Room Temperature Safety
The 'Danger Zone' for food is between 40°F (4°C) and 140°F (60°C), where bacteria can multiply rapidly.
Always return blue cheese dressing to the refrigerator immediately after serving or use to prevent bacterial growth and maintain safety.
Safe Handling
Always refrigerate blue cheese dressing promptly after use.
Do not leave blue cheese dressing at room temperature for more than 2 hours (or 1 hour if the temperature is above 90°F/32°C).
Discard any dressing that has been left in the danger zone (40°F-140°F) for too long.
