need help with whey gone bad

[Guest guest]

I made whey awhile ago from pasteurized yogurt from the store - the

biodynamic kind. I used it last night and it smelled like blue

cheese and had a reddish thing on the rim of the bottle and some

small black specs on the inside of the bottle cap.

When I poured some out, it was clumping into a cloudy liquidy mass.

I poured it into beans to soak - haven't made them - too scared to.

I also poured the whey (not knowing it might be off) into three

bottles of homemade gingerale I made.

Does anyone have experience with knowing when whey can turn harmful?

Help!

Thanks,
