Bagged milk is overdue for 3 days and can't be drunk any more. Bagged milk can guarantee the quality and taste of milk within the shelf life. If the shelf life is over, the milk may be contaminated by bacteria, and the bag may be swollen with the naked eye, or it may smell peculiar smell or odor. There is also a part of expired milk that is slightly contaminated by bacteria, which can't be identified by naked eyes, but it is very likely that symptoms of gastrointestinal discomfort will occur after drinking, such as nausea, vomiting, abdominal pain, diarrhea and other symptoms. Therefore, bagged milk can no longer be drunk no matter how many days it expires.

In fact, expired milk can be used for many purposes, but it can't be eaten any more. After all, expired milk indicates that mildew has already occurred in it, which will grow a lot of germs. In addition, it should be stored in a shady area when the milk is stored in bags. If the temperature is too hot, it will accelerate the mildew of milk.
