Foot-and-mouth disease is a highly contagious disease which can cause serious,
chronic illness in cloven-footed animals, such as cattle, swine (feral or wild
and domestic), sheep, goats, captive and wild deer, elk, bison and llamas. It
also can cause high mortality in young livestock, such as pigs. Infected
animals develop blisters in the mouth, tongue, muzzle, teats and skin between
the hooves. The disease has been diagnosed in 34 countries since January 2000.
