Is it safe to eat chicken that has been frozen for 3 years?

No, it is not safe to eat chicken that has been frozen for 3 years. The USDA recommends that raw chicken should be cooked within 1 year of being frozen, and cooked chicken should be consumed within 3-4 months. Freezing chicken for longer than these periods can lead to deterioration in quality and potential safety risks, such as freezer burn and spoilage. Additionally, the flavor of the chicken may be adversely affected by prolonged storage.
