Abstract(s)

Iodine is an essential trace element in human and animal diets. However iodine deficiency is reported in most of the countries. Food is the natural source of iodine. Traceable analytical values to SI units are required to guarantee reliable measurement results which are used to estimate iodine intake overtime at national and international level. The aim of this study was to create an iodine database containing analytical values, methods of analysis and metrological concepts, described in scientific publications reporting food data. This database will be used as a starting tool to define the iodine key foods as part of national diet programme.
