When should fridge and freezer temperatures be taken?

Fridge and freezer temperatures should be taken regularly, ideally once a week, to ensure food safety and proper storage conditions. It's best to check temperatures after the door has been closed for several hours to allow the appliance to stabilize. Additionally, if you notice any changes in food texture or spoilage, or after a power outage, it's crucial to verify the temperatures immediately. The recommended fridge temperature is below 40°F (4°C) and the freezer should be at 0°F (-18°C) or lower.
