Put food like milk, meat, and cooked food in the fridge to keep cold.

You must be careful that you don't put too much warm food in the fridge at once. If you do this, it won't cool down fast enough, and the germs will grow inside the food.

Always put raw meat at the bottom of the fridge. If you put it further up, it may drip down on other food and contaminate it.

Food should be covered with plastic wrap before you put it in the fridge. This also stops it from being contaminated by any other food.
