What is Foot and Mouth?
Acute viral infectious disease
Begins with fever, followed by the development of vesicles on mouth and feet
Very infectious and spreads rapidly
Wild and domesticated cloven hoofed animals are affected
Rarely fatal, but pregnant animals often abort and dairy cattle may dry up
Illustration
Universal Symptoms of Foot and Mouth Disease
Shivering
Tender and sore feet
Slobbering and smacking lips
Blisters on hoof, feet, snout, or tongue
Clinical disease and diagnosis
All species of cloven-hoofed animals are susceptible to FMD, including domestic livestock and wild ungulates. Clinical signs are essentially similar in all species although the severity may vary.
Specific signs in Cattle
Slobbering and smacking lips
Shivering
Tender and sore feet
Reduced milk yield
Sores and blisters on feet
Raised body temperature
Specific signs in Sheep
Sudden, severe lameness
Lying down frequently and unwillingness to rise
Reluctance to move
Blisters found on the hoof, dental pad and sometimes tongue
Specific signs in Swine
Sudden lameness
Preference to lie down
Loud squeal and hobbling when set into motion
Blisters may develop on snout, tongue and/or hoof
Important!!
Swine Vesicular Disease has identical symptoms to FMD. Therefore anyone who sees blisters in pigs must report the sighting as suspected FMD, until laboratory tests prove otherwise.
