Also, aren't there all sorts of toxic problems related to Poison Ivy's, uh, produce? Like with those kids she helped during No Man's Land?
Nah, that was with her skin. The kids had been okay until one of them touched her and got sick. I should think the produce itself was fine since part of her trade with Batman was providing it to the city in order to keep the park. Although I do admit the fruit there doesn't look too good. :\
