Tomato torpedo, the can had a bulge should I still indulge?

Q: I recently got a can of tomatoes from a food pantry. It was noticeably swollen on both ends. When I punctured it with a can-opener, the juice sprayed 2 feet up in the air. I have never had an experience like this with any canned food product. The tomato juice on my hand tasted fine. Was the pressure build-up in the can an indication of any dangerous condition? Botulism? Or something else? Please advise me if you think it is safe to eat the tomatoes.

Left-out leftovers, leave them?

Q: We made frozen pizza for dinner last night. Unfortunately, we then settled down for a long winter's nap and forgot to put the leftover pizza and a bottle of ranch dressing away in the fridge. Both sat on the counter overnight. My husband put both in the fridge this morning and thinks "they'll be fine." I think not. Who is right?
