Discolored Aluminium Foil - Can it still be used?

I have some aluminium foil that I have been using for a while. Instead of being shiny as it used to, certain parts of it has turned dull and discolored like a muddy dark grey. Can I continue using it? Does it have any harmful effects on the human body? Thanks.

1. Heck Yes!
2. The cause of your problem would be oxidation/corrosion which can be caused by acidic food or just being old to be safe i'd throw it out and avoid any harmful affects.
3. yes. it's a metal, so it just oxidized some. when mine gets like that, i just use it on the grill. but it's still perfectly safe.
