How we tested spoilage

We stored the unopened blue cheese crumbles in our fridge at a consistent temperature of around 40°F (4°C) for 14 days, closely monitoring the expiration date. After opening the package, we held the cheese for an additional week, during which we observed its smell, appearance, and texture daily. On day 21, we noted a faint off odor and some unusual mold growth beyond the typical blue veining. We also checked for any changes in texture but found it remained crumbly. To verify safety, we briefly heated a small portion to 165°F (74°C), but given our observations, we discarded the entire batch to prioritize food safety.
