Michigan – This Plant is More Dangerous Than Poison Ivy, Oak, and Sumac
Did you know there is a plant that grows in Michigan that is so dangerous that it can cause third-degree burns?
This invasive plant is considered a public health hazard that ranks higher than poison ivy, poison oak, and poison sumac with respect to its potential to harm humans.
You've more than likely seen this plant growing alongside the road but never thought twice about it.

What Plant is More Dangerous Than Poison Ivy, Oak, and Sumac?
Relative to the carrot, the Giant Hogweed can grow 10 to 15 feet tall and can be extremely dangerous if handled. This is one plant you don't want to mess with. If not careful you could end up with third-degree burns.
According to michigan.gov, exposure to Giant Hogweed can result in a severe skin reaction called photo-dermatitis or photo-sensitivity, which can occur up to 48 hours after contact. The sap is so toxic that it can cause your skin to blister when exposed to sunlight. This stuff is so nasty that if your eyes come into contact with the sap, it may result in temporary or potentially permanent blindness.
Back in 2019, the teen in the photo below came into contact with Giant Hogweed and has hospitalized with severe burns.

What to Do if You See Giant Hogweed:
If you see a plant that appears to be Giant Hogweed and you need help identifying it, send an email to MDA-Info@Michigan.gov, along with any pictures.
E-mail four photos: 1. Whole plant, 2. Leaf, 3. Flower/seed head, 4. Where a leaf joins the stem.
Apparently, only 2% of suspect plants submitted to MDARD for identification are confirmed as Giant Hogweed.
