While it’s vital to keep your fridge cold enough to preserve food safely, too cold (below 32°F or 0°C) can freeze some items, particularly fruits and vegetables. Follow the recommended range for optimal results.
Myth 2: You Don’t Need a Thermometer
Many people rely solely on their refrigerator’s built-in settings without ever checking the actual temperature. This is not advisable, as inaccuracies in the display can occur. Always verify with an external thermometer.
Best Foods to Keep in Your Refrigerator
Knowing which foods to store in your refrigerator can help prolong their freshness and safety.
Perishable Items
- Dairy Products: Milk, cheese, and yogurt should always be stored in the fridge to prevent spoilage.
- Meat and Poultry: Raw meats should be stored at the back of the fridge where it’s usually the coldest.
Non-Perishable Items Best Resisted
Some items do not belong in your fridge, usually those that thrive at room temperature. Here are a couple:
- Bread: Bread can go stale in the fridge; it’s best stored in a cool, dry place.
- Tomatoes: Cold temperatures can alter their flavor and texture.
Conclusion
Maintaining the ideal temperature in your refrigerator is crucial for food safety, quality, and energy efficiency. By keeping your refrigerator between 35°F and 38°F, you can ensure food stays fresh while preventing the growth of harmful bacteria.
