What food causes botulism?

Does microwaves kill botulism?
desinfectants? Botulinum toxin breaks down at high enough temperatures. “While the botulinum spores can survive in boiling water, the botulinum toxin is heat-labile. Heating food to a typical cooking temperature of 80°C (176°F) for 10 minutes before consumption can greatly reduce the risk of illness.”
