Near Sunland Park, New Mexico, eight horses recently tested positive for equine infectious anemia (EIA). Initially, two horses were found to be positive during a routine testing for a sale. The rest of their herd was tested immediately, and the remaining positive horses were found in that herd.

Three other groups of horses were fenceline adjacent to those horses, and authorities are testing all of those equines. At press time, no more positives had been found.
