Fluoridated water must be treated as a medicine, and cannot be used to prepare foods. That is the decision of the European Court of Justice, in a landmark case dealing with the classification and regulation of ‘functional drinks’ in member states of the European Community. (HLH Warenvertriebs and Orthica (Joined Cases C-211/03, C-299/03, C-316/03 and C-318/03) 9 June 2005)
What are the implications of this? Tap water cannot be used in prepared foods of any kind, foods made with tap water cannot be imported either between European states or from the US. Unless they do full medical testing on it as for any other drug or functional food.
I do note that the European countries seem to be ignoring the Court of Justice decision which was given a few years ago and only the anti-flouridation forces are making much of it.
