A Quarter Horse gelding was confirmed positive with equine infectious anemia (EIA) on June 3. The horse was euthanized. The gelding had recently returned to Canyon County, Idaho, from Washington state and was being tested as a part of a large group for interstate movement. All exposed horses will remain under quarantine for a minimum of 60 days until they test negative.
A horse in the Squamish-Lillooet Regional District of British Columbia, Canada, was confirmed positive for EIA on May 29. The horse had been sampled by an accredited veterinarian at the owner’s request prior to moving the horse to another premise in Canada. No clinical signs of disease were noted at the time of sampling. A Canadian Food Inspection Agency (CFIA) investigation is underway. As per program policy, a quarantine has been placed on the infected horse and its on-premises contact animals. Initial reports indicate there are several equines on the affected premise. The quarantine will remain until all disease response activities have been completed, including follow-up testing and ordering the destruction of positive cases. Trace-out activities might require the CFIA to undertake actions at additional premises as outlined in the current policy.
