Several public health agencies in the United States provide clinical consultation and antitoxin, when indicated, for suspected cases of botulism. They are:

Botulism case consultations provide expert guidance to clinicians. Consultations also facilitate the collection of information for all suspected botulism cases reported in the United States.
