Public health experts report there have been at least four cases of Salmonella associated with bearded dragons in Britain in the last eight months.
Children are particularly at risk because they like to stroke and handle pet reptiles.
Bearded dragons have become popular as pets but their feces can contain Salmonella.
Owners of bearded dragons and other reptiles are advised to wash their hands thoroughly after handling them and clean down any surfaces, which they may have been in contact with.
