Prof. Dr. Semsettin Ustacelebi, the Microbiology Main Division Chairman of Hacettepe University and a mad cow disease expert, explained that there was no example in the world that the mad cow disease was transmitted to the people through blood. Ustacelebi said that there was no need to panic but the ones that used the bloods must be followed.

Ustacelebi, who got his Ph.D. degree from Glasgow University and studies on mad cow, said, "This is not a virus disease, but an illness caused by molecules entitled prion. There is no factor fixed in the world as regards that it is transmitted to people through blood."
Ustacelebi added, "If the bloods in question, which were imported by Turkey, were used, there is no such thing that this disease was absolutely infected.
