Tuna salad is a tasty and adaptable supper choice. A full meal filled with healthful ingredients that goes well on a sandwich, a tuna melt, or just on its own!

But, tuna, like other animal items, has a shelf life. In this post, we’ll look at how long tuna salad lasts.

Sadly, there is no straightforward solution to this issue. The truth is that the shelf life of tuna salad is affected by a variety of factors, including where it is stored, freshness, preparation techniques, container types, and so on.

As a result, we’ve separated our responses into several categories to examine how long tuna salad lasts under various conditions:

The Bottom Line

Let us begin with the most crucial piece of information. Tuna salad should keep in the refrigerator for approximately 3-5 days if refrigerated properly.

This, of course, assumes that you preserve your tuna salad appropriately, which we’ll go over next.

How Should I Store Tuna Salad?

The secret to giving tuna salad its 3-to-5-day shelf life is careful storage.

First and foremost, store the tuna salad in an airtight container.

Likewise, try to keep it apart from other foods while storing it. This is mostly to prevent the other items from absorbing the fishy flavor of the tuna!

Refrigerate your tuna salad at or below 40 degrees Fahrenheit. If you’re concerned about the tuna keeping cold, store it inside your refrigerator rather than on the door.

The door does not control temperature well, and the salad may be regularly exposed to outside temperatures (depending how often you open it).

Why You Should Store Tuna Salad At Or Below 40°F?

There are many reasons why tuna salad should always be refrigerated at or below 40 degrees Fahrenheit. The main reason for this is because germs grow at temperatures over 40 degrees Fahrenheit. It thrives best at temperatures ranging from 40 to 140 degrees Fahrenheit.

Bacteria may multiply quickly and overpower your diet in a few of days (or hours!).

Check the temperature of your refrigerator. And this is true for nearly any meat or seafood!

How Long Can Tuna Salad Be Outside Of The Fridge?

As previously stated, tuna salad should be stored at temperatures below 40 degrees Fahrenheit (ie. in the fridge). But what if you leave it out for a few hours by accident? Will it still be enjoyable?

In general, you should not keep food that spoils quickly (including tuna salad) out of the refrigerator for more than 2 hours. Any more than that, and you risk bacterial development on your meals. This danger is heightened if you have left the tuna salad in a heated room.

Simply simple, do not. Toss your tuna salad if it has been sitting for more than 2 hours. Even if it hasn’t gone bad, it may have dried out to the point that eating it would be disgusting.

How Do You Know If Tuna Salad Is Bad?

To begin, if your tuna salad violated any of the above guidelines, you may discard it.

The main method to determine whether tuna salad is rotten, like with any meat, is to smell it. We wouldn’t risk it if your tuna smelled off. It’s typically easy to detect when it comes to meat and fish. You shouldn’t risk it if it doesn’t smell like tuna.

Can You Freeze Tuna Salad?

Yes, technically. While freezing tuna salad will not inherently hurt it, it may impair its texture and integrity, resulting in a tuna salad that is not as enjoyable to consume!

It is mostly determined by the amount of moisture in the tuna salad. The more moisture that freezes, the more moisture that separates from the tuna salad, generating a significant change in texture and feel when it thaws again.

This is especially true if you use a lot of mayo in the tuna salad. As mayonnaise freezes, the liquid may separate from the mayonnaise, damaging its overall texture.

Hence, although freezing tuna salad is technically permissible, we strongly advise against it.

Putting it All Together

Don’t tamper with tuna salad that has been in the fridge for more than 3-5 days! Always seal firmly and keep refrigerated at temperatures below 40 degrees Fahrenheit. Furthermore, if your tuna salad seems or smells wrong, don’t eat it!

After all, few things taste worse than rotten tuna salad! And it’s so simple to manufacture more.


Thank you for taking the time to read our tuna salad guide! As you can see, the answer is straightforward, although it does depend on the circumstances. Be important to properly preserve all of your food, not just tuna salad.

And if you’re having trouble keeping track of your leftovers, consider labeling them with dates as you put them in the fridge!
