Iodine content of rice (42) and drinking water (108) from a goitre-endemic
belt of Assam, a sub-Himalayan zone of India, was evaluated. Iodine content
of staple food (rice) and drinking water was found to be poor. Mean iodine
content of rice was found to be 11.8 +/- 7.3 mu g/100 g. Lower level of io
dine was also observed in drinking water samples (mean of 1.52 +/- 0.48 mu
g/l).
