How long can cheddar cheese stay out of the fridge when not cut?

Uncut cheddar cheese can safely stay out of the fridge for about 6 to 8 hours at room temperature, depending on the ambient conditions. If the temperature is particularly warm, it's best to limit this time to ensure safety and quality. After this period, it's advisable to refrigerate it to prevent spoilage. Always check for any signs of spoilage before consuming.
