Expiration & Storage Tips
When does fresh tuna steak expire?
Unopened fresh tuna steak usually lasts for 1-2 days in the refrigerator. However, the 'use-by' date on the package is the best indicator for fresh packaged tuna steak. Once it's opened, it's best to use within a day. If frozen properly, a fresh tuna steak can maintain its quality for 2-3 months.
How do you tell if fresh tuna steak is bad?
The easiest way to tell if your tuna steak has gone bad is to sniff it. Everyone's familiar with the fresh, mild, ocean-like aroma of good fish. But when it turns bad, it'll have a strong, sharp smell that's rather unpleasant. In addition, if its firm texture turns mushy or if it has a dull, darkened color, then it is most likely bad and should not be consumed.
Tips for storing fresh tuna steak to extend shelf life
• Wrap the tuna steak tightly in plastic wrap and refrigerate it as soon as possible. If you can't eat it right away, freeze the tuna while it's still fresh.
• For freezing, wrap the tuna steaks tightly in plastic wrap, then in aluminum foil before placing in a freezer-safe bag.
• Ideally, fresh tuna should be eaten within 24 hours. Always remember to keep it at the coldest part of your refrigerator.
• When thawing frozen tuna, do so in the refrigerator or in cold water to maintain its texture and prevent it from drying out.
• If you've marinated the tuna, don't keep it for more than 24 hours. As a rule of thumb, the acid in the marinade can start to 'cook' the tuna and alter its texture.
