Scrapie is a fatal brain disease (TSE) of sheep and goats but is not known to pose a risk to human health.
Now you are just messing about.
If the wording was "is known not to pose a risk to human health" you might have a point.
Besides, sheep heads and spinal cords are being removed and destroyed within UK and Europe just in case. And there are no plans to stop doing this.
sorry I got my terms confused, I should have checked in case of SD pedantry! yes I am a registered food business etc etc.
