🫧 Why There Are Bubbles

Bubbles in canned food after opening can mean:

• Bacterial spoilage

• Gas produced inside the can

• Unintended fermentation

• Loss of seal or contamination

In canned foods, fermentation = spoilage. Unlike controlled fermentation (like yogurt or pickles), canned tomatoes are not supposed to ferment. If they are bubbling, something has gone wrong.

⚠️ Other Warning Signs to Check

Throw the can away if you notice:

• Sour, alcoholic, or “off” smell

• Foam or fizzing

• Bulging or dented can

• Liquid spurting when opened

• Mold or unusual color

• Slimy texture

🚫 Important Safety Note

Do not taste tomatoes from a bubbling can. Some foodborne bacteria can be dangerous even in small amounts, and you can’t always smell or see them clearly.

✅ What To Do

• Don’t use it

• Seal it in a bag and discard it

• Wash your hands and any surfaces it touched

If you want, you can tell me whether the can was bulging, dented, or expired — I can help you judge the risk level more precisely.
