OK.. this one I will have to sit back and let the experts comment on.
Just a few questions though:
How long has it been in secondary..? When did the film show up ? Have you taste tested it from under the film..?
I personally would taste test it and bottle it but leave a bit more in the carboy.. as to not get that in it.. Because since its in secondary, its already beer. Just a matter of it tastes bad or not.
Also as someone has also pointed out.. you can not get sick from anything in Beer..
(And someone says I don't listen.. its the SWMBO.. but I digress)
