Why is botulism associated with potatoes?
If a low-acid food such as potato soup is stored unrefrigerated in an anaerobic environment (e.g., a sealed container), without a barrier to bacterial growth, spores can germinate, resulting in bacterial growth and botulinum toxin production (2).
Can potatoes cause botulism?
Perhaps the most concerning consequence of cooling a baked potato improperly is the potential growth of Clostridium botulinum, which is a group of bacteria that can cause botulism. Botulism is a serious illness that can lead to paralysis and even death if left untreated.
What bacteria grows on potatoes?
Soft rot bacteria, arguably the most important potato pathogen known, are facultative anaerobes. Bacteria of the genera Pectobacterium (formerly Erwinia), and Dickeya (responsible for causing seed piece decay), blackleg, stem soft rot, as well as extensive storage losses, are members of this group.
