A Morel Dilemma Preview: Supporting Member Bonus Episodes
This preview features the opening conversations from two supporting member bonus episodes in The Poison Lab outbreak series.First, we head to Ontario, where a mass aconite poisoning unfolded after a restaurant spice was contaminated with one of the most dangerous plant toxins in the world. Then we travel to Australia, where the poppy seed supply was contaminated with thebaine, triggering seizures and severe poisonings across the country.These are the kinds of outbreak stories that show how quickly a routine exposure can become a public health emergency, and how clinicians, poison centers, laboratories, and public health teams work together to figure out what went wrong.

A Morel Dilemma Bonus Radio Co-Broadcast: Ryan Feldman on WTMJ Conversations — Morels, Mushroom Poisoning, and the Story Behind A Morel Dilemma
In this bonus episode of A Morel Dilemma, Ryan shares his recent interview on WTMJ Conversations with Libby Collins.The conversation goes behind the scenes of the series and explores why Ryan spent two years investigating the 2023 Bozeman, Montana morel mushroom outbreak, one of the strangest poisoning outbreaks in recent history. Ryan discusses how the outbreak challenged long-held assumptions about morels, why mushroom poisonings are not all the same, and how public health investigators work through uncertainty when people become seriously ill from a shared exposure.The episode also covers mushroom foraging safety, the difference between true and false morels, why raw or undercooked morels can be dangerous, and what Wisconsin poison center toxicologists commonly see during mushroom season. Ryan also talks about broader poisoning outbreaks, including vape-associated lung injury, contaminated synthetic cannabinoids, pediatric exploratory ingestions, THC edibles, and other toxicology problems that show up far more often than mushrooms.This is a good episode for anyone who wants a more conversational introduction to A Morel Dilemma, the public health stakes behind poisoning outbreaks, and the strange world of mushroom toxicology.Topics covered include:Why foraging is becoming more popularWhy you should never eat a mushroom unless you are 100% sure of its identificationTrue morels vs. false morelsWhy morels should never be eaten raw or undercookedThe Bozeman morel mushroom outbreakHow investigators think through foodborne poisoning mysteriesMushroom poisonings seen by poison centers in WisconsinDeath caps, destroying angels, and amatoxin poisoningPediatric poisoning risks, including laundry pods, THC edibles, and household chemicalsWhy poisoning outbreaks are difficult to recognize and investigateWhat A Morel Dilemma is really trying to uncoverYou can learn more about the series at ThePoisonLab.com or TheMorelDilemma.com.A Morel DilemmaSupport the showReview the show where ever your listeningGet Messages from Toxo (Join the Newsletter!)Join as a supporting memberAd free episodesBonus content and early accessDiscounts and give aways on GOTA PICCEM Mushroom card gameThe GOTTA PICCEM Poisonous Mushroom Game!The Poisonus Fungus Amongus Children's Book!Full book reading (6 minutes!)Tox trinkets (Rep the show at home!)Reach the showEmail: Toxtalk1@gmail.comMore Show ResourcesRyan's Medical Games and ResourcesShow Website

A Morel Dilemma: Episode 7 — What We Know Now
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 ending is not as simple as naming a culprit. Morels have now been linked to severe illness and death, yet we still do not know the toxin, why some people are more vulnerable, or exactly how much cooking is enough.Episode 7 brings the story back to what matters most: what we know, what we still do not know, and what has to happen next so this does not happen again.A Morel DilemmaSupport the showReview the show where ever your listeningGet Messages from Toxo (Join the Newsletter!)Join as a supporting memberAd free episodesBonus content and early accessDiscounts and give aways on GOTA PICCEM Mushroom card gameThe GOTTA PICCEM Poisonous Mushroom Game!The Poisonus Fungus Amongus Children's Book!Full book reading (6 minutes!)Tox trinkets (Rep the show at home!)Reach the showEmail: Toxtalk1@gmail.comMore Show ResourcesRyan's Medical Games and ResourcesShow Website

A Morel Dilemma- Bonus: Emergency Mushroom Identificaiton
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: who to call, why online apps and social media can be dangerous, and how poison centers work with trained mycologists and mushroom identification experts when the stakes are high.Because in a mushroom emergency, the answer is not to keep scrolling. It is to call the Poison Center at 1-800-222-1222.

A Morel Dilemma: Episode 6 — The Signal
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 not stop there.In Episode 6 of A Morel Dilemma, we follow that signal beyond Montana and ask whether this was truly an isolated outbreak, or whether morels have been causing severe poisonings for years without anyone recognizing the pattern. We also meet the researchers now trying to answer the harder question: if morels are responsible, what exactly is happening inside this mushroom?The mystery is no longer confined to one restaurant. It is starting to spread.Select referecnces:Dr. Vodovar's StudySwiss Poison Center StudyPeter DaytonA Morel DilemmaSupport the showReview the show where ever your listeningGet Messages from Toxo (Join the Newsletter!)Join as a supporting memberAd free episodesBonus content and early accessDiscounts and give aways on GOTA PICCEM Mushroom card gameThe GOTTA PICCEM Poisonous Mushroom Game!The Poisonus Fungus Amongus Children's Book!Full book reading (6 minutes!)Tox trinkets (Rep the show at home!)Reach the showEmail: Toxtalk1@gmail.comMore Show ResourcesRyan's Medical Games and ResourcesShow Website

A Morel Dilemma: Bonus — The Bradford Hill Criteria & The Morel
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 step, looking at strength of association, timing, dose response, plausibility, consistency, specificity, and the places where the morel theory starts to strain.This is the deeper dive behind the trial: how toxicologists stress-test an outbreak theory when there is no smoking gun, no known toxin, and no easy answer.Select referencesCDC Bozeman Montana Outbreak DataRyan's paper on the Bradford hill criteria in EVALIA Morel DilemmaSupport the showReview the show where ever your listeningGet Messages from Toxo (Join the Newsletter!)Join as a supporting memberAd free episodesBonus content and early accessDiscounts and give aways on GOTA PICCEM Mushroom card gameThe GOTTA PICCEM Poisonous Mushroom Game!The Poisonus Fungus Amongus Children's Book!Full book reading (6 minutes!)Tox trinkets (Rep the show at home!)Reach the showEmail: Toxtalk1@gmail.comMore Show ResourcesRyan's Medical Games and ResourcesShow Website
