RESUMEN
Sodium and potassium fluoride are used for the fluoridation of household salt. Addition of fluoride is carried out either by the wet or the dry process. Qualitatively good fluoridated salt can be produced by using either method. In the wet process, a solution of potassium fluoride is mixed homogeneously with the salt. For the dry mixture, only sodium fluoride with a small granule size is suitable. Apart from the mixing methods used by the larger salt manufacturers, there are low-cost solutions for very small producers.

In seven European countries there are national legal regulations, or salt producers have obtained individual authorisations, for the production and marketing of fluoridated edible salt. On the basis of EU mutual recognition rules, there are other countries which import fluoridated edible salt. All European countries practise salt fluoridation on a voluntary basis. In the near future, a European regulation is expected to supersede the national conditions.
