The United States and Europe agree that the treatment of botulism is based on symptomatical measures and, notably, on mechanical ventilation when the respiratory function is impaired. Opinions diverge regarding the specific treatment represented by anti-botulinum serum: used systematically in the United States and frequently in many European countries, France never uses it other than in a few cases. Identification of the contaminating foodstuff is a fundamental element in limiting extension of the disease. Reducing the delay in declaration and the identification and correction of bad cooking practices would help to reduce the number of cases of botulism.
