## Resource

When every obvious test comes back negative, investigators have to look for another way to prove what caused the outbreak. So this episode takes a step sideways, from Bozeman, Montana to a small mountain village in the French Alps, where researchers faced a different kind of mystery: a cluster of ALS cases with no clear cause. What they found there may help explain how scientists can link a mushroom to a devastating illness, even without finding a toxin. In Episode 4 of A Morel Dilemma , we follow the investigation into Montchavin, mushrooms, environmental exposure, and the kind of epidemiologic detective work that becomes necessary when the lab tests do not give you the answer.
