On June 28, 2019, a positive equine infectious anemia (EIA) result was confirmed by the Canadian Food Inspection Agency (CFIA) national reference laboratory for a horse located on a premises in St. Paul County in Alberta, Canada. The horse had been sampled by an accredited veterinarian because it was exhibiting clinical signs compatible with EIA infection.

A CFIA investigation is underway and 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 premises.

The quarantine will remain in place 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.

Information for this report was provided by the Equine Disease Communication Center.
