Went to use some ground beef that had been canned in 09/12.  The inside of lid had some black spots on it.  Food smelled fine but I'm dumping it all.  How do I avoid this next time.

Mold is not poisonous.

Botulism is what you are worried about.  It's not a mold.

Just like raw meat, canned meat (if you are skeptical) is sterilized by boiling.  If you wish to consume it, instead of wasting it, boil it.

The black spots could be some minor corrosion from salt or acids. I've seen this on various canning lids after opening. Not a problem for me.
