FYI
Giant hogweed (Heracleum mantegazzianum) is a Federally listed noxious weed. Its sap, in combination with moisture and sunlight, can cause severe skin and eye irritation, painful blistering, permanent scarring and blindness. Contact between the skin and the sap of this plant occurs either through brushing against the bristles on the stem or breaking the stem or leaves.

    I am putting together some safety advice for grounds workers. Would it be ok to use the photo of the arm blisters to help get the point over regarding the seriousness of this plant?

    In Michigan, the Hazmat Unit is called in to destroy this plant. DO NOT come near it.
