Standard pasteurization does not heat the milk to a high enough temperature to completely kill all possible strains of bacteria and their spores that might be in it. To suppress the growth of these residual bacteria (if they are present) the milk must be refrigerated. However even refrigerated it should be completely consumed within 2 weeks of processing!
A different method called flash ultrapasteurization heats the milk to a much higher temperature than is used in standard pasteurization, but for a much shorter time to prevent damaging the milk itself does kill all possible bacterial spores that might be in it. Such milk can be stored unrefrigerated in sterile containers for up to 9 months.

What is the difference between pasteurized milk and sterilized milk?
Do not knowPasteurized milk is milk which has been heat-treated to kill pathogens which cause disease. Not all pathogens are removed during the pasteurization process, so pasteurized milk is not 100% sterile, but many people consider it to be safer to drink than raw milk which has not been pasteurized at all. The bulk of the milk sold in commercial grocery stores is pasteurized.Sterilized milk is Milk which heated to 120°C for a few minutes or to just over 100°C for 20 to 30 minutes and aseptically sealed in a narrow necked bottle with a crown cork. This process kills all pathogenic and most other microorganisms and spores and the milk will keep for 1 to 2 years. The milk is off white in colour and has a characteristic caramel, boiled milk taste which is not to everyone's liking.

Why might pasteurized milk eventually spoil?
The milk is pasteurized before being put into its container. Bacteria from the air can get inside when the container is being filled. They multiply slowly under refrigeration, and eventually the milk goes bad
