The Time: January 1996
The Place: Denver, Colorado
The Mystery:
Over 50 kids went to their doctor because they had bloody diarrhea, painful cramps, and a high fever.
The doctors figured out that all these people had Salmonella, a disease caused by a kind of bacteria. (Even though this disease has the word "salmon" in it, it has nothing to do with fish. Salmonella gets its name from the guy who discovered it -- Daniel Elmer Salmon.)
Even though salmon didn't cause the illness, the folks at the Centers for Disease Control and Prevention guessed that something fishy was going on. Why did all these people get sick at the same time?
