Q: I always thought that after a food was reheated, it must be thrown out after service. Can TCS foods be prepared, cooled, reheated, and served repeatedly as long as they are held hot and cooled down properly?
A: Yes. FDA regulations do not prohibit reheating more than one time. It is sometimes industry that prevents this practice, more for quality reasons, (food dries out, taste or appearance may be compromised) but from a food safety point of view, it is safe as long as the cooling, reheating and storage is done properly according to FDA Food Code guidelines or regulations in your jurisdiction.
