I had an NC RyJ tubos given to me for a birthday or sonething thankfully I opened it because it had mold when I got it. It was just a few spots on the wrapper like that one that wiped right off. I tossed the tube and quarantined the stock in a zip lock for a few days and nothing came back. I eventually smoked it and haven't died yet, you should be fine as long as it isn't on the foot.
