Clostridium botulinum is a strict anaerobe; that is, it is killed by the molecular oxygen (O2) present in air. Humans can die of botulism from eating foods in which C. botulism is growing. How does this bacterium survive on plants picked for human consumption? Why are home-canned foods most often the source of botulism?
