Frequently Asked Questions

What's the difference between expiration and best quality dates?

Fontina cheese degrades over time due to factors like moisture loss and mold growth. While the expiration date indicates safety, the best quality of Fontina cheese is usually before the expiration date. As the cheese ages, it may become drier, develop off-flavors, or mold. It is recommended to consume Fontina cheese within a reasonable period after opening to enjoy its optimal taste and texture.

How can I tell if Fontina Cheese Sold in Wrapped Block Opened has gone bad?

To determine if opened Fontina cheese has gone bad, look for any mold growth, a strong unpleasant smell, or a slimy texture. If you notice any of these signs, it is best to discard the cheese to avoid potential foodborne illnesses.

What are the food safety risks?

Fontina cheese, like other dairy products, can pose risks of foodborne illnesses if not handled properly. Common pathogens associated with cheese include Listeria monocytogenes and Salmonella. To prevent contamination, it is crucial to store Fontina cheese at the correct temperature, avoid cross-contamination with raw foods, and consume it before the expiration date. High-risk scenarios include leaving the cheese at room temperature for an extended period or consuming unpasteurized varieties.

What are some pro storage tips?

To maintain Fontina cheese's quality, store it in the refrigerator at around 35-40°F (1.6-4.4°C) wrapped in parchment paper or wax paper to allow it to breathe. Avoid storing it in plastic wrap as it can trap moisture and promote mold growth. Before consuming, it is recommended to let the cheese come to room temperature for optimal flavor. If mold develops on the surface, you can cut it off before consuming the remaining cheese.
