Clinical signs of foot-and-mouth disease in pigs
A range of clinical signs may indicate the presence of foot-and-mouth disease (FMD) in pigs.
Typical clinical signs of FMD in pigs include:
- pyrexia, though this clinical sign is inconsistent
- severe foot lesions and lameness, with detachment of the claw horn, especially when housed on concrete
- vesicles on pressure points of limbs, especially along the carpus, resulting in knuckling
- vesicular lesions on the snout
