How long can mashed potatoes sit at room temperature?

Mashed potatoes should not sit at room temperature for more than 2 hours.

Here's why:

* Bacteria Growth: Bacteria can multiply rapidly at room temperature, especially in foods like mashed potatoes that contain moisture and nutrients.

* Food Safety: Leaving mashed potatoes out for extended periods can increase the risk of foodborne illness.

Here are some tips for handling mashed potatoes:

* Refrigerate promptly: Refrigerate mashed potatoes within 2 hours of making them.

* Store properly: Store mashed potatoes in an airtight container in the refrigerator.

* Reheat thoroughly: When reheating, make sure the potatoes reach an internal temperature of 165°F (74°C) to kill any bacteria that may have developed.

Note: If you're unsure about the safety of your mashed potatoes, it's always best to err on the side of caution and discard them.
