[Objective] To understand the current status of iodine content of household salt in 2007 in Longgang District, Shenzhen. [Method] A total of 367 edible salt samples from 9 third grade primary school students in 9 streets in 9 districts of the district were randomly selected. Salt iodine content was determined by direct titration in GB / T13025.7 ~ 1999. [Results] The qualified iodized salt consumption rate was 77.4%, unqualified iodized salt consumption rate was 7%, non-iodized salt consumption rate was 15.2%. [Conclusion] The monitoring data showed that the salt iodine consumption rate of residents in Longgang district in Shenzhen was lower in 2007, and that all residents in 9 towns (streets) consumed non-iodized salt, which should be paid great attention by the government and the salt industry department. We will strengthen the supply and management of iodized salt to residents, further increase the inspection of non-iodized salt and educate the masses on the identification of iodized salt.
