First I noted the too dark color It failed the taste test

As this is the very first time, I got a "bad" cheese, how are your experiences? Can this happens to the jalapeno cheese only?
To answer my own question: No, this can happens to Cheese / bacon too...
Sry, no other components. These cheese came out of my "Cheese" box. All my rations are stored in an AC room at constant temp. This cheese came also out of that cheese box: That was a same age plain cheese and it was OK.
