Salt always contains bromide as an impurity, at levels high enough so that a bromide nutritional deficiency has never been observed.
This is the reason why it was discovered so late that bromide is also an essential nutrient for animals.
When someone does not eat enough salt, the lack of sodium would cause hyponatremia and eventually death if not treated, long before the development of any symptoms caused by insufficient chloride or bromide or iodide.
