This should be fine as long as you follow the following :
1. Put high moisture food or those in a liquid state into sealed containers and make sure
they are tightly sealed. This will prevent any spillages from occurring.
2. Make sure you cool any hot food before placing it in the refrigerator. The hot food coming
in contact with the cold air can create water build-up.
If any spillages or water build up does occur then a warm cloth is recommended.
