I just cold crashed a beer and forgot to remove the glass of sanitizer I had the blow off tube going into. As a result, the temperature change sucked it back into the carboy. Am I screwed here? It was diluted iodophor and it was no more than a cup. I'm curious (1) whether it is safe to drink (2) if it is, whether I should expect adverse flavours from such a small amount. Your input is appreciated.

Depending how long the iodophor was in your blowoff container will make a difference. I do know that iodophor when exposed to air seems to lose its color and become denatured. I used to use iodophor sometimes in my airlocks and I would see the color change happen rather quickly esp. when fermentation was active. So, if it was in an open container (at recommended strength) and sucked in at the end of fermentation, I would taste your beer. If you like it drink it up! I do not think that little of mixed iodophor would hurt you. If it was 1 cup of regular strength iodophor (not mixed with water), then I would say don't drink it!

i have no idea if it will kill you but I do know that you will never make the same mistake again if you dump it out.

I didn't dump it. The beer tastes bad to me, but I think it is unrelated to the iodophor getting into it. The solution was sitting there for a long time before it was sucked in, so I'm going to go with the hypothesis that it was denatured. Thanks for the suggestions.
