Number Confirmed: 1;
Notes: On January 7, 2021, 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 the rural municipality of Kinistino, Saskatchewan. The horse had been purchased in late summer and moved to the current premises along with a number of other horses. The horse was tested by an accredited veterinarian because it was exhibiting clinical signs that were compatible with EIA infection, it’s in a part of the province that has had several cases in at least four of the past ten years, and was associated with the pony chuck wagon industry in that area. 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 several 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.;
