The CDC reports at least 20 cases of Salmonella Tyhpimurium infection linked to pet hedgehogs in the past two years. There was one case in Oregon, and one fatality in Washington state.
Epidemiologic, laboratory, and traceback findings have linked this outbreak of human Salmonella infections to contact with pet hedgehogs purchased from multiple hedgehog breeders in different states.
To reduce the risk of infection, it's important to wash your hands after handling hedgehogs or anything the animals come in contact with. This is especially important for children to do, as they can be more susceptible to infection. Parents should supervise handwashing for young children.
