So there is no room for panic when it comes to meat consumption for humans. The CAE virus is intimately associated with white blood cells; therefore, any body secretions which contain white blood cells are potential sources of virus to other goats in the herd. The answer is no, there is no evidence that the CAE virus of goats can be transmitted to humans. One of the most common symptoms of the CAE virus is ”head-pressing”, which is when the goat stands with its head pressed against the wall.
