How long can pies sit at room temperature and still be fit to eat?

It's not recommended to leave pies at room temperature for extended periods, especially in warm weather. Here's why:

* Bacteria growth: Bacteria thrive at room temperature and can quickly multiply in food, leading to spoilage and potential foodborne illness.

* Spoilage: Pies can become dry, stale, and lose their flavor and texture.

* Safety: The "danger zone" for bacterial growth is between 40°F and 140°F (4°C and 60°C). Pies left out in this temperature range for more than two hours are considered unsafe to eat.

How long is "too long"?

* For pies with custard or cream fillings: It's best to refrigerate them immediately after cooling.

* For fruit pies: They can sit at room temperature for up to 2 hours if the filling is well-cooked and the room temperature is below 90°F (32°C).

Best practices:

* Refrigerate pies as soon as they cool.

* If a pie has been out at room temperature for more than 2 hours, discard it.

* Always check for signs of spoilage, such as mold, off-odor, or a change in texture.

It's better to err on the side of caution and refrigerate your pies promptly. If you're unsure, it's always best to err on the side of safety and discard the pie.
