Skin contact with its sap in the presence of sunlight can result in severe burning and blistering (Nielsen et al. 2005). For this reason, giant hogweed is both a Virginia and Federal noxious weed (USDA APHIS, VDACS). If you are exposed to the sap, immediately get out of the sun, wash with soap and water, and if a reaction begins to occur, seek immediate medical attention (Hyypio and Cope).5 pagesapplication/pdfen-USVirginia Cooperative Extension materials are available for public use, re-print, or citation without further permission, provided the use includes credit to the author and to Virginia Cooperative Extension, Virginia Tech, and Virginia State University.giant hogweedExtension publicationhttps://www.pubs.ext.vt.edu/content/dam/pubs_ext_vt_edu/spes/spes-48/SPES-245.pdfHeracleum mantegazzianumIdentificationControl
