1. (a) Bulls that have been determined to be infected by culture or by RT-PCR test and/or by confirmatory RT-PCR test shall be placed under hold order along with all other non-virgin bulls in the bull herd. Infected bulls must be isolated from all female cattle from the time of diagnosis until final disposition or as directed by the commission. Breeding bulls which have been disclosed as reactors may be retested provided: the owners, or their agents initiate a request to the TAHC Regional Director where the bull is located; that retests are conducted within 30 days after the date of the original test; test samples for retests are submitted to the TVMDL for testing; and the positive bull is held under quarantine along with all other exposed bulls on the premise. If they are retested, they must have two negative tests by RT-PCR to be released within 30 days of the initial test.
2. (b) Positive bulls may be moved directly to slaughter or to a livestock market for sale directly to slaughter. In order to move, the bulls shall be individually identified by official identification device on a movement permit authorized by the commission from the ranch to the market and from the market to the slaughter facility, or from the ranch directly to the slaughter facility. Movement to slaughter shall occur within 30 days from disclosure of positive test results (or confirmatory test results) or as directed by the commission.
3. (c) All bulls that are part of a herd in which one or more bulls have been found to be infected shall be placed under hold order in isolation away from female cattle until they have undergone at least two additional culture tests with negative results (not less than a total of three negative culture tests or two negative RT-PCR tests) within 60 days of the initial test unless handled in accordance with subsection (d) of this section. All bulls remaining in the herd from which an infected bull(s) has been identified must be tested two more times by culture or one more time by RT-PCR test. Any bull positive on the second or third test shall be classified as positive. All bulls negative to all three culture tests or both RT-PCR tests shall be classified as negative and could be released for breeding.
4. (d) Breeding bulls that are part of a quarantined herd or a herd that is under a hold order and tests negative to the first official Trichomoniasis test may be maintained with the herd if the owner or caretaker of the bulls develops a Trichomoniasis herd control plan with a certified veterinarian. The Trichomoniasis herd control plan shall require all breeding bulls to be tested annually with an official Trichomoniasis test and include other best management practices to control, eliminate and prevent the spread Trichomoniasis. The Trichomoniasis herd control plan, unless otherwise approved or disapproved by the commission, expires three years from the date the plan is signed by the herd owner or caretaker and the authorized veterinarian. Breeding bulls that are part of a Trichomoniasis herd control plan that expires or that is disapproved must be tested for Trichomoniasis as required by subsection (c) of this section.
5. (e) When Trichomoniasis is diagnosed in female cattle or fetal tissue, all breeding bulls associated with the herd will be restricted under a Hold Order for testing in accordance with this section.
