Canned tuna

Guidelines to store tuna in the fridge effectively 

There are some precautions you need to take when storing tuna in the fridge to keep it as fresh as possible for as long as possible. When you do not store it properly, it can go bad faster causing food waste. 

If you have fresh tuna, make sure there are no dry or brown spots. As soon as you get home from the market, put it in the fridge. Do not allow it to sit in the car or in the kitchen. 

Before preparing to put it in the fridge, pat it dry. Here are some more tips for safely keeping it in the fridge. 

Store it in a single layer 

Do not stack pieces of tuna on top of each other. Make sure each piece has its own space and its own bag for storage. Single-layer tuna stays fresh for longer. 

Seal it 

As stated above, make sure to pat it dry and then wrap it tightly in foil or plastic wrap. Make sure you put it in the coldest part of the fridge. If you are freezing it, you want to make sure to put it in a plastic wrap bag or vacuum-sealed bag with no extra air in it.

Ensure correct temperature 

Your fridge should be 40 degrees Fahrenheit to keep tuna safe. If the fridge falls below this temperature even for just a few hours, the tuna may not be safe to consume. 

Factors that affect tuna shelf life in the fridge 

There are many different factors that affect tuna when stored in the fridge. These change the way you should store the food and could contribute to the tuna spoiling faster. 

Other ingredients 

For example, if you make a tuna dish with mayo, the shelf life will be affected. Mayo usually causes the tuna to go bad faster. So if you make any kind of tuna dish with mayo you need to make sure you consume it within 3 to 4 days. 

If you make tuna with pasta, it will only last for about 4 days and tuna with egg usually goes bad within 5 days. 

Container Rigidity 

Any container you use needs to be airtight. If it’s not airtight, it can spoil faster because the air getting into the container causes the quality of the tuna to spoil faster. 

When you are putting raw tuna or cooked tuna in the fridge, make sure to put it in a bag or container with no air. This will keep it safe to eat.
