Found recently near Michigan State University, a patch of Giant Hog Weed growing near Lansing, required eradication by a team of Michigan State personnel suited up in hazmat gear. The weed, which can grow more than 5 feet, causes extreme blistering of the skin which will take months to clear up and , more importantly, causes blindness. The hairy surface of the huge leaves carry a toxin which is dangerous to animals and people. The patch of Hog Weed,shown in this video, appears inocuous. However, it was growing in a backyard where children regularly play, and the homeowner was unaware of the toxic nature of the plants. Apparently the weed is spreading across the State of Michigan.
