Terry, where did the ice come from? many restaurant ice machines are FITHY with mold because they figure "It's ICE! It can't be dirty!"
Ask if they've identified the organism yet and suggest they consider fungi.
Fungi are higher organisms than bacteria and are harder to kill, so if you need anti-fungals you won't enjoy it. :P
"By the pickled bones of Judge Rutherford, I command the illness to COME OUT of you!"
ps - if the ice did come from a restaurant ice machine and it can be shown to be the likely cause of your illness and sufferring, well... that's what lawyers are for.
