Uber fast-food chain McDonald's is launching a new campaign that will emphasize the quality of the food it serves to its hundreds of thousands of daily customers. The effort will kick off today with a two-day media event that is designed to dispell myths about McDonald's food, including that most of it is packed with additives and chemicals. Print ads will highlight how the eggs used in breakfast sandwiches are of the highest quality. The company also brought Reuters news agency into a processing plant to watch how burger patties are made and will add a section to their website that will allow visitors to track the lifecycle of various ingredients.
