Is it safe to eat a pork loin roast frozen for 2 years?

While a pork loin roast frozen for 2 years may still be safe to eat if it has been continuously frozen at 0°F (-18°C) or lower, its quality may have significantly deteriorated. Freezing preserves food from spoilage, but the taste and texture can be affected over time. It's advisable to check for any signs of freezer burn or off odors once thawed. If in doubt, it's safer to discard it.
