No. From what I know, ants don't carry diseases. But then, on the other side you can think about the surfaces that ant walked on: poop, dead animals etc. Anyways, it's not dangerous at all.
Hey, is it safe to eat my pizza that are invaded my a few ants (maybe about 15)?
I washed it and reheat it in my microwave.
As far as I know, it is safe. Ive already eaten by accident ants, caterpillars and a spider and Im not dead and didnt have any problems after, except the horrible taste, yet again, you arent eating them, but eating something that was stepped on by ants.
