碘化食盐是防治缺碘性地甲病和地方性克汀病的根本措施。但有些地区和国家不能销售碘盐,或因制订的法律和防治计划尚不能落实,以及碘盐在加工技术、包装、销售、运输等方面还有一些问题未解决,以致使推广碘盐具有一定困难或不能保证碘盐的质量。因而,近年来许多国家用碘油来弥补上述的不足。 Iodized salt is a fundamental measure to prevent and treat iodine deficiency and endemic cretinism. However, some regions and countries can not sell iodized salt, or the law and prevention and control plan can not be implemented yet, and there are still some problems in the processing technology, packaging, sales and transportation of iodized salt that have not yet been solved, thus promoting the promotion of iodized salt Difficult or not guaranteed quality of iodized salt. Therefore, in recent years, many countries use iodized oil to make up the above deficiencies.
