Understanding The Shelf Life Of Tuna Fish In The Fridge

Tuna fish is a nutritious seafood that’s packed with protein, vitamins and minerals. When it comes to storing this fish in the refrigerator, you need to be aware of its shelf life. In this article, we’ll take a look at why it’s important to know the shelf life of tuna fish and how long it lasts in the fridge.

Why Is It Important To Know The Shelf Life Of Tuna Fish?

Knowing the shelf life of your food is crucial as it helps ensure that you don’t consume anything that’s gone bad or lost its nutritional value. Eating spoiled tuna fish that’s past its expiration date not only tastes gross but can also lead to serious health consequences like food poisoning. Therefore, it’s vital to be mindful of the storage conditions and expiry dates of tuna fish.

Moreover, if you store the tuna properly, it maintains freshness for longer, reducing waste and saving you money. So, let’s find out how long we have before consuming our favorite tuna fish after buying from the grocery store or catching it ourselves.

How Long Does Tuna Fish Last In The Refrigerator?

The shelf life of tuna fish stored in the fridge depends on several factors like the type, texture, and quality of the fish and the temperature of the refrigerator. Canned tuna has a longer shelf life than fresh tuna since the canning process provides an airtight seal that prevents bacterial growth.

If you store fresh tuna correctly (wrapped tightly and kept at 0-4°C), then it will last up to three days in the refrigerator. However, cooked tuna should be eaten within two days of cooking, while raw tuna should be consumed within a day. Storing tuna at temperatures higher than 4°C will reduce its shelf life drastically.

Moreover, if you plan to freeze your leftover tuna fish for future use, place it in an airtight container or resealable plastic bag and store it at -18°C. Frozen raw tuna can last up to three months while cooked tuna can be stored in the freezer for two months.

“Fish stays fresh longer when the temperature is consistently colder than 40°F because the bacteria that spoils your food thrive best between 40°-140°F.” -Lilly Thibodeau

Consuming fresh and healthy tuna depends on how well you preserve it. To avoid food poisoning or waste of this nutritious seafood, ensure you know its storage times well and adhere to them strictly. By keeping your tuna fish correctly, you’ll enjoy its unique flavor and nutritional benefits every time you serve it.

Factors That Affect The Freshness Of Tuna Fish

Tuna fish is a popular type of seafood that can be stored in the refrigerator for later consumption. However, its freshness and quality may deteriorate over time due to various factors.


The temperature of the refrigerator is one of the most important factors that affect how long tuna fish lasts in the refrigerator. According to the USDA, tuna fish should be stored at a temperature of 40 degrees Fahrenheit or below to maintain its freshness and prevent bacterial growth.

If the temperature of the refrigerator fluctuates above 40 degrees Fahrenheit, it can accelerate spoilage and reduce the shelf life of the tuna fish. It’s essential to make sure that your refrigerator is maintained at a consistent temperature level throughout the storage period.

You can use a refrigerator thermometer to monitor the temperature inside your fridge. If you notice any inconsistencies, try adjusting the thermostat or seek professional help to fix any issues with your refrigerator’s cooling system.

Air Exposure

The exposure of tuna fish to air is another factor that affects its freshness and quality. When exposed to air, tuna fish can oxidize, leading to discoloration, an unpleasant odor, and flavor changes.

To minimize air exposure, it’s crucial to wrap the tuna fish tightly in plastic wrap or aluminum foil before placing it in the refrigerator. You can also place it in a sealed container with a tight-fitting lid to keep the air out entirely.

It’s recommended to consume tuna fish within two days after opening the package, regardless of whether it has been refrigerated or not. This is to reduce the chances of bacterial growth and ensure that you are consuming fresh and safe seafood.

Storage Container

The storage container you use to store tuna fish in the refrigerator also plays a significant role in maintaining its freshness. Tuna can absorb strong odors from other foods, which can affect its flavor and aroma.

It’s best to store tuna fish in an airtight container made of glass or food-grade plastic with a tight-fitting lid. Avoid storing it in containers made of metal as they can react with the acids in the fish and alter its taste.

You may also consider using freezer bags designed for storing seafood that comes with a zipper-lock seal to protect it from air exposure and extend its shelf life. Remember never to reuse any storage bag or container that previously held raw seafood to avoid cross-contamination.

“Tuna is very delicate. You don’t want to put it inside something without some sort of coating on it – maybe wrap it in wax paper first and then aluminum foil.” -Mark Bittman

Proper storage is crucial when it comes to extending the freshness of tuna fish in the refrigerator. Factors such as temperature, air exposure, and storage containers play significant roles in determining how long the tuna fish lasts while remaining fresh and safe for consumption.

How To Properly Store Tuna Fish In The Refrigerator

Tuna fish is a great source of protein and omega-3 fatty acids, making it a popular ingredient in many recipes. But after buying or caught your tuna, you may be wondering how long it lasts in the refrigerator. Here are some tips for properly storing tuna fish to ensure its quality and safety:

Wrap It Up

When storing tuna fish in the fridge, always wrap it properly to prevent exposure to air and bacteria. Wrapping the tuna tightly with plastic wrap or aluminum foil will keep it fresh longer and prevent odors from seeping into other foods.

