In addition to being fresh instead of frozen, McDonald's points out that the new burger patties -- like the company's current burger patties -- are 100% beef and are free of preservatives, fillers, or other additives. The hamburger purveyor said the shift is a response to its customers' "changing expectations," when it comes to ingredients in food and how it's served. Over the last few years, the company has started to clean up its menu by switching to antibiotic-free chicken, removing artificial preservatives from McNuggets and other menu items, getting rid of high fructose corn syrup in its buns, and committing to sourcing only cage-free eggs by 2025.
"Serving All-Day Breakfast, moving to cage-free eggs and testing delivery are all proof of our commitment to building a better McDonald's," CEO Steve Easterbrook said in a statement. "And we are committed to transforming more aspects of our business, including offering a more modern and enjoyable dining experience, adding new levels of convenience and technology, and making more positive changes to the food we serve."
