🥫 Spoiled Canned Tomatoes
Canned tomatoes are shelf-stable, but they can spoil, especially if the can is damaged or improperly stored. Eating spoiled canned food can cause serious illness, so it’s important to know the warning signs.
⚠️ Signs Canned Tomatoes Are Spoiled
1️⃣ Bulging or Swollen Can
- The lid or bottom is puffed out.
- This can indicate gas buildup from bacterial growth.
2️⃣ Leaking or Rusted Can
- Deep rust, dents along seams, or leaks increase contamination risk.
3️⃣ Foul Odor
- Sour, rotten, or metallic smell when opened.
4️⃣ Mold
- Visible fuzzy spots (white, green, black).
- Mold inside means discard immediately.
5️⃣ Unusual Texture
- Excessive foaming, bubbling, or extreme discoloration.
🦠 Botulism Risk
Improperly processed canned foods can develop Clostridium botulinum, which causes botulism — a rare but serious illness.
Warning signs include:
- Bulging cans
- Spurting liquid upon opening
- No smell but visible abnormal pressure
👉 If in doubt, throw it out. Do not taste to test.
🗓️ Shelf Life
- Unopened canned tomatoes: 12–18 months (often safe beyond “best by” date if can is intact).
- Once opened: Store in an airtight container in the refrigerator and use within 5–7 days.
🧊 Storage Tips
- Store in a cool, dry place.
- Avoid extreme heat or freezing.
- Rotate pantry items (first in, first out).
