Food left on counter all day - garbage or just cook it really hot?

[strangemelodies]

I left the house at 9:30am, it's now after midnight and came home to find a large dish of leftover rice & beans left on the counter. I dished some up into tupperware for lunch before leaving and I guess forgot to put it back in the fridge. I made it the day before, and it was cold when it started its day on the counter. For food safety, is this garbage, or is it fine if I just cook it really hot? It's a lot of food to put in the trash.

I live in NJ and the house was probably around 67 degrees all day.

Thanks!
