It is understood that the highest iodine content of salt in the original national standard is 60 mg/kg. According to actual calculations, the actual iodine content in the country currently is generally 30 mg/kg, which is consistent with the revised upper limit of iodine content. According to the discussion draft of the relevant guidance presented at the meeting, provinces (autonomous regions and municipalities) can supply ** according to the three types of situations: the qualified ** consumption rate of the residents is greater than 90% and the median urinary iodine is from 100 μg/L to 200 μg. In the area of ​​liter/liter, the ** concentration can be selected as 30 mg/kg; the eligible ** consumption rate is greater than 90%; the median urinary iodine is in the range of 200 micrograms/liter to 300 micrograms/liter, and ** concentration can be selected as 25 mg /kg; ** concentration of 20 mg/kg may be selected in areas where the resident ** consumption rate is greater than 90% and the median urinary iodine is above 300 mcg/L.
Wang Bin, deputy director of the Department of Disease Control of the Ministry of Health, said at the meeting that the salt iodine supplement strategy will not waver in the future, and will continue to supply qualified ** in areas that have met the criteria for eliminating iodine deficiency disorders; In the regions, to further strengthen the popularity of **, to increase the coverage of ** and qualified ** consumption rate; in areas where iodine deficiency disorders are still prevalent, monitoring and early warning can be used to promptly take emergency measures to supplement iodine for high-risk groups. According to Liu Shoujun, director of the Iodine Deficiency Disorder Research Institute at the National Center for Disease Control and Prevention of the China Center for Disease Control and Prevention, special needs groups such as pregnant women and breastfeeding women should consume 30 mg/kg to ensure demand.
