Where is botulism commonly found?

Clostridium botulinum is found in soil and untreated water throughout the world. It produces spores that survive in improperly preserved or canned food, where they produce a toxin. When eaten, even tiny amounts of this toxin can lead to severe poisoning.

Can you get botulism from a dented can?

Botulism, caused by the bacteria clostridium botulinum, occurs when a dent or damage to a can creates even a pinhole-size opening. The mixture of air and moisture from the food within the can spurs growth of the bacteria, and the food becomes contaminated. … Dented cans are the biggest culprit of botulism.

The toxin that Clostridium botulinum produces is among the most deadly food toxin known. Fortunately, heat destroys the toxin and cooking is the best way to control botulism.

Why is botulism so rare?

Spores are not killed by boiling, but botulism is uncommon because special, rarely obtained conditions are necessary for botulinum toxin production from C. botulinum spores, including an anaerobic, low-salt, low-acid, low-sugar environment at ambient temperatures.
