Iodination - the need to enforce quality assurance

Abstract

The Medical Research Institute (MRI) helped by the WHO, has monitored the effects of iodination by conducting surveys on school children nationwide every five years (1 4) beginning from 20002001. The requirement of iodine (as iodate) at consumer level was brought down from 25 ppm at the beginning to 15 ppm in 2005, as surveys monitoring urinary iodine content in the sampled children, showed a median concentrations above the target level 100 mg/L.