“It’s important to store all seafood correctly to prevent bacterial growth. Use paper towels or clean cloths to pat seafood dry, then wrap it up tightly before placing it in the fridge.” -Seafood Watch

In addition, if you plan on freezing the tuna fish for extended periods, use freezer-safe bags instead of regular storage containers or wraps.

Store It In The Coldest Part Of The Fridge

The temperature at which you store tuna fish plays an essential role in preventing spoilage. It is recommended that you should store your tuna in the coldest part of your fridge. Typically, this area is towards the back where the temperature stays consistent.

If your fridge has drawers labeled “meat” or “seafood,” place the wrapped tuna in one of these compartments as they tend to have lower temperatures than the main fridge body. This will help retain the tuna’s freshness and quality much better than storing it in warmer locations like the door or top shelf.

Use An Airtight Container

Avoid using regular plates or bowls when storing tuna in the fridge as they do not provide an airtight seal, which can cause the fish to spoil quickly. Instead, use an airtight plastic or glass container with a tight-fitting lid. Make sure you wrap the tuna tightly in plastic wrap before placing it inside the container.

“Store raw and cooked seafood separately to avoid cross-contamination. Use clean wrapping materials when storing seafood.” -U.S. Food And Drug Administration (FDA)

If you are using a reusable container, make sure to wash it thoroughly with soap and hot water before storing your tuna. Also, mark the storage date on the containers for better tracking of its shelf-life.

Do Not Store It For Too Long

Tuna fish should not stay in your fridge for too long before consumption. While storing at 40°F or below can help keep your tuna fresh for up to three days, this time frame will significantly reduce if stored improperly or at higher temperature ranges like room temperature.

“Consumers should always buy perishable foods last, refrigerate them promptly after purchase, and follow basic food safety tips when handling and preparing them,” -Centers for Disease Control and Prevention(CDC)

To extend the tuna’s life, freeze it immediately upon purchasing or catching. Tuna that has thawed should be consumed within one to two days, so plan accordingly.

  • Try to use freshly caught or canned-tuna right away to get maximum taste and benefits.
  • Never leave packed tuna outside the fridge overnight or undercooked to prevent bacterial growth and related diseases.

Storing tuna properly is essential for ensuring its quality and flavor remains intact. Wrap it properly to prevent bacteria exposure, store it in the coldest parts of the fridge, use airtight containers, and be mindful of how long you store it.

How Long Does Tuna Fish Last in the Refrigerator?

Tuna fish is a popular seafood item that is packed with nutrition and offers numerous health benefits. It is rich in protein, omega-3 fatty acids, vitamins, and minerals. However, like any other perishable food item, tuna fish can go bad if not stored properly. So, how long does tuna fish last in the refrigerator? Let’s find out!

Smell Test

The first indicator of bad tuna fish is its smell. A fresh piece of tuna will have virtually no scent or only a mild sea-like odor. If your tuna starts smelling sour, metallic, or ammonia-like, then it has gone bad and should be discarded immediately. These are signs that bacteria growth has taken place, causing spoilage.

“If there’s an off odor, especially if it smells sharp or fruity, you shouldn’t eat it,” warns Carolyn Kumpe, manager of food safety programs at the City of New York Department of Health and Mental Hygiene.

Texture Check

The texture of tuna also changes when it goes bad. Fresh tuna meat should feel firm to the touch, but not hard like a brick. If you notice visible soft spots or a slimy residue on the surface, then the tuna is likely spoiled. Use a fork to check for texture changes; spotty or crumbly flesh signifies spoilage.

If you’re using canned tuna, open the container and carefully inspect the contents for any weird coloration, moisture, or mushy/soggy texture. Discard anything that doesn’t seem normal.

Visual Inspection

Another way to tell if your tuna fish has gone bad is by visually inspecting it. The flesh should be pinkish, red or brown depending on the variety of tuna fish. Any discolored patches (especially greyish, yellowish or green) are a sign that it’s no longer fresh and edible.

Discard any parts of the fish that appear to be bruised, mushy, or looks like it’s breaking apart. If you have purchased pre-cut pieces from your local fishmonger, make sure they look relatively meaty and not dull or depleted.

Taste Test

The last resort is to taste a small piece, which will help in detecting if anything went wrong during storage. Good quality raw tuna has a slightly sweet taste and soft mouthfeel. Cooked or canned tuna has more saltiness to its flavor profile.

“If something smells OK but you’re still unsure, check for signs of spoilage (like a slimy texture) when handling the food; these would signal bacterial growth,” advises “A quick sniff test should let you know whether or not your tuna has gone bad.”

If there’s even the slightest doubt about the freshness of the tuna, err on the side of caution and dispose of it. Consuming contaminated seafood can lead to an upset stomach, food poisoning, and other health risks.

  • It’s best to consume fresh tuna fish within two days after purchase.
  • The cooked variety lasts up to three to four days in the fridge, provided it’s stored correctly.
  • Canned tuna lasts up to five years or as per recommended expiry dates before opening, and a week once opened when properly refrigerated.

To get maximum benefits from eating tuna, make sure to buy fresh fish from trusted sources, store it properly in the refrigerator at 32°F to 38°F, and avoid consuming it past the safe use date.
