must participate in the program. If multiple
locations input swine into the proposed PRRS monitored production herd or
premises, all sites must be sampled separately to validate the final PRRS
monitoring herd defined premises.
"PRRS" means porcine reproductive and respiratory
syndrome.
b) Criteria for
herd to enter into or to remain in the voluntary monitoring herd program:
1) Participation in this program is voluntary
and the producer/owner is responsible for the cost of testing.
2) All breeding swine that have been tested
must have permanent identification such as registry association approved
individual tattoo, ear notch, registration number or approved ear tags.
"Approved ear tags" means any ear tag that is tamper resistant and has been
approved for use by the USDA. Information concerning manufacturers of approved
ear tags may be obtained from the Department.
3) The owner annually signs a producer
agreement form verifying that the producer or manager:
A) understands the clinical signs of
PRRS;
B) identifies a herd
veterinarian;
C) agrees to work
with that veterinarian in the event clinical signs of PRRS develop;
D) identifies the premises and animal
production groups that will be monitored and the average number of animals per
premises or production group; and
E) outlines the testing procedure employed to
verify PRRS testing qualifications.
4) Quarter sample size for initial monitoring
for all production systems and for monitoring phase for farrow-weaning sites

Upon completion of the four qualifying tests, the Director shall issue a
certificate of PRRS monitoring for the herd. A new certificate will be issued
annually upon completion of the required monitoring test and the receipt of the
annual producer agreement form.
c) Procedure for monitoring farrow-finish and
seedstock producer herds:
1) Initial herd
monitoring:
A) Test the required number of
swine (Table A) in the grow-finisher herd at 90-day intervals (+ or - 15 days)
for a period of 12 months (4 tests total).
B) Blood test the required number of breeding
stock (Table A) at 90-day intervals (+ or - 15 days) for a period of 12 months
(4 tests total). No sow shall be sampled twice with 101 sows or more in the
breeding herd. Individual identification is required.
C) External additions must be held in
isolation and either tested prior to or within 10 days after arrival and
identified and tested 40-60 days after arrival. Only after the retest can the
animal be released from isolation. If a positive animal is detected, all
co-mingled animals must be retested 30-40 days after the positive is disclosed.
Any PRRS positive animal must be promptly removed from the monitored
premises.
D) All internal
replacements (gilts, boars, teaser boars) must be PRRS test negative prior to
entry into the breeding herd.
2) Maintenance of monitored herd status:
A) Test animals in the grow-finisher
according to Table B on 90-day intervals (+ or - 15 days). Pigs must weigh at
least 90 pounds.
B) Test breeding
herd according to Table B on 90-day intervals (+ or - 15 days). Sows must be of
all parities and from each production phase (gestation, post-weaning,
lactation, and off-premises gestation). Individual identification is
required.
C) Additions to the herd
shall be as prescribed in subsection (c)(1)(C).
d) Procedure for monitoring farrow-feeder pig
premises:
1) Initial herd monitoring:
A) Test the required number of feeder pigs
(Table A) at 90-day intervals (+ or - 15 days) for a period of 12 months (4
tests). The sample should represent the oldest pigs in the nursery. Pigs must
be present in the nursery at least two weeks prior to the sampling to be
eligible for testing. No identification is required. Multiple pens and litters
must be sampled.
B) Test the
required number of breeding swine (Table A) at 90-day intervals (+ or - 15
days) for a period of 12 months (4 tests). No sow will be sampled twice in
herds of 101 or more sows during the year. Individual identification is
required.
C) External additions
must be held in isolation and either tested prior to or within 10 days after
arrival and identified and tested 40-60 days after arrival. Only after the test
can the animal be released from isolation. If a positive animal is detected,
all in-contact animals must be retested 30-40 days after the positive is
disclosed. Any PRRS positive animal must be promptly removed from the monitored
premises.
D) All internal
replacements (gilts, boars, teaser boars) must be PRRS test negative prior to
entry into the breeding herd.
2) Maintenance of monitored herd status:
A) Test the feeder pigs according to Table B
on 90-day intervals (+ or - 15 days). The sample should represent the oldest
pigs in the nursery. Pigs must be present in the nursery at least two weeks
prior to the sampling to be eligible for testing. No identification is
required. Multiple pens and litters must be sampled.
B) Test breeding herd according to Table B on
90-day intervals (+ or - 15 days). Sows must be of all parities and from each
production phase (gestation, post-weaning, lactation, and off-premises
gestation). Individual identification is required.
C) Additions to the herd shall be as
prescribed in subsection (d)(1)(C).
e) Procedure for monitoring farrow-weaning
pig premises:
1) Initial herd monitoring:
A) No piglet sampling is required.
B) Test the required number of breeding swine
(Table A) at 90-day intervals (+ or - 15 days) for a period of 12 months (4
tests). No sow will be sampled twice in herds of 101 or more sows during the
year. Individual identification is required.
C) External additions must be held in
isolation and either tested prior to or within 10 days after arrival and
identified and tested 40-60 days after arrival. Only after the retest can the
animal be released from isolation. If a positive animal is detected, all
in-contact animals must be retested 30-40 days after the positive is disclosed.
Any PRRS positive animal must be promptly removed from the monitored
premises.
D) All internal
replacements (gilts, boars, teaser boars) must be PRRS test negative prior to
entry into the breeding herd.
2) Maintenance of monitored herd status:
A) No piglet sampling is required.
B) Test breeding herd according to Table B on
90-day intervals (+ or - 15 days). Sows must be of all parities and from each
production phase (gestation, post-weaning, lactation and off-premises
gestation). Individual identification is required.
C) Additions to the herd shall be as
prescribed in subsection (e)(1)(C).
f) Procedure for monitoring boar stud
premises where only seronegative boars can reside:
1) Initial herd monitoring:
A) All boars must be tested every six months
(+ or - 15 days) for a period of 12 months (two tests).
B) All incoming boars must be tested prior to
arrival or within 10 days after arrival and again 40-60 days after arrival.
Boars must originate from a farm where there has been no evidence of PRRS for
at least one year. The herd of origin must not be using PRRS vaccine.
2) Maintenance of monitored herd
status:
A) Test the required number of boars
(Table B) every 90 days (+ or - 15 days).
B) All incoming boars must be tested prior to
arrival or within 10 days after arrival and again 40-60 days after arrival.
Boars must originate from a farm where there has been no evidence of PRRS for
at least one year. The herd of origin must not be using PRRS vaccine.
g) Suspension or
revocation of monitored herd status:
1) If a
positive animal is detected during a monitoring test, the monitored herd status
shall be suspended until all in-contact animals have been retested 30-40 days
after the positive is disclosed. Any PRRS positive animals must be promptly
removed from the monitored premises. If subsequent positives are revealed, the
monitored herd status shall be revoked.
2) Failure to conduct the required testing
shall result in the revocation of the monitored herd status.
