> often visit farms in remote areas, collect samples when warranted. The
> sample in question today was taken from a cow that was at least 12 years of

> the sample with a preservative, which readies it for testing using the
> immunohistochemistry (IHC) test - an internationally recognized confirmatory
> test for BSE. Neither the rapid screening test nor the Western blot
> confirmatory test can be conducted on a sample that has been preserved.

> Our laboratory ran the IHC test on the sample and received non-definitive

> ?oslices? of tissue from this animal to determine whether or not it was
> infected with BSE. We will announce results as soon as they are compiled,
> which we expect to occur by next week.
