Jamaican vomiting sickness: a study of two adult cases

An acute illness (Jamaican vomiting sickness) which affected two adults after eating unripe ackee fruit was investigated. Analyses of serum and urine samples were performed to compare the patterns of organic acidaemia and aciduria with those reported from childhood cases. The main conclusion from the comparison is that the toxic ackee constitutent, hypoglycin, produces essentially the same metabolic effects in adults as in children.
