About this episode

Investigators collaborate with the CDC and FDA to determine the cause of a food poisoning outbreak linked to morel mushrooms, facing challenges as tests return negative results.

With the restaurant closed and the first interviews underway, investigators bring in the CDC and FDA to help answer the question at the center of the outbreak: what actually made people sick? The leading suspect is still the morel mushroom, but proving that is not simple. The symptoms could fit bacterial food poisoning, spoiled fish, a chemical contaminant, a mislabeled spice, or even a toxic mushroom mixed in by mistake. So the team starts testing everything they can: patient samples, food samples, bacteria, pesticides, heavy metals, classic mushroom toxins, and more. In Episode 3 of A Morel Dilemma , we go inside the science of a poisoning investigation and ask what happens when every obvious test comes back negative. Because when there is no toxin to find, the mystery does not end. It gets harder.
