Which term matches the definition: Rare but serious illness caused by a toxin that attacks the body's nerves.

• A. Nutrition
• B. Botulism
• C. Calories (energy)
• D. Organic food

Answer: (B)

A toxin that attacks the nerves describes botulism. Botulism comes from the botulinum toxin, which disrupts nerve signals by preventing the release of acetylcholine at the neuromuscular junction. That disruption leads to weakness and, in severe cases, paralysis that can affect breathing, making it a rare but serious illness. Preventing it is a matter of safe food handling and preparation—proper canning, avoiding damaged or bulging cans, heating foods to safe temperatures, and, for infants, avoiding honey to prevent infant botulism. This term isn’t about food labels or energy in the body—nutrition describes nutrients, calories are units of energy in food, and organic food refers to a production method—so botulism is the disease most specifically matching the definition.
