Denmark introduced mandatory iodisation of table salt in 2000. Results of this were significant, with a national decrease in prevalence of goitre, nodules and thyroid dysfunction.Recent studies have shown that pregnant women and their fetuses are particularly vulnerable to iodine deficiency and Danish Public Health aims to intervene to improve iodine status in these groups. Therefore from 1st July 2019, the requirement for the iodine concentration of iodised salt increased from 13 mg/kg to 20 mg/kg.
We look forward for future data on the impact of this intervention
