The Poison Lab

In this episode of The Poison Lab, host Ryan Feldman is joined by medical toxicologist Damilola Idowu‑Ellsworth for a fast-moving, case-heavy conversation packed with clinical pearls, listener participation, and classic toxicology weirdness. The show opens with listener guesses for the previously released mystery case before diving headfirst into a rapid-fire series of Stump the Toxicologist cases—questions pulled straight from the internet and real-world toxicology problem-solving. Along the way, Ryan and Dami cover everything from rodenticides and drug-testing myths to how to clean a benzodiazepine bottle, plus one of the most toxic substances you’ve probably never heard of. One lucky listener also wins a copy of Poisonous Fungus Amongus, and a shout-out to the newly released second edition featuring photography from expert mycologists. Skip the listener guesses and jump straight to the mystery toxin: 38:15 The rest of the episode is Dr. Idowu and Ryan discuss the topics below. Looking for timestamps?

Hey everybody, you’re listening to The Poison Lab—well, almost. We’ve got a new episode coming next week, but we’re running a little behind on our usual release schedule because… life happens. That said, if you’re looking for some toxicology content right now, I’ve got you covered. Recently, I had the chance to appear on two local and state radio shows talking about one of my favorite topics: mushroom poisoning 🍄—and both were an absolute blast. 🌱 Garden Talk (Call-In Episode) (Ryan starts @ 1 hour and 14 min) The first appearance was on Garden Talk, a fun, live call-in show where we covered: GOTTA PICCEMPoisonous Fungus Among Us It was lively, unpredictable, and a great example of how curious people are about mushrooms once you open the door. 📻 Local Health Update Radio Segment After that, I joined a local radio health update to talk specifically about mushroom poisoning from a public-health perspective. It’s always interesting to hear how radio hosts approach such a niche topic—and how quickly it turns into something broadly relevant. 🔬 Want a Quick Toxicology Fix? If you’re itching for some Poison Lab content while you wait for the next full episode, these two appearances are a great place to start. And don’t worry—we’ll be back next week with a full episode and answers to our mystery case. Thanks, as always, for listening. Hope to see you there. — Ryan

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 medicine pharmacist, investigates how pharmaceutical-grade, thebaine-rich poppy seeds were mistakenly repackaged into the food supply—and how poison centers, clinicians, labs, and public health teams traced and contained the threat within days. You’ll hear firsthand from the experts who responded: Together, they walk us through the outbreak timeline—from the first ICU cases and puzzling “strych­nine-like” neuroexcitation to the multi-state investigation, product recall, and lessons for future foodborne poisonings.

From the mind of a toxicologist who treats real mushroom poisonings alongside doctors and poison centers comes Poisonous Fungus Amongus—a playful, rhyming adventure into the fascinating world of poisonous mushrooms! Inside, readers will find a colorful introduction to mushroom anatomy and ecology—learning the parts of a mushroom and discovering helpful hints for safe foraging and identifying dangerous look-alikes. Every species featured in these pages is a real poisonous mushroom, brought to life through vivid illustrations and engaging verse. This beautifully illustrated book goes beyond the basics, exploring how mushrooms grow, reproduce, and take shape in nature—from tiny spores to sprawling mycelium to the fruiting bodies we find in forests and fields. Through rhymes and clear explanations, readers learn to recognize essential mushroom features—caps, gills, pores, rings, bulbs (volvas), veils, warts, scales, spore prints, and gill types like free, adnate, and decurrent. Each detail helps distinguish the edible from the toxic—and shows how some features can fool us! The story encourages safe and curious observation: note each feature, dig gently to look for bulbs, observe nearby trees and seasons, and check for bruising or color changes. Along the way, readers also discover fungi’s hidden ecological roles, from tree-nurturing mycorrhizae to the saprotrophs that recycle the forest floor. With rhythm, rhyme, and a spark of scientific wonder, Poisonous Fungus Amongus blends accuracy with imagination—inviting kids and adults alike to explore and respect the natural world, while learning that curiosity and caution must always grow together when it comes to mushrooms. Perfect for young readers, nature lovers, teachers, and families who want to explore the mysterious and magical world of fungi!
