A lot of people recommending wiping with a cloth, but I would caution against that. It'll certainly make the carcass look more presentable, but a lot of hairs will simply be rubbed into alignment with natural creases and fold on the surface of the carcass, rendering them almost invisible. And hairs will also be rubbed off the cloth onto parts of the carcass that weren't previously contaminated.
The only really reliable way to get rid of hairs that adhere to the meat is to pick them off one by one. There should only be a few, if the skinning was done tidily.
