Answer

In the United States, approximately 154 cases of botulism are reported annually to the Centers for Disease Control and Prevention (CDC). Infant botulism accounts for nearly 75% of all botulism cases.

The incidence of foodborne botulism is approximately 24 cases per year. The incidence of wound botulism is 3 cases per year. The incidence of infant botulism is 71 cases per year, with a mean age of 3 months.

Toxin A is found predominantly west of the Mississippi River. Toxin B is found most commonly in the eastern United States. Toxin E is found in northern latitudes, such as the Pacific Northwest, the Great Lakes region, and Alaska. The frequency of botulism in native Alaskans is among the highest in the world. [3] Toxin E outbreaks are frequently associated with fish products.
