Actually, this is poor skimming on your part. Émilie Jaumain - the person refered to in your first quoted paragraph - worked at INRAE and the lab there works on prions that can infect humans. She cut her finger, and became infected. Adriano Aguzzi's lab at the University of Zurich is the one that only works on mouse-adapted sheep prions. Presumably a similar accident wouldn't be possible there.
