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.
