ABSTRACT
Objective To explore the qualification and consuming of iodized salt at wholesale and household levels after Salt Iodization.Methods Iodized salt surveillance at wholesale and household levels every year by detecting iodine content.Direct titration method(GB/T 13025.7-1999)was used for salt iodjne detecting and arbitration method was used for Sichuan salt and special salt.Results Five thousand six hundred and seventy five samples of 227 batches from 3 wholesale industries were detected during 1996-2000,batch qualification rate was 60.79%(138/227)and iodized salt qualification rate was 61.83%(3509/5675).During 2001-2007,2556 samples of 252 batches from wholesale levels were detected.The batch qualification rate and iodized salt qualification rate were 1 00%(252/252)and 99.88%(2553/2556),respectively.At household level.1583 samples from 236 villages were detected during 1996-2000.Iodized salt qualification rate was 74.24%(1 170/1576)and consuming rate of qualified iodized salt was 73.91%(1 170/1583)and iodine median was 45.14 mg/kg.During 2001-2007,13 140 samples from 1656 villages were detected.Iodized salt qualification rate,consuming rate 0f qualified iodized salt and iodine median were 98.03%(12 830/13 088),97.64%(12 830/13 140)and 30.13 mg/kg,respectively. The most difference of iodine content was 3.46 mg/kg in 3 wholesale industries.At household level there was a 4.95%reduction in comparison with at wholesale level.Conclusions Salt iodization level and edible iodine salt reach the national requirements of iodine deficiency control from the starting stage.The quality 0f iodized saIt at household level related to the exclusive wholesale industry and loss phenomenon maybe existed when salt was sold from wholesale industries to residents.
