How long can a cured cooked ham be unrefrigerated?

A cured cooked ham can typically be left unrefrigerated for up to 2 hours, as long as the ambient temperature is below 90°F (32°C). If the temperature exceeds this, it should not be left out for more than 1 hour. After these time limits, the risk of bacterial growth increases significantly, making it unsafe to consume. For longer storage, it's best to refrigerate or freeze the ham.
