Botulism produces a neuroparalytic illness from inhibition of acetylcholine release at neuromuscular junctions, so weakness starts in the cranial nerves and descends. Early, classic signs are cranial nerve palsies such as double vision, slurred speech, and difficulty swallowing. While some people with foodborne botulism may have gastrointestinal symptoms like nausea or abdominal cramps, true skeletal muscle cramps are not a typical feature of this toxin’s effect. Because the other signs listed align with the neuromuscular impact of botulinum toxin, the symptom that does not fit is muscle cramps. In practice, recognizing the cranial nerve symptoms quickly is important for timely treatment.
