How long is tuna cups good for?

It's difficult to give a precise answer without knowing more about the specific tuna cups you're asking about. Here's what I need to know:

* Type of tuna: Is it canned tuna in oil, water, or brine? Is it packed in a pouch or a can?

* Storage conditions: Are they refrigerated, at room temperature, or frozen?

* Expiration date: Does the container have an expiration date printed on it?

Here's a general guideline:

* Canned tuna: Canned tuna (in oil, water, or brine) is generally good for 2 to 5 years after the "best by" date if stored unopened in a cool, dark place.

* Tuna pouches: These typically have a shorter shelf life, usually between 6 to 12 months. Look for the "best by" or "use by" date on the packaging.

* Refrigerated tuna cups: If you're asking about pre-made tuna salad cups, the "use by" date should be followed. Once opened, they should be refrigerated and used within 3 to 5 days.

* Frozen tuna cups: If you freeze pre-made tuna salad cups, they can typically last for 2 to 3 months.

Important Note:

* Always check the expiration date on the packaging. This is the most accurate indicator of the product's freshness.

* Look for any signs of spoilage such as discoloration, mold, or an off-smell. If you see any of these, don't eat the tuna.

If you have any concerns about the freshness of your tuna, it's best to err on the side of caution and throw it away.
