There are no specific provisions in place, but they appear to accept the term “prebiotic” as part of the mutual recognition principle, which refers to the principle of EU law under which goods that are legally sold in one EU Member State can be marketed and sold in another. For the exported, this means that a product legally on sale in one country should not have to meet a second set of requirements in the country to which they are exporting.
