How Long Does a Frozen Turkey Remain Safe to Eat?
Question: I bought a frozen turkey about a year ago but never got around to cooking it. It's been in the freezer the whole time - is it still safe to eat and if so, will it taste okay?
Answer: Yes — you should be fine on both fronts.
As the U.S. Department of Agriculture points out, foods that are kept constantly frozen at 0°F or lower will keep safe indefinitely.
When it comes to quality, the story is different: Over time, all frozen foods will eventually start to go downhill when it comes to texture, flavor and taste. In the case of your whole frozen turkey, you’ll experience the best quality if you eat it within one year, as detailed here.
