It's a highly contagious viral infection that hits cloven-hoofed animals. Symptoms include fluid-filled blisters that appear in and around the animal's mouth, nose, teats and feet.
Is it dangerous to human beings?
No. Britain has recorded only one case, in 1966, of foot-and-mouth disease in a human. That occurrence was mild, transient and showed symptoms similar to those of flu, plus blisters on the hands. Humans cannot contract the disease through consumption of infected meat or from other people.
