If you use fresh tuna in your tuna salad, it will only survive for two days following the date of purchase, regardless of when you created the tuna salad.

If you use canned tuna, it should keep up to three days if kept in an airtight container in the refrigerator.

Tips on How To Safely Store Your Tuna Salad in The Fridge

I’ve included some recommendations for storing tuna salad safely in the fridge below. If you use these tips, you will be able to prolong the life of your salad and keep it taste fresh for up to 5 days after you prepare it!

  1. The easiest approach to preserve a tuna salad is to keep your components separate so that the oil from the tuna fish does not contaminate your green vegetables. Keep the tuna in two separate airtight containers, one holding the salad and the other containing any leaves or veggies. If you use a dressing on your tuna salad, keep it separate since oil, mustard, or vinegar may degrade both the vegetables and the tuna if left for too long.
  2. Keep your tuna salad in an airtight container, a sealed plastic container, or a glass container with a cover. This will keep the components from oxidizing too rapidly, causing meals to spoil faster. Keep all components at or below 40 degrees Fahrenheit (4 degrees Celsius).
  3. Place your airtight container at the back of the refrigerator. The coldest air tends to congregate here. Since the temperature is maintained below the danger zone, germs will not develop on your food and you will be able to store it for longer.
  4. By eliminating condensation buildup within your airtight container, you may increase the shelf life of your tuna salad. Place a piece of paper towel under the lid of your airtight container to do this. The sheet of paper will capture any extra moisture and protect it from contacting the tuna.
  5. Labeling the contents of your plastic containers is a smart idea. Especially if you name the container with the date, which acts as a nice reminder of when you made the salad and when it has to be utilized by.
  6. Keep your tuna salad apart from other items in your refrigerator. Other meats, especially raw ones, come to mind. This will aid in the prevention of cross contamination.
