How we tested spoilage

We tested the spoilage of our opened Asiago cheese by storing it in the fridge at approximately 40°F (4°C) for 14 days. We observed the cheese daily, noting any changes in smell, appearance, and texture. Initially, it had a pleasant, nutty aroma, but after a week, we detected a faint off odor. By day 14, we noticed some slimy texture and dried edges, along with the presence of unusual mold growth, which was concerning. To verify its safety, we briefly heated a small piece to 165°F (74°C), but given the signs of spoilage, we ultimately discarded the cheese to prioritize safety.

Frequently Asked Questions

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

The expiration date on Asiago cheese indicates the date by which the cheese should be consumed to ensure maximum safety and quality. Beyond this date, there is an increased risk of bacterial contamination and deterioration in quality.

Consuming Asiago cheese before the expiration date ensures both safety and optimal taste experience.

What are the food safety risks?

Asiago cheese is a type of hard, aged cheese made from cow's milk. Like all dairy products, Asiago cheese is prone to bacterial contamination if not stored properly.
