OIE has recently declared a foot and mouth disease (FMD) outbreak in Morocco. It is thus necessary to remain alert to the possible appearance of FMD lesions at the slaughterhouses. In this post a few FMD lesions are reviewed.

Cattle are the species with the most conspicuous lesions, the disease, however, can involve any cloven-hoofed animals (cattle, buffalo, sheep, goats, pigs…). Suspected lesions must be compulsory reported to the authorities.

 

Table 1: Typical FMD lesions.

Typical FMD lesions Antemortem changes
Bovine Sores and blisters in the oral mucosa, the tongue and the feet. Fever

Shivering

Lameness

Slobbering

Ovine Sheep rarely develop mouth blisters as a result of foot and mouth disease: lameness is the main sign of the disease.

Blisters on the hoof are more common. In either location the blisters tend to be very small and hard to spot.

Lameness
Porcine Pigs rarely develop mouth blisters as a result of foot and mouth disease: lameness is the main sign of the disease.

When blisters appear they can be found at the upper edge of the hoof where the skin and horn meet, on the tongue and on the snout.

The lesions are indistinguishable from swine vesicular disease.

Pain and apathy
