The French consumer association UFC-Que Choisir has criticized major fast-food chains including McDonald's, Burger King, KFC, and Quick for a lack of transparency regarding the composition of their products. The group highlighted insufficient disclosure of ingredients, additives, allergens, and Nutri-Score information on menus and packaging. UFC-Que Choisir called for mandatory labeling of complete ingredient lists and Nutri-Score ratings to improve consumer awareness and safety. The association emphasized that dozens of ingredients are missing from current listings in France, raising concerns about consumer rights and food safety standards in the fast-food sector.
