Are canned tuna (Ocean's) ready to eat?!
Answers: Without having to be cooked first?
it has already been cooked, to be canned, therefore it is safe to eat directly from the can. It's how you make a tuna sandwich! Same to be said for the tuna in pouches in the stores - its just not in a can. they are cooked and safe.
It it cooked in the cannig process...
All canned foods are ready to eat. (but not the soups)
