Texture
The surface should feel firm and slightly moist. If it feels slimy, sticky, or tacky, bacteria may be present.
Date and storage time
Check the expiration or “use by” date and consider how long the steak has been stored. Even if it looks acceptable, meat kept too long should be discarded.
Clear Signs the Steak Has Spoiled
Beyond turning gray, these indicators mean the steak should not be eaten:
Strong, unpleasant odor
Slimy or unusually sticky surface
Green, yellow, or iridescent patches
Excessive moisture pooling in the packaging
