(4)(a) Any bull or cow that is positive to a trichomoniasis test, and any herd in which one or more bulls or cows are found infected with trichomoniasis is considered infected.
(b) In the case of bulls testing positive to trichomoniasis, the herd shall be quarantined pending an epidemiological investigation to determine the source of the infection, and as long as infection persists in the herd.
(c) Infected bulls will be quarantined and will not be used for breeding. They must be slaughtered, sold for slaughter, or sent to a restricted feedlot or category 2 restricted holding facility to remain in slaughter channels.
(5) Certification and proficiency testing and types of tests. The state veterinarian will determine trichomoniasis training for veterinarians and laboratories, and the types of tests used to determine trichomoniasis infection. All sampling will be obtained by pipette scrapings from the prepuce and glans of a bull.
