I have a bag of Better-Gro Premium Grade Orchid Sphagnum Moss and the only warning is on the reverse side of the bag where it states:
~ Caution: Wear gloves while working with any organic potting media.
edited to add: I've seen such warnings on other brands of Sphagnum I've purchased in the past too but don't remember exactly what it said.
