Survey on cadmium content in thirty samples of black tiger prawn (Penaeus monodon) from cultivating area in the upper Gulf of Thailand during August 1990 to September 1991 had been conducted. The prawn samples were separated into whole peeled tail-off, whole peeled tail-off and deveined, headless peeled tail-off and deveined, head and vein and then analyzed for cadmium content by atomic absorption spectrophotometry with background corrector and dry-ashing technic for sample digestion procedure. The results showed average cadmium content 0.23, 0.20, 0.08, 0.83 and 0.93 mg/kg. Estimated dietary intake for edible portions (not including vein) were 46, 36, 11.2 and 33.2 micro g per day for Thais. These were well within the provisional average dietary intake of cadmium of 10-50 micro g per day proposed by the Joint FAO/WHO Expert Committee on Food Additives.
