Section 1. Authority. The following rules have been adopted by the Wyoming Livestock Board pursuant to the authority vested in it by Section 11-263, Wyoming Statutes, 1957, as amended.
Section 2. Adoption of Federal Regulations. The Wyoming Livestock Board hereby adopts the uniform methods, rules and regulations of the United States Department of Agriculture, Agricultural Research Service and the United States Livestock Sanitary Association, pertaining to the establishment of modified-certified areas, insofar as said methods, rules and regulations are not inconsistent with the applicable laws of the State of Wyoming.
Section 3. Quarantine of herds containing Infected Animals. Herds containing animals which give a positive reaction to an official blood test for brucellosis or which are otherwise determined to be infected with brucellosis may be quarantined; provided, however, that unbred heifers under twelve (12) months of age, spayed heifers and steers in such herds shall not be subject to such quarantine.
Section 4. Movement of Animals From Infected Herds.
a. Reactor animals from herds having members which give a positive reaction to an official blood test for brucellosis or which are otherwise determined to be infected with brucellosis shall not be sold, offered for sale, given away, or removed from the premises on which they are quarantined except upon a written permit from the board and under the condition that their destination shall be:
1. Immediate slaughter at an establishment operating under state, state-approved or federal meat inspection,
2. A public stockyard where federal inspection is maintained,
3. A registered quarantined feedlot,
4. A licensed Wyoming sale yard.
b. Negative animals from herds having members which give a positive reaction to an official blood test for brucellosis or which are otherwise determined to be infected with brucellosis shall not be sold, offered for sale, given away, or removed from the premises on which they are quarantined except upon a written permit from the board and under the condition that their destination shall be:
1. Immediate slaughter,
2. Summer range approved by the board,
3. A registered quarantined feedlot,
4. A licensed Wyoming sale yard, provided that when negative animals from such herds are sold, offered for sale, or given away, pursuant to written permit of the board, the condition of their health and of the herd from which they come shall be properly and truly represented and that they shall be specifically designated and represented as animals from infected herds, subject to re-quarantine and retest at the discretion of the board.
Section 5. Retesting of Animals Giving Suspicious Reaction. Animals which give a suspicious reaction to an official blood test for brucellosis in otherwise negative herds may be quarantined subject to an official retest, and shall not be removed from the quarantined premises other than for immediate slaughter or upon written permission of the board or its authorized representative until subsequently they are negative to an official blood test for brucellosis, or until it is subsequently determined by one (1) or more official blood tests made not less than thirty (30) nor more than ninety (90) days from the date of the suspicious reaction that the degree of reaction is stabilized or receding.
Section 6. 'Infected Herd' Classification Removed, How. The classification of 'infected herd' shall be removed from any herd if, subsequent to the finding of infection, all breeding animals of such herd pass two (2) consecutive negative blood tests for brucellosis made within a period of not less than one hundred twenty (120) days, or in the case of range or semi-range herds one (1) negative blood test for brucellosis made not less than one hundred twenty (120) days after the finding of infection if the state veterinarian, upon satisfactory evidence and in the exercise of judgment and discretion, makes a finding that all reactors and suspects were removed from such herd following the finding of infection and no abortions due to brucellosis have occurred in such herd following the finding of infection.
Section 7. Establishment of Modified-Certified Brucellosis Areas. Upon receipt of a petition signed by not less than 51% of the cattle owners representing not less than 75% of the cattle in a county, the Wyoming Livestock Board will designate the county as striving for Modified Certified Brucellosis status; and whenever it shall become known to the State Veterinarian that the disease of brucellosis exists among the cattle of such county, then it shall be mandatory on the part of all livestock owners in said county to participate in the brucellosis program; and it shall be the duty of the said State Veterinarian to take such steps as will prevent the spread of such disease with the State.
Section 8. Brucellosis Test for Breeding Cattle Moving from a Non-Certified County into a Modified Certified County. Breeding cattle moving interstate or intrastate (except official vaccinates under thirty (30) months of age) originating in a noncertified county, consigned to Wyoming approved sales rings and sold to a Wyoming destination in a modified certified area, must have negative brucellosis tests before leaving sales rings and must be held in quarantine at destination and retested in not less than 30 nor more than 120 days and found negative--all at owner's expense.
Section 9. Brucellosis Test for Breeding Cattle Moving from Sales Ring to Modified Certified Area. Breeding cattle moving interstate or intrastate (except official vaccinates under thirty (30) months of age) originating in a non-certified county, consigned to Wyoming approved sales rings and sold to a Wyoming destination in a modified certified area, must have negative brucellosis tests before leaving sales rings and must be held in quarantine at destination and retested in not less than 30 nor more than 120 days and found negative--all at owner's expense.
