Only 10 premises now remain under quarantine. They have
1,100 cattle.
The investigation began a year ago when a cow from Alberta
tested positive at an American beef-packing plant.
That prompted a quarantine on the originating farm, which
consisted of a number of premises and more than 11,500 cattle.They were all slaughtered.
Testing identified another five cattle with a strain of
tuberculosis previously never found in Canada.
The CFIA then set about identifying every farm that bought
animals from that operation within the previous five years.
They were all quarantined while the CFIA tested all of those
cattle for TB. None were infected.
The case was one of the largest conducted by the CFIA and
involved farms and ranches throughout southern Alberta and southwestern
Saskatchewan.
