Three common forms of botulism are:

• Foodborne botulism. The harmful bacteria thrive and make the toxin in environments with little oxygen, such as in home-canned food.
• Wound botulism. If these bacteria get into a cut, they can cause a dangerous infection that makes the toxin.
• Infant botulism.
