How long does tuna salad last?

The length of time for which you can keep tuna salad depends on the storage conditions under which you keep it.

If you keep tuna salad at room temperature, it can last for 1 to 2 hours only. This is because fish and mayonnaise spoil easily. So you can not leave the tuna salad out for a longer duration. This time frame is also affected by the temperature. If the room temperature is less than 90 degrees Fahrenheit, tuna salad can last for two hours. But, if the room temperature is more than 90 degrees Fahrenheit, it can only last for 1 hour. Therefore, if you don’t want to let your precious tuna salad go bad, refrigerate it as soon as possible.

In the refrigerator, tuna salad lasts for 3 to 5 days. This relative increase in the shelf life is because of the refrigeration temperature that helps you keep the growth of microorganisms in control. As we know that the refrigeration temperature is generally equal to or below 40 degrees Fahrenheit, and according to USDA, the favorable temperature for bacteria to grow ranges from 40 degrees Fahrenheit to 140 degrees Fahrenheit. So, the less temperature inhibits the bacteria to grow on salad.

Can you freeze tuna salad?

If you want to freeze tuna salad, you have to consider the ingredients of the salad first. Because certain ingredients of tuna salad deteriorate the quality of the frozen salad when it is thawed. For instance, if tuna salad contains mayonnaise and you freeze it. The mayonnaise will not freeze well and will often separate, leaving an obnoxious texture to tuna salad. Similarly, if it contains crisp veggies like celery and onions, they will not freeze well. These vegetables will become limp after thawing and ruin the texture of tuna salad. However, salad dressings like miracle whip will do better in the freezer. But even if the texture of tuna salad is ruined, stirring the salad might be enough for you to enjoy, or atleast be okay with eating it.

How to store tuna salad to increase its shelf life?

To store tuna salad, either it is homemade or store-bought, you will need an air-tight container. Keep the salad in that container and refrigerate it. It is better to place the container of tuna salad on the shelf of the refrigerator rather than the doors as the temperature fluctuates more at the door of the refrigerator. The air-tight container will help you prevent tuna salad from absorbing the aroma of any other thing that is stored along with it in the refrigerator.

To make sure that the quality of tuna salad is retained during refrigeration, try to use a clean spoon to scoop the desired amount of salad in your plate and refrigerate the rest of it as soon as possible.

If tuna salad does not smell the same as fresh salad, and the smell seems to be sour or off in any way, it is better to discard such salad rather than to consume it.
