Is this poison ivy?

Is this poison ivy or something else? It appears to meet the characteristics of poison ivy - 3 leaves, red stem, alternating leave groups on the stem. But... I question whether it's actually poison ivy because without paying attention, I've walked through it several times wearing sandals and shorts a few weeks ago with no rash or itching at all. I've only become concerned recently because two neighbors have now told them they encountered poison ivy in this same tree line behind our houses.

It looks like it to me. But the reaction to it is purely an "allergic" one, so if you're not in fact allergic to it at all, you'd never know you'd been "exposed" when you had been... And if you live somewhere where it's prevalent, and are over the age of about 6-7, and hadn't been kept indoors constantly by grossly overprotective parents, you'd probably know by now if you were allergic to it... ;)

I never was, and have still only ever reacted to it once, and that only in my mid-40s, and only after wrapping a long length of it around my forearm and pulling hard enough to lightly scrape my skin, in an attempt to uproot it. (An unsuccessful attempt, I might add. That stuff is a ah heck to get rid of!) And even then, I had only a very mild reaction that didn't last all that long, and that only after failing to do more than lightly rinse off my arm and hands. Why, you might ask, did I do something as ridiculous as all that? For the simple reason that, not being allergic to it, I'd never had to bother to learn to identify it all, so thought I was pulling on "just some random weedy vine"... It was only several hours later when I'd started itching a bit that I remembered having been told (by my horribly allergic brother) that there was a lot of poison ivy in the area and asked my niece if that's what that "annoying weed" I'd try to pull out was, in fact... :rolleyes:

Because even a single reaction to an allergen can lead to greater sensitivity to future exposure, I've been (a little) more careful since then, but before that, it would frequently turn out that I'd walked through big patches of it wearing shorts, without realizing it, and without even the vaguest hint of a reaction... As an aside, it's vaguely interesting (to me anyway), that my father and brother are both hideously allergic to it, while I don't remember my mother ever having that characteristic rash (though she didn't do all that much tramping through underbrush, either) so I guess that suggests the allergy is probably a recessive trait…

Poison ivy plants have a sticky oil on them that has similar properties to grease. It irritates some people, but I think there may be more to it than that. Perhaps, sometimes you don't get enough of the oil on your skin unless you really disturb it....or maybe you aren't allergic to it right now. Not everyone has a reaction to it, but eventually, you may as you age.

The most important thing to remember is to look out for it, avoid it, and if you do happen to get into it....use warm soap, water, and wash your hands thoroughly....paying attention to areas you don't typically reach.
This guy's video shows a good example using grease:

I'd go even a step further and suggest using dish detergent, which is a much better grease/fat cutter than ordinary soap. After I started itching (at which point it's too late to do much about it), I was kicking myself for not doing that, but like I said, I hadn't realized what I was yanking on in the first place. GIven the mildness of my reaction to even that degree of exposure, I suspect I'd have gotten away with no reaction at all if I had, abraded skin notwithstanding...

It's definitely poison ivy. Be careful. Sensitivities can increase with exposure. You could pull it bare handed and not get a rash, but end up full of blisters after doing it repeatedly.
