Why does soup spoil?

Answer 1

Canned products have been sealed in a sterile environment. They can be eaten beyond their best before date, though after this date they are likely to have deteriorated in flavour or texture, however they should not go bad/mouldy. Only fresh foods have a 'Use By' date which indicates the food is likely to go bad if not eaten by a certain date.

Be aware however that cans which have been dented could cause the soup to go bad due to damage to the seals/surface allowing air to get in. Also cans which are rusty or bulging are likely to be unsafe to eat.

Answer 2

There could be several reasons, but the main one would be that spoilage microorganisms have grown in the soup. Either the soup became contaminated or it was not heated and cooled properly or it is too old.

Answer 3

Soup spoils because of mold or bacterial growth. Refrigeration does not prevent spoilage, it only delays it.

Answer 4

Yes. Keep it refrigerated and use is within a few days.

Answer 5

Yes. Bean soup does need to be stored under refrigeration.

Answer 6

Yes. Soup has a high water activity which would make it perishable. If it is properly canned, it can become shelf stable.

Answer 7

Yes, it can. Soup should be thrown out after no longer than three days of refrigeration.

Answer 8

Yes, soup can spoil if left sitting out for over two hours. If refrigerated, soup should be thrown out after three days at the most.
