Is meat frozen for 2 years still good to eat?

Yes, 2-year-old frozen meat is generally safe to eat if kept continuously frozen at 0°F (-18°C) or below, as freezing stops bacteria from growing, but its quality (taste, texture), especially from freezer burn, will likely have decreased, making it best for stews, soups, or dishes where texture isn't critical. Proper wrapping (like vacuum sealing) helps maintain quality and prevent freezer burn, which is the main concern, not safety.
