That's only partly true. Whilst cooking will kill bacteria it doesn't kill the toxins that might have been released while the food was tepid for a period of time. This is how the old rice sickness occurs.Proper cooking will kill most pathogens, so it's basically the same as cooking it the first time. Ie pretty safe. Put the leftovers promptly in the fridge or freezer once you take them off the heat.
