(1) When rabies is known to exist within an area, the Montana Department of Livestock, Animal Health Division, shall, by order of the state veterinarian, establish a rabies quarantine area and shall define the boundaries of the quarantine area and specify the animals subject to quarantine.

(2) The area shall be quarantined for a period of not less than 60 days from the date of the last known case of rabies or as much longer as in the judgment of the Board of Livestock seems reasonable and necessary; provided that any dog or other animal under quarantine having been properly immunized against rabies under official supervision may be released from the quarantine area after a period of 28 days from date of vaccination.

(3) A list of counties or areas within counties under quarantine pursuant to this rule is kept at the Helena offices of the Department of Livestock. A copy of that list, and a copy of any specific rabies quarantine, is available without charge upon request to the state veterinarian.
