A Foot and mouth outbreak at a Duchy of Cornwall farm on Dartmoor has prompted urgent checks of the local wildlife; for fear that free-range livestock are carrying the virus. Farmers commented that this is a "nightmare scenario." The Devonshire National Park has been home to over 40,000 free-range cattle and sheep for generations, and if the devastating virus identified at the Dunna Bridge farm cannot be linked directly to other outbreaks over 20 miles away, then the animals will have to be culled.
