The freezer can be a lifesaver — the perfect place for leftovers you can’t finish any time soon, in-a-pinch meals for the family, and sweet treats for hot summer days. And according to the USDA, food kept consistently at 0°F will always be safe — it’s just the quality of the food that will suffer (read: It will be OK to eat, but it might not necessarily have the taste or texture you like).
That being said, not everyone’s freezer is 100 percent consistent, and the temperature can fluctuate if you’re opening the door a lot, or if you live in an area that frequently loses power. Here are some signs that something might have gone bad. (Note: None of them involve tasting something to find out!)
