Final answer:
Madison's paralysis is most likely a result of blocked acetylcholine, which is caused by botulinum toxin found in contaminated food.
Step-by-step explanation:
Madison's paralysis is most likely a result of blocked acetylcholine. Botulinum toxin, which is found in contaminated food, prevents the release of acetylcholine from axon endings at the neuromuscular junction. This causes flaccid paralysis, which is the loss of muscle tone and control.
