How do bacteria spoil food?

Bacteria can cause food spoilage by breaking down the food, producing acids or other waste products during this process. Signs of food spoilage may include an appearance different from the food in its fresh form, such as a change in color, a change in texture, an unpleasant odor, or an undesirable taste.

How can we reduce food spoilage?

An easy way to keep track of your food is to place a label on the container stating the date you opened it. Don’t store food on top of the fridge—it’s too warm. Keep meat on the bottom shelf where the temperature is coldest. Keep milk as low as it will fit, not in the doors: It’s not cold enough there.
