Second-largest salt producing state ranks last in usage of iodised salt; children lose up to 15 IQ points due to iodine deficiency

Tamil Nadu, India's second-largest salt producer, has the lowest share of households using adequately iodised salt, with just 62% meeting the standard against a national average of 76% in a 2018-19 survey. Health officials have raised concerns over iodine deficiency, goitre among schoolchildren and household salt habits, while urging people to consume less than 5g of salt daily.
