Are there any members of your family, that somehow don't get poison ivy? I only ask because my sibs and I don't get it, no matter what we do. Therefore its my responsibility to make the initial cleanup of the garden, every year before the rest of the family goes in there. I pull it out by the root and make huge piles of the stuff and set it all on fire, after everyone is safely inside. If DS would attempt to do that, it might mean a doctor visit.
Also, when I'm done, I"m off limits to everyone until I've been decontaminated. My clothes goes straight in the wash...alone with lots of soap and my bath stuff. No one goes outside at all to avoid the smoke.
I would think that you can probably come into contact with a small amt and quickly deal with your produce, provided you decontaminate yourself and clothes real quick, as I do, but in your case, you would be dangerous to your own self, where I'm only dangerous to everyone else......I guess if you hurry up and deal with yourself....less damage. I hope its not too bad. I guess you just best use aloe or oatmeal soaps and maybe a little (very little) bleach in your bath. Note: some would disagree with my last statement, but it does have a drying action, provided you don't burn your skin with it.
