Another case of mad cow was found in Canada. Most likely the 6 year old was at a cow/calf farm.
This leads me to another story about scapie in sheep which is another form.
This is an interesting study from a Swiss University. The scrapie in sheep has been well know for a long time but it was not understoood how it was spread. Hopefully, other colleges/Universities will have studies to give further tesing to this Swiss study. Most good breeders of sheep in the US belong to the Scrapie program.
The British beef was traced back to feed made from scrapie infected food.
