Toxic danger

The sap of giant hogweed contains toxic chemicals called furanocoumarins. These are produced as an insect defence and, along with the loss of native foodplants, this may contribute to a reduction in invertebrate biodiversity. The same chemicals also have antifungal properties and are found in the roots as well as the leaves. It is therefore thought that giant hogweed can suppress soil fungi, which are crucial for maintaining soil fertility

Advice from the Centre for Ecology and Hydrology outlines reports of long-term damage to ducklings that had trodden on giant hogweed tissue. Even three weeks after their brief exposure, the beaks were deformed and the feet darkly discoloured. This highlights the risks posed to wildlife as well as humans.
