Can be poisonous to eat but not touch? I try to do a good job of wearing gloves, pants, ect but some of the leaves fell across my shoulder/arm when cutting it down. Then I walked through where it was laying on the grass after putting it in the yard waste bucket. Was worried about oil on the bottom of my shoes tracking inside and I think I did wipe my face with my shirt sleeve once without thinking.
Had some bad times with poison ivy in the past and now I tend to be a little cautious, overly I'm sure, around suspect plants.
