Eating Moldy Food: When It's OK, When It's Not
Hard salami, or dry-cured ham
A thin, white coating gets the OK; anything out of the ordinary you’ll want to cut out.
“[In] some of the hard salamis, mold is actually added to produce a special flavor,” says Doyle. “In general those types of molds are considered to be safe.”
It’s normal for dry-cured country hams to develop some surface mold as well. So the ham should be safe to eat as long as you scrub the mold off first.
