So 1 week ago I had a great brew day. Everything went great and we made a nice AG Irish Stout. After sitting in the primary for 1 week I then transferred to secondary to sit for 14-21 more days. As I was cleaning my carboy that I use for the primary, I was dumping all the sludge and yeast at the bottom and noticed something pretty good sized and black in the sludge... Yes it was a fly... That had been floating around in my primary for about 7 days fermenting with my delicious beer. I'm hoping some of you AG brewers who brew outside alot have had this happen before. I'm guessing it probably got in there during the boil as I was not standing there watching it the entire hour. The fermentation went great as was very active even 12 hours after brewing. OG was 1.052 and final was 1.010. I tasted the sample I took for measurement (before I noticed the fly) and it tasted great...not sure if the batch has been contaminated or if it's safe to serve to friends (without mentioning what was in the beer before they drank it) any advice or similar experiences would be appreciated.
Fly is sediment after 7 days

Call it Shoo Fly Irish Stout. Lots of protein! I fished one out of my boil on my last brew day.
If the fly got in during the boil, it was sterilized pretty quickly, and would be perfectly safe to serve. If the fly got in after chilling, you might wish to chill and carb that beer quickly once it's done fermenting.

Don't worry, they don't drink too much. 
caspider,
Not that it would be any consolation, but while stationed in Germany I visited a couple breweries in the Bavarian region. Both breweries had open top fermenters, quite huge in fact. Flies and who knows what else could have ended up in there, but there beer was always good. I should add that the fermenters were in very old buildings with steps that led to the top of the fermenters, which had a "deck" around them like you would see around a pool. That is where they would walk around to stir and skim.
I think your beer will be just fine.

Nothing could possibly go wrong - just don't look in the mirror after drinking a beer.
I saw a fly floating on top of my 2 day old krausen in a pale ale this summer.
I did not know if the fly got in during the boil or the chilling process, but just to be safe I kegged it up fairly quick and chilled it sooner than I had planned and it was a great beer.
