Salmonella linked to bearded dragons: a US outbreak shows risk without direct contact
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Many households assume that keeping children from touching the bearded dragon is enough to prevent salmonellosis. A 2025 report from US public health authorities shows that rule alone does not always work (, doi 10.15585/mmwr.mm7431a1). Find our other guidance in the reptile care and grooming section.

An outbreak that hit the youngest hardest
Xiaoli and colleagues documented an outbreak of the Salmonella Cotham strain, already responsible for an earlier wave some years prior, which resurfaced in 2024 with 27 confirmed cases spread across 14 US states. Among the 26 cases where age was known, 65% involved children under five, a group particularly vulnerable to severe salmonellosis. The investigation found a bearded dragon in the household in nearly all affected cases.
Indirect contact, an underestimated route
The most striking part of the investigation concerns how several children were exposed: nine parents or caregivers of a child under five reported that the child had no direct contact with the bearded dragon at all, but had contact with an adult who had handled the animal or touched its enclosure, or had spent time in a room where the reptile roamed freely. The bacteria can therefore spread through hands, clothing or surfaces, without a child ever laying a hand on the animal itself.
What the investigation can't tell us
An outbreak investigation like this one relies on cases that were reported and then lab-confirmed: it doesn't measure how often contamination actually occurs across every household that owns a bearded dragon, the vast majority of which never develop an identified symptom. Nor can it say whether this particular strain, Cotham, circulates more widely among farmed bearded dragons than other Salmonella strains, or pin down with certainty the original route of contamination for each case.
What this means in practice
The practical takeaway goes beyond simply "don't let the child touch the reptile": it's also worth keeping the bearded dragon from roaming freely through living spaces in a household with an infant, keeping the enclosure and its equipment away from food-preparation areas, and washing hands thoroughly — or even changing clothes — after any handling, before picking up a baby.

Frequently asked questions
Should a household rehome its bearded dragon if a baby is on the way?
No, the investigation doesn't recommend that: it points to specific hygiene measures worth reinforcing rather than a ban on reptiles cohabiting with young children.
Can a bearded dragon that looks perfectly healthy still spread salmonella?
Yes: like most reptiles, a bearded dragon can carry the bacteria without showing any symptom at all, which is exactly why consistent hygiene matters more than watching the animal for signs of illness.
