To find out whether iodised edible salt available for sale to the public is iodised, iodination is within the Sri Lanka Standards Institute (SLSI) specifications and the labelling is accurate.
38 packets of iodised salt from 11 different brands were randomly purchased from retail outlets in 5 different areas and analysed for iodine content, crystal size and label information.
All 38 packets were iodised but the iodine content in 68.6% of the packets were outside the range stipulated by the SLSI. In 52.8%, the mean iodine content was above the recommended upper limit of 40 ppm and in 15.8% below the recommended lower limit of 20 ppm. Only 31.6% of the packets were within the accepted 20 to 40 ppm range. None of the labels had all the required information.
Legislation enacted in 1993 stipulates that all edible salt sold for human consumption should be iodised. Our study shows that more stringent measures should be adopted to ensure that manufacturers and importers of iodised salt conform to the required specifications.
查明向公众销售的加碘食用盐是否加碘、碘化是否符合斯里兰卡标准协会（SLSI）的规范以及标签是否准确。
从5个不同地区的零售网点随机购买了11个不同品牌的38包加碘盐，并对其碘含量、晶体大小和标签信息进行分析。
所有38包盐均已加碘，但68.6%的盐包碘含量超出了SLSI规定的范围。52.8%的盐包平均碘含量高于推荐上限40 ppm，15.8%低于推荐下限20 ppm。只有31.6%的盐包碘含量在可接受的20至40 ppm范围内。没有一个标签包含所有所需信息。
1993年颁布的立法规定，所有供人类食用的食用盐都应加碘。我们的研究表明，应采取更严格的措施，以确保加碘盐的制造商和进口商符合要求的规范。
