But, how long does tuna fish last and what is the best way to store it? In this article, we will answer those questions and provide you with tips on how to enjoy fresh and delicious tuna for as long as possible.
Is Tuna Perishable?
Tuna, like all fish, is a perishable food item. That means it can spoil quickly if not handled and stored properly. Fresh tuna should be refrigerated or frozen immediately after purchase. For tuna that is canned and shelf-stable, it can be stored at room temperature as long as it is not opened.
How Long Does Tuna Fish Last?
Fresh tuna that is stored properly in the refrigerator can last up to 3 days, while frozen tuna can last up to 6 months. Canned tuna that is unopened can last up to 2 years, while opened canned tuna can last up to 3-5 days. As tuna is an oily fish, it is more prone to spoilage than other types of fish.
How to Tell if Tuna is Spoiled?
The best way to tell if tuna is spoiled is by its smell and appearance. Fresh tuna should have a mild, ocean-like smell and its flesh should be firm. If it has a strong, fishy smell or its flesh is soft and discolored, it is likely spoiled and should be discarded.
