Can you eat pasta that has been left out overnight?

It is not recommended to eat pasta that has been left out at room temperature for more than two hours. This is because bacteria can grow rapidly on cooked pasta that is left out at room temperature. If pasta is left out for more than two hours, it should be discarded.

However, if the pasta was refrigerated promptly and stored properly in an airtight container, it can be safe to eat for up to four days. Before eating, be sure to reheat the pasta to at least 165°F (74°C) to kill any potential bacteria that may have grown.

It's important to note that some people are more susceptible to foodborne illness than others, such as pregnant women, young children, the elderly, and people with weakened immune systems. These individuals should be especially careful when it comes to food safety and should avoid eating pasta that has been left out for an extended period of time.
