Botulism is generally treated with botulism antitoxin and supportive care. This outbreak of botulism produced the National Botulism Surveillance System. Botulinum toxin produced by "Clostridium botulinum" is the cause of botulism. Botulin is produced by "Clostridium botulinum" and causes the deadly disease botulism. Symptoms of botulism may occur away from the injection site of botulinum toxin. Such bacterial diseases include anthrax, botulism, tetanus, and tuberculosis. Infection with the bacterium causes the disease botulism. Two preparations of botulinum antitoxins are available for treatment of botulism. There are toxoids for prevention of diphtheria, tetanus and botulism. This genus includes several significant human pathogens, including the causative agents of botulism and tetanus. The largest recorded outbreak of foodborne botulism in the United Kingdom occurred in June 1989. This less immunogenic antitoxin is effective against all known strains of botulism where not contraindicated. However, outbreaks of botulism have resulted from more unusual sources. This antitoxin is effective against all known strains of botulism, except for strain H.
