Does all honey contain botulism?
Honey is one of the most common causes of botulism. Approximately 20% of botulism cases involve honey or corn syrup. One 2018 study examined 240 samples of multifloral honey from Poland. Researchers found that 2.1% of the samples contained bacteria involved in the production of botulinum neurotoxin.
What is the difference between food poisoning and botulism?
Botulism is a disease caused by a bacterium scientifically known as botulinum. Botulism occurs when the toxin produced by botulism is consumed in improperly stored foods. The disease is caused by a potent neurotoxin produced by the bacteria.
Why is botulism so rare?
Bacteria that produce botulinum toxin are found naturally in many places, but they seldom make people sick. These bacteria produce spores that act like a protective coating. The spores help the bacteria survive in the environment even under extreme conditions.
