摘　　要：目的了解盐业体制改革3年后,贵州省市场食盐销售情况及盐碘含量。方法2020年8-10月,在贵州省9个市(州),每个市(州)选择2个县(市、区),每个县(市、区)选择1个城区和1个乡镇,在城区抽取1家大型超市和1个农贸市场,乡镇抽取1家小型超市或便利店,查看销售食盐的品种、产地、包装上碘含量标识,并采集不同品牌食盐同时送省、县级疾病预防控制中心盐碘实验室测定其碘含量并进行分析。结果共调查18家大型超市和18个农贸市场、18个乡镇小超市或便利店,采集23个品牌、3大种类、产地来自11个省份的食盐70份。其中包装上碘含量标识为21~39 mg/kg的有56份,省级检测其碘含量范围为19.23~37.41 mg/kg(其中有2份低于21.0 mg/kg),中位数为25.75 mg/kg;包装上标识两种碘含量(18~33、21~39 mg/kg)的有12份,省级检测盐碘范围为23.52~32.90 mg/kg,中位数为26.55 mg/kg;1份标识为18~33 mg/kg,省级检测碘含量为25.20 mg/kg;1份标识为未加碘食盐,其碘含量未检出。根据实际检测值,有68份销售食盐的碘含量在包装标识范围内,占总份数的97.14%。以省级检测结果为标准,省、县级实验室检测结果相对偏差绝对值范围为0~27.45%,平均偏差为7.65%,符合率为91.43%(66/70)。结论盐业体制改革3年后,贵州省市场销售食盐跨省经营多,品种齐全,97%以上的抽检样在贵州省执行的食盐碘含量标准范围内。Objective To understand the salt sales situation and salt iodine content in the market of Guizhou Province 3 years after the system reform of salt industry.Methods From August to October 2020,in 9 cities(prefectures)of Guizhou Province,2 counties(cities and districts)were selected from each city(prefecture),1 urban area and 1 township were selected from each county(city and district),1 large supermarket and 1 farmers'market were selected in the urban area,and 1 small supermarkets or convenience stores were selected in the township,to check the varieties,place of origin and iodine content label on the package of salt sold,and different brands of salt were collected and sent to the provincial and county salt iodine laboratories.The iodine content was determined and analyzed.Results A total of 18 large supermarkets,18 farmers'markets and 18 small supermarkets or convenience stores were investigated,and 70 salt samples of 23 brands,3 types and origin from 11 provinces were collected.Among them,there were 56 samples with iodine content of 21-39 mg/kg on the package.The iodine content range of provincial detection was 19.23-37.41 mg/kg(two of them were lower than 21.0 mg/kg),and the median was 25.75 mg/kg.There were 12 samples of two iodine contents(18-33 and 21-39 mg/kg)marked on the package,and the salt iodine range of provincial detection was 23.52-32.90 mg/kg,with a median of 26.55 mg/kg.One sample was marked with 18-33 mg/kg,and the iodine content of provincial detection was 25.20 mg/kg;the iodine content of 1 sample of non-iodized salt was not detected.According to the actual test value,iodine contents of 68 samples were within the range of packaging marks,accounting for 97.14% of the total.Taking the provincial test results as a standard,the absolute value of the relative deviation of the provincial and county test results was 0-27.45%,the average deviation was 7.65%,and the coincidence rate was 91.43%(66/70).The county test results were acceptable.Conclusions After the system reform of salt industry,there are m
