I’ve heard more info on bluetongue which seems to correct some earlier inaccuracies on here including some uttered by me.
Bluetonge is apparently a serious disease that makes animals very ill and is fatal to a significant proportion – particularly among sheep.
While this disease can’t be spread directly from animal to animal, it can be spread via the midges that bite an infected animal and pass on the disease to other animals they bite.
If these facts are true, then culling and restricted zones make more sense.
With FMD and bluetongue about, I wonder if there will be some poor hapless beast that is found to be suffering form both.
