Regulation No. 139 on voluntary labelling of foods with the Keyhole.

The present Regulation applies to the voluntary labelling and presentation of foods with the Keyhole symbol, which is linked to the food’s content of fat, sugars, dietary fibre or salt. It regulates, among other things, the Keyhole's design, the products that can be labelled with the Keyhole, the products that can not be labelled with the Keyhole, general conditions for using the Keyhole, and supervision and penalties. Appendix 1 contains the Keyhole's graphic design. Appendix 2 contains a list of groups of food products that can be labelled with the Keyhole and the conditions that apply to each group.
