The Canadian Food
Inspection Agency has released three more sites from tuberculosis quarantines
that now remain on 50 sites in Alberta and Southwestern Saskatchewan.
The quarantines
were established when a cow tested positive for tuberculosis at a packing plant
in the United States.
That cow was
traced to a large operation in Alberta which keeps cows at 18 premises.
Tracing
movements in and out of that cow-calf operation prompted the CFIA to impose
quarantines on other farms and ranches.
There now are 23
farms and ranches that have been cleared from quarantines.
So far about
10,000 animals have been slaughtered, all on the 18-premises operation – to
prevent further spread of the disease.
Six animals from
that operation have been confirmed to have been infected with a strain of
tuberculosis that has never before been seen in Canada, but has been identified
in Mexico.
