Meat that is left in the freezer for a long period of time may show signs of freezer burn, but is actually still edible and should not be discarded solely because of the freezer burn.
Freezer burn may occur when frozen meat is not properly packaged. Signs of freezer burn include a dry and tough appearance, discoloration and "ice crystals" formation. Despite the quality changes, freezer burn does not affect food safety.
To prevent freezer burn, properly package meat before freezing, such as wrapping them in ziplock bags and removing any excess air to protect the meat's surface.
