Room mate left pasta with tomato sauce out on the stove and it sat there for 2 days
Chris, this is your Mom speaking.
TOSS IT! Food poisoning is not the fun experience you might think.
BTW, is your new roommate going to be more conscientious?
how about a one day old burrito?
No to both! Anything left out overnight (or more than a couple of hours) THROW IT OUT! I had food poisoning and it was the worst thing ever! Was severely sick for a month and would not wish it on anyone. One of the first things taught to us in Food Class, "When in doubt, throw it out!" So true!
If you have to ask...
Why would you even want to eat it even if you could? It's like $2 worth of food.
