How long can soup with milk be left out?

Here's why:

* Bacteria growth: Milk is a great breeding ground for bacteria, especially at room temperature. This can lead to food poisoning.

* Spoilage: The milk in the soup can sour and become unpleasant to taste.

To be safe, it's best to:

* Refrigerate soup with milk within two hours of making it.

* If left out longer than two hours, discard it.

Important Note:

* This rule applies to any soup that contains milk, even if it's a small amount.

* If you're unsure about the safety of your soup, it's always better to err on the side of caution and throw it out.
