A classic lunchtime snack or meal, tuna salad is an economical and versatile option. Most of the time, mayonnaise is used, but you can easily use Greek yogurt, hummus, or avocado instead. You can also add crunchy vegetables like celery and onions. You can make your tuna salad even better by adding spicy foods like dill or lemon pepper or sweet foods like relish. It tastes great on its own, in a lettuce wrap, on a sandwich, or with crackers. Its no wonder that many people often make a large batch of it at a time.
Worry about how to tell when leftover food starts to go bad is common for all kinds of food, including tuna salad. Wasted food can make you sick. Symptoms of food poisoning from eating bad tuna salad can include vomiting, stomach cramps, and diarrhea. You can tell if tuna salad has gone bad in a number of ways, such as by looking at it or smelling it. You can also find out how long tuna salad is good for.
Tuna salad is a versatile ingredient that can be used in sandwiches, wraps on top of salads or eaten as a snack. It’s convenient to make a big batch to have on hand throughout the week. But how long does homemade or pre-made tuna salad last in the fridge?
As a tuna salad lover, I was determined to find out the maximum refrigeration time for optimum freshness and food safety. After consulting food safety experts, I now have the definitive answers on storing tuna salad in the fridge.
How Long Does Tuna Salad Last Refrigerated?
Properly stored tuna salad will maintain best quality for
-
3-5 days in the refrigerator for homemade tuna salad.
-
3-4 days for store-bought pre-made tuna salad.
-
5-7 days if frozen in an airtight container.
These timelines are for tuna salad stored at 40°F or below. Higher refrigerator temps shorten shelf life.
No matter what, tuna salad should not be left at room temperature for more than 2 hours before putting it back in the fridge. The mayonnaise-based mixture can go bad quickly at warmer temperatures.
How to Tell When Tuna Salad Has Gone Bad
Rely on your senses to determine if tuna salad has spoiled. Signs of spoiled tuna salad include:
- Sour or rancid smell
- Separation of ingredients
- Liquid pooling around the mixture
- Mold growth
- Unusual changes in color or texture
If you notice any of these red flags upon inspection, it’s best to discard the tuna salad. Consuming spoiled tuna salad can potentially cause food poisoning.
Whenever there is doubt over the freshness, remember the old adage: “When in doubt, throw it out.” Tuna salad is inexpensive and easy enough to make fresh.
Tips for Maximizing Fridge Life
Follow these storage tips to get the most mileage from your tuna salad:
-
Prepare tuna salad with high-quality ingredients like fresh tuna and real mayonnaise.

-

When thawing frozen tuna salad, do so in the refrigerator rather than countertop.
With proper storage techniques, you can enjoy tuna salad for lunches most of the work week.

Look for visual clues
One way to tell if your tuna salad has gone bad is to look for any changes in appearance. If you see any signs of mold or any green, brown, or dark spots on your tuna salad, then you should toss it out without even tasting it. Although it is possible to salvage some moldy items, like certain hard cheeses, cured meats, and fruits, by cutting off the moldy parts, tuna salad is not one of them, as you may not be able to see the mold spores that could have contaminated the other portions of the tuna salad.
If you see any sign of mold, dont sniff the tuna salad either, as that can cause respiratory issues from inhaling the mold, per the USDA, which also recommends keeping food items covered, even when being served, to prevent mold spores from spreading. So dont leave your tuna salad out uncovered for any length of time, and remember to promptly refrigerate it, ideally in an airtight container.
Most of the time, food that is going bad smells bad because microbes like bacteria and mold that are growing in it are making chemicals that make the food smell bad. With just your nose, it might be hard to tell if tuna or tuna salad has gone bad because of how strong the smell is to begin with. Of course, if you open your leftover tuna salad and smell something fishy, funky, or otherwise off, you should probably throw it away right away because it has gone bad.
Just because the tuna salad doesnt smell off doesnt mean that it hasnt spoiled or gone bad. According to Tufts Now, many microbes that cause food-borne illnesses dont actually give off a noticeable smell when they start growing in food, so dont take the absence of smell as a definitive indicator that your tuna salad is still good.
How long is tuna salad good for?
According to the USDA, tuna salad, assuming it has been stored properly in the fridge at temperatures below 40 degrees Fahrenheit, is good for 3 to 5 days before it starts to spoil. Its important to refrigerate any leftover tuna salad promptly. Dont let it sit out at room temperature for more than 2 hours (or 1 hour when its more than 90 degrees Fahrenheit out). Using an airtight container will keep your tuna salad fresher for longer, and also wont let smells in or out. You should also store the tuna salad in the coldest part of your fridge, and not in the door.
Most of the time, tuna salad doesn’t freeze well because it’s made with mayonnaise, which separates when frozen. Crunchy items like veggies can also lose their crunch and become mushy once frozen. If you made your tuna salad with simple ingredients and mayo substitutes that work better when frozen, like yogurt or hummus, you may be able to freeze it and use it later. You can freeze tuna in a can by itself for up to three months. Yogurt can be frozen for up to two months, and hummus for up to four months.
