Expiration & Storage Tips
When does tuna expire?
Canned tuna is safe to consume 2-5 years past its printed expiry date if unopened and stored in a cool and dry place. However, once opened, the leftovers should be refrigerated and consumed within 3-4 days. Fresh tuna, on the other hand, should usually be consumed within 2 days of purchase. If frozen, it stays safe indefinitely, but for best quality, consume it within 2-3 months.
How do you tell if tuna is bad?
To tell whether canned tuna has gone bad, look for bulges or leaks in the can. This could be a sign of bacterial activity. If you’ve already opened the can, a foul or fishy smell, a change in color or texture, or any mold growth all suggest that the tuna might be spoiled. Similarly, with fresh or frozen tuna, any strong offensive smelly, discolored spots or slimy surface indicates spoilage.
Tips for storing tuna to extend shelf life
• Always refrigerate fresh tuna immediately after purchase. Using a fridge thermometer can help ensure that your fridge is at the recommended storage temperature of 4°C (40°F).
• If you can't consume fresh tuna within two days of purchase, freeze it. Before freezing, tightly wrap the piece in a plastic wrap and squeeze out any air pockets to avoid freezer burn.
• Keep canned tuna in a cool and dry place like your pantry, away from heat or moisture.
• After opening canned tuna, transfer any leftovers to a sealed container before refrigerating.
• Remember to defrost frozen tuna in the fridge overnight, not at room temperature to avoid bacteria growth.
