Is potassium iodate a poison?
Answer Potassium iodate is totally safe in quantity consumed. The average salt consumption in India is 10 g per capita per day. At the manufacturing level 50 ppm (50 mg per kg of salt) of KIO3 is added. Consumption of 10 g of iodised salt will provide a maximum of 500 mcg of KIO3. This quantity is 60,000 times less than lethal dose low of KIO3.
