Personally I've never ate left over food, I don't like the idea of it but hubby will do it and I have to FORCE him to refrigerate but he doesn't always do it and has never had food poisoning.
I think by it being at least refrigerated for a period of time the risks will be minimised although there are still going to be some - even cooking fresh food and eating straight away carries some degree of risk.
The main thing I would be concerned about though is the meat, not the pasta.
If you have any symptoms, go straight to the hospital and tell them you suspect you have food poisoning. Better to 'over-react' than brush concerns aside.
"Risks of Reheating Food
Reheating food that has been properly stored in the fridge will not pose the same health risks as food that has been left out all night long. Remember that a single bacterium will multiply rapidly under the right conditions, which poses the serious risk of food poisoning.
Even if you reheat food that has been left out overnight, some bacteria such as staphylococcus aureus (staph), can actually form a heat-resistant toxin that cooking alone will not destroy. That means the risk of food poisoning will not be eliminated by reheating the food."
