Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Promptly refrigerate opened cheese to prevent bacterial growth and spoilage. Discard any cheese left in the danger zone for too long.
Safe Handling
Always wash hands before and after handling cheese.
Avoid cross-contamination by using clean utensils and cutting boards.
Do not leave cheese at room temperature for more than 2 hours (1 hour if above 90°F/32°C).
