NREMT Paramedic

Answer: C - Clostridium botulinum is an anaerobic, gram-positive, spore-forming bacterium that produces neurotoxin. Onset of symptoms, including paralysis, is usually 18 to 36 hours after ingestion of toxin-containing food. Exposure is usually due to improper food storage, particularly canning. Early common signs include a marked lassitude, weakness, vertigo, difficulty speaking and swallowing, difficulty breathing, muscle weakness, abdominal distention, and constipation.
