On or after July 1, 1962, the Department may, after hearing
establish and maintain swine brucellosis control areas within the State wherein
the Department shall examine and test such swine for brucellosis as the
Director may specify and limit the movements of swine from herds found to be
infected with brucellosis to bring about the control and eradication of swine
brucellosis within such control ares. When a county has been established as a
swine brucellosis control area, the following shall apply:
(a) Definitions.
(1) "Premises" means any place where swine
have been or are kept.
(2) "Swine
or animal" means the domestic hog of the family Suidae.
(3) "Vaccine" means any vaccine produced by a
laboratory licensed by the United States Department of Agriculture or
California Department of Public Health for use in preventing and/or treatment
of brucellosis in animals.
(4)
"Swine brucellosis" means the disease of swine caused by "Brucella"
microorganisms.
(5) "Official
inspector" means an inspector in the employ of the United States Department of
Agriculture, State Department of Agriculture, or the County Veterinarian's
Office.
(6) "Accredited
veterinarian" means a veterinarian who is so designated by the United States
Department of Agriculture and the Department.
(7) A "herd test" means a swine brucellosis
test on all segregated breeding swine over six (6) months of age on a
premise.
(8) "Reactor" means any
swine that discloses a complete agglutination reaction in the blood titer
dilution of 1/100 or higher; and any swine in an infected herd or herd of
unknown status disclosing complete agglutination reaction in the blood titer
dilution of 1/25 or higher, or any swine disclosing a positive card test
reaction.
(9) "Infected herd" means
a herd that discloses one or more swine with a complete agglutination reaction
in the blood titer dilution of 1/100 or higher, or a positive reaction to the
brucellosis card test.
(10)
"Negative herd" means a herd that has been herd tested and discloses no animal
reacting to the brucellosis card test or revealing more than incomplete blood
titer dilutions of 1/100, or a herd in which at least ten (10) percent of the
breeding swine have been tested annually in the Market Swine Testing Program
for three consecutive years and no reactors disclosed.
(11) "Negative swine or animal" means an
animal from:
(A) A validated brucellosis-free
herd; or
(B) A herd with a negative
herd test within the previous 30 days unless otherwise classified by Department
officials; or
(C) A herd of unknown
or infected status and negative to the brucellosis card test, or disclosing
less than complete agglutination in the blood titer of
1/25 or
higher.
(12) "Market
Swine Testing Program" means the testing of breeding swine marketed for
slaughter.
(b) Tests.
Blood tests shall be conducted on swine that will qualify
herds as negative herds and "validated brucellosis-free herds" and control
areas as "validated brucellosis-free areas." When requested by an official
inspector, any owner of swine in a Swine Brucellosis Control Area shall confine
and restrain all swine on his premises for bleeding and failure to do so shall
be regarded as a violation of this section.
(1) Collection of Samples.
Blood samples shall be collected by accredited
veterinarians or official inspectors. Reports of bleeding shall be on forms
prescribed by the Department.
(2) Identification of Animals.
All breeding swine officially tested under this regulation
shall be identified by ear tag, or tattoo, or registration number, or other
means prescribed by the Department.
(3) Testing.
All tests conducted under this regulation shall be
conducted in laboratories of the Federal or State Departments of Agriculture,
University of California School of Veterinary Medicine, an approved County
Veterinarian's laboratory, or by such persons as may be authorized to conduct
the brucellosis card test.
(4) Infected Herds.
When a herd has been found to be infected, all breeding
swine in the herd shall be maintained under hold order in accordance with
Section 9565 of the Agricultural Code until the herd qualifies as negative in
accordance with one of the following plans or such other means specified by the
Department:
PLAN A. TO BE USED WHEN BRUCELLOSIS IS WELL ESTABLISHED IN
THE HERD
1. Market the entire infected
herd for slaughter under official supervision.
2. Clean and disinfect the swine houses and
equipment in accordance with (c) of this section. Such houses and premises are
to be kept free of swine for 60 days.
3. Replace with (a) breeding stock from
validated brucellosis-free herds or, (b) swine which have passed a negative
test for brucellosis conducted within 30 days prior to entry onto the premises.
Such swine shall be maintained under hold order on the premises, separate from
other swine, until they pass two negative tests for brucellosis not less than
90 days apart after date of entry onto the premises.
PLAN B. MAY BE USED WHEN ONLY A FEW REACTORS ARE FOUND AND
NO CLINICAL SYMPTOMS OF BRUCELLOSIS HAVE BEEN NOTED
1. Remove reactors from farm to slaughter
under official supervision.
2.
Retest herd at 30-day intervals, removing reactors, until entire herd is
negative.
Following two negative herd tests at least 90 days apart,
the herd may be released from hold
order.
(c) Cleaning and Disinfecting.
Premises shall be cleaned and disinfected under supervision
or proper direction of an official inspector following removal of reacting
animals.
(d) Biological
Products.
Owners shall not allow the use of any biological product or
vaccine for the prevention or treatment of brucellosis in a herd, unless
authorized by the Department.
(e) Validated Herds.
When two consecutive herd tests 60 to 90 days apart are
negative, the herd may be declared a validated brucellosis-free herd for a
period of 12 months or such other length of time that the department may
specify, provided all swine on the farm kept for feeding purposes shall be
segregated from the breeding herd until moved for slaughter. A certificate will
be issued to the owner by the cooperating Federal-State officials designating
the herd as brucellosis-free. Validation is made annually or at such other time
specified by the Department by passing a negative herd test.
(f) Validated Brucellosis-Free Areas.
Areas may be declared validated brucellosis-free for a
period of three years, provided:
(1)
All breeding herds in the area have been included in one of the following
within 18 months immediately preceding the declaration of the validated
brucellosis-free area status.
(A) Declared a
validated brucellosis-free herd;
(B) A complete herd test;
(C) Market Swine Testing Program for at least
three years, except newly assembled herds; such herds shall be in the Market
Swine Testing Program a length of time specified by the
Department.
(2) All herds
in which the existence of brucellosis has been established are handled
according to the provisions of (b) (4).
(3) Not more than three percent of the herds,
or one herd, whichever is greater, shall have been found to be infected on the
most recent test conducted during the 18 months immediately preceding the
declaration of the validated brucellosis-free area status.
(g) Maintaining Validated Brucellosis-Free
Areas. Validated brucellosis-free areas may be validated at the end of each
period of validation provided all the herds in the area are handled according
to the provisions of (f) and the herd infection rate does not exceed five
percent during the three-year validation period.
(h) Additions to Swine Brucellosis Control
Areas and to Validated Brucellosis-Free Herds.
(1) Replacement animals may be added without
test if procured directly from a validated brucellosis-free herd currently
listed or a negative herd in a validated brucellosis-free area.
(2) All other replacement breeding animals
shall have passed a negative agglutination test within 30 days and be held in
isolation until passing a second negative agglutination test. The second test
shall be at least 90 days after the first, in the case of boars and open gilts,
or after farrowing in the case of bred sows and gilts.
