McDonald's might swap all its frozen beef patties for fresh ones

Where's the fresh beef? Apparently, it'll soon be under the golden arches.

McDonald's is swapping out frozen burger patties for fresh beef in 14 of its Dallas-area locations.

The company has been touting 100 percent real beef patties for some time now, but its website says freezing them maintains "the freshest flavor."

McDonald's has been fighting slumping sales in the U.S., and testing fresh beef could be another effort to lure in customers.

Last October, the company started serving all-day breakfast at U.S. locations. And at the end of last month, McDonald's started testing chicken nuggets without artificial preservatives.

And some of McDonald's biggest competitors, like Shake Shack, use fresh beef burgers as a main marketing point.

While it's still early to see if fresh beef will be rolled out everywhere, a company spokesman told USA Today, like any test at the company, this is simply meant "to see what works and what doesn't."
