Bovine trichomoniasis requirements.

(1) Bulls (except bison) may be imported into the state of Washington if they meet the following requirements:
(a) The bulls originate from a herd wherein all bulls have tested negative for bovine trichomoniasis since they were removed from female cattle; or
(b) The bulls have tested negative to a bovine trichomoniasis quantitative polymerase chain reaction (qPCR) test within sixty days before import and have had no contact with female cattle from the time of the test to the time of import; or
(c) Rodeo bulls for timed events and bucking bulls have tested negative for bovine trichomoniasis within the past twelve months and have a statement on the certificate of veterinary inspection certifying that the bulls have had no female breeding contact; or
(d) If the bulls originate from a herd where one or more bulls or cows have been found infected with bovine trichomoniasis within the past twelve months, the bulls must have two negative qPCR tests one week apart. The samples for each test must be collected within thirty days before cattle are imported into Washington state, and an import permit must be obtained from the director and include a certifying statement that the bulls originated from an infected herd.
(2) Laboratory pooled qPCR samples collected from up to five bulls will be accepted if the following conditions are met:
(a) Bulls are twelve months of age and older that cannot be designated as virgin bulls and have had no breeding contact with females;
(b) Bulls originate from a herd where there is no history of trichomoniasis infection, and are part of a single herd, not assembled cattle; and
(c) Bulls are sampled for a herd diagnostic test without regulatory implications or are part of a disease investigation.
(3) Before arrival at their destination in Washington state, all imported bulls must be identified with official identification or an official trichomoniasis bangle tag.
(4) Bulls that enter Washington state without meeting the bovine trichomoniasis requirements of this section will be subject to a quarantine order or a hold order at the owner's expense until they have had two negative qPCR tests one week apart.
(5)(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 subject to a quarantine order or a hold order 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 subject to a quarantine order or a hold order 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.
(6) 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.
(a) All trichomoniasis testing of bulls in Washington state shall be performed by a veterinarian accredited by the USDA APHIS. In addition, all accredited veterinarians testing bulls in Washington state for trichomoniasis are required to successfully complete training and pass a trichomoniasis testing procedure proficiency examination provided by the department. Effective January 1, 2011, accredited veterinarians may not perform official trichomoniasis testing of bulls in Washington state until they have successfully completed the training and passed the proficiency examination.
A schedule of training opportunities is available by contacting the department at:
Washington State Department of Agriculture
Animal Services Division
1111 Washington Street S.E.
P.O. Box 42577
(b) Registered veterinarians shall only utilize official laboratories recognized by the state veterinarian for testing of trichomoniasis samples.
(c) Registered veterinarians collecting samples in the state of Washington shall submit results of all trichomoniasis tests and all official identification on official trichomoniasis test and report forms to the animal services division within five business days of receiving test results from an approved laboratory or identifying virgin bulls with official trichomoniasis bangle tags.
(d)(i) Polymerase chain reaction is accepted as an official test when completed by an approved laboratory and when the sample is received by the laboratory within forty-eight hours of collection.
(ii) Other tests for trichomoniasis may be approved as official tests by the state veterinarian after the tests have been proven effective by research, have been evaluated sufficiently to determine efficacy, and a protocol for use of the test has been established.
(iii) An official test is one in which the sample is received in the approved laboratory in good condition within forty-eight hours of collection. Samples in transit for more than forty-eight hours will not be accepted for official testing and must be discarded. Samples that have been frozen or exposed to high temperatures must also be discarded.
Exemptions to bovine trichomoniasis test requirements.
(7) Virgin bulls are exempt from bovine trichomoniasis test requirements. If sold, virgin bulls must be officially identified and accompanied by a certificate signed by the owner or the owner's designee that they have had no breeding contact with female cattle. "Virgin bull" means a sexually intact male bovine less than eight hundred pounds and less than twelve months of age, as determined by dentition inspection by an accredited veterinarian, that is certified by the owner or the owner's designee as having had no breeding contact with female cattle; or bulls that are less than eighteen months of age and have had no breeding contact with female bovines and originate from a herd where all bulls have been tested negative, by a quantitative polymerase chain reaction (qPCR) test, to trichomoniasis for the past three years.
