In the world of canned goods, tuna is a staple that many people rely on for quick and easy meals. Whether you enjoy it in a salad, sandwich, or casserole, tuna is a versatile protein that can be a lifesaver on busy days. However, like all foods, tuna does have an expiration date, and knowing how to properly store and use it can help you avoid any potential health risks.

Understanding Tuna Shelf Life

Tuna, whether canned or fresh, has a limited shelf life. Here are some key points to keep in mind when it comes to the expiration of tuna:

Canned Tuna Expiration

Canned tuna typically has a shelf life of 2-5 years, depending on the packaging and storage conditions.
Check the expiration date on the can before consuming the tuna.
Canned tuna can still be safe to eat after the expiration date if the can is undamaged and properly stored.

Fresh Tuna Expiration

Fresh tuna should be consumed within 1-2 days of purchase.
Store fresh tuna in the refrigerator at a temperature below 40°F (4°C) to maintain freshness.
If fresh tuna has a strong fishy odor or slimy texture, it is best to discard it.
