Thanks for posting. I have heard of this, but like Sewbizgirl says, you have to be aware you've come in contact with it. I'm very sensitive to it and can get it from secondary contact like with my dogs. My neighbor's son told us that he had found some in the corner of his mom's yard when he was over cleaning up for her. It was coming from our side of the fence. I made my husband go out to the corner of the yard where we have the "jungle" and clean it out. I wouldn't go near that corner for weeks.
