No. It may be that there is no problem with it, but you won't be able to tell. There are microbes that produce toxins. The heating might take care of the vegetative cells, but some toxins are not destroyed by heating. Unless where it was left overnight is as cold as a refrigerator, I would not risk using the beef stock.
it depends on the environment you leave it in. if it was warm because you had the heating on over night it's probably unsafe whereas if it was a cool temperature it will be fine because there was clean air getting to it.
No, it is not.
No.
Since the Alfredo contained chicken, it would not still be good if left out overnight. When in doubt, throw it out. It is not worth getting sick over.
Chicken is never okay outside of the fridge or freezer. If it's left out more than 20 or 30 minutes, I would throw it out.
no
No, you shouldn't eat chicken that was unrefrigerated overnight. It has had time for bacteria to grow and could make you very sick.
You better not LOL :P
Yes, unless the temperature in the room where it was left out was colder than 40 degrees Fahrenheit.
Yes
No. It is not safe.
No, your paintballing smoke grenade will not work if left outside overnight in the rain.
I would say no. It's a shame to waste good food, but this food in question has the potential to make people sick. ..
yes and no!! ;)
No. They should be discarded.
