This article describes a case report on a rare cause of acute respiratory failure. The patient suffered from a rapidly progressing respiratory insufficiency due to intoxication with a neurotoxin (botulism). A rapid diagnosis proved to be very difficult due to the rarity of the disease itself and the difficulties encountered in the clinical examination caused by early initiation of intubation, artificial ventilation and analgosedation.
