As long as your freezer is working at its optimal level, keeping food consistently at 0°F, the food inside will be safe to eat indefinitely. There’s no safety concern with anything that’s been properly frozen. The real issue is just how much you’ll actually enjoy it, as some foods might not have the taste or texture you prefer when eating something a year later.
Not willing to risk eating leathery meat? We don’t blame you. Luckily, there are plenty of official guidelines that can help you figure out if something’s been in the freezer for too long. Just make sure you label your groceries before you stash ’em away, so you can count up the months.
