It might be ok, but I'd be very carefull. Sometimes a quick rince in vinegar will kill bad smell. Sometimes it's all it is. But some times, like couple of days ago, my wife made chicken, and I srew the whole thing away it smell bad after it was madeand I did not even risk tasting it. Usually Iam very brave(stupid) when it comes to these things, I'd eat anything, just pick the green stuff off.
Just be carefull and smell and taste a very tiny little piece when it's done, and if you have even a sherad of doubt then toss it.
