Pantry
12-18 months (unopened)
Store unopened cans in a cool, dry place, away from direct sunlight and heat. Do not store above 75°F (24°C).
Refrigerator

Once opened, transfer stewed tomatoes to a clean, airtight container. Do not store in the opened can.

Transfer stewed tomatoes to freezer-safe containers or heavy-duty freezer bags. Leave headspace if using rigid containers, as liquids expand when frozen.
Signs of Spoilage
- Off-odor (sour, yeasty, or fermented smell)
- Mold growth on the surface
- Discoloration or darkening
- Fuzzy appearance
- Bulging or leaking cans (for unopened product, indicates spoilage and should be discarded immediately)
Room Temperature Safety
The 'Danger Zone' for food is between 40°F (4°C) and 140°F (60°C), where bacteria can multiply rapidly.
Stewed tomatoes, once opened, should be refrigerated promptly. If left at room temperature within the danger zone for too long, discard them.
Safe Handling
Always wash hands with soap and water before and after handling food.
Inspect unopened cans for damage such as bulging, leaks, or deep dents. Discard any damaged cans.
Once opened, promptly refrigerate any unused portions.
Avoid cross-contamination by using clean utensils and containers.
