Iodine content in the produced and marketed iodized edible salt in Semnan providence, the primary salt-producing province in Iran

Abstract Background: Iodine deficiency represents a significant global public health issue, as it can result in Iodine Deficiency Disorders. Worldwide initiatives have diminished the incidence of these disorders in numerous areas via Universal Salt Iodization. The purpose of this study was to evaluate the iodine content in salt samples manufactured and distributed in Semnan Province, Iran. Methods: A total of 373 salt products, available in markets and produced by factories in the Semnan province of Iran, were collected. The samples were analyzed to determine iodine concentration using a titration instrument, in accordance with the standards of the Iranian National Standardization Organization No. 3696 and Codex Alimentarius. Results: Iodine was found in 86.6% of edible iodized salt samples at a standard concentration, with a mean ± SD of 40.93±12.07 mg/kg. The iodine concentration ranged from a minimum of zero to a maximum of 90.71 mg/kg. Conclusions: The article primarily indicated that the majority of salts produced and marketed in Semnan province contain iodine concentrations within the standard range.
