Signs of Spoilage

- Off-odor or sour smell
- Slimy or unusually hard texture
- Discoloration
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Promptly refrigerate Swiss cheese after purchase and after serving to minimize time spent in the danger zone.
Safe Handling
Always wash hands with soap and water before and after handling cheese.
Avoid cross-contamination by using clean utensils and cutting boards for cheese.
Do not consume cheese that has been left at room temperature for too long.
