Plant question - poison sumac?

[d-dave]

So when we recently bought a new home, and our realtor, whose husband works in lawn care, commented that we had some poison sumac. My mother in law said it was poison sumac.  I figured I'd address it once we got back from vacation and moving.

So what I know about poison  sumac is that it likes super wet soil, like a bog. Nope, don't live in a box. Evenly spaced, round leaves on red stems.  OK, looks promising, except my plants all have serrated leaves.

So I don't think I have poison sumac, I already started killing some poison ivy and oak, but I'm not sure what this is.  Any ideas?

I'm highly allergic to all three, I dint have touch it. On real warm days, if just walk near the poo I break out.

It almost looks like stinging nettle. Hard to tell because the picture blurs when I zoomed in, but that poo is nasty. Instant rash and your skin burns and itches like crazy.

Really?  I haven't touchedit yet! I have a poo ton of these plants growing everywhere.  

I'll get some better pics tomorrow.  I thought it might be a more benign plant.
