The CDC (Center for Disease Control and Prevention) reported an outbreak of salmonella in several states that occurred in September of 2011. The states involved are Alabama, Indiana, Michigan, Minnesota, Ohio and Washington. The outbreak is attributed to hedgehogs purchased from multiple breeders.
While all reptiles carry salmonella, it is not known if all hedgehogs are carriers. This does not mean that if you have a pet hedgehog that you should get rid of it or that you will be infected with salmonella.
There is a very simple way to avoid salmonella contamination. After handling your pet or any of his/her equipment, simply wash your hands thoroughly with soap and water.
By far, the largest majority of incidences of salmonella infection occur from contaminated food.
