Featured Question

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.
