I racked a batch of beer yesterday, and saved the yeast for my next batch. Today when I went to clean out the carboy, I gave it rinsed and poured it into the sink. In the rinse water were four dead flies. Not little fruit flies, but old ugly house flies.
The carboy cap and racking cane were left on the carboy after I emptied it, so I am pretty certain they were in there for the whole fermentation. 
I figure they must have gotten into the wort while it was chilling, since I don’t cover the kettle while the chiller is doing it’s thing. I usually let the wort get down to around 90 degrees and then start moving it around to get it down to temp. So chances are they flew in there when it was still pretty hot.
I really wanted to reuse this yeast because it is from East Coast Yeast, and not real easy to get a hold of. But now I am not so sure that would be a wise decision. I don’t want to dump the beer, but it kind of grosses me out.
Well what do you all think?

I wouldn’t reuse the yeast and I’d hope that the batch the flies were in was OK.
That’s what I was thinking.
I am bummed because I really wanted to reuse that yeast.
bummer about the yeast but I bet the batch turns out just fine.
This is exactly the reason I don’t “Fly” sparge ;D
Hope it turns out for you.
Fly PA? 
He’s really fly for a white [labs] guy.

It will probably taste great, and to reproduce you will be on the hunt for flies to add to the next batch
While I AM aware of the difference between New Zealand and Australia, reading your comment I was immediatly reminded of the Monty Python scetch about the mosquito hunters.
