Mold on salami, is it safe?
It's one thing to buy salami which comes with its own built-in mold, but to let one develop some possibly different mold spontaneously in the fridge?  If nothing else the fridge would not provide the ventilation which I understand is an essential part of the process (that's why you hang them and don't pile them up on a shelf).

Worse, I see a seam on the casing, which implies that it's a plastic casing and not a natural one.  I would not eat something which grew on plastic..
