Here’s the deal: the optimal temperature for a home freezer is zero degrees Fahrenheit, or minus eighteen degrees Celsius. Stick a thermometer in there and check—your freezer dial might be lying to you. I’m serious; most built-in thermostats are about as accurate as a weather app in a hurricane.
At 0°F, bacterial growth essentially hits the pause button. That’s why food doesn’t “go bad” in the freezer—it just gets sad and freezer-burned over time. Freezer burn isn’t a safety issue, by the way; it’s a texture and taste issue. So don’t throw out that steak just because it’s got a few white spots—it’s not spoiled, just embarrassed.
If your freezer runs at 10°F or higher, you’re basically giving bacteria a cozy winter cabin. They won’t party, but they’ll survive. And nobody wants a houseguest like that in their frozen pizza.
