Longevity of String Cheese at Room Temperature

String cheese, a form of mozzarella, is a popular, quick snack for cheese lovers worldwide.

You might wonder how long it can sit out at room temperature before eating is unsafe.

String cheese can safely sit at room temperature for approximately two to four hours.

Controlling the temperature is key when dealing with any dairy product, string cheese included.

Cheese, especially string cheese, can spoil if left at room temperature for too long.
