Signs of Spoilage
- Off-odor (unpleasant, sour, or overly fishy smell)
- Slimy or sticky texture
- Mold growth
- Discoloration
- Bulging, leaking, or severely dented cans (for unopened product)
Room Temperature Safety
40°F–140°F
Opened canned sardines should not be left at room temperature for more than 2 hours. If the ambient temperature is above 90°F (32°C), they should not be left out for more than 1 hour.
Safe Handling
Always check cans for damage before opening. Discard cans that are bulging, leaking, or severely dented, as these can be signs of spoilage.
Once opened, promptly transfer any unused sardines to a clean, airtight container and refrigerate.
Do not consume if there are any signs of spoilage, regardless of the storage duration.
