No Hogweed Locally

There have been no confirmed sightings of Giant Hogweed in the St. Clair Region Watershed so far this summer.

The non-native, invasive plant, has popped up along the Thames River Watershed though.

St Clair Region Conservation Authority Biologist Muriel Andreae says they’ve only confirmed the presence of “Cow Parsnip”, in Sarnia-Lambton, which looks similar.

Giant Hogweed is a serious health hazard for humans.

Its clear, watery sap contains toxins that can cause severe inflammation of the skin. There is also risk of severe burns if you get sap on your skin and the skin is then exposed to sunlight, as UV rays activate compounds in the sap.
