Canned tuna salad is popular because of its nutritional value, how fresh it tastes, and how easy they are to prepare. In tuna salad, one of the main ingredients is mayonnaise. When you make this, you get the perfect blend of creaminess and crunchiness from the canned tuna, mayonnaise, onion, garlic, salt, black pepper, which all blend.
Anyone on a diet can replace the mayonnaise with mashed avocado or hummus. Typically, the albacore tuna fish sandwich is served on its own, so the chances of having leftovers are pretty high.
Rather than wasting it, you may decide to keep leftovers, but the question of the tuna salad shelf life comes into play. If you wonder how long tuna salad lasts, the answer entirely depends on the storage conditions. You should refrigerate tuna salad within two hours of preparation. In the case you purchased it, you’ll ask how long is tuna salad good for?

How Should I Store Tuna Salad In The Fridge?
Refrigerator doors are at different temperatures than refrigerator shelves. As a result, don’t keep tuna salad in the door as it will warm slightly every time you open the door. Instead, please keep it on a shelf in the refrigerator’s coldest section, which will be toward the bottom shelf.
When you refrigerate tuna salad, please keep it in an airtight container to avoid releasing an odor in your refrigerator or absorbing smells from other foods.
The combination of fish and mayonnaise isn’t good for lasting longer than the time specified, and this also applies to egg salad and chicken salad besides canned tuna salads.

If it isn’t wrapped or stored in your refrigerator, it can last an hour before bacteria start to reproduce. Mayo and eggs in any dish spoil quickly at room temperature and lead to food poisoning.
Why You Should Store Tuna Salad At Or Below 40°F
Bacteria can accomplish two things in food. It can be harmful and make us sick, or germs can ruin it.
Your food may develop an “off” flavor or texture, or it may show evidence of mold as dark spots, showing bacteria are present.
Unfortunately, pathogenic bacteria, or germs that cause illness, can be found on or in your food without you even realizing it. These bacteria can often be present without affecting your food’s taste, smell, or texture.
Bacteria thrive at their fastest between 40- and 140-degrees Fahrenheit. The USDA refers to this temperature range as the “Danger Zone.”
The growth of these germs is slowed by keeping tuna salad in the fridge at or below 40°F. If your refrigerator doesn’t have one built-in, a fridge thermometer can help with adequate food storage.
How Long Does Tuna Salad Last?
You can store your homemade tuna salad for between 3 to 5 days in the fridge. If it lies on the counter for more than two hours, it is no longer safe to eat and should be discarded.
That’s what USDA says about storing salads; also, what is the shelf life of canned tuna in the fridge after opening?
While tuna salads aren’t safe to eat after five days of storage, sometimes you could find your tuna salad is bad before this and may have to discard it earlier.
If your salad contains dairy products, these separate, and the salad might look and taste pretty bad after 2 to 3 days. It works the same way with homemade salad dressings. You can add a little vinegar or lemon juice to act as a preservative, yet this doesn’t give you much longer shelf life.
If you use store-bought mayonnaise or ranch dressing, it won’t separate, and that salad could maintain quality for five days when stored properly. (Read Do Radishes Go Bad)
How Long Can Tuna Salad Be Left Out Of The Fridge?
Because fish and mayo degrade rapidly, keep tuna salad out of the fridge long enough to scoop a portion or prepare a sandwich.
The government’s Food Safety website recommends discarding tuna salad if it has been above 40°F for more than two hours, but you need to consider your home temperature.
If the temperature is 90°F or higher, you may have 1 hour or 2 hours if the temperatures are lower.
How Do You Know if Tuna Salad Is Bad?
On top of what’s mentioned earlier, here’s all you need to know about how to tell if tuna salad is bad or how long does tuna salad last?
- Unopened tuna cans that are leaking, bulging, are corroded, or dented should be discarded.
- If your salad smells or looks “off,” don’t eat it. Eggs and fish in mayo quickly give an off odor.
- If your tuna looks and smells fine but tastes bad, don’t eat it and discard it.
- It grows mold or black patches. This means the tuna salad is poor.
- How long does tuna last in the fridge? It means five days max. Even if not ruined, over 5-days, discard the dish.
- The flavor is off, or the quality is poor. As previously said, several additions quickly degrade the salad. If yours is terrible or has changed texture, don’t force yourself to finish it.
Here’s a bit more in-depth to tell if tuna salad is bad.
Bad appearance: Any discoloration shows that the tuna has already spoiled. Greenish and brownish patches are the most common discoloration in tuna sandwiches. It’s also not uncommon to see dark black patches, so get rid of it.
Unpleasant odor: Tuna has a naturally strong smell, making it difficult to identify by scent alone. If there is an unappealing odor, get rid of it immediately.
Storage duration: If the bread tuna sandwich has been stored for more than five days, it is no longer safe to eat, regardless of its appearance or odor.
A combination of warm temperature and the activity of microbes causes a tuna sandwich to deteriorate. In humans, bacterium toxins can induce scombroid, a severe form of food poisoning, and should not be eaten anymore.
Can You Freeze Tuna Salad?
Tuna salad can be safely frozen in theory. But, unfortunately, the quality of your salad once thawed is determined by the ingredients employed in preparation.
Mayo does not freeze well and often separate, leaving your tuna salad with an unpleasant texture. If your tuna contains mayonnaise, don’t put it to freeze.
Crisp veggies like celery and onions typically become limp after thawing, ruining the texture of your tuna salad.
Freeze a single serving in a freezer-safe container or freezer bag as soon as possible after making it.
However, this nutritious salad has a relatively short shelf life. This is the primary reason most people would make fresh tuna sandwiches instead of consuming a refrigerated leftover tuna sandwich. (Learn How To Heat Pastrami)
