I've always been told that if you see air bubbles in canned food, you should treat it like toxic waste. Today I opened a can of tomatoes and saw a few air bubbles form along the edges of the can. Is this what I was warned about? Or are they talking about food that looks like it's fizzing or oozing out of the can?
Here's a picture. There were ~2-3x that many bubbles when I first opened the can.
- I didn't notice whether there was a sound of air escaping when I opened the can. It was noisy in the room.
- The can hadn't been extensively shaken or agitated before opening.
- If it's hard to tell from the picture, that's enough of an answer for me. I just want to know whether this even remotely resembles what the "air bubbles" warning is talking about, or if it's totally unrelated.
