Poisoning by toxic honey in Turkey

Arch Toxicol. 1993;67(2):148-50. doi: 10.1007/BF01973687.


One of the food intoxications encountered in Turkey is the case caused by toxic honey made by bees from Rhododendron species. R. luteum and R. ponticum are the two species which grow in the north regions of Turkey. Grayanotoxins, mainly Grayanotoxin I (Andromedotoxin) occurring only in Ericaceae plants, are the compounds responsible for poisoning. In this investigation, the diagnosis and treatment of 11 cases of poisoning admitted to Kartal Occupational Diseases Hospital between 1983 and 1988 are presented. The results of the light microscopic and chemical analysis of toxic honey samples are compared with those of the ordinary honey samples and the extract of Rhododendron leaves.
