Where do you get tuna fish juice?

Here's why:

* Tuna is packed in oil, brine, or water: Canned tuna is preserved in one of these liquids. While it might have some liquid from the packing process, it's not something you would typically drink or call "juice."

* Tuna juice isn't a food product: There's no commercial product specifically labeled as "tuna juice."

If you're interested in using tuna liquid for something:

* The liquid from canned tuna in water can be used in soups, stews, or sauces.

* The liquid from canned tuna in oil can be used for cooking.

However, it's not recommended to consume the liquid from canned tuna as a beverage.
