As Morel Season Peaks, New Investigative Series Follows the Deadly Morel Mushroom Outbreak That Shook a Montana Community

A Morel Dilemma traces a real-time public health investigation into a fatal restaurant outbreak, the prized mushroom at the center of it, and the unanswered questions that followed.

MILWAUKEE, WI — [June 3rd 2026] — Morel mushrooms are among the most beloved wild foods in North America. Every spring, foragers hunt them, chefs serve them, and mushroom enthusiasts celebrate them as a seasonal delicacy.

But in 2023, a deadly outbreak in Bozeman, Montana forced investigators to confront a baffling question: how does a mushroom people have eaten for generations suddenly become the prime suspect in a fatal mass poisoning?

That question is at the center of A Morel Dilemma, a new serialized investigative podcast from The Poison Lab, hosted by poison center toxicologist Ryan Feldman, PharmD, DABAT, FAACT.

The series follows the outbreak as it unfolded: first reports of severe illness, a restaurant shutdown, urgent patient interviews, food testing, public health alerts, and a growing mystery around a special sushi roll that contained morel mushrooms.

Multiple people became severely ill. Some were hospitalized. Two people died. At first, the possible explanations seemed familiar: foodborne bacteria, contamination, a toxic look-alike mushroom, or some hidden ingredient. But as investigators worked through the evidence, the case became stranger and harder to dismiss.

“Morels are one of those foods people think they understand,” said Feldman. “They are familiar, celebrated, and widely treated as edible. So when an outbreak investigation starts pointing toward them, the first reaction is disbelief. That disbelief is really where this series begins.”

Across the season, A Morel Dilemma brings listeners inside the investigation through interviews with affected families, local and state public health officials, CDC toxicologists, poison center experts, mycologists, analytical chemists, neurologists, and international researchers.

Rather than summarizing the outbreak after the fact, the series unfolds the way real poisoning investigations do: one clue at a time. Listeners follow the competing theories, the dead ends, the laboratory testing, the epidemiology, the clinical treatment decisions, and the debate among experts about what the evidence can and cannot prove.

Along the way, the series becomes more than a story about one restaurant outbreak. It opens a rare window into how poisoning outbreaks are recognized, tracked, treated, and investigated behind the scenes, from the first hospital calls to poison center consultation, public health interviews, national alerts, and laboratory searches for toxins that may not yet have a name.

“This is not just a story about mushrooms,” Feldman said. “It is a story about how public health works under uncertainty. How do you make decisions when people are sick, the stakes are high, and the answer is not obvious?”

The investigation also leads beyond Montana, into unsettling reports involving other mushrooms and the possibility that familiar species may not always behave the way experts expect. As the series follows the evidence, it raises an eerie question at the edge of toxicology and ecology: can mushrooms develop or reveal new toxicities that science has not fully recognized?

A Morel Dilemma follows a scientific and human mystery: how a celebrated delicacy became the focus of a fatal outbreak investigation, what that investigation reveals about the hidden machinery of public health, and why the story may change the way clinicians, investigators, and the public think about mushrooms.
