California Code of Regulations › Title 3 - Food and Agriculture › Division 2 - Animal Industry › Chapter 2 - Livestock Disease Control › Article 1.5 - Bovine Brucellosis › Section 754 - Brucellosis Area Classification

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Classifying Areas. The State of California participates in the brucellosis area
				  classifications of the USDA Brucellosis Eradication Program as published in
				  9 CFR, Part 78, section
				  78.41 (2015).
(b) Maintaining Area Classification. Area
				  classification shall be evaluated continuously through monitoring of all
				  brucellosis program activities. An annual report will be submitted by the
				  Department to the USDA documenting all California brucellosis surveillance
				  activities to determine eligibility for maintaining or changing area
				  classification. Area status may be maintained provided it can be established
				  that:
(1) All herds in the area are
				  participating in surveillance procedures designated by the
				  Department.
(2) All suspects to an
				  official brucellosis test:
(A) Are retested
				  until they are determined to be infected or non-infected, or
(B) If not available for retest, all known
				  contact animals or herds are tested or evaluated by a brucellosis
				  epidemiologist.
(3) The
				  number of herds found affected does not exceed specified limits.
(4) All cattle in an affected herd, except
				  steers and identified spayed heifers, are confined to the premises under a
				  quarantine until the herd has followed the procedures outlined in this section
				  and is determined to be free of brucellosis or sold for slaughter. All eligible
				  animals, as defined in section
				  752.3(e), shall be
				  tested (herd test). The herd is retested at 30-day intervals until the herd
				  passes one negative blood or other official test. Two (2) consecutive negative
				  herd tests are required for release of the quarantine. The first negative herd
				  test is conducted at least 30 calendar days after all reactors have been
				  removed. The second negative or releasing test occurs six (6) months or more
				  after all reactors have been removed.
(A) An
				  additional herd test is required either between six (6) months and 12 months
				  after an affected herd has been released from quarantine or between 12 and 18
				  months after the last reactor has been removed. Any variance to the retest
				  procedures shall be determined by the Designated Epidemiologist.
(B) All of the conditions in this subsection
				  also apply to herds that have participated in a whole-herd vaccination
				  plan.
(5) Herds adjacent
				  to and within one (1) mile of a premises occupied by a herd known to be
				  affected, herds sharing common pasture or having other contact with an affected
				  herd, or herds containing cattle from previous movements from an affected herd,
				  within a time period determined by the District or Designated Epidemiologist,
				  are placed under quarantine until each herd is evaluated. Herd tests, as
				  determined by the District or Designated Epidemiologist, shall be conducted as
				  part of the evaluation. The quarantine may be maintained until brucellosis is
				  eliminated from the area. When the quarantine is released on the brucellosis
				  affected herd, the District or Designated Epidemiologist reevaluates these
				  potentially exposed herds and notifies these herd owners of the need for
				  additional herd testing.
(6) All
				  other animals (any species) suspected of exposure to brucellosis infection, or
				  found to be infected with brucellosis, are placed under quarantine and
				  evaluated by the District or Designated Epidemiologist. If necessary, the
				  epidemiologist will design and implement an eradication and/or control program
				  suitable for the Brucella and animal species involved to prevent exposure of
				  livestock to brucellosis.
(7) Any
				  reactors found are disposed of in accordance with section
				  752.5 of this
				  article.
