temperature of refrigerator and freezer
1 A fridge should have a temperature of between 37Â°F(3Â°C) and 40Â°F (5Â°C). Any higher and the food will go off, any lower and youâll lose nutrients and fresh food can be ruined.  The ideal freezer temperature is 0Â°F (-18Â°C) which will store food safely and stop bacteria forming.
