How long does a tuna sandwich last in the fridge?

Tuna sandwich can last for 3-5 days if it is stored at approximately 40°F or below in the fridge in an air-tight container according to the standards set by the USDA. 

As fish belongs to the meat class and they are characterized as highly perishable foods therefore they can not be stored too long once the can gets opened. Moreover the average shelf life of the second main ingredient .i.e. Mayonnaise is somewhat 5 days and that too when it is stored under the optimum conditions in a fridge.   

But we recommend you to eat your tuna sandwich within the first 24 hours because the mayonnaise and fish oils will make your bread really soggy and it won’t taste much delicious afterward.

How long does a tuna sandwich last at room temperature?

If you have left a tuna sandwich in open without covering it then it is recommended to use it within two hours or else there are chances of microbial growth to have started on it. You should get rid of the tuna sandwich that has been left uncovered at room temperature for more than an hour as 40°F to 140°F are the most feasible temperature conditions for the bacteria to grow and spoil your salad.

How should you store a tuna sandwich in the fridge?

You should always store tuna salad in air-tight containers or bags so that it won’t pick up the odor of any other food present in the fridge.

Moreover, it is better to store your tuna sandwich container on one of the shelves of the fridge rather than the door as the temperature fluctuates a lot at the fridge door while it is rather stable and cooler at the shelves. 

What is the optimum temperature to store a tuna sandwich?

You should always store your tuna sandwich at 40°F or below. Bacterial growth takes place at a faster pace between the temperature of 40°F and 140°F, therefore it is always advised to store your tuna sandwich at a lower temperature than this so that it won’t get infected with bacteria and other disease-causing microbes.
