Botulism is a rare cause of neuroparalysis. Delay in diagnosis and treatment exerts adverse impact on mortality and morbidity. We report a child with complete flaccid paralysis followed by progression to coma-like consciousness. The patient required mechanical ventilation. As serological tests could not be performed, detailed history and physical examinations led to the suspicion of botulism, and repetitive nerve stimulation tests supported the diagnosis. Botulinum antitoxin was administered. The patient's neuromuscular function improved rapidly.
