  • Consideration of Issues Related to Mandatory Nutrition Labelling
    E Agenda Item 4 b) CX/FL 10/38/6 JOINT FAO/WHO FOOD STANDARDS PROGRAMME CODEX COMMITTEE ON FOOD LABELLING Thirty-eighth Session Quebec City, Canada, 3 - 7 May 2010 CONSIDERATION OF ISSUES RELATED TO MANDATORY NUTRITION LABELLING (Prepared by Australia) BACKGROUND 1. At its 37th Session the Codex Committee on Food Labelling (2009), considered a discussion paper prepared by an electronic working group led by Australia, on issues and considerations related to mandatory nutrition labelling in the absence of nutrition claims. The discussion paper was also used to facilitate discussion at the Physical Working Group held immediately prior to the 37th Session of the Committee1. 2. The Committee then considered the report2 of the Physical Working Group that included discussion on the issues that should be considered when deciding on mandatory/voluntary nutrition labelling. The physical working group did not make any recommendations as to which type of labelling should be followed but rather had identified the issues that should be considered when deciding on mandatory/voluntary nutrition labelling: costs and benefits, application of mandatory nutrition labelling, implementation and support mechanisms, compliance and enforcement and international trade considerations. 3. During the discussion on the outcomes of the Physical Working Group several delegations expressed the view that the issue of mandatory nutrition labelling could be discussed together with the concept of having a core list of nutrients that are always to be labelled and a supplementary list of nutrients that could be labelled. Some delegations stated that flexibility should be left to member states on how to implement the various rules taking into account consumer understanding and the problems of small and medium size enterprises.
