Iodine is an essential micronutrient required for normal body growth and mental development and an essential element for human survival. Hence Iodine Deficiency Disorder (IDD) has been identified all over the world as a serious threat. In our country, it is estimated that more than 200 million people are at the risk of IDD, while the number of persons suffering from goiter and other iodine deficiency disorder is above 71 million (Govt. of India's guideline for NIDDCP). The main factor responsible for the development of IDD is low dietary supply of iodine in the natural foods. All crops grown on soils that are iodine deficient will be iodine deficient. Iodine deficiency is therefore a deficiency which can affect rich and poors alike, because it depends on the geophysical properties of the land. However consumption of iodized salt can prevent the occurrence of IDD. After successful trial of iodized salt in Kangara valley, Himachal Pradesh in 1962, the Government of India launched a fully centrally sponsored National Goiter Control Programme (NGCP). The main focus was on provision of iodated salt and to identify the endemic areas. The nomenclature of the NGCP was redesigned in 1992 as National Iodine Deficiency Disorder Control Programme (NIDDCP) to emphasize on the wider implication of iodine deficiency.
