Lupin seeds can contain toxicologically significant bitter quinolizidine alkaloids, which may induce symptoms of poisoning in humans by affecting the nervous, circulatory, and digestive systems. Typical manifestations of lupin alkaloid poisoning include dizziness, confusion, tachycardia, nausea, dry mouth, loss of motor coordination, and, in severe cases, cardiac arrest and respiratory paralysis. This case report describes accidental poisoning following the ingestion of food contaminated by water previously used to boil dry lupin seeds. An 85-year-old woman consumed meals prepared with this water and subsequently exhibited classic symptoms of gastrointestinal poisoning, requiring urgent admission to the emergency department.
