One Person Infected With Salmonella Oranienburg Linked to Rattlesnake Pills, CDC and Kansas Officials Report
The Centers for Disease Control and Prevention (CDC) and the Kansas Department of Health and Environment have confirmed a single case of Salmonella Oranienburg infection potentially linked to the consumption of rattlesnake pills, according to a joint statement released on April 5, 2024. The patient, a 42-year-old Kansas resident, reported taking the supplement in late March before developing symptoms, including diarrhea, fever, and abdominal cramps, which led to hospitalization.
What Is Salmonella Oranienburg?

Salmonella Oranienburg is a rare serotype of the Salmonella bacteria, typically associated with foodborne illness. It spreads through contaminated food or water, though animal products—such as reptiles—are common carriers. The CDC notes that while most Salmonella infections resolve within a week, severe cases can lead to hospitalization or long-term complications, particularly in immunocompromised individuals.
Why Rattlesnake Pills Pose a Risk
Rattlesnake pills, marketed as dietary supplements for purported health benefits, are often produced without stringent regulatory oversight. The U.S. Food and Drug Administration (FDA) has warned that such products may harbor pathogens due to inadequate processing or storage. In this case, investigators are examining whether the rattlesnake source material was contaminated during harvesting or manufacturing. “These supplements are not subject to the same safety standards as prescription medications,” said Dr. Sarah Thompson, an FDA spokesperson.
Tracking the Outbreak
The Kansas Department of Health and Environment is conducting a traceback investigation to determine the supplement’s origin. As of April 5, no additional cases have been reported, but officials caution that the infection could spread if others consumed the same batch. “We’re urging consumers to avoid unregulated supplements and to report any illness after taking them,” said Dr. Michael Reynolds, a state health official.
What Should Consumers Do?
The CDC recommends that individuals who have taken rattlesnake pills or other unconventional supplements and subsequently experience gastrointestinal symptoms seek medical attention. Additionally, consumers are advised to check the FDA’s list of banned or unapproved products and consult healthcare providers before using alternative remedies.
Broader Implications for Supplement Safety

This case highlights ongoing concerns about the safety of dietary supplements. A 2022 study in *JAMA Internal Medicine* found that over 20% of supplements tested contained undeclared pharmaceutical ingredients or contaminants. While the CDC does not regulate supplements, it collaborates with the FDA to monitor adverse events. “Consumers deserve transparency,” said Dr. Linda Nguyen, a public health researcher. “Regulatory gaps leave room for risk.”
How to Identify Safe Supplements
To reduce risks, the FDA advises:
- Look for supplements with the U.S. Pharmacopeia (USP) seal, indicating third-party testing.
- Avoid products sold through unverified online vendors or without clear labeling.
- Report adverse effects to the FDA’s MedWatch program.
Summary and Next Steps
The Kansas case underscores the potential dangers of unregulated supplements, even those derived from seemingly “natural” sources. While no broader outbreak has been identified, health officials emphasize vigilance. Consumers are encouraged to prioritize evidence-based treatments and consult healthcare professionals before using alternative remedies. As the investigation continues, updates will be shared through the CDC and Kansas DHSE websites.
