How do you prevent botulism?

Botulism. Botulism usually occurs when you ingest contaminated canned food. Person to person transmission of botulism does not occur. Make sure that any canned food you eat has not expired. Also, avoid feeding honey to infants (infant botulism).
Be careful. Botulism is quite uncommon and occurs when spoiled food is consumed. Clostridium botulinum is the offending bacteria but it is the consumption of the bacterial toxin that causes illness. Avoid eating any spoiled foods or canned food which appear bulging.
