I bought some swiss cheese slices probably 3 weeks ago and they have gone in and out of the freezer. Anyway, it says on the package that it should be eaten in 3 to 5 days, well that was long way gone. Ok so I just had two slices, they had absolutely no mold, but might have had a slight bitter taste or something i can't put my finger on. So did I give myself food poisining? am i going to be sick? i always thought if the cheese doesn't have mold on it its ok, i think when i was younger i would eat swiss cheese that had been open for a month or more and if it had mold i would just cut it off. HELP please!!
