To determine the iodine content of iodized salt at the production stage, to assess the perceptions and knowledge of salt producers about the prevention and control of iodine deficiency, and to examine the internal quality control procedures used during iodization in South Africa.
Salt samples were collected for iodine analysis by titration from the 12 producers iodizing salt in South Africa. Information on the producers' knowledge of iodine deficiency disorders and on internal quality control was obtained by means of questionnaires.
The legal requirement of 40-60 ppm iodine was met in 30.9% of salt samples; 57.9% contained more than 30 ppm iodine; 34.8% contained under 20 ppm iodine. There were shortcomings in perceptions and knowledge about iodine deficiency disorders and in the internal quality control procedures of a substantial proportion of the producers.
In order to encourage and support salt producers to achieve optimal iodization there should be an information, education and communication strategy aimed at improving knowledge of iodine deficiency disorders and at raising the standard of internal quality control procedures. External monitoring should continue.
测定南非加碘盐生产阶段的碘含量，评估盐生产者对碘缺乏病防治的认知和知识，并检查南非加碘过程中使用的内部质量控制程序。
从南非12家加碘盐生产商处采集盐样，通过滴定法进行碘分析。通过问卷调查获取生产商关于碘缺乏病知识及内部质量控制的信息。
30.9%的盐样符合碘含量40 - 60 ppm的法定要求；57.9%的盐样碘含量超过30 ppm；34.8%的盐样碘含量低于20 ppm。相当一部分生产商在碘缺乏病的认知和知识以及内部质量控制程序方面存在不足。
为鼓励和支持盐生产商实现最佳加碘效果，应制定信息、教育和宣传战略，以提高对碘缺乏病的认识并提升内部质量控制程序的标准。应继续进行外部监测。
