Dangerous Giant Hogweed

Giant hogweed usually grows near waterways, experts have explained they are losing a battle to eradicate its presence, after homeowners have spotted the plant popping up in their parks and gardens.

The giant hogweed is dangerous when coming into contact with humans. The plant harbours toxic sap on its stems — and can be extremely dangerous when it comes into contact with bare skin.

"Any parts of the body that come into contact with the sap of a giant hogweed should be immediately washed with soap and cold water and seek medical advice. Further exposure to sunlight should be avoided for at least 48 hours."
