CDC Warns Pet Owners: Geckos Linked to Salmonella Outbreak – What You Need to Know

Introduction

The Centers for Disease Control and Prevention (CDC) has issued a critical Health Alert Network (HAN) warning about a multi-state Salmonella outbreak linked to pet geckos. While these small reptiles are beloved pets, they can carry Salmonella, posing serious health risks—especially to children, seniors, and immunocompromised individuals. Here’s what you need to know to stay safe.

CDC’s 2025 Health Alert: Key Details

The Scope of the Outbreak

As of March 2025, the CDC confirmed 8 Salmonella cases across 8 U.S. states, with investigations ongoing. The strain involved, Salmonella Muenchen, mirrors past outbreaks in Canada (2020–2024) tied to geckos, which caused hospitalizations and fatalities.

How the Outbreak Was Traced

Health officials linked cases through patient interviews and lab tests confirming matching Salmonella strains in humans and gecko environments. Reptiles like geckos naturally carry Salmonella in their intestines, shedding it through feces even when asymptomatic.

Understanding Salmonella and Its Link to Geckos

What Is Salmonella?

Salmonella is a bacteria causing diarrhea, fever, and stomach cramps. Symptoms appear 6 hours to 6 days post-exposure and can last a week. Severe cases may require hospitalization.

How Geckos Spread the Bacteria

• Geckos shed Salmonella in their feces, contaminating their skin, habitat, and surfaces.
• Handling pets, cleaning tanks, or touching contaminated items without proper hand hygiene can lead to accidental ingestion.

High-Risk Groups

Children under 5, adults over 65, and immunocompromised individuals face higher risks of severe complications like dehydration.

Why Are Geckos Common Salmonella Carriers?

Natural Hosts

Up to 90% of reptiles, including geckos, naturally carry Salmonella in their gut microbiome without showing symptoms.

Popularity + Misinformation

Geckos’ low-maintenance appeal often overshadows Salmonella risks. Pet stores may not emphasize hygiene protocols, leaving owners unaware.

Ideal Bacterial Environment

Warm, humid tanks and organic substrates (e.g., coconut fiber) create perfect conditions for Salmonella to thrive.

Historical Context: Past Reptile-Linked Outbreaks

• Canada (2020–2024): 25 Salmonella Muenchen cases (1 death); 36 Salmonella Lome cases.
• U.S. Trends: Turtles and bearded dragons have sparked similar outbreaks. In 2019, pet turtles caused a multi-state Salmonella scare.

CDC-Recommended Prevention Strategies

1. Hand Hygiene

Wash hands with soap for 20–30 seconds after handling geckos or their habitat. Use alcohol sanitizer if soap isn’t available.

2. Habitat Management

• Clean tanks weekly with bleach solution (1/3 cup bleach per gallon of water).
• Avoid washing gecko supplies in kitchen sinks.

3. Safe Handling Practices

• Supervise children interacting with geckos.
• Never touch your face or eat while handling pets.

4. Household Awareness

Educate all family members and guests about Salmonella risks and prevention.

Conclusion: Responsible Pet Ownership Amid Risks

While geckos make charming pets, proactive hygiene is non-negotiable. Stay updated via the CDC’s alerts, and seek medical care if Salmonella symptoms arise post-exposure. By balancing affection with caution, you can safely enjoy your reptilian companion.
