    A Morel Dilemma: Episode 2 — Investigations and Falsehoods

    As reports of severe illness and death come in, the Bozeman outbreak moves from medical mystery to full public health investigation. Local and state investigators race to identify the source, shut down the risk, interview patients, collect food samples, and figure out whether anyone else could still be in danger. The early signal points toward one unlikely ingredient: morel mushrooms. But for toxicologists, that raises more questions than answers. Morels are supposed to be edible. Rapid vomiting and diarrhea usually suggest foodborne illness, not a deadly mushroom poisoning. So investigators have to ask the question that will drive the rest of the series: is the morel really the culprit, or is something else hiding in the meal? In Episode 2 of A Morel Dilemma, we meet the public health team on the front lines, hear how the outbreak was contained, and begin testing the first theories behind what made diners so sick.

    A Morel Dilemma: Episode 1 — Outbreak in Bozeman

    A deadly outbreak begins with a single meal at a sushi restaurant in Bozeman, Montana. Within hours, diners develop severe nausea, vomiting, and diarrhea. Some collapse. Two people die. At first, it looks like food poisoning, but investigators quickly notice one strange ingredient connecting many of the sick patients: morel mushrooms. In the first episode of A Morel Dilemma, we meet the people caught in the earliest moments of the outbreak and begin following the investigation as it unfolds in real time. What starts as a suspected restaurant-associated illness quickly becomes a much stranger question: how could a prized edible mushroom, eaten for centuries, suddenly be linked to death? This is not a retrospective summary. It is the beginning of a poisoning mystery, told the way investigators experienced it: with urgency, uncertainty, and more questions than answers.

    Gas Station Heroin? Kratom, Regulation, and Recovery — A Co-Broadcast with the Kratom Sobriety Podcast

    In this special co-broadcast episode, The Poison Lab joins forces with The Kratom Sobriety Podcast for a deeper conversation about kratom, regulation, addiction, recovery, and what poison center data can tell us about real-world harm. Kratom is a plant-derived substance that contains mitragynine and 7-hydroxymitragynine, compounds with opioid-like effects. It is sold in many forms, including powders, capsules, drinks, tonics, and concentrated extracts, often in gas stations, smoke shops, and online. For many people, kratom is encountered with little warning about its risks, including dependence, withdrawal, and toxicity. Study NewsThis episode grew out of our newly published study in Addiction, which examined kratom-related poison center calls across states with different legal approaches: states with bans, states with kratom consumer protection acts, and states with no specific regulation. The study began with a real policy question in Wisconsin: is the public better protected by prohibition, by regulated access, or by leaving kratom largely unregulated? As clinical toxicologists and poison center clinicians, our goal was not to write policy, but to add objective data to a debate that often moves faster than the evidence. Ryan discusses how that question led to a broader debate within medical toxicology and poison center circles: What are the harms of prohibition? What are the risks of unfettered access? Is regulation safer than a ban? And what can poison center data actually tell us about those questions? After the study was published, people reached out from several directions: journalists, policymakers, people concerned about the risks of prohibition, and people who had experienced harm from easy access to kratom. That included the team behind The Kratom Sobriety Podcast, who wanted to talk about the study and the lived experience of kratom dependence and recovery. The conversation highlights both the data and the human side of the issue: people who developed kratom dependence, struggled to stop, and found their way into recovery. The episode explores why policy decisions around kratom are so difficult, why easy access to opioid-like substances can be dangerous, and why lived experience matters alongside epidemiologic data. Topics covered include:What kratom is and why it is often called a “gas station drug”Mitragynine, 7-hydroxymitragynine, and opioid-like effectsKratom dependence, withdrawal, and recoveryHow poison centers track emerging substancesDifferences between state bans, consumer protection acts, and unregulated accessWhat poison center data can and cannot tell usWhy kratom policy is more complicated than “ban it” versus “leave it alone”The importance of listening to people with lived experience This episode is a longer-form conversation about science, policy, toxicology, and recovery. It is not medical advice, and it is not meant to tell any individual person what they should do. But it is meant to bring more evidence, nuance, and humanity into a debate that needs all three. If you or someone you know is struggling with kratom or any substance use, help is available. In the United States, you can contact the SAMHSA National Helpline at 1-800-662-HELP.

    Outbreak: 75 Fatalities After a Funeral Poisoning in Mozambique

    In this episode of The Poison Lab Outbreak, Ryan talks with Dr. Alaina Steck about a devastating mass poisoning in Mozambique that began at a funeral and ultimately sickened more than 200 people, with a fatality toll of over 70. Early reports blamed crocodile bile. Others suspected intentional poisoning. But as the investigation unfolded, the clinical picture, timeline, and exposure history did not fit neatly with the early theories. Dr. Steck, then a medical toxicology fellow at Emory, joined a CDC-supported outbreak investigation team sent to Mozambique. She walks through what it was like to investigate the outbreak on the ground, including the overwhelmed rural health center, limited medical records, scarce biological and environmental samples, early toxicologic hypotheses, and the eventual role of comparative food testing in identifying the cause. This episode explores the real-world uncertainty of outbreak investigation: incomplete data, competing theories, community fear, and the importance of epidemiology, toxicology, public health, and analytical chemistry working together. Topics CoveredMass poisoning investigation in rural MozambiqueEarly reports of crocodile bile and suspected intentional poisoningClinical presentations including GI symptoms, seizures, pulmonary edema, liver injury, kidney injury, and multisystem diseaseChallenges of interpreting sparse medical records during a mass casualty eventHow toxicologists approach possible intentional poisoningWhy exposure history and timing matter in outbreak investigationThe importance of control samples in analytical testingLessons for clinicians, poison centers, and public health teams GuestDr. Alaina Steck Medical toxicologist, Emory University Former medical toxicology fellow involved in the CDC-supported investigation of the Mozambique outbreak Resources (Spoilers)Outbreak paperU.S. Case Instagram @tox_talk • Twitter @LabPoison • Email toxtalk1@gmail.com Disclaimer: The Poison Lab is for educational purposes only and does not provide medical advice.
