Walkers advised to tread carefully
Poisons experts urge the public to take care when planning country and woodland walks this summer.
Poisons experts have issued a warning to walkers to take care when out on country or woodland walks and reduce their risk of snake bites.
The Health Protection Agency’s specialist commissioned National Poisons Information Service (NPIS) is urging members of the public to take care and respect any wildlife they may come across - especially snakes.
Adders are the only venomous snakes in England, Scotland and Wales.
The NPIS says about half of bites occurred when a snake was picked up.
“Adder numbers have decreased in recent years so they are rare but still present in certain areas,” says Professor Simon Thomas, the director of NPIS Newcastle.
“They usually keep well out of sight, but in the summer months are active because the weather is warmer. Because they are well camouflaged people can accidentally tread on them, which is when they can bite. They can also bite if picked up.”

He added: “The bite can have very nasty effects, especially in smaller children – so it’s best to take care when out walking, wear appropriate footwear for the terrain and do not handle any snakes. Sometimes the venomous adder can be mistaken for non-venomous species such as the grass snake or smooth snake, making people think it is safe to pick them up.
“Snake bites do not always lead to the injection of venom into the wound. When no venom is released there is always a risk the wound may become infected but the anxiety caused to the patient is often the greatest health concern.
“When an adder bite does deliver venom it can cause local pain, tenderness, swelling and bruising which can spread. If a child is bitten, effects may be seen across the whole body.”
Professor Thomas said: “Although almost all poisonings from adder bites produce relatively minor effects the illnesses they lead to can be extremely unpleasant. And it’s worth remembering that the effects from these bites can be much more serious, though this is rare.
He added: “Because of this our advice is simply to do what you can to minimise your exposure. Do go out and enjoy the countryside. That’s really important.
“But if you are going somewhere with large areas of open space, just think about what you’re doing and most importantly of all, if you come across an adder, or indeed any snake or reptile, give it the respect it deserves as a wild animal and leave it alone.”
Anyone bitten by a snake should seek urgent medical attention.
