Is pizza OK to eat after five hours sitting in a car?

It’s generally not safe to eat Pizza that has been sitting in a car for five hours, especially if the temperature inside the car is warm. Bacteria can multiply quickly in food left at room temperature, which can lead to foodborne illnesses. If the pizza was kept in a cooler or the car was air-conditioned, it might be safer, but it's best to err on the side of caution. Always prioritize food safety to avoid health risks.
