Important Information on Giant Hogweed
Giant Hogweed has been added to Schedule 9 by The Wildlife and Countryside Act 1981 (Variation of Schedule 9) (England and Wales) Order 2010: this means that it is illegal to plant or otherwise cause to grow Giant Hogweed in the wild.
Giant hogweed is highly invasive but more concerning are its ability to inflict serious injury and even blindness on people that come into contact with the plant. The sap of giant hogweed contains a toxic chemical which sensitises the skin and leads to severe blistering when exposed to sunlight. The burns can last for several months and even once they have died down the skin can remain sensitive to light for many years.
• Contact with the cut material in sunlight produces a reaction in almost everyone. The degree of symptoms will vary between individuals, but children are known to be particularly sensitive.
• The cut material remains active for several hours after cutting
• Blistering symptoms occur after 24-48 hours post exposure, and dense post-inflammatory hyper-pigmentation is visible after 3-5 days and may persist for at least 6 years.
