Freezer burn is a common issue that many users face. This issue is related to how the food is packaged that you keep in the refrigerator. Freezer burn happens when the food dehydrates by being exposed to the freezer air. Hence, when you want to keep food in the refrigerator for several days you should put it in an airtight container or plastic bags that are made for preserving foods. Still, there is no harm to consume food with freezer burn as the taste only gets changed.
