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.
If there are obvious signs of spoilage, we recommend that cans or jars not be opened or handled. They should be carefully discarded. If the container is opened and there are signs of spoilage, it should not be consumed. The bulging can and spurting juice were signs that spoilage of some type has occurred inside the container. It is likely that this can has been stored somewhere hot for some time and set off bacteria growth in the cans. There should be contact information for the food processor on the container. They may have further information about the product and what might have happened. If you do start feeling ill, be sure to check with your physician. In the future, I would not open or sample any containers that show signs of spoilage.
