If you’re looking at a frozen piece of meat, it could look like frost crystals in the vacuum-sealed bag or on the meat’s surface. As it thaws, you might notice a leathery or waxy texture on the exterior of the meat, which indicates moisture loss; on defrosted red game meat like venison or elk, freezer burn will present as a brick-brown or gray color. Trim these pieces off to reveal the unaffected meat underneath.
