Abstract One of the food intoxications encountered in Turkey is the case 
caused by toxic honey made by bees fromRhododendron species.R.luteum 
andR.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 ofRhododendron leaves.
