However, many people are unsure how long milk can sit out before it goes bad. In this article, we will discuss everything you need to know about how long milk can sit out.
Understanding the Shelf Life of Milk
The length of time that milk can be stored before it goes bad refers to the shelf life of milk. Milk is a perishable food item that can spoil if not stored properly. The shelf life of milk varies depending on several factors.
