Introduction

A snake will sometimes bite in self-defence if disturbed or provoked.

Most snake bites occur when someone accidentally steps on a snake while walking in the countryside.

Some snakes are venomous and can inject venom containing toxins as they bite. A bite from a venomous snake is a medical emergency because it can be deadly if not treated quickly.

In the UK, adders (see photo) are the only venomous snakes found in the wild.

People also keep foreign (exotic) venomous snakes, sometimes illegally.

Exotic snakes have been known to bite while being handled carelessly, or when they escape from their cages.

There's also a risk of being bitten while travelling abroad to tropical countries.
