[Objective]To understand the iodine content in salt of households, and evaluate the implementation of the measure of salt iodization to eliminate IDD, so as to provide scientific basis for further prevention of IDD. [Methods]Analy- sis was made on the iodine salt surveillance of households from 2006-2011. [Results]From 2006 to 2011 ,a total of 19 058 household salt samples were monitored,Iodized salt was 18 840 and it covered 98. 86% ,the average iodine content in salt was 30.78 mg/kg;218 were non-iodized salt,the coverage rate of iodized salt was 98.86% ,the rate of non-iodized salt was 1.14%;18 699 were qualified,the rate of qualified iodized salt was 99.25%, the rate of eating qualified iodized salt was 98.12 %. The rate of qualified iodized salt was 99.39 %, 99.06 %, 99.06 %, 99.22 %, 99.04 % and 99.80 % respectively during 2006-2011. The rate of eating qualified iodized salt was 97.67% ,97.81% ,97.81%0,97.65% ,98.42% and 99.46% respectively. Shahekou district （ 100.00 % ）, Development district （ 10G 00 % ）, Zhongshan district （ 99.94 % ） had relatively higher coverage rate of iodized salt,and the rate of eating qualified iodized salt was 99.83% ,99.75% and 99.94% respec- tively. [Conclusion]The quality of iodized salt is satisfactory, the coverage rate of iodized salt and the rate of eating quali- fied iodized salt are increasing year by year in Dalian city.
