Consuming expired applesauce can pose health risks due to the growth of microorganisms and the production of toxins. Specific microorganisms, such as Clostridium botulinum, may thrive in expired applesauce and produce botulinum toxin, causing severe symptoms like muscle weakness and respiratory paralysis. It’s crucial to adhere to food safety measures, including proper storage, handling, and timely consumption of perishable foods like applesauce, to prevent foodborne illness and its potential consequences.
