051-2 Wyo. Code R. §§ 2-8 - Testing of Specific Bovinae

(a) Within the DSA, all Test Eligible Bovinae and any Heifers born during the previous calendar year and shipped after August 1 of their yearling year are required to test negative for Brucellosis within 30 days prior to a change of ownership, prior to interstate movement, and prior to leaving the DSA. Any negative test result reported between August 1 and January 31 of the following calendar year will be valid from the time of test until the end of that time period (January 31).

(i) The following are exemptions from this testing requirement:

(A) Test Eligible Bovinae that move to a Wyoming Approved Livestock Market or to an out-of-state livestock market that appears on the Wyoming State Veterinarian's list of Out of State Markets Approved for Brucellosis Market Testing can be tested at the market prior to leaving and held there until results are determined to be negative if the identity of the Herd of Origin is maintained and each animal is individually identified with the following Board approved identification.

(I) "DSA Origin - Brucellosis Test Required" shall be written in the brand inspection document for Test Eligible Bovinae leaving the DSA.

(II) "Brucellosis Area of Concern Origin - Brucellosis Test Required" shall be written in the brand inspection document for Test Eligible Bovinae leaving a Brucellosis Area of Concern required by the Board to be subject to the testing requirements of these rules.

(B) Out-of-state origin Commuter Herds moving from Wyoming, pursuant to an Interstate Livestock Health Movement Permit with an adjacent state, will have test requirements specified in the commuter agreement. For cattle in the DSA between August 1 and January 31 of the following calendar year no test will be required unless deemed necessary by determination of unusual risk. For cattle in the DSA any time between February 1 and July 31, Wyoming recommends a full joint risk analysis between the two state veterinarians to determine the appropriate number of animals to be tested. Regardless, a minimum of 20 percent of the herd, to include open, late-bred, and cull cows, will be tested prior to or upon return to the state of origin. A copy of the Commuter Permit must be provided prior to issuance of a brand certificate for leaving. Movement and test documents will be required to be provided by the owner each year for renewal of Commuter Permit.

(C) Wyoming herds that complete a Brucellosis Risk Assessment and have in place a Brucellosis Mitigation Plan may have test requirements waived in accordance with the Mitigation Plan.

(I) Each Brucellosis Risk Assessment will be categorized as one of the following:

(1.) Insignificant risk: No documented exposure or feasible risk of exposure to Brucellosis-infected wildlife during the risk period of February 1 through July 31. No restrictions or requirements.

(2.) Potential Risk: No documented exposure, but risk of potential exposure by commingling or close proximity to Brucellosis-infected wildlife during the risk period of February 1 through July 31. Surveillance testing required.

(3.) Significant Risk: Documented exposure by commingling or close proximity to Brucellosis infected wildlife, or high risk of exposure to Brucellosis-infected wildlife during the risk period of February 1 through July 31. Cooperative mitigation and surveillance testing required.

(II) Without a Brucellosis Risk Assessment and Brucellosis Mitigation Agreement, all herds within the DSA and, when required by the board, herds within a Brucellosis Area of Concern, must meet all Chapter 2 requirements.

(D) Female Bovinae moving from a Herd with a valid Brucellosis Mitigation Plan will not be subject to additional testing other than that outlined in the Brucellosis Mitigation Plan, unless required by the Wyoming State Veterinarian under another provision of law.
