Having a fridge that is practically overflowing can cause a lot of food waste. When food is packed into your fridge in a disorganized manner, it is easy forget about various items that may be shoved to the back or hidden under other products. When this occurs, foods can to go out of date without even being opened. To avoid this from happening, make an effort to declutter your fridge. A good way of avoiding food spoilage is to organize your fridge using the first in, first out method. So, as a general rule, put the newer food items to the back of the fridge and the older ones to the front.
