OAK BROOK, ILL. — McDonald’s USA has begun its roll-out of fresh beef that is cooked when ordered for all its Quarter Pounder and Signature Crafted Recipe burgers. The fresh beef is now available in approximately 3,500 restaurants and is set to be served in all participating restaurants in the contiguous United Stated by early May, the company said. McDonald’s first announced its plan to switch to fresh beef from frozen in March 2017.

“The switch to fresh beef quarter-pound burgers is the most significant change to our system and restaurant operations since All Day Breakfast,” said Chris Kempczinski, president of McDonald’s USA. “Over the past two years, we have been listening to our customers and evolving our business to build a better McDonald’s. We are proud to bring our customers a hotter and juicier quarter-pound burger at the speed and convenience they expect from us.”

All McDonald’s fresh beef quarter-pound burgers consist of 100% beef with no fillers, additives or preservatives, McDonald’s said. Quarter-pound burgers include the Quarter Pounder, Quarter Pounder with Cheese, Double Quarter Pounder and Signature Crafted Recipe burgers.

The fresh beef is now available in restaurants in Atlanta; Charlotte, N.C.; Memphis, Tenn.; Miami; Nashville, Tenn.; Orlando, Fla.; Raleigh, N.C.; and Salt Lake City. Over the next month, additional markets will include Denver, Houston, Los Angeles, San Francisco and Seattle, with full roll-out by early May.
