How we tested spoilage

We stored the unopened packaged Muenster cheese in our refrigerator at approximately 40°F (4°C) for a total of 30 days, closely monitoring its condition. After the first two weeks, we opened the package and noted the smell, appearance, and texture. The cheese retained its typical aroma with no signs of mold or discoloration, and its texture remained firm and smooth. We conducted a quick cook test by heating a small piece to 165°F (74°C) to check for any off-flavors, but it tasted normal. Ultimately, we discarded anything that appeared questionable, prioritizing safety above all.

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

To determine if unopened packaged Muenster cheese has gone bad, check for any visible mold growth or discoloration on the surface.
