Solving the case of the poison processed peanuts took marathon work by federal scientists, clues in Canada, Oregon, Ohio and Connecticut, and a breakthrough in Minnesota at the hands of public health hotshots known as Team Diarrhea.

The peanut case quickened the pulse of federal scientists on Nov. 12, more than a month after people started getting sick, when the federal Centers for Disease Control detected a cluster of salmonella cultures with an unusual genetic fingerprint reported from 12 states.
That was "a blinking light," Dr. Ali Khan, assistant surgeon general, told Congress.
PulseNet, a national network for finding patterns in widely dispersed foodborne bacterial illness, offered additional clues when four more states reported the cluster.
Then on Dec. 2, scientists began examining a second salmonella cluster with a similar genetic makeup, reported from 17 states. The two clusters turned out to be the same.
"December is when the alarm bells go off," Kahn said.
