CHILDREN are being left in severe pain and with blistering skin after touching an extremely toxic plant growing in Worcestershire.

Giant hogweed's sap is extremely toxic to the skin in sunlight, making it a danger to public health, and cases are often reported in the summer holidays when young people encounter it.

The invasive plant was spotted in Worcester, Malvern and other areas across the county last month.

Coming into contact with any part of the non-native weed, followed by exposure to sunlight, can cause severe discomfort and blistering to the skin.

Dr Peter Fitzsimons, technical manager of the Property Care Association's invasive weed control group, said: “Each year we hear of people who are injured by Giant hogweed and quite often it is children who encounter it while out playing in the summer holidays.

“Our advice is to stay away from this plant and not allow its toxic sap to come into contact with the skin in the sunlight.

“The sap can also be transferred via touch, so it can affect somebody else through clothing and footwear.

“Symptoms include a rash, itching and blisters where skin comes into contact with it. 

“In some cases, the blistering can be so severe that urgent medical attention is required.

“The situation is made particularly serious as this can become a long-term condition, an allergic response called ‘sensitisation,’ which can recur over some time, with the rash and the itching coming back every time the skin is exposed to sunlight.

“Where exposure has occurred to the skin, we recommend washing the affected area, covering it up and seeking medical advice immediately.”

Capable of reaching a height of five metres, Giant hogweed has a five to eight-centimetre diameter stem and a large, white, umbrella-shaped flowering head.

Its leaves, which are sharply serrated or divided, can reach up to two metres in width, while the stem is usually covered in bristles and has blotchy purple markings.

The plant can be confused with UK’s native hogweed, but this plant is much smaller in size and its leaves have a smoother outline.
