32.3.1401. DEFINITIONS
(1) "Equidae or equids" include all horses (E. cabalus), asses (E. asinus), zebras (e. equiferus), their crosses, and other members of the equidae family as determined by the state veterinarian.

(2) "Equine infectious anemia" (EIA) is an infectious, contagious and potentially fatal viral disease of equidae.

(3) "Exposed equids" are equidae that have been in a herd with reactors or have been in contact with a reactor for 7 days or more at a distance of less than 200 yards.

(4) "Official EIA test report forms" are the USDA, APHIS VS form 10-11 or other similar form approved by the state veterinarian. A completed form must
contain official identification of the equid and must list the owner's name, the address and county of the animal's home premise, the name and address of the authorized individual collecting the test sample, the laboratory name and address, and the individual's name that conducted the test. The EIA test document shall list one animal only.

(5) "Official identification" of equine tested for EIA is a description of the equine to include the following: age, sex, breed, color, the animal's name and distinctive markings (e.g., color patterns, brands, tattoos, scars, or blemishes). In the absence of any distinctive color markings or any form of visible permanent identification (brands, tattoos, or scars) the animal must be identified by showing the location of all hair whorls, vortices or cow licks with an "X" on the illustration provided on an official form. Other forms of identification may be used as they are developed and approved by the state veterinarian.

(6) "Official tests" for EIA shall include the AGID test, the C-ELISA test and other EIA tests approved by USDA or the state veterinarian conducted by an approved individual at an approved laboratory.

(7) A "reactor" is an equid that is positive to an official EIA test. It shall be declared to be infected with EIA and shall be designated as an EIA reactor.

(1) 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, deputized and accredited in the state in which the animal being tested is located.

(2) Official EIA test samples shall be accompanied to the testing laboratory by a completed official EIA test report form. The veterinarian or animal health official collecting the EIA test samples shall record the date the samples were collected and affix his/her signature to the official EIA test report.

(3) Official EIA tests shall be conducted in a laboratory approved by USDA and the office of the state veterinarian.

(1) All laboratories conducting EIA tests on Montana origin equids and all veterinarians who diagnose EIA in Montana equids shall report positive results of all EIA tests and diagnoses to the department of livestock within one working day of such test or diagnosis. Negative test results shall be reported in the regular manner.

(1) The department of livestock may require or recommend a retest of an EIA reactor to confirm infection or identification of the animal. In cases where a confirmatory test is conducted, the final determination of infection shall 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.

(1) Equids found to be infected with EIA shall be quarantined to the premise where the animal was found to be infected, the owner's premise, or another premise approved by the department of livestock and are subject to the provisions of ARM Title 32, chapter 3, sub-chapter 1.

(2) The EIA reactor shall remain under quarantine until it is:
(a) consigned to slaughter at a USDA approved equine slaughter establishment;
(b) euthanized (or dies) and is buried or incinerated; or
(c) is donated to an approved university or other research facility for use in EIA research projects.

(3) Movement of any rector must be accompanied by a USDA, APHIS VS form 1-27.

(4) The quarantine premise or area for EIA reactors shall provide no less than 200 yards separation from all other equids. The quarantine area and quarantined animals therein may be monitored periodically by a representative of the department of livestock to ensure that provisions of the quarantine are being met. Any EIA reactor not held in quarantine may be ordered euthanized or sent to slaughter.

(5) All equids found to be infected with EIA shall be identified with an 81A brand on the left neck or left shoulder which will be followed by a number issued by the state veterinarian's office. Identification as an EIA reactor shall be accomplished within 15 days of notification that the animal is infected with EIA. The 81A brand shall be at least 2 inches high and may be either a hot iron brand or a freeze brand. The 81A brand will be assigned in sequence from the state veterinarian's office.


(1) EIA exposed equids, as defined by ARM 32.3.1401, shall be placed under a hold order until the animals have been tested negative to EIA at least 45 days after the last reactor animal has been removed from the premise. Individual exposed equids may be allowed to move under hold order for specific purposes as approved by the state veterinarian if they have a negative EIA test prior to movement. Such movement shall not be longer that 15 days.
