2. Dairy Products
- Storage: Store milk and cheese in original packaging or airtight containers on the middle shelves, where temperatures are stable.
3. Fruits and Vegetables
- Storage: Use the crisper drawers for fruits and vegetables. This section usually has higher humidity, which is better for these items.
4. Leftovers and Prepared Foods
- Storage: Store leftovers in clear, airtight containers to easily identify them and to limit food waste.
5. Condiments and Sauces
- Storage: Keep condiments on the door shelves as they are less sensitive to slight temperature changes.
Signs Your Refrigerator May Not Be at the Right Temperature
It can be challenging to identify if your refrigerator is not maintaining an optimal temperature. However, certain signs can provide insight:
1. Unpleasant Odors
A bad smell usually indicates spoiled food or that temperatures are too high, allowing bacteria to thrive.
2. Frost Buildup
Frost accumulation inside your refrigerator or freezer often indicates that the temperature is set too low.
3. Food Spoilage
If you notice that perishables spoil quickly or you find that your leftovers go bad sooner than expected, it might be time to check your temperature settings.
