Abstract:
In response to the recent interest in potassium iodate iodized (KIO 3) salt safety, we reviewed the background of KIO 3 in replacing of potassium iodine (KI) as salt fortificator and its effect in prevention and control of iodine deficiency disorders (IDD) or endemic goiter, the decision-making changes of fortificator of iodized salt in China, the research and progress of toxicology, and whether IO 3- exits in urine without decomposition or not. Our inclusions are: it is believed that the decision of the international organizations and agencies of national and local governments about the safety of KIO 3 in iodized salt is supported by adequate and scientific evidents. When it comes to the safety of KIO 3 added in iodized salt, it must be based on the trace amount of KIO 3 in salt which is limited while intaking. Reductive substances in food, cooking heating or reduction system of human body might quickly reduce trace IO 3- to I -, therefore, IO 3- might not be found in fresh urine.
