Frequently Asked Questions About Tuna water
Can you drink tuna water?
Yes, you can drink tuna water, but it may be salty and have a strong fish flavor. Check the can’s sodium information first, especially if you have been advised to limit salt, and don’t assume every brand uses plain water.
Should you drain tuna water?
Drain tuna water when you want firmer tuna with less liquid in a salad or sandwich. If you want extra moisture and fish flavor in a sauce or cooked dish, save a little instead of pouring all of it away.
Why is tuna water salty?
Tuna water can be salty because some cans pack the fish in brine to preserve it and add flavor. Other products use plain water, so check the ingredient list rather than assuming all tuna water has the same salt content.
Can tuna water be used in cooking?
Yes, tuna water can add fish flavor and moisture to savory dishes. Stir a little into pasta sauce, soup, or rice, then taste before adding salt; the packing liquid may already make the dish noticeably salty.
Is tuna water safe for cats?
A small amount of plain tuna water can be an occasional treat for a healthy cat. Avoid liquid that is heavily salted or contains seasonings such as onion, and don’t use it instead of fresh water or a complete cat food.
Is tuna water the same as the liquid in tuna canned in oil?
No, tuna water is the liquid from tuna packed in water or brine, while tuna packed in oil has oil as its packing liquid. They differ in flavor and how they affect the fat and texture of a recipe.
How should you store tuna water after opening a can?
Transfer tuna water and any leftover tuna to a covered food-safe container and refrigerate them promptly. Don’t store the leftovers in the opened can, and discard them if they develop an unusual smell or appearance.
Can you freeze tuna water?
Yes, you can freeze tuna water in a sealed freezer-safe container or ice-cube tray. Thaw it in the refrigerator and use it soon after thawing; its texture may change, but it can still work in soups and sauces.
Can you use tuna water in pasta?
Yes, tuna water can be stirred into pasta sauce for extra moisture and savory fish flavor. Add a little at a time, since too much can make the sauce watery, and taste it before seasoning with salt.
Does tuna water contain mercury?
Tuna water may contain small amounts of mercury that have transferred from the fish, although the amount varies. If you need to limit mercury, consider your total tuna intake rather than treating the packing liquid as mercury-free.

What is Tuna water?
Tuna water is the liquid left in a can of tuna after the fish is drained. Depending on the product, it may be plain water or a salty packing liquid. It carries a mild fish flavour and is usually drained off rather than served on its own; brined versions can taste noticeably salty.
Tinned tuna is commonly used in salads, sandwiches and pasta, and a little Tuna water can be stirred into these dishes for extra flavour. It is low in calories, with 8 calories and 1.3 g of protein per 100 g. Since salt levels vary, taste the liquid before adding it to a dish, or leave it out if you want to keep the meal less salty.
