Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The department proposed to amend chapter 16-86 WAC to add trichomoniasis to the rule. The department is proposing to add definitions, add a new section outlining the process and testing requirements, and add training requirements for veterinarians that will be performing the trichomoniasis testing.

Reasons Supporting Proposal: These changes are necessary to prevent the spread of disease in the state and to protect the public's health and welfare.

Statutory Authority for Adoption: Chapters 16.36 and 34.05 RCW.

Statute Being Implemented: Chapter 16.36 RCW.

No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.030 (1)(a) requires that an agency prepare a small business economic impact statement (SBEIS) for proposed rules that impose a more than minor cost on businesses in an industry. The department has analyzed the economic effects of the proposed revisions and has concluded that they are negligible costs on the regulated industry and, therefore, a formal SBEIS is not required.

A cost-benefit analysis is not required under RCW 34.05.328. The Washington state department of agriculture is not a listed agency under RCW 34.05.328 (5)(a)(i).

WAC 16-86-115   Trichomoniasis in Washington cattle.   (1) Any sexually intact bovine, except for bison, that is found test-positive for trichomoniasis, and any herd in which one or more bulls or cows are found test-positive for trichomoniasis, is considered infected. Test-positive means a positive result on a quantitative polymerase chain reaction (qPCR) test for trichomoniasis.

(2) In the case of infected sexually intact bovine, the herd shall be quarantined pending an epidemiological investigation to determine the source of the infection.

(3) All exposed herds will be identified by an accredited veterinarian in conjunction with the department. An exposed herd is defined as a cattle herd which has had, within the past twelve months, direct commingling or cross-fence contact with an infected herd during a time of potential breeding activity. The owner of exposed herds will be notified of the possible exposure and requested to test the herd using a qPCR test. All testing will be at the owner's expense.

(4)(a) Infected bulls will be quarantined and branded high on the tail head by the department with a USDA regulatory S-brand, and will not be used for breeding.

(b) Infected bulls must be slaughtered, sold for slaughter, sent to a restricted feedlot, or to a category 2 restricted holding facility to remain in slaughter channels. Infected bulls shall only be moved when accompanied by a USDA form VS 1-27.

(c) Bulls of unknown origin offered for sale at a livestock market must be tested negative for trichomoniasis by a qPCR test before being turned out with breeding stock or must be sold for slaughter, sent to a restricted feedlot, or to a category 2 restricted holding facility to remain in slaughter channels.

(d) A nonpregnant female, with no calf at side, which is identified by the owner as being from an infected herd and is offered for sale at a livestock market, must remain in slaughter channels.

(5) The quarantine will be removed when all remaining bulls in the herd test negative to a second qPCR test for trichomoniasis and following proof of removal of infected bulls. Bulls must have a minimum of two negative qPCR tests at least one week apart for quarantine release. All bulls from infected herds, except virgin bulls, will be tested using a qPCR test the following trich-year before breeding. A trich-year means the period from September 1st to August 31st of any given year. Bulls from infected herds may not have to be tested the following trich-year if a herd plan has been approved by the state veterinarian.

(6) Information that cattle have tested positive for trichomoniasis may be supplied to county extension agents, accredited veterinarians, and industry representatives. Each month, the department may publish a press release of counties that have infected herds.


WAC 16-86-116   Duties of certified, accredited veterinarians -- Training requirement for veterinarians performing trichomoniasis testing in cattle.   (1) Effective January 1, 2011, accredited veterinarians may not perform official trichomoniasis testing of bulls in Washington state until they are certified to do so by having successfully completed training and passed a proficiency examination provided by the department.

(4) Certified veterinarians shall utilize only official laboratories recognized by the state veterinarian for testing trichomoniasis samples. Positive test results will be sent to the department by the next business day.

(5)(a) Quantitative polymerase chain reaction (qPCR) is the test method for official tests accepted by the department.

(b) An official test is one in which the sample is collected by a certified veterinarian and received in the official laboratory in good condition within forty-eight hours of collection. Samples in transit for more than forty-eight hours or have been frozen or exposed to high temperatures will not be accepted for official testing.
