IS it safe to leave cooked lamb at room temperature for an extended time?

No, it is not safe to leave cooked lamb at room temperature for an extended time. Bacteria can multiply rapidly when food is left out between 40°F (4°C) and 140°F (60°C), a range known as the "danger zone." To ensure food safety, cooked lamb should be refrigerated within two hours of cooking. If left out for more than two hours, it should be discarded to prevent foodborne illness.
