Refreezing already thawed bread I bought a loaf of bread some weeks ago, which the lady behind the counter explained was frozen (because it was leftover). This was okay for me. The bread was still frozen when I bought it and I let it defrost on the counter overnight.

Then we didn't eat all the bread (just about 50%) and I decided to put the leftover half back in the freezer (before it would spoil). 

Now I'm wondering: Is it ok to rethaw and eat the bread? I know there are several threads/questions regarding freezing - thawing - refreezing, but they don't handle bread (which I would believe to act differently than i.e. meat).

Thanks.
Yes, it is safe to freeze and rethaw bread, although it might not help with the quality.   Toasting it when you are finally ready to eat it will help bring out its best qualities.
