The week of November 17, 2025, salamander owners reported sick and dying animals from a private collection. Scientists quickly got involved to figure out what was making these salamanders ill!
The good news? Researchers ruled out the scary pathogens everyone worries about—Bsal, Bd (chytrid fungus), and Ranavirus. But the challenging news? They’re still working to identify what’s actually causing the illness. Scientists suspect it could be a fungus, virus, or bacterium, possibly from another continent.
As of December 18, 2025, the outbreak appears limited in scope. Sick salamanders have been quarantined, and experts are monitoring the situation closely.
What Does This Disease Look Like?
If you keep salamanders, watch for these symptoms:
- Abnormal skin shedding or sloughing
- Skin lesions or ulcerations
- Dark, dry patches on the skin
- Sluggish behavior
- Reduced appetite
- Bleeding
So far, this disease has only appeared in salamanders from the genus Salamandra. Scientists don’t yet know if other salamander species are at risk.
How HTI Is Helping Contain the Outbreak
The Healthy Trade Institute is leading forward tracing efforts to identify businesses and pet owners who might have been exposed to this pathogen. HTI is working directly with the North American Bsal Task Force, University of Tennessee researchers, and the USGS National Wildlife Health Center to contain the disease and determine the cause.
This is exactly what HTI does—we connect businesses and pet owners with scientific experts when health issues arise. We help coordinate testing, provide guidance on biosecurity practices, and support disease response efforts. And importantly, we keep your information confidential.
What Should You Do to Protect Your Salamanders from Disease?
If you own salamanders or sell amphibians, here’s what experts recommend:
- Watch your animals closely. Look for the symptoms shown in this YouTube video. Early detection helps prevent the spread to other animals.
- Report unusual symptoms. If you see signs of illness in your salamanders, contact HTI immediately. Don’t move, transport, or release potentially sick animals without professional guidance. Reach out to Matt Gray, HTI’s CEO and President, at mgray@healthytrade.org or call 865-385-0772.
- Practice good biosecurity. Wash your hands after handling animals. Use nitrile gloves when feeding or cleaning and change them between different habitats (tanks, enclosures). Keep separate spaces for food preparation and animal care.
- Quarantine new animals. Always quarantine newly acquired amphibians before introducing them to your existing collection. Watching animals for signs of disease for a month can prevent disease spread. It’s also a good idea to test new animals for known diseases, which the HTI can do.
- Buy from reputable sources. Acquire animals from businesses that prioritize health testing and biosecurity, such as HTI Certified Business Members
- Businesses, Get HTI certified. Join HTI’s Certification Program to access pathogen testing, biosecurity training, and expert consultation. Certified members have the tools and support to prevent outbreaks before they start!
Why This Matters for the Entire Herp Community
This salamander pathogen outbreak shows why disease monitoring matters! When someone noticed sick animals and reported it quickly, experts could respond fast. That rapid response likely prevented this unknown pathogen from spreading throughout the U.S. pet trade.
The disease can spread between salamanders if they’re housed together or if good hygiene practices aren’t followed. Scientists believe animals without symptoms could still carry and transmit the disease, which is why monitoring and containment are so important right now.
How HTI Certification Helps Prevent Outbreaks
HTI-certified businesses follow science-backed protocols that catch diseases early:
- Pathogen testing of newly acquired animals before they leave quarantine
- Biosecurity training on disease recognition and prevention
- Access to diagnostic laboratories for quick, accurate testing
- Expert consultation when unusual symptoms appear
- Response protocols for isolating and treating sick animals
If the affected breeder had been an HTI member with these practices in place, routine testing might have caught this pathogen before any animals got sick and disease spread.
No Panic Needed—Just Vigilance
There’s no evidence this disease affects humans or non-amphibian pets. The outbreak appears controlled. But it’s a good reminder that staying alert protects both your animals and the broader herp community.
The early detection and rapid response from multiple partners, businesses, and pet owners demonstrates that cooperative monitoring works. When we all watch out for disease and report concerns, we protect captive collections and wild native species.
