When a piece of uneaten meat is not taken out of a tank, what is the white stuff that forms around it?

It won't harm the fish directly, but it will have an effect on the water quality of the tank. That in turn will affect the fish.

He's right... always remove uneaten food within 5 minutes of feeding or you will get an ammonia spike due to decomposition.
