PrepTest 60, Section 3, Question 17
Any food that is not sterilized and sealed can contain disease-causing bacteria. Once sterilized and properly sealed, however, it contains no bacteria. There are many different acceptable food-preservation techniques; each involves either sterilizing and sealing food or else at least slowing the growth of disease-causing bacteria. Some of the techniques may also destroy natural food enzymes that cause food to spoil or discolor quickly.
