 For example, certain trace ingredients that are "ingredients of ingredients" do not need to be listed.In Australia, some manufacturers who target the vegetarian market label their foods with the statement "suitable for vegetarians"; however, for foods intended for export to the UK, this labelling can be inconsistent because flavourings in ingredients lists do not need to specify if they come from animal origin.As such, "natural flavour" could be derived from either plant or animal sources.
