A useful trick for reducing the chance of food poisoning with take out is to re-heat the food in a microwave.
You do have to get the internal temp of the food pretty high to do a good job, like 165+, but for many foods it works great.
Won't eliminate the risk from all pathogens but it's not a bad precautionary measure.
I like the idea of Dinesafe. There's not nearly enough effort on enforcing health codes.
