                                According to McDonald's official allergen information, the U.S. McChicken patty does not contain milk ingredients, but cross-contamination is always a risk. So, do McDonald's McChickens have dairy? While the main components are surprisingly dairy-free by ingredient, factors like regional recipes, preparation, and shared equipment can introduce traces of milk.
