Rare Salmonella Strain Linked to Bearded Dragons Sickens Dozens Across the US
Table of Contents
A recent outbreak of Salmonella enterica Cotham, an unusual strain not typically associated with foodborne illness, has sickened 27 people in 14 states, according to a report released by the Centers for Disease Control and Prevention (CDC) in late 2024 and detailed further in the CDC’s Morbidity and Mortality Weekly Report. The surprising source? Pet bearded dragons.
Understanding Salmonella Cotham
While Salmonella is commonly linked to contaminated food – think lettuce recalls or undercooked poultry – Salmonella enterica Cotham is a rarer serotype with a wider range of hosts. Beyond the recent U.S. outbreak, Cotham has been identified in a central bearded dragon at a zoo in Norway, a bearded dragon and a Hermann’s tortoise in the Czech Republic, and even in livestock like poultry and cattle in Nigeria.
This widespread distribution is concerning. Scientists believe reptiles and agricultural animals may act as reservoirs for the bacteria.Adding to the worry, a 2023 isolate from the Czech Republic demonstrated resistance to tetracycline, a commonly used antibiotic, highlighting the potential for treatment complications should the serotype become more prevalent.
Protecting Your Family: What Reptile Owners Need to Know
If you share your home with a bearded dragon or other reptile, the CDC recommends taking the following precautions. These aren’t about eliminating reptile ownership, but about minimizing risk, especially for vulnerable populations.
- Limit Roaming: Prevent reptiles from freely roaming throughout your home, notably in areas frequented by infants or used for food preparation.
- Dedicated Supplies: Keep all reptile-related equipment and supplies strictly separate from items used for babies or cooking.
- Hygiene is Key: Wash your hands thoroughly with soap and water after handling reptiles or their enclosures. Change clothes before handling infants or preparing food.
- Safe Cleaning Practices: Never clean reptile cages or bowls in the kitchen sink.
A particularly alarming aspect of this outbreak is that many infants contracted the infection without direct contact with the reptiles themselves. The bacteria spread indirectly – via contaminated hands, clothing, or surfaces. This underscores the importance of rigorous hygiene practices.
The Bigger Picture: One Health and the Reptile Trade
This outbreak isn’t simply a public health issue; it’s a stark illustration of the interconnectedness of animal, human, and environmental health – a concept known as One Health. The persistence of Salmonella Cotham across continents and host species demonstrates the potential for pathogens to exploit vulnerabilities in our systems.
The current system often treats reptiles as commodities, neglecting both microbial risks and animal welfare. A shift is needed – one that prioritizes higher standards of hygiene, rigorous testing, and complete transparency throughout the reptile supply chain. We must recognize that the next outbreak isn’t a matter of *if*, but *when*. Pathogens are opportunistic, and our responsibility is to proactively close the gaps that allow them to reach our most vulnerable populations.
