I decided to do some googling about this. One site said it's okay if there were no leaks caused and mentioned some ways to tell. It also said that dings on any of the seams are bad and to throw it out if there are any. There is a ding very near the bottom seam.
I started to wonder about the lining of the can. Can bits of that fall into the food where it gets bent by a ding? I haven't been able to find anything about that - just lots of sites telling me that most cans don't have a BPA lining anymore.
Yeah, I think that I'll skip eating the contents of that can. Now, should I open and empty and wash it so it can go in recycling? Or should I just chuck it in the garbage?
