Well well well what can one say a strain of virus that hasnt been extant for forty years suddenly infects a herd of cattle three miles from where it is being used to make vaccines against the disease.
I know that there will be several statements by the corporations involved saying that their procedures etc were watertight but its not rocket science to reason that if its the same strain that it came from there. After all it didnt magically apparate or come through the floo network now did it?
More pie in the face for Gordon.
Edit: as Zinzin would say; Gordon puts his foot in it!
