The guy that wrote the article and mentioned refreezing did it to entice a picky eater, he thought the fact that it breaks down the cell walls and changed the smell might have been why his BP preferred the twice frozen mice.

I agree it does sound icky, and could harbor bacteria, but if it was promptly refrozen it probably isn't so bad bacteria wise.
