Description of affected population: the infected animal has been
determined to be a Charolais cow 81 months of age, born on 21 March 1998
on the same premises. There are 110 cows on the premises, 25 of which
are from the birth cohort. Additional birth cohorts have been traced to
seven other premises.

National Centre for Foreign Animal Disease (NCFAD), Winnipeg, Manitoba
western blot rapid test 9 Jan 2005 positive
National Centre for Foreign Animal Disease (NCFAD), Winnipeg, Manitoba
immunohistochemical test 11 Jan. 2005 positive

Source of outbreak or origin of infection: unknown or inconclusive.

Control measures:

A. Undertaken: quarantine.

B. To be undertaken: stamping out.

Treatment of affected animal: no.

Other details/comments:

Plans are under way for evaluation, depopulation, sampling and testing
during the week of 17-21 January 2005.

The infected animal was born on 21 March 1998. It is suspected that the
animal most likely became infected through the consumption of
contaminated feed at an early age.

No part of the animal entered the human or animal food systems. The
affected carcass was placed under quarantine before being transported to
a federal laboratory for incineration. A comprehensive epidemiological
investigation is under way.

In accordance with Article 2.3.13.5. of the Terrestrial Animal Health
Code , the
progeny born to the infected animal within the previous two years and
the birth cohort of the positive animal (animals born between 1 January
1997 and 31 December 1999 and which may have been exposed to the same
feed sources) are being traced. All such animals remaining alive will be
detained, their movements controlled and, when slaughtered, they will be
sampled for testing and completely destroyed.

Of the 349 animals from the birth cohort of the positive animal, 28 died
at birth, 162 were sold as calves, 43 were sold as yearling bulls, 91
are currently being traced and 25 are alive on the premises. These 25
animals remain under quarantine on the farm.

In parallel a thorough investigation of feed sources on the farm is
under way.

(1) TSE: transmissible spongiform encephalopathy

(2) ELISA: enzyme-linked immunosorbent assay
