Placing hot food in the refrigerator.

You should never put hot food into the refrigerator. This will cause the inside termperature to rise and spoil the foods already in there. The minimum temperature inside should be around 5 degrees, anything over and food will spoil. You are better off leaving hot food to go completely cold before putting into the fridge

It's harmful to your refrigerator.

Hello ARIANNELEXI....... Putting hot food in a refridgerator will not cause the food already in there to spoil. It will make the Refridgerator work harder to cool your foods, costing you more . Food should be allowed to cool before placing it in a refridgerator. Tom

Actually yes and no. If you put in hot food, then that raises the temperature inside the fridge, at least for some time till the cold air influx cools the substance. Now if there are other items in the fridge that need to be kept cool at all times, they then are at the risk of getting spoiled. The item that you have kept might itself not be spoil, but other items are in risk. Apart from this it is also not advisable on the grounds that it leads to excessive power consumption by the refridgerator. Cheers! Ram
