Latest Information (as of February 17, 2006 - 13:30 EST)
The CFIA's animal investigation is complete. A total of 156 cattle from the affected animal’s birth cohort were identified and traced. All animals were accounted for and no additional cases of BSE were detected.
The feed investigation is nearing conclusion. A final analysis of records collected at the farm, retail and mill levels is underway.
In keeping with previous findings of BSE in Canada, the CFIA will prepare and publicly release a report summarizing the full results of the investigation.

CHRONOLOGY – BSE CASE 4, JANUARY 2006
January 16: A sample taken from a crossbred cow in north-central Alberta exhibiting symptoms of BSE consistent with the high risk categories of animals targeted under Canada’s national surveillance program for BSE was received by the Alberta Provincial Laboratory in Edmonton. The sample was obtained by a private practitioner under Canada’s national BSE surveillance program.
January 17-18: Analysis of the brain tissue sample demonstrated a reaction on the BIO-RAD rapid screening test. The analysis was repeated four times with similar reactivity. The status of the sample became INCONCLUSIVE. Per the international protocol the sample was sent to the national reference laboratory for BSE, CFIA’s National Centre for Foreign Animal Diseases (NCFAD) in Winnipeg for confirmatory testing.
January 19: The NCFAD conducted three separate rapid tests (BIO-RAD, Prionics Western Blot and Priostrip); samples demonstrated reactivity in all three tests. The status of the sample became SUSPECT. In parallel, analysis of the sample by internationally recognized "gold standard" tests for BSE (immuno-histochemistry (IHC) and Western Blot - SAF) commenced.
January 20: An experienced team of CFIA veterinarians and inspectors was dispatched to the farm of origin to conduct an initial epidemiological investigation into the animal health and feed aspects of this case.
January 22: NCFAD completed confirmatory testing and results were positive; the status of the sample was CONFIRMED POSITIVE.

i just cannot figure out why Canada, Japan and others do not have the same 4 to 7+ month 'sit on the shelf' policy as the USA before confirming a case of BSE? and then sometimes having to have an 'act of congress' to finally confirm a BSE case in the USA. maybe that is buried in the stupid OIE guidelines for BSE the USDA et al keep referencing. you know those BSE guidelines by the OIE, the same guidelines that most of the other countries that went on to developed BSE went by ;-)
