Feeding the Food Spoilers Feeding the Food Spoilers Most foods cannot be kept very long before they start to change in some way. Often, these changes are unpleasant. Many foods get smelly and mushy or slimy.
Some foods get very hard and tough.
Sometimes, these foods can make you sick. We call some of these food changes spoilage. Spoiled food is something that we don't want. But not all changes in food left standing are unpleasant. Sometimes the changed food is safe to eat.
