Does added iodine in food need to be declared on the ingredients list USA?

In the United States, the Food and Drug Administration (FDA) requires that all food labels list any added iodine, regardless of the amount. This includes iodine added to foods like bread, milk, and salt, as well as iodine-containing ingredients such as iodized salt and kelp. The FDA also requires that the amount of iodine be listed on the label in micrograms (µg) per serving.
