Opened a can of Spam and found it sitting in a clear jelly. Is that normal or did it go bad

5. The Smell Test: When the Aroma Means Toss It
Your nose is a powerful tool in determining the freshness of Spam. When you first open a can, the smell should be mild and slightly salty, characteristic of cooked pork products. If you detect any sour, rancid, or otherwise unpleasant odors, this could be a sign that the Spam is no longer safe to eat.
Odor changes are often one of the first signs of spoilage, as bacterial growth can lead to the production of foul-smelling compounds. If the aroma is questionable, it’s better to discard the can than risk consuming spoiled meat.
