(Newser) – An English research lab is the likely source of a recent outbreak of foot and mouth disease, the Guardian reports. British government officials believe a batch of experimental vaccine leaked and spread to a nearby farm. Scientists were tipped to the possible leak by the fact that the strain of the virus is not one that occurs naturally, but is a vaccine strain.

The company is just three miles from the farm where the outbreak occurred.
A 10km "surveillance zone" has been established around the farm, to avoid a reprise of the catastrophic foot and mouth breakout in 2001 that cost the nation billions.
