Does the fridge kill botulism?
botulinum while growing in foods. These rod-shaped bacteria grow best under anaerobic (or, low oxygen), low-salt, and low-acid conditions. Bacterial growth is inhibited by refrigeration below 4° C., heating above 121° C, and high water-activity or acidity. And although the toxin is destroyed by heating to 85° C.
