Crested geckos have become increasingly popular as pets due to their unique appearance and ease of care.
However, there have been concerns about whether or not these animals carry the bacteria known as Salmonella.
Salmonella is a type of bacteria that can cause illness in humans and can be transmitted through contact with infected animals or their environment.
This article will explore the question of whether or not crested geckos carry Salmonella.
We will look at the potential risks associated with handling these animals and how to minimize those risks.
Do Crested Geckos Carry Salmonella?
There have been some reports of Salmonella infections associated with crested geckos.
However, it is important to note that not all crested geckos carry Salmonella, and the risk of infection can be minimized with proper hygiene practices.
In general, reptiles and amphibians are known to carry Salmonella bacteria in their digestive tracts, which can be shed in their feces.
If humans come into contact with the feces or environment contaminated with the bacteria, they can become infected with Salmonella.
While there is no definitive answer to whether all crested geckos carry Salmonella, studies have shown that a significant percentage of captive reptiles, including crested geckos, carry the bacteria.

However, it is important to note that the risk of infection can be minimized through proper hygiene practices, such as washing hands thoroughly after handling the animal or cleaning its enclosure.
It is also important to note that children, the elderly, and individuals with weakened immune systems are at a higher risk of developing serious illnesses from Salmonella infections.
Therefore, if you are considering owning a crested gecko or any other reptile or amphibian.
It is important to weigh the potential risks and take appropriate precautions to minimize those risks.
How Do Crested Geckos Carry Salmonella?
Crested geckos, like other reptiles and amphibians, can carry Salmonella bacteria in their digestive tracts.
The bacteria can be shed in their feces, and can then be spread to other animals or humans through contact with contaminated surfaces or objects.
Some of the ways that crested geckos can carry and spread Salmonella include:
Contact with contaminated surfaces
If a crested gecko comes into contact with a surface or object that is contaminated with Salmonella, the bacteria can stick to its skin or feet.
When the gecko is handled or moves to a new surface, it can then spread the bacteria to other surfaces or objects.
Fecal contamination
Crested geckos can shed Salmonella bacteria in their feces, which can contaminate their enclosure, food, and water.
If humans come into contact with contaminated surfaces or objects, they can then become infected with the bacteria.
Direct contact
If a person handles a crested gecko that is carrying Salmonella bacteria, the bacteria can be transferred to the person’s skin.
If the person does not wash their hands thoroughly, they can spread the bacteria to other surfaces or objects, potentially infecting other people.
Not all crested geckos carry Salmonella, but it is still important to practice good hygiene when handling them or cleaning their enclosure. This can help to minimize the risk of spreading Salmonella or other harmful bacteria.
Can You Be Infected By Salmonella?
Yes, humans can be infected with Salmonella bacteria. Salmonella is a type of bacteria that can cause illness in humans and is a common cause of foodborne illness.
Symptoms of a Salmonella infection can include fever, diarrhea, and abdominal cramps.
The symptoms can be mild or severe, and the illness can last anywhere from a few days to several weeks.
In severe cases, Salmonella infection can lead to hospitalization or even death, especially in young children, the elderly, and individuals with weakened immune systems.
Salmonella bacteria can be transmitted to humans through a variety of sources, including contaminated food or water, contact with infected animals, or contact with surfaces or objects contaminated with the bacteria.
Reptiles and amphibians, including crested geckos, are known carriers of Salmonella bacteria, and handling these animals or their environment without proper hygiene practices can increase the risk of infection.
To minimize the risk of Salmonella infection, it is important to practice good hygiene, such as washing hands thoroughly with soap and water after handling reptiles or their environment, cooking food to the appropriate temperature, and avoiding cross-contamination of food.
If you experience symptoms of a Salmonella infection, it is important to seek medical attention promptly.
