(HealthDayNews) -- Are you worried about those grayish-brown, leathery looking marks on the food in your freezer? No need to fret. According to the U.S Food and Drug Administration, freezer burn is a food-quality issue, not a food-safety problem.
The dry spots are caused by air seeping through packaging that's not airtight, and the color changes are a result of chemical changes in the food's pigment. The food is fine to eat -- just cut away the dry areas either before or after cooking the food.
Next time you freeze food in plastic bags, push all the air out first.
