In this article, we’ll dive into the shelf life of Subway’s tuna and provide some tips on how to ensure your sandwich stays fresh and safe to eat.

So, if you’re a fan of Subway’s tuna or just curious about its longevity, keep reading!

How Long Does Subway Tuna Last?

According to Subway’s corporate guidelines, their tuna can stay out in the store’s refrigerated sandwich bar for up to 72 hours. This means that if you purchase a tuna sandwich from Subway, it should be consumed within three days of being made.

However, if you have leftover tuna that has not been placed on bread, it can last for up to four days if stored properly. It’s important to keep the tuna in an airtight container in the fridge to prevent bacteria growth.

It’s also worth noting that the freshness and quality of the tuna can vary depending on the supplier and how it’s prepared. Some Subway employees have reported that the tuna comes in a pressed, vacuum-sealed slab that is soaked in salt water. Others have claimed that it’s flaky and mixed with mayo.

Regardless of how the tuna is prepared, it’s important to follow food safety guidelines and consume it within a reasonable timeframe to avoid any potential health risks.

What Is Subway’s Tuna Made Of?

Recently, Subway has been facing a lawsuit alleging that their tuna sandwiches do not contain any actual tuna. The lawsuit claims that Subway’s tuna sandwiches are made with pork, chicken, and no detectable traces of tuna DNA. Subway has denied these claims and insists that their tuna is indeed made with 100% tuna.

The exact composition of Subway’s tuna is unclear, as the company has not released any information about their suppliers or preparation methods. Some Subway employees have reported that the tuna comes in a pressed, vacuum-sealed slab that is soaked in salt water. Others have claimed that it’s flaky and mixed with mayo.

It’s worth noting that the quality and freshness of the tuna can vary depending on the supplier and preparation method. If Subway’s tuna does not contain any actual tuna, this could have implications for the entire canned tuna industry. It raises questions about what other types of fish or meats could be present in canned tuna products sold in grocery stores.

As of now, the lawsuit against Subway is ongoing and it remains to be seen what the final outcome will be. However, it’s important for consumers to be aware of the potential issues with Subway’s tuna and to follow food safety guidelines when consuming any type of seafood.

Factors That Affect Tuna’s Shelf Life

There are several factors that can affect the shelf life of tuna, including:

1. Other ingredients: If the tuna recipe contains other perishable ingredients like mayo, their shelf life will also impact the shelf life of tuna. Tuna fish with mayo can remain good for 3 to 4 days. Tuna with any type of pasta is good only for only 4 days. Tuna with egg can last for 5 days.

2. Container rigidity: Whether you use a plastic or glass container, if it is not rigid enough, it will not be airtight, resulting in varying temperatures. Thus, even the best quality tuna will get spoilt when stored in such a container.

3. Processing methods: The processing method used to prepare the tuna can also affect its shelf life. Canned tuna, for example, has a longer shelf life than fresh tuna.

4. Storage temperature: Tuna should be stored at a temperature of 4°C or below to prevent bacterial growth.

5. Quality of the tuna: The freshness and quality of the tuna can vary depending on the supplier and how it’s prepared. Factors such as days of onboard storage, months of the year, whether the catch was living or dead, fish weight and year can all affect the quality of the tuna.

By taking these factors into consideration and following proper food safety guidelines, you can ensure that your tuna stays fresh and safe to eat for as long as possible.

How To Store Your Subway Tuna Sandwich

If you’re not able to finish your Subway tuna sandwich in one sitting, it’s important to properly store it to ensure its freshness and safety. The best way to store your sandwich is by placing it in an airtight container or wrapping it tightly with plastic wrap. Oxygen is the enemy when it comes to preserving food, so make sure to use the smallest container possible and press the plastic wrap directly on top of the tuna to prevent it from drying out.

Once your sandwich is properly stored, it can last for up to three days in the refrigerator. It’s important to note that the longer the sandwich is stored, the higher the risk of bacteria growth and potential foodborne illnesses. So, it’s best to consume your sandwich as soon as possible or within a day or two of purchase.

Signs Your Tuna Sandwich Has Gone Bad

It’s essential to recognize the signs of spoiled tuna to avoid any health risks. One of the most obvious signs is a change in appearance. If you notice any green, brown, or dark spots or signs of mold on your tuna sandwich, it’s best to discard it without tasting it. Discoloration is a clear indication that the tuna has gone bad and should not be consumed.

Another sign of spoiled tuna is an unpleasant odor. Tuna has a naturally strong smell, but if it smells pungent and unappetizing, it’s a sign that the tuna has gone bad. Even if there’s no discoloration or off smell, if your tuna sandwich has been sitting in the fridge for more than four days, it’s best to toss it out.

It’s also important to note that bacteria grow rapidly at temperatures between 40°F and 140°F. If your tuna sandwich has been left out at room temperature for more than two hours (or one hour when it’s really hot out), it’s no longer safe to consume.

In addition to these signs, if you taste your tuna sandwich and notice an off taste or texture, it’s best to discard it. Some ingredients in the sandwich can cause it to lose quality rapidly, so use your judgment when deciding whether or not to consume it.
