Hello,

since I am a fan of beef jerky, I asked my girl friend to bring me some from the US on her recent trip here. She picked up some fresh made beef jerky from the butcher around the corner, i.e. not the packaged stuff.
Since to my understand jerky doesn't go bad, we put it in the kitchen cupboard, leaving it in its paper/plastic wrapper.
Now, after about 10 days, my girlfriend says it smells rotten. I am not home right now to check, but I am sure our tastebuds aren't that far apart from each other.

I am surprised Jerky actually can go bad. Is it something we did wrong when storing it, or is this part of the process (e.g. scrape off the bad stuff and enjoy the rest)?

Thanks,
Oliver
