How long will pea soup stay good out of the refrigerate made a fresh batch and left it overnight?

It's generally not recommended to leave pea soup out of the refrigerator overnight. Here's why:

* Bacteria Growth: Bacteria can multiply rapidly at room temperature, especially in foods like pea soup that are high in moisture and protein. This can lead to foodborne illness.

* Spoilage: The soup can start to develop an off smell, taste, or texture as it sits out.

Safest Practice:

* Refrigerate promptly: After cooking, cool the pea soup quickly and store it in the refrigerator within 2 hours.

* Use within: Store properly refrigerated pea soup for up to 3-4 days.

Exception:

* If you are certain the soup has cooled down to room temperature within 2 hours of cooking, and you plan to eat it within 4 hours, it might be safe to leave it out for a short time. However, this is not a recommended practice as it increases the risk of bacteria growth.

Always err on the side of caution. If you're unsure about the safety of any food, it's best to throw it away.
