Number Confirmed: 1; 
Number Suspected: Unknown; 
Number Exposed: Unknown; 
Comments: On March 19, 2024, positive equine infectious anemia (EIA) results were confirmed by the Canadian Food Inspection Agency’s (CFIA) national reference laboratory for a horse located on a premises in Sainte-Damase, Quebec. The owners requested an accredited veterinarian test the horse for EIA prior to participation in a competition. No clinical signs of disease were noted by the veterinarian at the time of sampling. A CFIA investigation is underway and as per program policy, movement controls have been placed on the infected horse and any on-premises contact animals. Initial reports indicate there are other equines on the affected premises. Movement controls will remain until all disease response activities have been completed, including follow-up testing and ordering the destruction of confirmed cases. Trace-out activities may require the CFIA to undertake actions at additional premises as outlined in the current policy. Improved biosecurity protocols have been strongly recommended to the owners to help control the ongoing spread of EIA and protect our national herd.;
