Does Tuna Salad Go Bad? How Long Does Tuna Salad Last?

A tuna salad with mayo lasts up to 3 to 4 days in the refrigerator. Beyond this time, it is not safe to be eaten anymore.

The combination of fish and the mayo is not ideal for it to last longer than the above period. It is not particular to tuna salad, but also egg salad and chicken salad.

If the salad has not been packaged and stored correctly inside the fridge, it will not last longer than an hour. Mayonnaise stored at room temperature goes bad pretty fast. So it is best to discard it as it can cause food poisoning.

Unlike other items of food that can be frozen, a tuna sandwich cannot be frozen. It is because mayonnaise contains eggs as one of the main ingredients.

This causes a change in the texture and consistency of the salad. If you freeze a tuna salad, be prepared to be greeted with a soggy leftover.

The best way to store a tuna sandwich in the fridge is to put it in airtight freezer containers. This will keep the sandwich fresh for up to 5 days.

The time you store the sandwich also counts as well. You should store the sandwich within an hour of preparation if you know you will not eat it within the hour.

How to Tell if Tuna Salad is Bad? Tuna Salad Shelf Life!

The side effects of eating spoiled food can be very upsetting. So it is essential to recognize the signs of food getting spoiled before it reaches your mouth. Tuna or other dishes with fish as the main ingredient can be tricky to spot when it is going bad.

Fortunately for us, there are some signs that you can watch out to tell if the tuna salad has gone bad or not.

These include:

  • Bad appearance – Any type of discoloration is a sure sign that the tuna is already spoiled. The most common discoloration that shows up in a tuna sandwich is greenish and brownish spots. Dark black spots are also not uncommon. You would do well to discard it.
  • Unpleasant odor – Tuna has a naturally strong smell, so it’s not easy to go by smell alone. But if it smells pungent and unappetizing, be sure to get rid of it.
  • Duration of storage – Irrespective of the appearance and the odor, if you have stored the sandwich for more than five days, it is not safe to be eaten anymore.

The reason why tuna sandwich gets spoiled is a combination of warm temperature and the activity of microorganisms. The toxins from bacteria can cause a severe form of food poisoning called scombroid in humans.
