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.
