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 […]

In November 2022, hospitals across Australia began seeing patients with sudden rigidity, spasms, seizures—and in some cases cardiac arrest—after drinking homemade poppy seed tea. The source? Food-shelf poppy seeds contaminated with extraordinarily high levels of thebaine, an opioid alkaloid that acts nothing like morphine. In this Outbreak episode, host Ryan Feldman, clinical toxicologist and emergency

After weeks of investigation, the Bozeman outbreak is contained, but the questions it raised are much harder to close. In the final episode of A Morel Dilemma, we return to Montana to understand how investigators traced the mushrooms, looked for additional cases, communicated risk to the public, and worked to prevent another outbreak. But the

When someone eats a mushroom and starts to feel sick, the first instinct is often to figure out exactly what mushroom it was. But mushroom identification is harder, riskier, and more specialized than most people realize. In this bonus episode of A Morel Dilemma, we look at what actually happens after a possible mushroom exposure:

The Bozeman outbreak was the first loud signal, but it was not the only one. After the CDC report, toxicologists in other countries started looking back through their own poison center data and found something unsettling: more patients with severe illness after eating morels, including cases of shock, gastrointestinal bleeding, and death. And it did

In Episode 5, we put the morel mushroom on trial. This bonus episode shows how we built the case. Dr. Grant Comstock joins me for the full, unfiltered causation breakdown using the Bradford Hill criteria, a public health framework used to separate true causation from simple association. We walk through the CDC data step by

The case against the morel mushroom is starting to come together, but there are still major problems. Not everyone who got sick ate morels, and not everyone who ate morels got sick. If the mushroom is really the culprit, those gaps have to be explained. In Episode 5 of A Morel Dilemma, we put the

When every obvious test comes back negative, investigators have to look for another way to prove what caused the outbreak. So this episode takes a step sideways, from Bozeman, Montana to a small mountain village in the French Alps, where researchers faced a different kind of mystery: a cluster of ALS cases with no clear

In this bonus episode, we go deeper into the public health machinery behind a mass poisoning investigation. Dr. Michael Yeh, a medical toxicologist at the CDC’s National Center for Environmental Health, explains how the CDC gets pulled into unusual outbreaks, how poison centers and health departments help spot early signals, and what happens once a
