01. Official EIA Tests. Official tests for EIA shall include the AGID test, the C-ELISA test and other EIA tests approved by USDA or the Bureau of Animal Health. (30-20-97)

a. Equine blood samples collected for official EIA tests shall be collected by a state or federal animal health official or a veterinarian who is licensed in the state in which the animal being tested is located.  (30-20-97)

b. Official EIA test samples shall be accompanied to the testing laboratory by an official EIA test report on which is recorded the name and address of the owner or person in charge of the animal, the breed, sex, age and identification of the animal being tested. Identification shall include identifying tattoos, brands, color and distinctive markings. The veterinarian or animal health official collecting the EIA test samples shall record the date the samples were collected and affix his signature to the official EIA test report.  (30-20-97)

c. Official EIA tests shall be conducted in a laboratory approved by USDA or the state of Idaho to conduct EIA tests.  (30-20-97)

02. EIA Is A Reportable Disease. All laboratories conducting EIA tests on Idaho origin equids and all veterinarians who diagnose EIA in Idaho equids shall report positive results of all EIA tests and diagnoses to the Bureau of Animal Health within twenty-four (24) hours of such test or diagnosis. Negative test results shall be reported within forty-eight (48) hours.  (30-20-97)

03. EIA Test Positive Animals Declared To Be Infected. Any equid which is positive to an official EIA test shall be declared to be infected with EIA and shall be designated as an EIA reactor. The Bureau of Animal Health may require or recommend a re-test of EIA reactors in order to confirm infection or identification of the animal. In cases where a confirmatory test is conducted, the final determination of infection will be delayed until the results of the confirmatory test are available. The animal on which a confirmatory test is to be conducted shall be placed under an official hold order until the results of the confirmatory test are available.  (30-20-97)

04. Disposition of EIA Reactors. Equids found to be infected with EIA shall be:  (30-20-97)

a. Quarantined to the premise where the animal was found to be infected, the owner's premise, or another premise that is approved by the Bureau of Animal Health.   (30-20-97)

b. The infected animal shall remain under quarantine until it is:  (30-20-97)

i. Consigned to slaughter at a USDA approved equine slaughter establishment, or,   (30-20-97)

ii. Euthanized and buried or incinerated, or,  (30-20-97)

iii. Donated to a university or other research facility for use in EIA research projects.  (30-20-97)

05. Isolation of EIA Reactors In Quarantine. The quarantine premise or area for EIA reactors shall provide no less than two-hundred (200) yards separation from all other equids. The quarantine area and quarantined animals therein may be monitored periodically by representatives of the Bureau of Animal Health to ensure that provisions of the quarantine are being met.  (30-20-97)

06. Identification of EIA Reactors. All equids found to be infected with EIA shall be identified with an "82 A" brand on the left neck or left shoulder of the animal. Identification as an EIA reactor shall be accomplished within fifteen (15) days of notification that the animal is infected with EIA. The "82 A" brand shall be at least two (2) inches high and may be either a hot iron brand or a freeze brand.  (30-20-97)

07. Testing of Exposed Equids. EIA exposed equids shall include all equids that are held, for at least seven (7) days, within two-hundred (200) yards of the location where an EIA reactor is or was maintained.  (30-20-97)

a. Exposed equids shall be placed under a hold order until the animals have been tested negative to EIA at least forty-five (45) days after the last reactor animal has been removed from the premise. Individual exposed equids, which have not had a negative forty-five (45) day test, may be allowed to move under hold order for specific purposes if they have a negative EIA test prior to movement. Such movement shall not be for longer than fifteen (15) days.  (30-20-97)

08. Findings and Effective Date. The amendments to IDAPA confer a benefit to the equine industry by protecting the equine industry against Equine Infectious Anemia.  (30-20-97)


Provided there is a written agreement between the Bureau of Animal Health and the chief livestock sanitary official of the state of destination, Idaho origin equids may be moved from Idaho for shows, rides or other equine events and return on an extended validity equine certificate under a state system of equine certification acceptable to the Bureau of Animal Health and the state of destination. The Bureau of Animal Health may authorize the movement of equidae into or out of Idaho on extended validity equine certificates under the following conditions:

01. Limitations Of Certificate. The movement does not involve the sale or change of ownership of the equid, animal breeding activities or movements that
involve stays of longer than ninety (90) days. Movements for these purposes shall be accompanied by a certificate of veterinary inspection.

02. Purpose Of Certificate. The movement involves short term travel to or from the state of Idaho for participation in equine activities, including but not limited to, participation in equine events, shows, rodeos, ropings, trail rides and search and rescue activities.

03. Completion, Reporting, And Approval Of Certificate. The extended validity equine certificate is properly completed, the required tests and certifications are recorded on the certificate and a copy of the completed certificate is submitted to and approved by the Bureau of Animal Health.

04. Certificate Validity. Extended validity equine certificates shall be valid for no longer than six (6) months from the date the EIA sample is collected, if an EIA test is required, or six (6) months from the date of inspection if no EIA test is required.

05. Reporting Itinerary. The recipients of extended validity equine certificates shall be required to submit a travel itinerary to the Bureau of Animal Health within ten (10) working days following the date of expiration of the certificate. The travel itinerary shall include a listing of all travel, including dates, purpose and destinations of travel, that the equid has made out of the state of Idaho during the validity of the certificate.

06. Cancellation Of Certificate. The Bureau of Animal Health may cancel any extended validity equine certificate in the event of serious or emergency disease situations or for certificate holders' failure to comply with the rules which apply to such certificates. Cancellation of the certificates may be accomplished by written or verbal notice to certificate holders. Verbal notice shall be confirmed by written notice. The canceled certificate will become invalid on the date and at the time of notification.

07. Findings And Effective Date. This new Section, IDAPA, confers a benefit to the equine industry by providing a reasonable, effective mechanism for interstate movement of equidae among the states of the region.
