Metal contamination of foods is emerging as a major health hazard to the consumers. Ingestion is the major route for the entry of toxic metals into human body. Research has been done on the metal contamination of conventionally grown raw as well as cooked foods hence the present study aimed to determine the metal content of organically grown foods as organic foods claim to have least artificial inputs. Organic food samples collected from organic food outlets of Vadodara city, prepared by market basket method were digested using wet digestion method. A total of (20 raw, 35 pre treated and 38 cooked food samples were analysed for Al, Cd, Ni, Pb, Zn, Cu, Cr, Fe, Se using AAS. Pre treatments resulted in considerable reduction in almost all the metals except Al and Fe. The results of metal content of raw foods showed that Cu, Fe, Zn, Ni and Pb were below the safe limits given by FAO WHO 2001 while Cd exceeded the safe limit of 0.2 µg/g. Health risk was associated with the consumption of Cd and Ni from the intake of cooked organic foods analyzed as they exceeded the safe intake limits given by JECFA.
