Thanks. So, if the can is not damaged, one can reasonably infer that this particular problem is not present?

I'm not sure. Probably would depend on what the food is, water content and how hard it froze.

Canned nuts would be pretty safe because of their low water content.

I would think that if the can froze and contents expanded enough to damage can it would be noticeable.

Best just to keep your supplies from freezing.
