BOZEMAN - The state Department of Livestock has confirmed that two horses in Gallatin County have a rare and contagious disease.
The horses tested positive for equine infectious anemia. Horses that contract the virus must be quarantined for life or euthanized.
Livestock Department spokesman Steve Merritt says investigators believe the horses contracted the disease at a recent out-of-state event. State law requires that all horses crossing into Montana be tested for the disease. One of the horses tested positive upon returning.
The Livestock Department has identified about 35 horses that may have pastured within 200 yards of the infected horses.
Merritt says he does not believe Gallatin County will have a widespread outbreak.
