He probably drank a beer with it and will be ok.
He also, most likely, ate it all anyway. Mine would have told me he threw it out, thought I was over-reacting, and gone ahead and ate it....
College boys have nearly indestructible intestinal tracts.
I know you will worry until you talk to him tomorrow and know that he is ok....but try not to make yourself crazy. If you knew half the stuff he does, you would be certifiable by now.
