cooked but...
in the can or the pouch, it is cooked.. but, don't let that stop you from cooking it. I have eaten more than my fair share of tuna straight out of the can, so much so, that I just can't take it anymore. I like to heat up some olive oil, throw in some fresh ginger and stir fry the tuna from the can (careful, the tuna in water spatters in hot oil) in the oil and ginger -- really tasty. Also, you can of course get raw tuna from the super market and cook it yourself -- also very good -- very different taste than canned tuna.
