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.
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 VS-1-27 movement permit 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).
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). All bulls remaining in the herd from which an infected bull(s) has been identified would have to be tested two more times by culture or one more time by RT-PCR test. Any bull positive on the second or third test would be classified as positive. All bulls negative to all three culture tests or both RT-PCR tests would be classified as negative and could be released for breeding.
