Can I still eat cooked ground beef if it hasn't been refrigerated in a while?

Toss it out!

Where I live..current temp are around 80 degrees F...ground beef would not do well sitting out for long. I would not even leave it out 1 hour

unless it is sticky or has a foul smell you can use it but I would cook it some more. but if it is sticky and or has a bad smell it is not good chuck it.

heat so that the meat and stuff that was cooked is really hot, and eat it in happiness! I usually make scrambled eggs on the remainder of the cooked ground beef from nachos or fajitas for breakfast the next morning without refrigerating it!

toss it or could make you very ill

If you cook it well you shouldbe ok but I would still throw it out just in case.

i wouldnt....meat can be left out for no more than 2 hours..after that bacteria starts to multiply and you would get very sick

Toss 'em.
