Scabby mouth, also called orf, contagious ecthyma or contagious pustular dermatitis, is a viral disease (poxvirus) affecting sheep and goats.
Scabby mouth is highly contagious, with infection occurring through direct contact with the virus which can survive in the environment for more than one year.
Grazing of coarse pastures and thistles may predispose stock to infection with Scabby Mouth as oral abrasions increase the potential for the virus to gain entry.
Scabby mouth most commonly affects lambs in first year of life, but also can occur in older sheep.
Scabby mouth commonly affects the lips, mouth and surrounding skin, but can also affect the face, feet and the udder of nursing ewes.
Severely affected lambs are unable to feed with loss of condition and depressed growth rates.
There is no treatment for scabby mouth, so prevention by vaccination is important. The recommended program is to vaccinate each year’s crop of lambs. This is generally done at docking/tailing.
This virus is transmissible to humans, causing skin lesions. It is therefore recommended that people handling infected sheep should wear appropriate protection.
